The authors ask what #stringtheory definitively cannot create. Their answer points to a single exotic particle that could show up at the #LHC. If that particle appears, the entire string-theory edifice would be, in Heckman's words, "in enormous trouble."

"We're not rooting for string theory to fail, we're stress-testing it, applying more pressure to see if it holds up. If string theory survives, fantastic, If it snaps, we'll learn something profound about nature."

Can the Large Hadron Collider snap string theory?

In physics, there are two great pillars of thought that don't quite fit together. The Standard Model of particle physics describes all known fundamental particles and three forces: electromagnetism, the strong nuclear force, and the weak nuclear force. Meanwhile, Einstein's general relativity describes gravity and the fabric of spacetime.

Sicim Teorisini de Boyutlarını da 10 Dakikada Anladık

Ben hâlâ anlayamadım!

Yıllar önce Membran Teorisini duyduğumda çok mantıklı gelmiş ve Sicim Teorisi ile ilgilenmeyi bırakmıştım

Çünkü Membran Teorisi bu Sicimlerin birbirine bağlanarak bir zar oluşturduğunu iddia ediyordu

Hâlâ Sicim Teorisi ile ilgilenmek -daha İnsan bedeninin neye benzediğini anlayamamışken- deri yerine hücrelerle ilgilenmek gibi bir şey değil mi?

String theory’s nightmare: Ghostly five-particle family promises to uncover dark matter

Meet 5-plet: A group of ghost particles that could snap string theory

Instead of asking what string theory can explain, a team of physicists searched for what it absolutely can’t.  This led them to 5-plet, a strange five-member particle group.

Can one vanishing particle shatter string theory — and explain dark matter?

Can one vanishing particle shatter string theory — and explain dark matter?

Scientists are on the trail of a mysterious five-particle structure that could challenge one of the biggest theories in physics: string theory. This rare particle—never seen before and predicted not to exist within string theory—might leave behind vanishing tracks in the Large Hadron Collider, like ghostly footprints that suddenly disappear. Spotting it wouldn’t just shake up physics theory—it might also reveal clues to dark matter, the invisible stuff that makes up most of the universe.

...and/or (hedging my bets...if #StringTheory can so can I!): Our basis for what total energy in the universe *should* be may also be flawed and ultimately relate back to the "biggest blunder," Einstein's cosmological constant which never really died.

In this paper, we:
*Establish the notion of epistemic curvature
*Demonstrate the utility of this framework with a rigorous worked example from string theory.

Aristotelean logic has been unsatisfactory in the quantum world. Measurement scenarios are context-based, due to locality, and require a local-to-global gluing tool.

FAs come to the rescue. With sheaf-like structure, we ranslate between different epistemic frameworks seamlessly.

@TheReturnOfPEB watch the spacetime ball under the cup: 3 + 1 is now 1 + 3... Ta-da!

I'd like to see the author of that highly questionable paper even try to account for General Relativity in such a scheme.

Meanwhile, #StringTheory says: "Nah, 57 1/2 dimensions is better"

We think #gravity is a "particle" and #time (which, as we define it, is entirely our imagined #fiction) is as "real" and spatial dimensions, of which there could be 2, 3, or many more (#stringtheory)...which means we "know" practically nothing!
