Only in universe with 5 dimensions. Shouldn't string theory be given up on at this point? This theory has existed for over 50 years and hasn't produced any results. Even the predictions made by it such as e.g. supersymmetry have not been confirmed despite searching for them at particle colliders.
The issue isn't string theory yes or no (there are reasons physicists went this way and other alternatives aren't so much better), but the difficulty in getting data and testable predictions. It's very likely the most effective way to help particle physics is getting way more data at high energies, not a new theory.
As I understand it, it's still our best candidate for a unified theory of everything. Not for lack of effort in researching alternatives, either.
It has produced some good math though. That's something.
At what opportunity cost?
Low. It's too expensive to send all of humanity across the stars at present.
If you want to bash badly-spent potential look at people doing cutting edge ad research and optimization, or HFT. This is at least good base research that others can build on.

100% unknown. That's always the problem with science and why political control and direction always backfires and is stupid.
Has anti string theory propaganda taken over HN? Sabine Hossenfelder succeeded?
Anyone who is anti string theory actually qualified to make statements saying string theory is wrong or not worth more investment from researchers?
Are these anti string theory posts on HN mostly just laymen hearing how string theory can’t be tested and we wasted a lot of resources on it so it needs to be repeated on every string theory post here?
Susskind himself said its dead in the water. We dont live in an anti de-Sitter space, the basis of string theory.
