gravity ???????

Question

Does gravity and magnetic fields hold everything together?
Without gravity would everything cease to exist because the universe and star clusters are like held together by gravity but atoms are held together by positives and negs

Answer 1

gravity is the force responsible for holding clumps of matter together. the electroweak force is the combined forces of electromagnetic radiation (which in itself is composed of electricity, magnetism, and light, with the photon being the messenger particle) and the weak force, which is responsible for radioactive decay. the strong force is responsible for holding together protons and neutrons, which are composed each of 2 up quarks and 1 down quark. without anyone of these forces, the universe would be a completely alien and possibly inhospitable place for life.

Answer 2

I waited before I answered this because
I don't really know , but I can try:
Gravitation is a phenomenon through which all objects attract each other. Modern physics describes gravitation using the general theory of relativity, but the much simpler Newton's law of universal gravitation provides an excellent approximation in many cases. Gravitation is the reason for the very existence of the Earth, the Sun, and most macroscopic objects in the universe; without it, matter would not have coalesced into large masses (stars and planets) and life, as we know it, would not exist. Gravitation is also responsible for keeping the Earth and the other planets in their orbits around the Sun; the Moon in its orbit around the Earth; for heating interiors of forming stars and planets to very high temperatures, for the formation of tides, for rising hot air or water (convection), and for various other natural phenomena that we observectly.
Gravity and Magnatism are seperate forces.
If one or the other would result in our destruction is a rather moot point. Look more to Nuclear Threats.

Answer 3

Essentially yes. Gravity is the glue that holds the universe together. Electromagnetic forces (positive and minus) rule in the micro world. The world of atoms. But gravity rules in the macro world...the world of planets and suns.

Answer 4

Actually, there are four forces that help keep our universe "held" together, and gravity is the weakest of the four. These are, in descending order of their strength

1)Strong nuclear force
2)Weak nuclear force
3)Electromagnetic force
4)Gravitational force

Strong and nuclear forces bind elementary particles together, electromagnetic force is related to the charges of these particles, and gravitational forces act more at the macroscopic level, and are related to the masses of objects and the distances between their centers.

Answer 5

Gravity and magnetics have nothing in common .

Answer 6

There is no gravity, the Earth SUCKS!

Answer 7

good question!

Answer 8

kkk.....the question alone has confused me!
