Let's imagine I have a vacuum chamber bisected by a wall of glass (2 coaxial chambers), and I conduct a "light speed" experiment in which light is introduced into the end of one chamber and shined through the opposite end of the other chamber. c in the first chamber is 299,792,458 m/s and c in the second chamber is 299,792,458 m/s; however, c through the glass is (arbitrarily) 214,137,470 m/s (5/7 c in a vacuum).

The photons impart a very small amount of energy to the glass as they are slowed; however, they accelerate to their original speed upon exiting the glass. How is this possible? Whence cometh the energy to accelerate those photons?

I realize the accelerated mass is going to be infinitesimal, and that the rate of acceleration is going to be near infinity, but the energy still has to have come from somewhere.

One thing that bothers me is the so called "time paradox". For example, what if we go back in time and accidentally kill our grandfather, thus ensuring that we were never born, so how could we go back in time then? One way out of this type of paradox is the realization of the "many worlds" hypothesis but where is the proof for the "many[infinite] universes"?

According to Einstein’s famous equation, E = mc2, matter and energy are interchangeable. So far, we have converted matter into energy through fission and fusion.

Beyond trivial, quantum level interactions, has anyone found a way to create matter out of energy?

I have been very curious about this for a year or two now, and have been wondering if sound can travel through a vacuum. More specifically whether sound in space ie. an explosion could be heard on a ship with an atmosphere. Yea I know it's basic physics, it's just been a long time.

Would the jumping simultaneously in one spot make the earth's rotation just a split second faster since no one was touching the ground> Or would it make it slower since we would all come down and stomp at the same time as well? Its a physics question, and I learned it in college physics, but I have since forgotten... thoughts? p=mv

its almost the fourth of july, and i have a few roman candles, bottle rockets, a few m80s, and fircrackers. i wanna somehow make a badass explosion by maybe combining these and/or adding something to make the biggest explosing i can. inoe, im f$@&(^@ crazy.

I recently learned about string theory in class, and i was just wondering about a thing or two. If the so-called "strings" are massless, then where do they get the energy to vibrate, stretch, and expand in space? i thought e=mc^2?

I think that is if it goes up it has to get back down, isn't it dangerous when is coming back.
