First, I'd like to ask the question, why is c (the speed of light) squared in "e = mcÂ˛"?

I couldn't find it anywhere online, so I tried to prove it to myself, and I ended coming up with this theory.

So my theory is based on the following information (this is the domain):

1. Space is unlimited

2. The universe is limited, but expanding

3. The universe is inside space

From these statements, we can say the universe is expanding by the speed of light, because light is being emmited through space, and light is the fastest thing we have in our universe. Since we now know the universe is expanding at the speed of light, and since we are inside the universe, then we are expanding at the speed of light. Since everything is expanding by the speed of light, it would seem as though nothing is expanding to someone inside the universe, because everything is relative.

Here's a fun sorta way to show this. Take a sponge, cut it in half on the thin side,don'tcut it all the way so that it is two pieces, but rather cut it in a way that you can see the center of the sponge. Now take a permanent marker and mark the sponge in the center. Take a bowl of water, and place the sponge in the water. As the sponge expands the dot in the middle expands as well. The dot is representing an object in the universe, the sponge is representing the universe, and the water is representing space.

We now know that everything is expanding at the speed of light from an outside of universe view. But then we are moving, so it is more than the speed of light... it is the speed of light, plus the distance one is moving when compared to the universe (if you walk one foot, it's not one foot... it's one foot plus the distance the earth has spinned, plus the distance the earth has revolved.. and so on...). Based on this, we can say that the speed of light relatively is going at the speed of light squared from an outside the universe perspective. Since everything is moving at the speed of light, then the speed of light itself must be moving at the speed of light times the speed of light.

This explains why c in e = mcÂ˛ is squared. For mass to become energy it must be going at the speed of light squared from an outside of universe view. I think the energy we talk about is not from a relative perspective (inside the universe perspective), but rather it is from an outside the universe perspective. So mass going at the the speed of light squared becomes energy.

Now, at what point can we go at exactly the speed of light From an outside the universe point of view? We can go at the speed of light from an outside of universe point of view when we are at 0 degrees kelvin. At 0 degrees kelvin nothing is moving relative, but the universe is still expanding. We are freezing time by going at 0 degrees kelvin.

When we go lower than absolute zero, we are reversing time (in theory). Now the universe would be expanding while the mass would be shrinking in comparison to everything else from an outside the universe point of view.

I am not sure what would happen if we are going faster than the speed of light squared...

Please criticize, but please don't flame.

Btw I know that Einstein based E = mcÂ˛ off some other equations, mainly being the equation of force. But maybe the force equation is also from an outside of the universe point of view.
