I don’t know, I’m not a physicist. Don’t they have vacuum energy and virtual particles and other stuff that makes even empty space full of information? ETA: what’s empty space? A near-zero value of all relevant fields? But if fields can be measured to the same precision regardless of magnitude (?) then don’t you get the same amount of information unless the fields are actually a constant zero? I don’t understand physics, this may well be completely wrong.
Anyway, I expect the lack of phenomena important to brains in empty space (no ordinary matter and energy, atoms, chemistry) allows the compression of that. But can you simulate a typical physical system using significantly less matter or energy? (Or time?) Can you simulate the human brain or body?

Not so much as near black holes. Just look at their respective entropies.
FWIW, I expect that the human brain will prove to be highly compressible with advanced molecular nanotechnology.
Do you mean the compressibility of a single human brain in isolation, or the compressibility of an individual human brain given that at least one other human brain has already been stored (or is expected to be available during restoration), or both? I expect the data storage requirements of the latter to be orders of magnitude smaller than the former.
Why would “physics” be incompressible? Most of the universe is empty space, no?

I was talking about the compressibility of a single human brain in isolation.
