This is not true. Stars burn out, planets disappear, and particles are theorized to lose all of their energy somewhere down the line (+

You sure about that? I exist, though I've never seen anyone create another me. Not that it is eternally impossible, but it currently is.

Any discovery, and there have been some in the past, that is or approaches perpetual motion will be rejected because it is not economical; it does not result in economic dependency.

I agree that it is not economical in an energy sense. You're always losing more than you spend. No investor would bet on that.
