Gravity???

Question

O.k. I know that like gravity is when two molecules like attract to each other. And the more the mass, the more gravity. But what is gravity? Like what causes it? I'm just real puzzled here. Somebody help me!

Answer 1

Good question, I and the rest of the scientific community wishes they knew the answer.

Galileo experimented with gravity, and Isaac Newton created the math that explains how it works, but we don't know what it actually is. In that respect we are no smarter than when we were cavemen.

Light, radio, microwaves and a lot of other radiation is created by the photon; a subatomic particle. We know that electrons create electricity. The theoretical particle for gravity could be the gravitron, but no one has ever isolated one. We know the speed of light, we know how fast electrons move, but we have no idea how fast gravity travels, it just is. We don't know how to create or block it. We can create electrons and photons and we can insulate and block both of them; we have no idea how to do that with gravity.

Gravity is a strange force. It creates the strongest force in the universe; black holes, but it can be defeated by something like a magnet. One theory is that gravity may be expressed by a force from a higher dimension that could explain why we can't see it.

Einstein’s Special Theory of Relativity calls for at least 11 dimensions, no I don't understand the math it is just to complex. We have proved the Special Theory of Relativity through experiments. When you travel on the Space Shuttle you travel faster than most people do and time actually slows down for you; it has to be measured with atomic clocks, but it does slow down.

String Theory can call for over 20 dimensions. Something has to be in all those dimensions and gravity could be one force that is there.

Electricity and magnetism are the same force; all created by moving electrons. According to Einstein’s Unified Field Theory gravity and electricity should also be the same force. We have proved that the strong and weak nuclear forces are just expressions of the force of electrons so Einstein is right on 3 out of 4 forces.

Either we can't see gravity because we can't see into its dimension, or we can't see gravity because we haven't gotten down to the fundamental particle yet. The new CERN particle accelerator in Europe is the largest one in the world and it is possible that experiments there could find the gravitron; if it even exists.

Answer 2

bet money space time motion and gravity are all the same thing and that the only direction one can really go is forward . what is direction with out motion

Answer 3

Hmmmmm... gravity is a force that pulls you down bwaahahah

Answer 4

Gravity is an interaction between two particles that have mass. The more particles, the more interaction.

Particles that are closer together have more interaction than particles that a farther apart. In other words, the closer two masses are to each other, the more attractive force there is between particles.

How this comes about depends upon your viewpoint - are you talking about small particles, or big things like planets and stars?

For small particles (at the level of atoms), the Standard Model tells us that there has to be an exchange of carrier particles, which we call gravitons. These particles have never been observed, but have been predicted to exist. This is the essence of quantum gravity.

At the other end of the scale are large objects, like the Sun, the Earth, and you and me. According to the General Theory of Relativity, the presence of a mass warps space around it. The more mass you have, the greater the curve.

Amazingly, gravity is by far the weakest of all known forces. The nuclear force and the electromagnetic force are billions of times stronger than gravity.

"Why does it seem that gravity is so strong?", you may ask. It is because gravity is always attractive, unlike electromagnetism, which can both attract and repel, and it acts at long, long distances, unlike the nuclear force that is only seen when quarks are next to each other in atomic nuclei.

The bottom line is this: gravity is a property of matter. The more matter you have, the more gravity you have.

Answer 5

That's a good question, and one we're still working on. We know that gravity is a direct consequence of mass, but exactly how that information is transmitted (waves, superluminal communication, what exactly) we're still not sure. Check back in 10 years after LISA is launched to see if it can detect gravity waves. The best we can say is that gravity seems to distort spacetime (the 4 dimensional space we live in).

Answer 6

It is an area of active research. No one know exactly what gravity is or why it exists. I do believe that if/when we do figure it out it will be one of the most important scientific finds in the history of the human race and will be much more profound than anyone can imagine.

As a skydiver I am proud to say that in the war against gravity I will be know forever as one of the freedom fighters! :)

Answer 7

As on date it is a mysterious force of attraction.

I am not yet sure whether we have a counter gravity force as well. It is just doing rounds in my brain. Instead it should have done its rounds in the brains of brilliant physicists'.

But then it is just like asking why an object has mass and weight? Because it is just inherent property. An expression to tell that I am, "Cogito ergosum," dear. So does this massive objects do speak to each other by the way of gravity, "cogito ergosum," dear.

Answer 9

very good question........if we ever discover just how it work,s we,ll be able to make space travel much more realistic.....little is known about just how it work,s.....what is known is it,s effect,s on everything.....yes...there is a connection to the density of a mass....but the actual mechanic,s have ...so far...eluded us.

Answer 10

isn't that obvious
