So if you turn lets say, an apple to negative mass, what will happen? It will go up?

Negative mass particles repel everything, which includes other negative mass particles.
I'm not sure how strong atomic bonds are compared to gravity, but I think all its atoms would go their separate ways, chasing down stuff with positive mass.
If the apple stays intact, I think it would fall down (it is attracted to the centre of the earth) and the apple will exert a downward force on the ground (the ground is repelled by the apple). The apple is not sufficiently massive to actually move the ground out of the way so it appears to fall as normal.

gravity pales in comparison to electrostatic force and is completely shat all over by the strong force
unless you're an old star
and the apple would accelerate away from earth's gravity, though it remains a mystery as to how it would behave under other forces

I'm not sure why the electrostatic force would cause it to hold together. I wasn't saying the electrons would be torn from their nuclei. I was just saying that molecules might be torn apart or at the very least the apple would fall into pieces.
And why would it move away from earth's gravity if the earth has positive mass?

if ionic bonds are orders of magnitude stronger than gravity then do you really think that covalent bonds wont be?
and because an object of mass -m would cause the opposite curvature of spacetime that and object of mass m would, and matter on an inertial path would instead be directed away
[QUOTE=FreakyMe;45422458]What physicists call the 'higgs boson field' (I may be completely wrong). The hills are above 'neutral space', which is where objects with mass are attracted to and push into. Merely the act of staying above the space-field requires energy, so the ball is naturally repelled away from it. A well in space-time (as created by a normal object) requires no energy to move into and energy to escape. It is the opposite for a 'gravity mound', where it takes energy to move into it but none to be repelled away from it.
Think of it this way - There are two sheets of the universe, one above the other. The one which we know and the one which objects are attracted towards to gain mass. Objects that are massive are drawn downwards through the sheet of our universe towards the boson field, thus creating mass.
The well may be wide or very very narrow depending on the density and the size of an object. For example - Earth has a steep, narrow, but shallow gravity well where Saturn, being a gas giant, has a much less uniform density and produces an incredibly wide and deep gravity well. This may explain why the gas giants have such a massive 'zone' of stable orbits around them where moons can settle.
This is all purely unsubstantiated theory on my part though, based off of old scientific literature.
If anyone has a better grasp of the concept, feel free to correct me.[/QUOTE]
triple question marks usually suggest a nonserious question
Also it's simply called the Higg's Field, and it really has little to do with GR.

You really should try to sound less condescending. If you have any plans for a science career, you will often find yourself ignorant on certain matters and I'm sure you'd appreciate people not being twats about it.

i don't

I should rephrase that. If you have any plans for not sounding like a dick, you should try not sound like a dick. I can't tell you how to behave, but you give off a very elitist vibe. You could simply try to help people better understand scientific concepts without stroking your ego.
I've gone a bit off-topic, but elitism is a bit of a science PR issue that should get more attention.
[QUOTE=JohnnyMo1;45417901]Everything is attracted to positive masses and repelled from negative masses. [B]So two negative masses would repel away from each other.[/B] Also, a negative mass would essentially chase a positive mass. The positive mass is trying to move away from the negative and the negative is trying to move toward the positive.[/QUOTE]
Something about this doesn't bode well with me for some reason.

Probably the fact that it doesn't behave the same way as charge. It is weird.
[QUOTE=techtuts0;45423204]The higgs field is not related to gravity, I think you mean space-time. The higgs boson is a small ripple in the higgs field and plays no part in mass giving
Thinking of space-time as 3d space is just an analogy as shown in the xkcd. You are correct that objects with a greater density have greater space-time curvature
Feel free to correct me JohnnyMo1
I wouldn't say relative, the point of the laser is just imaginary, the photons are still travelling at the speed of light[/QUOTE]
I mean, the higgs field is related to gravity in the sense that mass is related to gravity and the higgs field is related to mass, but you're correct in that the higgs boson does not give mass.

Just remember to always bring your towel.
Negative mass.. hmm. Wouldnt it pull away from stuff then? Just get as far away from gravity as possible.
We all know that this thing had some negative mass in it:

That had anti mass, not negative mass.

It's an understandable mistake when you have things like antimatter, which you would assume from the name has anti-mass and thus negative mass, when antimatter actually has positive mass.
At first glance I thought this was an exoteric article.
Oh, I see, I was mixing up antimatter and anti-mass. My mistake.
