Is there an end to space. u would think so but if it stopped somewhere wot is past that. more space? weird. Or would ugo round in a circle. i think u would, like goin round the earth...

ah but that deos not explain is space ends. when u think of it its hard to pickture it going on for forever.

viper

Well, my philosophy is Space is eternal, Space is forever.  There is no end.  You'll just keep going and going and going....
The only real "end" would be space becoming emptier and emptier.  And at the "edge" of the universe you are in a midst of nothingness.  Void.  Oblivion.  An endless field of darkness.  Not even darkness, but pitch black.

well there u go

I think there's probably an end. Everything else we know of has an end. But many facts about space are still a mystery, so it's hard to say...

Well I think that there is an end, in that we can't get past a certain point without going faster than the spped of light but if we could break that rule then we would be set. It's hard to explain, but the universe is moving apart so fast that there are some stars that we will never be able to see. If you wanna understand then read a new scientist from awhile back.

No one knows, no one can be right, so why ask?

well i guess it must stop sumwhere

If you stood on any planet in space for intance say the moon and looked through a pair of binoculars and held up you other hand you would eventuly see yourself.

well i think there is aliens out there some where cuz if there isn't it is a big waste of space so there must be somethin else out there!!!

I also tend to think there are some other species in the galaxie, hopefully they are not Borg (yeah, 5 hours of daily Star Trek make you see things). Anyway, think about it: we don't even know for sure how far our solar system goes, there are trillions of systems in our galaxie and there are millions of galaxies in the unverse, as far as we can tell. Maybe there's an even bigger entity, so the point is: we'll never know. As far as the universe is concerned, Earth is a stupid rock where some parasites succeeded to evolve and exterminate themselves in the blink of an eye. Probably millions of other civilisations existed before us in other systems and millions more will exit after us, chances are we'll never know about it either. It's sad but that's a fact.

By the way, very nice pictures posted here. It's good to see a thread not talking about sex or cars .

Patchou

We already have the borg; Microsoft.

My 'e' key is sticking

i think i may have the answer

yes there WAS an end to space at the end to space at the end of this universe (which may seem unending because it is so big)
until a couple of years ago when scientists sent a laser beam into space (i dont know the full story so dont ask me) now if there was an end you would see the laser pass straight through. However it did not, it bounced off other things and reflected in different places etc. saying this means that there are parallel universes out there somewhere

so just think about it.............there could be another universe
exactly 100% the same as ours with the same milky way and exactly the same earth............with someone exactly like you...............doing exactly the same thing as you right now this very millisecond and thinking about exactly the same thing.

think about it and post a reply(or send me an email)

Also when you see light i think most of them  are beams of moving light. then where did they come from? aliens????

viper

What?

When you see light of course it is beams of moving light.

All light is moving light waves, the colour you see depends on what colours of the specrum are reflected, and which are absorbed


It is impossible to send a laser into space, and for them to see it.

To get to the end of the known universe, actually lets use our galaxy, the milky way.

It would take a very very very long time. not just a matter of year, but qa matter of decades. And there is no possible way of them seeing somethign as small as a beam of light.

If there was an end to space, the light would just stop. It couldn't pass through it, because it is hitting something.

It could have bounced off of thing (dust particles, other planets, etc) but then it wouldn't be travelling in a straight line, which is the whole thing behind the experiment.

Light travels in straight line - if it stops going, then there is an end

It hitting things on the way make it go off in different directions, which screws it up.


Either way, there are no telescopes powerful enough to see how far the beam would go, because it is such a small beam.

For all we know, we may be the edge of the universe(s) *in saying that, I don't mean the known universe, I mean the entire enity of space* And the centre is way the fuck in the other direction then people are looking.

There is stuff inbetween, gas, dust, rock, ice etc.


But it is a vacuum, but that stuff is still in 'space'


And there are gravitational feilds, waves, rays etc


Which doesn't make it empty does it?

Ok, it's not empty. (I did say that once. )

All I'm saying is, if you took a part of space where there weren't any rocks or dust or waves or.... then it would still be space, no matter how small or big, it would still be space.

Who cares ?

