Is the quotient pressure of Space and density always equal =C^2?

Answer 1

A safe answer would be "no."

I am sorry to say that after studying your question I am not able to make sense of it. I believe you are confused about the meaning of several terms.

The term C^2 occurs in the famous mass-to-energy equation "E=MC^2" because the equation is a special case of the classical equation that expresses the kinetic energy of a moving object; that is, "Ek=1/2MV^2" where...

Ek == kinetic energy

M == mass

and

V == velocity

The poor old worn-out formula "E=MC^2" is really an imponderable that expresses a semi-rational relationship that cannot be expressed in practical terms using such quantities as density and pressure.

Your question, however, suggests intelligent inquiry, and you should not give up. Ask your teacher for advice about these terms.

Good luck!
