Sure it can. Ghost hunters use thermal vision and thermometers to look for ghosts.
But, since there is no such thing ghosts, they have yet to come up with any scientific proof.
I wasn’t talking about ghosts. Godel’s theorems prove that either the universe is infinite, or it is finite and infinity lies outside the universe (as theists maintain). And seeing that virtually everything we have learned about the universe suggests that it is finite, theists are on much more solid ground than philosophical naturalists when they claim a spiritual creator from outside the physical universe created the same.
