With nuclear physics, the answer is a definate YES!
Please. The Big Bang has never, EVER, been recreated. That is because even the smallest sub-atomic particle is in fact mass that must have an origin--something cannot come from nothing, IOW. Mass can be turned into energy, but not the other way around.
PetiteMericco, I appologize for the long delay.
You actually asked a very valid questions and it got me thinking.
We all know that E=MC2 and the Atomic Bomb is a very dramatic example of what happens when you convert mass into energy.
We also know that M = E/C2, so that energy can be conveted into mass.
But you asked an outstanding question, and I have been researching this subject.
What experiment that has been performed, can demonstrate converting energy into mass?
Each and every reply on this topic is read by me. Most replied are rather dumb, but sometimes I read something like yours that gets me thinking.
Outstanding questions!
