The whole point of physics is to gain confidence in where the universe is going.

Open in the sense of depending on interpretation and thus inherently unanswerable, or open in the sense of subject to ongoing research which stands a reasonable chance of answering it before the insects take over ?bhobba said:The probabilities thus obtained would be meaningless.
Its an open question if the state of the universe is a valid concept.

friend said:What would it take to write the universal wave function? What do we need t write any wave function? we need the starting state, and then what...?
I choose to interpret it as meaningful.bhobba said:A model eg

Some question if such are meaningful.
stevmg said:According to William Thomson (Lord Kelvin) who predates Planck et al, entropy is always increasing implying that the total energy level will asymptotically approach some unspecified universal mean of total neutrality in some very distant future.
bhobba said:Its entropy that increases - chaos is coming - energy remains the same.
friend said:Has entropy been proven on first principles of QM
friend said:Has entropy been proven on first principles of QM or GR?
friend said:Actually, I meant: Can the 2nd law of thermodynamics be derived from first principles?