I dunno

If there is an infinite amount of space but a finite amout of matter, well, it doesn't compute does it, the amount of matter in relation to the amount of space must also be infinitly small and well does that mean there is no matter?

I also read in New Scientist that Earth is a Spherical Geometry, which in small scales looks Euclidean (X, Y, Z all perpendicular). They think that space is the same but instead of being a sphere, it looks like a potato chip.

If there is an infinite amount of space, yes there is an infinite amount of matter


Doesn't mean that there is the same amount, but that there is no end to the amount is there


Should be written, if there is an infinite amount of space, then there is an infinite amount of matter, but amount of space>amount of matter

That's why Maths is stupid

If matter = space (both are infinite)
then how can matter < space

MATHS IS DUMB

No, infinite things don't mean they = each other


Two things can be infinite, but that doesn't mean to say that if you were to take one number of one of them, the other would equal that.

Just means, there is no end to them, mater being infinite is dependant on space beign infinite, if there was an end space (or a volume that it couldn't exceed) then matter would have a limit, and would no longer be infinite

really people... WHO CARE?!?!

Space is theoretically a temporal sphere. Which is just a posh word for its finite (only so much matter in it) but has no boundaries. Eg if you went in a straight line you'd eventually get back where you started.

Watch out for those quasars!

hmmmmmmmmm....ahhhhhhhhhh........ummmmmmmm.......mmmmmmmmm.....after long amounts of thinkin i would hav to say no.......space neva ends.....

p.s i only thought as long as it took me to write this

If you went in a straight line, it doesn't mean you will get back to where you started.


that is one theory, but is a crap one at best

dunno if there's an end, and actually I don't care

everything has an end, but not sure about universe

i would assume that space is one motherfucking huge sphere and youll propbably end where started, that is if there was the technology to do such a thing

maybe theres some sort of invisible wall that conects our dimension with another a dimension dogs walk people

lol i couldnt care well ive had my theory

there may be and their may not, its probably something humans will neva find out until about 1000000 of years when the earth is overtaken by AI!!!!!!!!!!!!

hey people..lets think .....if there is a beggining and an end for everything...dont u think that includes space........but were or what is the begginin of of space or the end????? weird..

*sittin with some smart appearance *
who told ya.. dat dariz some "end" fo everythin?

If there is an end to space, i reckon there's a brick wall around it, and if there is, I want to be the first to tag it. hehe
but think about it, scientists say that the Universe is everything, and the Universe is ever expanding. So therefore i propose a question: what is it expanding into?

More Space Pictures!!!!!!

where? :wtf:

End to space?...naw...
* DXtremz likes to think that space goes forever...or maybe its round......wouldnt wanna fall of the face of space...:\...cuz, where would you go then?

woo pretty pictures!!

maybe there is an end, but we haven't got the technology to reach it

well if there's an end to space, what about a beginning/end of time? when did time start? and what was before that? i think the reason why people havent figured all this out is because we can't understand something "going on forever". we're born and we die, we kno it, and we think about everything "starting" and "stopping", and our brains can fully understand infinity or "no end/no beginning". well, at least MY brain cant understand it, but they say I was dropped on my head as a child so hell, what do i kno?

People on earth, many years ago, thought our planet was flat, right? but it turned out to be round. Maybe the univers is round 2 but in stead of us being outside of the sphere, we're inside, sort of like a galaxy. And their wer many universes that are in sumthing even bigger, wich is in sumthing even bigger... that would mean that their's an infinity of space, but not of our univers... pretty complicated

Though, thinking about it, if you take the Earth, and you walk, and walk, and walk, and walk, and walk, you will never come to the end of the Earth and fall off. That's because you're covering 3D space in 2D directions. Maybe space somehow becomes a 4D torus or sphere, where you can only cover 3D movements, so you can never travel in that 4th direction to escape. But then... there IS another way to go off the Earth... even if there weren't, there would still be stuff there... or, more correctly, the absence of stuff... oh, forget it!

