Do antimatters obey the law of gravitation? Tell me sth about antimatters......?

Question

Try not to introduce 32-letter words in the answer. Try ur best.....

I know that they r the opposite of matter- positrons instead of electrons. But I would very much appreciate a description.......

Answer 1

Yes, both matter and anti-matter are subject to laws of gravitation. Gravity is a property of particles with "mass", regardless whether they are matter or anti-matter. By the way, the term anti-matter sounds very exotic, but it is just a label that describes a particle that has the opposite electrical charge and spin of another particle with identical mass.

So electron has an anti-matter partner called the positron, which has a + electrical charge and a -1/2 spin. Similarly protons have anti-protons, which have - electrical charge and also opposite spin. Neutrons have no electrical charge but does have spin; hence, it also has an anti-matter partner with opposite spin.

BTW, photons are bosons, and has no anti-matter partner like an anti-photon. As a matter of fact, most matter/anti-matter collisions result in the release of high energy photons. Therefore, graviton, another type of boson, also do NOT have anti-matter partner like anti-graviton. There are no bosons with anti-matter partners, because all bosons are force-communicating particles, i.e. photons communicate the electromagnetic force, graviton communicate the gravitational force, and gluons communicate the strong force.

I seriously don't understand why people make up stuff like this in their answer. It really doesn't impress me.

Answer 2

Anti-matter is not stable enough to last for more than a few fraction of a second. I would like to think that if if were stable. It would obey the laws of physics. Data in startrek has a positronic brain. Positrons are the anti-matter equivalent to electrons

Answer 3

Antimatter is "opposite" in the sense of electrical charge and some other quantities. But mass is not a charge. In fact the mass of an antiparticle is equal to the mass of its regular partner.

Answer 4

Interesting question.

Scene 1 : Lets say there are only two objects in this universe earth-a and earth-b(both made up of anti-matter), this for sure i believe will obey law of gravitation.

Scene 2 : Lets say there are only two objects in this universe one earth-x(made of matter) and earth-y(made up of anti-matter).
Here I wonder what would happen, as per experiments matter and anti-matter are supposed to attract each other and annihilate each other and end up as pure energy.

But I really wonder if the "law of gravity" would be exactly same as the law as that governs the "matter-matter" or "antimatter-antimatter" interactions. Probably "matter" and "anti-matter" should attract each other very strongly.

If we consider "Graviton" to be true to be causing the "gravitational force", then there must a "anti-graviton" which could complicate things further :)

INTERSTING ALTERNATIVE : If "Gravitons" are true, then it means two objects(made of matter) are "gravitationally attracted" due to exchange of "gravitons". So two anti-matter objects must be "gravitionally attracted" due to exchange of "anti-gravitons".

So may be there is no "gravitational attraction" between matter and anti-matter, because matter only has "gravitions" and anti-matter only has "anti-gravitons".....basically matter and anti-matter do not speak the same language.

Answer 5

NO one really knows if antimatter falls up. Most physics types think not but that they too feel the force of gravity, attracting things.The only diff. between matter and anitmatter is electric charge, that's all. Its nothing that weird or crazy or sciencefictiony.

Answer 6

You answerd your own question when you said that anti-matter has the opposite charge of matter.
Since it has a mass it curves space, hence it has a gravitational pull. conclusion: it obeys the law of gravitation...
A particle of anti-matter and a particle of matter will cancel themselves out if they comes in contact. A photon of energy will be the result of their cancelling each other out. Therefore the energy realeased is proportional to the mass of both. IF IT HAS A MASS IT IS SUBJECT TO THE LAW OF GRAVITATION!!!

Answer 7

waser matter? Now I have a headache.
