I don't think anything can go faster than the speed of light squared

I don't think an infinite amount of time has passed

the universe is expanding at infinity [any units of measurement] per second

- "The speed of light squared" has units meters^{2} per second^{2}. It is not a velocity.

You can't square time. Velocity is displacement over time. Not just distance by itself. Therein lies the stupidity of Einstein's so called equation E =MC squared.

If you want to continue posting in the main sections of this forum you need to learn some basic science.

The speed of light squared is the amount of energy you get when you push two sub-atomic particles together. That's how the sun makes its light and energy.

The sub-atomic particles ...create 2 neutrons, plus heat and light as a bi-product.

It seems that you are talking about Einstein's iconic E=MC^{2}.Interestingly, it's not the mass of the starting particles that represents this energy, or the mass of the ending particles, but the difference between these figures (the "missing mass") that represent the energy released.

The atomic reaction* with the greatest "missing mass" is to take 4 Hydrogen atoms (ie 4 protons + 4 electrons) to produce 1 Helium atom (ie 2 protons + 2 neutrons + 2 electrons) plus some neutrinos and gamma rays (representing about 0.1% missing mass).

Some variant of this reaction is what heats the Sun, and powers Hydrogen bombs.Neutrons by themselves are unstable, and decay in about 12 minutes. It requires a proton to stabilize the neutron.See: ...sorry, you cannot view external links. To see them, please REGISTER or LOGIN

To square something means to turn it from a straight line into a square with 4 sides and then to measure the area inside the square.

If you studied basic high-school physics, you would be aware that the units of Energy are Mass times Velocity^{2}.You leaned it in the form of kinetic energy: E=1/2 mv^{2}What they didn't mention in basic physics is that m is the relativistic mass, and it isn't a constant - although that's not really noticeable until the object is traveling at close to the speed of light.So if you have a proton in the LHC, it's velocity is almost the speed of light (c), so you could say it's kinetic energy is effectively E=1/2 mc^{2}, so basic high-school physics can get you half way to Einstein's iconic formula.What Einstein showed is that if you slow down an object to stationary, it still represents an enormous amount of energy, which is demonstrated in antimatter annihilation.When Einstein added up all the components of energy (including kinetic energy), he arrived at E=mc^{2}It's a brave man who would call Einstein's work "stupid" (unless you are Einstein - he felt that about his gravitational constant, which now appears not so stupid, after all!).

To see the stupidity of E=MC squared, just use both kilometres per hour and miles per hour in your calculations and you will get two different answers for the same equation.

It uses meters for Length, seconds for Time, kilogram for Mass and Joules for Energy.See: ...sorry, you cannot view external links. To see them, please REGISTER or LOGIN

Consider infinity in the reverse, instead of how big, how small, how often can you cut whatever in half, and will there be a point you can cut it in half no more?
