Like him. But he makes so many speculations.

Time machines? There's nothing in physics that I know of that indicates that they are possible. It is not just an engineering problem, Michio. It is a physics problem in the sense of rewriting all the physics textbooks.

Worm holes? Even if they exist subatomically, using them for transport is another one of those new physics textbooks things. Plus, those who claim the physics says yes admit that we're talking truly talking about gigantic energy requirements to stabilize one, which would likely destabilize if a mass fell in. I would not volunteer to be first, if ever.
