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

You wouldn't know and the traveling would be very very boring, because you wont see much... Although there is a lot in space, it all is very distant appart, it's not like in StartTrek where you push a button and 5 minutes later you come to a new solarsystem... Also, the human can't even leave his own galaxy in his lifespan, you would've already died of extreme old age before you even come close to the "edge" of our galaxy (which is only a very very very very very ... very small dot in the known universe).... The closest galaxy (Andromeda Galaxy) is 2.9 million light years away from the sun. (how do we know this:
see this very nice explaination)
(for those who do not know: a light year is not a time refference but a distance refference like kilometers or miles... 1 light year = the distance that light can travel in 1 year, so if humans could travel with the speed of light, it would take 2.9 million years to reach our neighbour galaxy)
To give a very SMALL idea of how big the universe is:
* We all know our
solarsystem
* Our galaxy (of which we can see a part of it, known as the
Milky Way in the nightsky) consists of billions of such solarsystems
* Our closest neighbour galaxy is 2.9 million light years away called
Andromeda Galaxy (travelling at the speed of light, it would take 2.9 million years to reach it.)
* There can be thousands of galaxies in one galaxy-cluster (all distant appart in terms of million of lightyears). Our galaxy-cluster, named
The Local Group, is however very very very poor and has only two large spiral galaxies, one small spiral galaxy, two ellipticals galaxies, 13 irregulars, and 14 dwarf ellipticals.
* Clusters also group together on their part to form
superclusters. Again there are billions and billions of such superclusters...

(note the "dots" you'll see in most part of the "travel sequences" are not stars!, they are galaxies which consist billions of stars)
