gravitons aren't real

This experiment will give a hint towards whether that's true or not.

How have they isolated the eletromagnetic component of the diamonds from interacting? Is this why it is super cold?

How do they know that the diamonds have fallen enough? What if gravity has thermal time, that takes the span of the universe to correlate? Ex. the non-perturbative quantum effects take place during another phase of spacetime.

I don’t know, gravity requires weight, and quantum mechanics might have atomic weights.

mass not weight, and quantum objects of course have mass, that is not the problem with unifying general relativity and quantum mechanics. The problem is that general relativity only works if you make the assumption that spacetine can be stretched or compressed infinitely and that contradicts what you see in quantum mechanics where everything can be broken down into small indivisible units. Eventually you reach the size of those units, and then how do you compress space any more from there?

Additionally trying to unify general relativity with quantum mechanics leads to the black hole information paradox, but I dont really see that as a problem with grand unification, because I personally find the holographic principle to be a very likely theory that would explain away that problem.

Its not space getting compressed its the planck scale degrees of freedom in space being compressed.

Say space is made up of planck length lattice. A photon can jump from one coordinate to the next one at the speed of light.

Now add 2 galaxies with super massive black holes in the centers to the lattice. Each of the black holes are compressing the planck lengths toward themselves at the expense of stretching them out between each other. But the speed to jump 1 planck length inside the galaxies and between them is still the speed of light. It's the same distance.

But the relative time it takes to jump a stretched planck length is exponentially greater relative to the time to jump a compressed one.

Eventually "space" stretches so much that the relative time for a photon to jump becomes essentially infinity and the galaxies can no longer see each other. They are in seperate universes now.

So thats cosmic inflation. Now just realize that the space at the edges of galaxies is stretched out more than we think. You no longer need dark matter or gravitons.

Now realize the compressesing and stretching is just an illusion emerging from varying informational complexity densities being processed at a universal rate.

Now realize this compression happens at every scale, down to people moving to cities. A city is like a rural state shrunk down by "gravity" with shit happening much faster. It's all just systems maximizing future degrees of freedom. It's really fascinating.

And then there is the whole other topic of qubits. Little exploratory experiments groping around to optimize probabilities and collapsing to the best one. It's the same thing as natural selection!

Wouldn’t gravity allow for the stretching you’re discussing? If gravity stretches, then the item can compress again, giving an infinite amount of compressions, as long as gravity can be applied.

And the article states that gravity can’t be measured, yet we use the gravity around stars as a lens to see further into the distance, or we use the refraction of light warped by black holes to actually see the black holes...why is it that we can’t measure gravity? Or is it that we’re looking for the gravity element? I got a little confused there at the end and was wrapping my head around it.

There's no particle. It's much simpler. Finite and discrete space is getting stretched and compressed. Which is how we perceive the relative processing speeds of different information densities in 3D spacetime, with a universal processing speed C. Which is plain entropy. That's all gravity is. It's a problem for information theorists (in the sense of a problem that can be solved). Particle physicists will never find gravitons or dark matter because they aren't a thing. It's emergent from how information processes.

Discrete space breaks Lorentz symmetry, so that's a major problem.

[–] Dougal_McHaggis 0 points 1 points (+1|-0) ago  (edited ago)

3D space can be represented as 2D digital bits, as holographic principle says. Which is discrete. The black space "stuff" is just a conceptual perception of the relationships between information processing. Fundamentally it's discrete bits. Space isnt really anything.

We can sort of measure it, you know distances and gravity, but not really. Thats what people are still trying to do though.

If it was found that lorentz symmetry, like entropy, is just an emergent property at the macroscopic level, would it actually invalidate anything about general relativity? It seems to me that einstein's equivalence principal is really the only thing that needs to hold true all the way down.

edit: disregard, I see now what happens if you try to do a lorentz transormation on something the size of a plank length.
