Does the sponteanous mass increase with increased relativistic velocity violate 2nd Thermodynamic Law?

Answer 1

Velocity is relative. There is no mass increase locally, nor does the local length change in the direction of translation (and Terrell rotation!) or time locally slow. It is all a point-of-view effect of external inertial observers. Within the closed system thermodynamics will balance both locally and for external inertial observers

General Relativity lacks global conservation laws. It is difficult to build a useful device on the scale of lightyears.

Answer 2

That's easy! Absolutely NOTHING is able to violate the second law of thermodynamics -- ever. Any apparent violation is just that -- apparent! For example, spontaneous mass increase at relativistic velocity is only apparent mass increase. What is meant by "increased mass up to the level of infinity" is really only increased resistance to further acceleration up to the level of infinity. In other words, at the speed of light, mass is infinitely resistant to any further acceleration, which appears to us as an increase in mass.

Answer 3

I must take gentle issue with Mr nickname. While it doesn't affect your answer, which is still that the second law is not violated (although things get a little weird around black holes) I must insist that the mass increase due to relativistic speed is real and not apparent.

Answer 4

I don't see why it should; the mass increase has nothing to do with extracting work from the system, heat transfer or entropy increases.
