some ways the macroscopic stuff might evolve is flat out impossible.
Like it violates energy conservation or something.
But most of the things we don't expect to happen
are not flat out impossible in that sense.
I mean there's I'm sitting in a skyscraper at the moment.
Is it flat out impossible that in the next ten seconds it could collapse into a swirling mass of dust that reassembles itself into a massive bust to Donald Trump?
Um no, it's not flat out impossible.
Um the the bust would have the s you choose it right it'd have the same energy as the rest of the building.
There's no other flat conservation law being violated if we pretend everything's classical.
There'll be some.
ludicrous by honest I i in microphysical terms, ludicrously implausible.
dynamics that gives rise to it.
Um but it's not flat rule out.
Um
So turn that round, there's some choice of initial conditions.
or choice of probability measure over initial conditions such that the skyscraper turning into a bust of Donald Trump is certain.
Just just take all the um you know, j just uh take all of the microstates that are compatible with their happening and evolve evolve that distribution back in time to the beginning of time.
Right.
Again, but continuing to pretend things aren't quantum.
Evolve it back to the Big Bang, you'll get a
