fuck off, i'm incredibly intelligent, and so are many other scientists and physicists, who know that string theory is absolutely bogus and the only thing they're doing is stringing along more grant money while they publish nothing of value

Because it was a promising theory in the 80s-90s that got picked up by the most prominent American physicists. As a result of all that clout, all of their competitors (LQG, twistors) got crumbs for funding. Then it became clear in the 00s-10s that string theory is going nowhere, so all those prominent boomers and their cult followers got scared of not being able to milk the grant cow anymore and started to come out with ridiculous unscientific copes like le multiverse or “it’s a framework not a theory”.

Notice how I specifically said American. String theory doesn’t have a monopoly in Europe. You’ve got people like Penrose, Rovelli, Thiemann and others working on the alternatives. Europeans aren’t little children who need shiny keys jiggled in front of them, so research funding is a lot less clout-based.

the string theorists made up extra dimensions to try to make their model work, but there is absolutely no physical evidence to substantiate their claims of extra dimensions. I can program a video game world with arbitrary rules and get interesting results, that doesn't mean I'm doing physics research that's actually connected to reality or worth dedicating 40 years to.

QFT already does that. What you want to say is that it unifies them. Why they need to be unified never goes beyond “it’s pretty this way”.

you can't prove it, and even if you're right, maybe the correct theory can benefit from the advances string theory is doing on mathematics

at this point "it's wrong" should be the default position, if a few of them want to continue on in the vain hopes they'll find something to validate their years of effort, let them. But don't screw up the entire institution because a few nerds have bedazzled you with their math.

> gravity can't be explained in qft without general relativity
So? Just treat the Einstein-Hilbert action as an effective action. You can calculate all the scattering cross sections up to arbitrary order as long as you’re below the Planck scale. In fact, that’s how Hawking calculated black hole entropy in the semiclassical limit.

Of course, perturbation theory breaks down above the Planck scale, so you need non-perturbative methods. But this is nothing new as QCD does that at the Hadgedorn temperature. I like LQG because it’s essentially a very sophisticated cousin of lattice QCD instead of that pompous, arrogant bastard string theory who sits in his own corner and tells everyone he’s better than them.

There are two broad domains of physics.
Geometric gravity
Discrete lie algebras for particle physics
The former describes GR whereas the latter describes the standard model of particles
Due to the success of the standard model, it's claimed a GUT and a TOE exist via quantizing gravity
This belies the point that even QFTs have fundamental ontological problems that even mathematicians acknowledge
Meanwhile geometric gravity is ontologically well founded, albeit a host of issues arise in cosmology due to poor detection methods
In short, we need to stop talking about quantizing gravity and instead discuss geometrizing particles

kek what a pseud thing to say. Lie algebras are vector spaces. The ones used in the Standard model are vector spaces over complex numbers. The representation space of the groups is discrete, but this is only because they are compact. There are, of course, examples of non-compact groups in QFT. For example, the non-linear sigma model used in condensed matter physics has the diffeomorphism group of a manifold as its gauge group.

Estimate: how many individuals over the past 20 years have been doing research?

What are the grandest fruits of their results, considerations, claims, hypothesis', theories, understanding, expeirment?

They believe other methods of describing the way the universe exists were and are in adequate in ways: what are those ways, and what is their evidence their ways are making progress and better?

Gravity is geometric (apt word, General) because it's the largest (space) and we can't detect it's particulate (unless you count the EM field)

Would you describe wind or a hurricane per particle, or because it's such a large field of energy densities and tensities, but relatively (though large) localized focus, would you broadly describe it's thick and thin and boundaries and compression gradients of 4d geometry?

Would you describe water waves per h20 molecule, or a geometric field of water action.

String theory is a purely bosonic theory that can't work without supersymmetry. There are no flavor-changing neutral currents.

I don't like citing fallacious arguments but in this case it's appropriate to point out how you're affirming the consequent. Friendly reminder that is no evidence nor well-founded reasoning for gravity being a particle. None. Nada. Zilch.
