A thing that is viable in one set of laws of physics will not necessarily be viable in a new set of laws of physics.

The viability of a thing is less about its intrinsic properties in a vacuum, and more about the laws of physics of the environment it's in.

When the laws of physics change, everything changes.

Things we took for granted in the other physics suddenly become non-viable.

And things we assumed were impossible suddenly become gloriously, surprisingly viable.

This is a hard idea to wrap your head around. It's so foreign.

It's like me saying "OK, so now objects will fall up."

You'll think you get it, but it won't stick in your brain until many interactions with it, because it's just so fundamentally different.

It changes absolutely everything.
