The last sequence of posts on Quantum Contradictions 1 - 20 gives examples of the crisis in modern physics recently described by the Perimeter Institute Director Neil Turok as follows:
- Theoretical physics is at a crossroads right now…In a sense we’ve entered a very deep crisis.
- You may have heard of some of these models…There’ve been grand unified models, there’ve been super-symmetric models, super-string models, loop quantum gravity models… Well, nature turns out to be simpler than all of these models.
- If you ask most theorists working on particle physics, they’re in a state of confusion.
- The extensions of the standard model, like grand unified theories, they were supposed to simplify it. But in fact they made it more complicated.
- The number of parameters in the standard model is about 18. The number in grand unified theories is typically 100. In super-symmetric theories, the minimum is 120. And as you may have heard, string theory seems to predict 10 to the power of 1,000 different possible laws of physics. It’s called the multiverse.
- It’s the ultimate catastrophe: that theoretical physics has led to this crazy situation where the physicists are utterly confused and seem not to have any predictions at all.
- We have to get people to try to find the new principles that will explain the simplicity.