Does anyone here believe in God?? i do

Yeah sorta do. too confusing subject though but i do think theres something bigger than us out there somewhere

lol face it as far as we know there is no end to space...

or there may be...

you never know evrything has gotta end somewhen or somewhere. its prob just too far away for anyone to ever kow about or ever prove

Blah... My beliefs on:

God: I dont have any
Space: Its expanding, and then will start contracting.

When it finishes contracting... what will be around it?? 

This gives me headaches... leave it to the scientists

but if its expanding, and its bounces back in (contracts) would'nt that make time bounce?, like make time go backwards?

Well, the only explanation I've come to so far is that there's no end because it circles... but that's my own theory, as good/bad as any others. I just wish we'll be able to explore some part of our galaxy one day, it would be kinda cool to colonise planets and, who know, find other planets with strange lifeforms. Too bad it won't be in our life times though.

I have often wondered that myself. Also why is space always horizontal? What is down? or up?  Is there more planets we don't know about sitting only miles in our vertical axis? Are the UFOs really coming from a plant that sits 400,000 miles under us?

One more: do UFOs actually exist?

[]

i noticed no1 talked about the big bang theory. If you assume that the big bang theory is true, then u also assume that all matter was created during the bang and therefore there is a finite amount of matter. Space was also created during the bang and therefore, space would also be finite. However, assuming you believe in a higher being (god, allah, etc) that created the heavens and the earth, then you really wouldn't know because they are all beyond human comprehension accoring to the old testament. these are my views at least from a religious and scientific prespective

i think its a circle like earth with lots of clusters of planets like our galaxy and then eventually joins again and theres not just one sun but hundreds.

well f course there are hundreds of suns that pretty obvious but there not called suns there stars lol  our "sun"is just another star and here on earth we are lucky enough to have the living conditions that we do and there is most likely other planets just like ours we will just never find them because they are out of our reach and do not have the technology.....yet.

alien,not ufo's cause UFO just means their spaceship do exist well thats just wat i think and one day we will prolly look like them too       maybe

Well heres my opinion:

It all comes down to what you believe in; If there is a "beginning" to the universe, then I believe that you would reach a point in space where literally nothing exist, no time no space and no mass, because scientifically, the universe is contracting, so there must be an end, so, when you reach that point and (try) cross the border, you would:

a. Disintegrate at the border
b. Never make it there, and just fell a wall (), because humans are composed of enrgy/matter and to pass matter through nothing, is like walking into an impenetrable wall.

Now, if you dont believe in "The Big Bang", then I don't think that space will ever end, because it must be infinite if it doesn't have a beginning. And in that case...perhaps God might solve the puzzle?

If you don't understand one bit of this post, then don't worry, i'm pretty confused right now my self .

Okay heres my two cents...
Scientists currently have three main theories on the shape of the universe which will ultimately determine if there is an "end" to it.
It some wierd variable thingo (i forgot its name ) is <1 then the universe is closed something like a sphere. In this case the universe is finite.
If the variable = 1 the universe is flat... in this case the is no end to the universe instead you loopback or something i forget.
If the variable > 1 the universe is in this wierd camel hump shape... if you can imagine multiple camel humps joined together something like that. In this case the universe also has no "end"

I am not a theoretical physicist or anything so i am probably wrong or said something wrong here... but that's all i could remember.

edit: just remembered another thing.... to test this theory scientists want to measure the angles of a triangle. Heres an experiment you can try yourself.
Draw a triangle on a piece of paper (flat universe) suprise suprise 180 degrees
Draw a triangle on a sphere (finite/closed universe) more than 180 degress wow...
I think in the case of the wierd one angle is less than 180 degrees but i can't remember the exact reason why...

Now for those of you who are curious it isn't easy for scientists to measure the angles of the triangle for one simple reason. Get the sphere out again and draw the smallest possible triangle you can. That triangle is probably representative of the milky way in the whole universe. Now if you measure the angle its pretty close to 180 degrees. So scientists need a really big triangle to work out which case is true.

Also another side note if the universe is spherical... parallel lines do cross!!!! Imagine a globe... and now imagine to lines of latitude. These lines are "parallel" however, they meet at the poles...

All this stuff is interesting... but it also confuses the heck out of you

contracting, expanding, beginning, end.... these are all words that refer to things we can comprehend. Words that we use to try to make sense and try to understand....

