string theory lied to us and now science communication is hard

not a physicist but this video by Angela Collier is a fun watch: “string theory lied to us and now science communication is hard. ▶ this video

Exactly. Consistently untestable and unfalsifiable claims for decades has to be seriously questioned at some point, and I think we're well beyond that point. This is especially true for string theory. I'm particularly fond of how Angela Collier laid out the timeline of string theory in her video on it[0] as well as the consequences that science communication is now facing as a result.

I’ve found this explainer by Angela Collier super helpful in understanding the current state of string theory. ▶ this video I was a gigantic pop science fan and read The Elegant Universe when I was approximately 13 and am excited it’s still being read even if it’s not necessarily true about our universe. It’s got the inspiration and excitement part that’s all I really needed as a kid.

Collier has a video on the history of string theory as a narrative and how it kinda tainted the public perception of high energy/particle physics: "String theory lied to us and now science communication is hard" ▶ this video

For those that have the time and interest, Angela Collier is a somewhat newer science communicator, and covers everything described in this reply (and more) at ▶ this video . I don't have the knowledge needed to criticize or defend Dr. Collier's arguments, but Woit linked to her video at link , so he at least seems to appreciate it.

I just wanted to second this recommendation - while the video is nearly an hour long, it feels much shorter and is well worth watching: ▶ this video

Agree but very much with your caveat. If you study the mathematics of some sort of abstract structure you are doing research in pure maths. That is a worthy and completely legitimate pursuit and a ton of stuff started life as pure abstract mathematical research and ended up having real-world benefits way down the line that noone could have forseen.[1] If on the other hand you say that abstract structure is a fundamental building block of the universe and, say, unifies the standard model with gravity etc but actually your theory isn't explaining anything observable I would say that isn't theoretical physics[2] but is just "making shit up". So far string theory has failed to produce any sort of verifiable prediction[3], so I just don't see how it's physics (you could say "yet" perhaps). I enjoyed the video "String Theory Lied to Us and Now Science Communication is Hard"[4] by Angela Collier, who is a computational astrophysicist[5], because it gives a sense for how these things impact other physicists and the popular perception of science. [1] And Ed Witten for example is without doubt a very impressive mathematician - he won the Fields medal. [2] Which is the science of matter, energy, space, time etc all the stuff which makes up the natural world. [3] In particular, the one that has been tried is supersymmetry and the LHC, as I understand it as a non-physicist, brought about an experimental result that called supersymmetric extensions of the standard model into serious doubt

This [1] is a fantastic refutation of string theory in that the string theorists have taken more than their fair share of research dollars and public consciousness and that it's time for other branches of physics to get the funding. With limited resources, if you don't context switch, you starve everything else. [1] ▶ this video

I'm far outside of these social circles nowadays, but I stumbled across this youtube video of a phd candidate talking about string theory recently ( ▶ this video ), and it seemed to imply that the pendulum in those social circles is swinging back again.

Carroll's episode is worth listening to, not least for it's exceptionally clear exposition of the current physics consensus around QM, qft, standard model, etc., and how they are related, but the point you specifically mention is a weak spot for me. For one thing he hardly mentions the epic failure of string theory to make good on its initial promises nor the murky waters of anthropic claims and metaphysical notions of beauty, etc., used to keep it suspended like Wile E Coyote after running off the cliff of empirical support. As non-crackpot physics profs and postgrads (e.g. [1], [2]) have pointed out, this has not engendered public trust and is a key ingredient in whatever "crisis" the discipline is undergoing. Not that Carroll doesn't make plenty of good arguments to support his views, but his seeming equation of any criticism of the field with crackpotist heresies is a cheap trick for a philosophy prof. 1: link 2: ▶ this video
