Well ..... its basicallay proved by einsteins rest mass to velovcity mass equation
m = (m0) / (1-v^2/c^2)^1/2
Where m is you mass at velocity v
m0 is your mass at rest (that zero is a subscript
)
c is the velocity of light
Thus as you velocity approaches the speed of light ... your mass becomes higher. You cant exceed the velocity of light cause well .... root of negative numbers are imaginary
So for any given case
v^2/c^2 <= 1
v <= c

Remember this example. If there are 2 identical twins. You tell one to stand on a planet and you tell the other to go at the speed of light till a star and comeback. If he comes back after one year by his his time ... his brother may have aged about 50 years ...
I dont have the mathematical proof for this, but this is what happens.

Well ...
NO YOU DONT
As i have already explained in Einsteins equation, as you velocity increases, your mass does too but this is only possiple as long as,
v < c
Once you reach the velocity of light, all your mass (the one that you had and the one that you had gained due to your velocity) gets converted into pure energy. No mass can exist at the velocity of light well except for protons is light (according to De Broglies Hypothesis / Dual Nature Of Light) [quanta (packets of energy; they dont have mass
) are a different story. They are energy]
And btw, speed of light isnt the fastest thing. Its been broken .... about 10 years back
Well a few british scientists took a dark tube, made a small hole, let light enter and reflected it in one direction. Then from behind it the let a laser loose. They wanted to find the velocity of the laser under different laser. Note that this is a special type of laser. They noticed that under certain conditions the particles of the laser reached before that of light.

Underlord, thats not true. I could explain if anyone wants to know ...
When a star burns normally there are two forces acting upon it, its high gravitational force acting inward (high because ..... it holds the whole planetary system together dont they) and the force due to contunious nuclear fusion (which acts outward)
It is the magnitude at of these forces that determines the size of the star at any instant. It remains like this for say a few kazillon years
Then eventually its low on fuel (hydrogen), it swells up for a few millenia (short time for starts pfft
) cause the outward force due to nuclear fusion decreases due to a lower combustion rate. Then it runs out of hydrogen and its screwed cause it still has the same gravitational force but the outward force is zero. Thus it shrinks but as it does, its mass it still constant but its volume
tends to zero
Density = Mass / Volume
Thus it has infinite density and thus infinite gravitational force. Thus not even light can excape it

O.o
Their mass is the mass of the helium remaining from nuclear combustion !!! The gravitational force comes from their negligible volume
and high mass.
They think ??? Who think ?? Do you mean i think

Wasnt that a huge controversy !!! Stephen Hawking was wrong and no one figured it out for what ... 40 odd years ??
There was this one guy in the atomic research center here (where i live) and he was saying all along that what stephen hawking said was wrong. Black holes need to emit stuff as well, but people asked him how dare he question stephen hawking and stuff .... for about 30-35 years he was tormented ..... finally when stephen hawking accepted his mistake this guy was vindicated
