...quantum mechanics—the physics of our world—requires that you hold such pedestrian complaints in abeyance.
When I give this talk to a physics audience, I remove the quotes from my 'Theorem'.
The bottom line is that time travel is allowed by the laws of physics.
Physics grapples with the largest questions the universe presents. 'Where did the totality of reality come from?' 'Did time have a beginning?'
Even when I wasn't doing much 'science for the public' stuff, I found that four or five hours of intense work in physics was all my brain could take on a given day.
I think individuals are enormously surprised by the progress. When you look around the world, it's a very rich but complex place. When you understand the physics behind it, you understand it's a few simple laws ... if these cutting-edge ideas are correct.
