Christopher Caudwell has some pretty excellent critiques of bourgeois science. Scientific progress has stalled because it is no longer profitable for the bourgeoisie, and the world’s best scientists are all bootlickers, at least inside the imperial core. There’s a reason the best physicists in the 20th century were all communists. But China thankfully is turning this situation around.

Gravity is easy, it’s the entropic magnetic charge from protons and electrons.

one unresolved corner of physics

Hardly! People board airplanes every single day and we still don’t fundamentally understand the mechanisms of how lift works.

Lift works the same way a tennis racket does.

We know exactly why and how.

I heard that it was just the angle of the wings redirecting the air downwards as reaction mass, like how a rocket engine shoots air downwards.

It is both, but the pressure one contributes more to lift. You can see this when a wing stalls, the airflow separates from the upper surface and the pressure difference is gone. The angle of a stalled wing still means air is directed downwards, but the overall lift is much smaller.

At least that is what I’ve been told anyways

When I thought there was higher pressure under the wing that pushed the plane up, I was happy. When I started thinking, instead, about little vacuum vortices above the wings pulling them up instead, I was suddenly much less comfortable with the whole proposition. Given the options and the limited effect on my daily life, I’m gotta go with Newton over Bernoulli on this one.

We know vacuums don’t “pull” things. Instead it’s air pressure elsewhere that isn’t balanced by the vacuum that moves things in the direction of the vacuum.

Speak for yourself. I’m a student pilot and most of my instructors (who are either retired airline pilots or are trying to build up flight hours to qualify for an airline job) don’t understand the science behind it. To be fair, understanding the science doesn’t really help you fly a plane…

I don’t get it, how can you know how it works but not how? Or is it some philosophical why are the laws the way they are?

So here’s my lunesta fuelled dea on gravity.

Gravitons, like the rest of the standard model, are real. In order to measure them, we need incredibly high energy collisions.

In attempting to do this, our universe was created on accident. This is because our universe is in a black hole. But the cool shit is that black holes are really portals into our own universe. Instead of the energy spontaneously appearing as measurable particles, it’s dark energy causing the expansion of the universe. The Dark energy ends up being gravitons, because gravitons are a boson and only interact with matter with the gravitational force. the black holes, then, take in “normal” fermions and bosons and spit out the gravitons. The graviton release causes an expansion of space time by “pulling” space time with it.

none of that is backed up by anything

You’re sure the universe wasn’t created by purpose? You’re sure it was on accident?

gravity applies to everything with mass. But also light which has no mass.

Yeah but if you scratch a little bit the surface, the comparison falls quickly. Okay, magnetism has two signs. Why not gravity ? Why does it attract and not repel? Okay, magnetism is carried by photons. What carries gravity?
