Will the LHC be able to test String Theory? (Synopsis)

A few weeks ago, Amanda Peet gave a public lecture that we live-blogged here. In the Q&A part after the talk, she made a statement that I sort of glossed over: that the LHC was able to verify some of the predictions of String Theory. In my head, I thought, "yeah, all the predictions that the Standard Model itself made, and nothing more." And I let it go.

But maybe it's time to ask that question for real: will the LHC be able to test String Theory? And if so, how? This is a question that -- quite honestly -- was a little beyond what I knew how to do, so I called in an expert from among our contributors: Sabine Hossenfelder.

Here's her answer, and the amazing story of whether the LHC will be able to test String Theory!

Another great article by Sabine! Wish she was at Perimeter talking more on LQG instead of Lego-land lecture. Loop Quntum Gravity.... which for reasons unknown to me, is sadly never covered on this blog.

Love the Sabine articles and also vote for something on LQG. Ethan has given more time to MOND and he hates MOND.

Considering that I get much of my knowledge of theoretical physics from this blog, and the fact that I really don't know very much about LQG, I would also not mind seeing an article or two about it. Of course, that just may not be Ethan's area of expertise and he may not have a guest columnist willing to take on such an article, so I fully understand if such an article doesn't appear.

The trick with getting Ethan to write about a particular subject is to approach it from another angle.
That angle would be his significant other Jamie . If not for her, we may not even have articles/thoughts from Ethan on String Theory here on his Blog at all.

So if you want a post from Ethan on LQG, I would appeal to the higher authority.

Thank you Sabine for a logical look at string theory. I think SUSY is running out of places to hide!
PS let's have a LQG article ;-)

sabine, what is your views on LQG?
