What is it about matter that causes objects to be attracted to one another?

Question

If all matter has some gravitational pull, and the only explanation to magnetism is electrical energy, that'd mean that all matter has it's own electrical fields. Even nonconducive objects that wouldn't conduct electricity. Are all things magnetic? Explain gravity's relation to attraction of objects.

Answer 1

Electromagnetism and gravity are, for practical purposes, unrelated. They are two of the four fundamental forces in nature, the other two being the nuclear strong force (what keeps protons and neutrons together in an atom's nucleus) and the nuclear weak force (responsible for beta radiation).

Gravity is by some 25 orders of magnitude the weakest of these forces, but as it works on a much larger scale, and at far greater distances, it's the most apparent on the scale we observe.

As to what "causes" gravity, there's no real answer. There are two postulated models that do a reasonably good job of describiing gravitational behaviour however. The first is quantum gravity -- that the gravitational force is carried by a massless particle called a graviton.

The second is related to relativity, and states that mass literally reshapes space to bend toward it, and that the result of this shaping is perceived as gravity.

In a sort of funny juxtaposition, it may be noted that much more is known about the theory of evolution, particularly in its mechanics, than is known about the theory of gravity. This has led some satirists to promote the alternative theory of "Intelligent Falling" to descibe how items are not, in fact, gravitationally attracted, but pushed toward each other by God.

Answer 2

Gravity and Magnetism is no way related to each other... Even Isaac Newton just said that gravitational force exists but he couldnt describe why it exists

Answer 3

Discovery Channel showed this really well...

ok lets assume that space-time is this really thin cloth...ok and all planets and heavenly bodies lie on it...in real life we see that when we put a heavy object on sumthin light....it weighs down...same thing with the sun....because it weighs down...it sorta pulls all the planets with it....

shucks i still cant explain gravity ON earth n teh other heavenly bodies.....but anyway...magnetism n electricity are not related....magnetism is caused due to magnetic fields....

Answer 4

Gravity and the electromagnetic forces are not the same thing. IN fact, one of the 'Holy Grails' of modern physics is finding out what they have in common.

Masses are attracted towards one another by gravity (or, in some cases, sex appeal ☺) but we know very little about the fundamentals of either.

Answer 5

To the extent of our current knowledge, gravity and electromagnetism are unrelated. We can calculate the gravitational force between two masses in a simple situation as

F = -GMm/r^2
proportional to the product of the masses, inversely proportional to the distance.

But why is there a gravitational force between masses? No clue.

Answer 6

Some matter has electric charge (protons and electrons) and all matter has gravitational mass (protons, electrons and neutrons). Magnetic force is caused by moving electric charge, but there is no "cause" for the electric charge itself; it is just there in protons and electrons. Similarly, gravity is just there in protons, electrons and neutrons, but it is separate and different from charge.

Answer 7

The theory of General Relativity can be paraphrased as
"Matter tells space how to bend; space tells matter how to move"

What we see as gravity, is the 4D geometric effect of mass on spacetime.

Einstein spent the last few decades of his life vainly trying to reconcile electromagnetism and gravity into one all encompassing theory.

Answer 9

hi chaitanya, a touch fantastic Ques. Physicists have lengthy been in question of information, what actually this GRAVITATION is ? I 'd prefer to ans. in factors : a million. the first ever attempt replaced into made via Sir Issac Newton ( as u should comprehend - The falling apple tale) 2. the conception Of established GRAVITATION obtained international acclaim and shortly replaced into generally happening. 3. Neither the technology, nor the requirement existed then to pass deep to the mechanism of this stress. via on the instantaneous, in the era of THE GRAND UNIFIED idea or concepts like : String, Superstring, great symetry or Membrane idea... we are guaranteed to poke into the operating and nature of each and every of the 4 established foces of nature. 4. right here got here Sir Albert Einstein to rescue inclusive of his wide-spread Relativity. He proposed that the area-TIME is a sheet it really is bent via mass causing the area bodies to slip in (basically to describe you actually) 5. on the instantaneous we've yet another aproach to this, thanx to QUANTUM MECHANICs. It signifies that as different forces ensue dur to the change of a few stress service debris, Gravitation too is an same. Its because of the change of certain stress service debris, referred to as, Gluons. Their life is yet to be prooved via the particle physicists. shall we see no matter if some or the different of those great Particle Acelerators are waiting to go back across it. 6. ultimately, we've yet otherwise to imagine ( if you're in the international of Superstrings ). It sugests that Gravity ( the weakest between the 4 forces ) is definitely "leaking" from "different Universes"(those ought to have as many as 11-21 dimensions) and reaching our four-dimensional international. nicely desire that in some unspecified time sooner or later, as we've already managed forces like "electromagnetism", we 'd also be able to make stronger or regulate Gravitation with our own will. desire day after today we may be able to improve some capacitors which may make us experience weightless each and every time and anyplace we choose. Bye...........

Answer 10

gravity and magnetism are completely different forces
