hypothetically.......
would it be possible for an object to allign it's particles/atoms/molecules/whatever such that it could be repelled by a celestial mass, similar to two magnets that repel each other when similar poles are alligned?

i dont think it could align its particles...
but i suppose if something was magnetic already, and a celestial mass was highly magnetic...
thats just like two magnets...

Very little. See unified field theory.

You want the truth? YOU CAN'T HANDLE THE TRUTH!




...okay here it is: It involves non-dairy creamer.

Gravity is an attractive force between two bodies. It's proportional to their masses and inversely proportional to the distance between them. It is not possible to modify matter in a way that gravity will act as a repelling force.

Electromagnetic force is a force that acts on moving electrically charged bodies in a magnetic field.

Not much of a science buff lately, but what about a large body of anti-matter. Would that make "anti-gravity" ? :)

Anti-matter has the same properties as regular matter with the exception that the particles are reversed in charge. When they come in contact with matter the matter and anti-matter covert to energy.

i don't know unified field theory. but i have always suspected them to be the same =) essentially...

--

anyway, gravity can be best explained in 4d space =)

magnetism just freaks me out sometimes...

at least you did not ask the difference between electricity and magneticism ;-)

wait, why would anti-matter "generate" antigravity? that would make no sense ;-)

Gravity is generated by zortons,
magnetism by zitrons...

The field is inversely proportional to the square of the tron/rton functional radius.

You earth beings can never figure out even the simplest of things !

Gravity is an attractive force between two bodies

so is magnetism

is there a better explanation of gravity that would differentiate it from magnetism

and a microwave cuz noone knows quite how they work

*kat. <-- saw that episode of pinky and the brain too.

No magnatism is a force that is the attraction or repulsion of opposite or like electrical charge. Has nothing to do with mass.

and that, triple shot, is why antigravity makes jorken smile, I think.

I know it makes me smile for that reason.

You should take a look at quantum electrodynamics. This tells us that electricity and magnetic forces are the result of the interaction of (electrically charged) particles. Similar theories (known as gauge theories) will one day unite all known forces (graviational, electromagnetic, strong and weak).

BTW gravity and electromagnatic forces show some similarities: both forces operate over long distances and their exchange particles (gravitons and photons) have no mass.

are we sure gravity is not based on magnetism?
like spinning fields?

isn't it true that in a motor, a larger mass of electrical field is stronger than a smaller mass?

and what about the speed of the mass?

Gravity is not based on magnetism.

Gravity is an attractive force based on mass (all particles in the universe exert a natural attractive force on all other particles in the universe, it may be strong or weak, and may be cancelled out by other forces, but it is always there)

Magnetism is an attractive or repulsive force based on electric charge

They are similar in many ways, but the basis of the force is different.

There are four fundamental forces acting between particles:

- strong nuclear force
- weak nuclear force
- electromagnetic force
- gravity

First two are not important on a macro scale, while the last two are. Electrical charge is a necessity for electromagnetic force, while for gravity it isn't.
