100 years later in physics: The chasm between Relativity and Quantum has been going on for 100 years- an abyss- with no sign of resolution to this day. Both theories have withstood all attempts at falsification, and have given us industrial evidence they are true: Nuclear Energy, and the Computer. Alongside them stands Thermodynamics, whose loop was closed via Carnot, Maxwell, Gibbs, Boltzmann, and Nernst, just at the same time Relativity and Quantum were discovered. The Fate of the Universe is according to the three, at present, I think: !. Relativity allows several solutions. 2. Quantum does not know how many solutions there are are. 3. Thermodynamics allows one solution: that eventually ALL the energy in the Universe will dissipate, trending toward complete scatter.

but it may be narrowing.... String Theory offers a hope..... and yes ... all the energy in the universe will eventually turn to entropy....

I would like to think so. The string theorists themselves, though, last I heard, were saying it would take another 50 years. They got math problems, even as smart as they are. Ten and 11-dimensional geometry, and such. No place for simplicity.
