Because we can know nuffin, when you put 2 metal plates near each other the particles that exist but actually dont, bur maybe generate a force (push) between the plates. All because we can no nuffin.

Orthogonal means two things are linearly independent. Linearly independent means that amount of one thing has no affect on the amount of the other thing. You can have as many things linearly independent as you like.

Mayonnaise and tuna are linearly independent. For short distances on the surface of the earth, north and east are linearly independent.

Up and down are not orthogonal, but an electron is either deflected up or down and an electron being observed to be deflected up is orthogonal to observing an electron being deflected down.

Does that mean an electron can be deflected up and deflected down simultaneously?

But what I said holds for all things. You either observe your mother in the kitchen or in the bedroom. You can't observe both simultaneously unless the bedroom is a kitchen... So if you live in a sane house, observing these two separate states are orthogonal, which is not surprising and it's not surprising for the electron. It's just surprising that beforehand the electron was in some sense doing both simultaneously.

How do we know?

Quoted By:

Around any gravitating body, there exists an accretion disk of in-falling matter. Einstein's laws of General Relativity (which, as a result of applying Special Relativity to gravity. Rather, that gravity must travel at the speed of light.) predict it.
Another thing predicted by General Relativity (GR) is that gravity waves exist. These are ripples throughout space-time like ripples on the surface of a pond (only the surface is in four-dimensions). The motion of these waves Einstein first predicted by applying Maxwell's equations to his own SR in what became called the First Newtonian Approximation (1PN).

Here's where things get cool:

Through 1PN, an accretion disk can be thought of as moving point charges travelling around the center. For an in falling plasma or gas, this infalling (which is a more efficient way of converting potential energy to kinetic energy than nuclear fusion, about 25 times more efficient btw)
Can be appropriately modeled as magnetic disks. Only instead of electromagnetism's repulsion and attraction, we are left with only gravity's force of attraction. This can be modeled quite easily by making the disk have one charge and taking a point charge and setting its charge to the opposite. In this way, we are emulating very simply how gravity waves interact using 1PN. And what we actually found was that a point particle will at low speeds will be trapped by the disk (duh), then at slightly higher disk speeds, the test particles begin to be flung out of the disks, almost straight up. This is weird. It suggests that there would be some sort of bipolar out flow out of all disks.
Well no because the theory also demands that the disk needs to be spinning at a certain speed. Only massive graviting bodies can cause speeds that even approach the speeds at which this phenomonon is present. How about a blackhole? Blackholes actually have every speed that is possible within their accretion disks.

Quoted By:

Anyway, as the disk speeds increased further than that, the point particles began to be attracted by the current of the accretion disk, it will actually start to follow it a little bit more every time you increase the angular velocity of the disk.
At 1/3 of the speed of light, the effect's trend is clear, it is moving, closer and closer to a corkscrew shape. Combined with frame dragging effects (in which a massive spinning object actually pulls against space-time itself to the point where space-time is twirled around it), you can see the paths falling into an even clearer corkscrew orbit towards the blackhole's spin axis. This process is modified version of the Blandford-Znjeck process, which describes how polar jets around supermassive blackholes blast particle beams out that can rip other galaxies apart (look up "Death Star Galaxy").

Only this in fact predicts that it is gravity that is the dominant force not the electromagnetic forces generated by currents of fast moving ions in the accretion disk.
This flies in the face of forty years of research.

And tomorrow, I get to work on proving it, with a supercomputer.

Fuck yeah.

>Orthogonal means two things are linearly independent.
otrhogonality is a sufficient but not necessary condition for linear indepenence

>Linearly independent means that amount of one thing has no affect on the amount of the other thing.
no, it means that the expression of some arbitrary quantity as a linear combination of your two linearly independent quantities is a unique expression, or, rather, that the two quantities are not scalar multiples of each other.

mayo and tuna are only trivially linearly independent due to the virtue of no linear dependence, because they are fucking mayo and tuna.

in R2, any non-parallel vectors are linearly independent. they don't have to be orthogonal.

what the fuck are you on? i'm drunk and your post still seems very wrong

Quoted By:

The idea of differential geometry is to approximate shapes you don't understand very well but that are reasonably well behaved, ie. shapes that would look flat if you were on them and were small enough, by linear objects in order to get local information.
The way you actually do that is by cutting your shape in small, "flat", pieces and making charts of these flat pieces, just as the explorers did when they were going around the earth, which is not flat but looks flat everywhere because we are small enough not to notice (if we were several miles tall, we could notice the curvature of the earth)
