The problem that large extra dimensions just might solve is called the hierarchy problem, and it’s one of the nastiest outstanding problems in modern physics.

To test it, I want you to imagine rolling up a piece of paper into a tight cylinder. Or, if you happen to be near a source of paper, doing it in real life. The analogy works either way.

New mathematical research reveals string theory and hidden dimensions might be inevitable features of our universe

So we did that. And we found nothing. So far, with all of our experiments around the world, we find no evidence of missing momentum, and no signs of towers of gravitons slipping away into hidden dimensions.

I always say that one of the things that separates real science from pseudoscience is that while in both you’re allowed to say whatever crazy idea pops into your mind, in real science you’re obligated to take that idea seriously.

A simpler solution?

The geometry of space, the setting in which physical laws operate, may hold clues to some of the biggest unanswered questions in fundamental physics. The underlying structure of spacetime itself could...
