Default What is physics, the physical world, and reality?

Patrick Reany:

No. But the "being alive" aspect of animate matter is superfluous for
two reasons in physics: The first is that when physics models animate
matter, it will model it as collections of inanimate parts or systems
anyway (levers, pullies, potential differences, ion transport,
pressures, forces, heat flow, etc), and second, basic reasearch in
physics does not require animate objects, at least it has not been the
case in a long time.


Not necessarily. The physics required for the condition we call
"being alive" might place constraints on the variety of universes
that could have been possible. The ability of the universe to support
living things precludes universes which have only one or two spatial
dimensions, for example.