When talking about the universe, there is something that scientists autmaticly do. They talk with basic human words but they use them to make theories which humans can't comprehend. There is not a single person who can understand and explain how big the universe is. We can only "imagine". That's because the human brain can't handle such complex stuff...

A nice example: Everybody knows what 3D is and can comprehend it. But there is also 4D, now imagine how that will "look". ("look", example of such a word which I talked about in the first paragraph. Actually "to look" means you can see something, and seeing means 3D, not 4D...)

And when we come to the universe-talk, everything is like that, we "say" it extracts/compresses. We can't comprehend that, because the universe is infinite, yet it contracts... So that should be impossible, yet it is possible (proven)...

The Big Bang (or something similar) has existed. Scientists say that everything comes from a single "something" (calling it "atom" would be wrong). This has been proven, yet we can't comprehend that or put it in words and describe it. We can only give a relative explaination and simplify it by doing that.

But by doing that, we also make mistakes on purpose. It is wrong to build further upon those "simple" explainations (with the included mistakes), and that is exactly what you're doing if you say things like "the big bang existed, so everything came from a single thing, so that means matter is finite"...

Also, another thing. Many people say that space itself contains nothing. Well that has been proven to be wrong. "Nothing" does contain something; there is something called "black matter", which is the opposite of matter. Again something we can't comprehend, but it does exist. So even if all the matter was contracted again (big bang-loop-theory), space would still exist and would be "filled" with black matter (or sometimes called anti-matter)...

Also don't forget that the laws of nature as we know them, don't exist in space as we know them. In space there are other laws. Laws which have to be yet discovered, or to put it in a better way: the big law has yet to be discovered. Because many laws have been discovered already. But many laws contradict other laws.

It's nice to talk about all this stuff, but you must not forget that it is just talking about very simplified things and thus you can't make assumptions and theories. We aren't scientists. We can only try to understand what those formulas means. Heck even scientists have often problems understanding their own laws.....

If you are interested in those things, I suggest to read a book from Stephen Hawkins (their is that dude again ). His string-theory (everything exists of "strings") is very very very complex and explains many strange things happening in the universe (black holes, worm-holes, relativity, mini-big-bangs, contracting, expanding, lack of time, butterfly-effect, etc.. etc..), but at the same time it can realy explain the basic laws of nature (from Einstein, Newton, etc...) on earth as well. And although it is very complex, it can put things realy simple by comparing it to strings of a violin...

I'm going to end this strange post I can talk about it for hours, but my English isn't good enough to do that. All I can say is that it is fasinating and fun to talk about it. But let the scientists do their job, and let us do ours: enjoying life and wondering how beautiful it can be (and how shitty it can be).....

You just reminded me of another thing cookie... the universe is not infinite! while there may be no "end" to the universe it actually has a finite "volume".

Also i remember another thing for the mathematicians out there to imagine this... if you imagine a mandelbrot set (the set of all points x+yi that do not diverge)

It has a finite area (clearly its volume is less than a binding rectangle you draw on it)

However it has an infinite perimeter since the mandelbrot set has infinite complexity. This could be an example of how the universe works... maybe i dunno....

hehe, indeed, I was reading your post:

I truely think space is a sphere.... don't ask me how it's possible, i'm still trying to figure that little detail out

I think some people in here are underestimating the human mind by saying that there are things we are unable to understand, just think we have evolved so much in so little time (hey +5000 years isn't that much after all). A few thousand years ago man would probarbly start worshipping a TV if it suddenly appeared in front of them.

And have you ever heard the one about those monkeys? well, just think about this, if monkeys kept on writing random words for a loooong time, one day they would eventually write the Bible, weird huh?

Space isn't flat.... who said it was? Of course there are planets under/above us, our own solar system isn't flat (not all planets move in perfect concentric circles.... some go up and down more than others....)

I stand corrected....

