- I am very interested to know the following:
-
- As per the Special Theory of Relativity (1905), E = m*c**2, which
- means the energy and mass are the same thing, i.e. two different
- expressions for the same thing. Some people measure it by grams,
- while some measure it by Joules.
-
- Now, if it is indeed true, why is that sunrays or for that matter
- any other energy such as heat does not by itself convert into mass?
- That is while I am shaving in front of the mirror, why is that the
- light emnating from the lamp does not get converted into mass?
-
- Similarly, why is that the keyboard I am typing on does not decide
- to convert itself into energy (by itself - after all they are the
- two different expressions for the same thing...).
-
- What conditions must be fulfilled for the conversion to occur from
- one form to the other? To avoid any complications, let us assume that
- the universe consists of one Hydrogen atom and the rest is space.
-
- This is a serious question, so please answer it in detail. I appreciate
- your responses in advance.
