Convert matter to energy and back into matter

Click For Summary
SUMMARY

The discussion centers on the feasibility of converting matter to energy and back to matter without harm. It establishes that matter and energy are fundamentally different, and the concept of matter is often ill-defined. The annihilation of an electron and positron, resulting in two photons, illustrates that while rest mass can change, the total energy and mass remain constant. This highlights the complexities involved in matter-energy conversion.

PREREQUISITES
  • Understanding of Einstein's mass-energy equivalence principle

Do u think it is possible to convert matter to energy and back into matter the same way without harm?

this could be a good way of travel

Not exactly, no. They are two quite different things. The term "matter" has always been ill-defined and therefore one can't say if the amount has changed when it can't even be quantified. The amount of energy present at anytime is always constant. What can be done is to change the form of matter that is present from one in which the rest mass of particles is non-zero to that when one form in which the rest mass of some particles is zero. E.g. an electron and positron can anihilate each other producing two photons. The electron and positron each have a finite rest mass while each photon has zero rest mass. However the total energy and the total mass is non-zero and the same after the anihilation as before.
