Gravity vs. Antimatter

There will be a lot of upset people if antimatter falls up. Einsteins General Relativity theory is based on the equivalence of gravity and acceleration, meaning that "what" is in the gravitational field or being accelerated is irrelevant. An object's motion is governed by the geometry of space-time and it makes no difference what it's made of.

This'll be like a tug-of-war in which one person is pulling but the other pushing, so it'll move fast.

So, what happens with neutrons and anti-neutrons?

You know, you might be onto something there. That might be the beginning of us needing dilithium crystals.

Suppose we consider what forces could affect two isolated particles, one a neutron, the other an antineutron.

If the "new" gravitational theory is correct, F=G (-)(+)n²/r², where (-) is the negative gravity quantum, (+) is the positive gravity quantum, n is the mass of the neutron (and the mass of the antineutron as well), is the gravitational force present (negative sign would imply repulsive force).

There is no charge on these particles, therefore the coulombic repulsion is zero. The weak force and the strong force only remain to be considered. All these depend strongly on how proximate the two particles are. I suppose there could be a neutron - antineutron pressure (don't know how high) where gravitational repulsion would be overcome by the weak or strong force, and there would be a sudden annihilation with energy release. OR if one fired a beam of neutrons at an oppositely oriented beam of antineutrons, same result.

Another question: Is there a polyneutron theory of matter out there, why yes, there is, and thank you for asking (not that I am particularly a proponent of said theory)? Could there symmetrically be a polyantineutron theory of matter as well? Why yes, and thank you again for asking.

If a polyantineutron cluster sees a polyneutron cluster diffusing through the aether, does instant particle love take place? What if such an anti-matter cluster were to interact with surface plasmon polaritron cloud over a metal such as aluminum? Would it transpose itself into munimula?

I would be careful about what kind of bottle I chose for my anti-matter oat clusters. Things could get a little dicey.

So, what happens with neutrons and anti-neutrons?

It should be the same.

My understanding is that they already had the anti-hydrogen in another experiment. This experiment just piggybacks on that by shutting off the trap and seeing where the atoms go to meet their doom.

Does it fall down, or fall up? It just splodes...

It had to run into something made of ordinary matter to 'splode. Question is, can anyone hear it scream in a vacuum? Does it go "splat", "crack", or more of a "sploosh"?

Where would you find a place devoid of "ordinary matter"..? I think more of a pop! There is no vacuum...only partial vacuum....

ROFLMAO once again. Are people SURE about anti-matter, we think it always goes pop, and it is a large quantum of energy released, but what if it is repulsed by ordinary matter. The only way to get near enough then is what, opposite electric charge?

Well probably everybody here has seen a large discharge, positive to negative^{(or vice versa)....} I think if you just ramp this up to nuclear level, well you could have some idea...

Science in action!

Gosh, isn't science wonderful. That is why even a boiler drum that can hold over 1500 psig, has to be vented down below a certain pressure back down to atmosphere.

That must have been about the same number of Joules as a 50 cal round impact would make.

No pop when it hits the wall, just a couple of gamma ray photons, which travel through the vacuum just fine.
