What is physical possibility?
Something is a physical possibility if it is allowed by some set of consistent natural laws. Something is metaphysically possible if it is allowed in some possible world. Physical possibilities are a subset of metaphysical possibilities which, in turn, are a subset of logical possibilities.
Is everything that is logically possible also physically possible?
Everything that is physically possible is logically possible, but the converse isn’t true. There is no magic in any physically possible world, because the existence of magic would violate the law of conservation of energy.
What is physical possibility example?