(btw energy=matter    E=MC^2)

errr, u just proved energy isn't matter, e=mc^2 means that, in terms of unit, energy = (kg*m^2)/s^2 even tho c is a constant, they are NOT the same ... i learned this in physics just now, itz like saying velocity=displacement (distance) becuz v=displacement/time, but we all know that isn't true (i hope)

i also quote http://www.geocities.com/thesciencefiles/emc2/emc2.html (from google)

quote:

---

Einstein's formula tells us the amount of energy this mass would be equivalent to, if it were all suddenly turned into energy. It says that to find the energy, you multiply the mass by the square of the speed of light, this number being 300,000,000 meters per second (a very large number)

---

quote:

---

To calculate the fraction of the energy in the Universe which is Dark Energy Manchester's Dr. Kyu-Hyun Chae combined the gravitational lens statistics with the latest results on the numbers and types of galaxies in the Universe made with optical telescopes. The result which emerged is that around two thirds of the Universe's energy appears to be Dark Energy.

The remaining third is made up of Dark Matter, whose form is presently unknown, and "ordinary" matter which makes up the stars and planets. For both of these forms of matter gravity acts as normal and attracts.

In contrast Dark Energy has long-range anti-gravity properties and now appears to be causing the expansion of the universe to accelerate, rather than slow down as would be expected if gravity was the dominant force. While astronomers have no idea about what Dark Energy might be, these new results add to their growing confidence that it is real.

hmm i dont really know what i think
i think that there isnt an end of space... it would be weird if you were in space with your spaceshuttle and flew as far as possible, but then you stop. you cant go further cause there is some kind of wall blockin' your way. that would be really weird.

but what IS there? i dunno..
i want to know too if there is something beyond space

sasquatch, I'm not gonna quote you (too much ), but illuzn already made some important comments... Although you learned that energy isn't exactly (mathematicaly) mass/matter (which is correct), it is the same in a sense that you can convert mass to energy and energy to mass (which was what I meant with "energy=matter", it wasn't a mathematicaly correct formula). That's a fundamental law. (at least in theory, we humans can't do it in practice (yet?) unfortunatly, because otherwise all energy problems in the world would be solved)

and "velocity=displacement": that is actually true. Whenever you have velocity you will have speed and therefore, you will have displacement. (Vice versa is a bit different: only when you have displacement and your speed is different, then you have velocity.)

Furthermore, you, without knowing it I think, actually quoted almost exactly Hubble's law (velocity=H x distance, where H is Hubble's constant). This defines the expantion rate of the universe and is a method to measure distant objects

space is forever expanding.... and theoretically will keep doing so until it loses momentum and begins to implode tbh, we wont know until it happens.... but as far as we are concerned, it just keeps on going....

Ill just say what i think i remember:

Space is forever expanding, so youll never reach the end.
But of cource there are many theories. And i guess well never know cuz its so fucking big.

So who knows...

Space must be infinite, because if it were to stop suddenly, there would have to be an infinite amount of matter after it

Space = absence of matter (sort of)

[EDIT]

This may not be true though because space isn't empty

i'm probably wrong, but thats wot i think

[/EDIT]

Or there could just be a place after space where the laws of time and space do not exist, matter can not exist, therefore nothings there...not even time...

Well I think that there is an end, in that we can't get past a certain point without going faster than the spped of light but if we could break that rule then we would be set. It's hard to explain, but the universe is moving apart so fast that there are some stars that we will never be able to see. If you wanna understand then read a new scientist from awhile back.

It could have bounced off of thing (dust particles, other planets, etc) but then it wouldn't be travelling in a straight line, which is the whole thing behind the experiment.

If there is an infinite amount of space but a finite amout of matter, well, it doesn't compute does it, the amount of matter in relation to the amount of space must also be infinitly small and well does that mean there is no matter?

I also read in New Scientist that Earth is a Spherical Geometry, which in small scales looks Euclidean (X, Y, Z all perpendicular). They think that space is the same but instead of being a sphere, it looks like a potato chip.

I think space could have an end to it, but if we ever came even close to finding it, god would just add on another good chunk of space. 

Anyways, unless theres a big planet out there where the  naked angels from south park live, i dont care about space.

If matter = space (both are infinite)
then how can matter < space

CHAPTER 2
SPACE AND TIME
Our present ideas about the motion of bodies date back to Galileo and Newton. Before them people believed
Aristotle, who said that the natural state of a body was to be at rest and that it moved only if driven by a force or
impulse. It followed that a heavy body should fall faster than a light one, because it would have a greater pull
toward the earth.
The Aristotelian tradition also held that one could work out all the laws that govern the universe by pure
thought: it was not necessary to check by observation. So no one until Galileo bothered to see whether bodies
of different weight did in fact fall at different speeds. It is said that Galileo demonstrated that Aristotle’s belief
was false by dropping weights from the leaning tower of Pisa. The story is almost certainly untrue, but Galileo
did do something equivalent: he rolled balls of different weights down a smooth slope. The situation is similar to
that of heavy bodies falling vertically, but it is easier to observe because the Speeds are smaller. Galileo’s
measurements indicated that each body increased its speed at the same rate, no matter what its weight. For
example, if you let go of a ball on a slope that drops by one meter for every ten meters you go along, the ball
will be traveling down the slope at a speed of about one meter per second after one second, two meters per
second after two seconds, and so on, however heavy the ball. Of course a lead weight would fall faster than a
feather, but that is only because a feather is slowed down by air resistance. If one drops two bodies that don’t
have much air resistance, such as two different lead weights, they fall at the same rate. On the moon, where
there is no air to slow things down, the astronaut David R. Scott performed the feather and lead weight
experiment and found that indeed they did hit the ground at the same time.
Galileo’s measurements were used by Newton as the basis of his laws of motion. In Galileo’s experiments, as a
body rolled down the slope it was always acted on by the same force (its weight), and the effect was to make it
constantly speed up. This showed that the real effect of a force is always to change the speed of a body, rather
than just to set it moving, as was previously thought. It also meant that whenever a body is not acted on by any
force, it will keep on moving in a straight line at the same speed. This idea was first stated explicitly in Newton’s
Principia Mathematica, published in 1687, and is known as Newton’s first law. What happens to a body when a
force does act on it is given by Newton’s second law. This states that the body will accelerate, or change its
speed, at a rate that is proportional to the force. (For example, the acceleration is twice as great if the force is
twice as great.) The acceleration is also smaller the greater the mass (or quantity of matter) of the body. (The
same force acting on a body of twice the mass will produce half the acceleration.) A familiar example is
provided by a car: the more powerful the engine, the greater the acceleration, but the heavier the car, the
smaller the acceleration for the same engine. In addition to his laws of motion, Newton discovered a law to
describe the force of gravity, which states that every body attracts every other body with a force that is
proportional to the mass of each body. Thus the force between two bodies would be twice as strong if one of
the bodies (say, body A) had its mass doubled. This is what you might expect because one could think of the
new body A as being made of two bodies with the original mass. Each would attract body B with the original
force. Thus the total force between A and B would be twice the original force. And if, say, one of the bodies had
twice the mass, and the other had three times the mass, then the force would be six times as strong. One can
now see why all bodies fall at the same rate: a body of twice the weight will have twice the force of gravity
pulling it down, but it will also have twice the mass. According to Newton’s second law, these two effects will
exactly cancel each other, so the acceleration will be the same in all cases.
Newton’s law of gravity also tells us that the farther apart the bodies, the smaller the force. Newton’s law of
gravity says that the gravitational attraction of a star is exactly one quarter that of a similar star at half the
distance. This law predicts the orbits of the earth, the moon, and the planets with great accuracy. If the law
were that the gravitational attraction of a star went down faster or increased more rapidly with distance, the
orbits of the planets would not be elliptical, they would either spiral in to the sun or escape from the sun.
The big difference between the ideas of Aristotle and those of Galileo and Newton is that Aristotle believed in a
preferred state of rest, which any body would take up if it were not driven by some force Or impulse. In
particular, he thought that the earth was at rest. But it follows from Newton’s laws that there is no unique

the universe's first 1/1,000 of a nanosecond.
1) The big bang creates equal amounts of matter and antimatter.
2) One of every billion antimatter particles changes into a particle of matter.
3) Matter and antimatter annihilate each other.
4) The result: Antimatter destroys 99.9999999 percent of the matter in the universe.
