The universe is held together by four known forces...the strong nuclear force, Electromagnetic force, the weak nuclear force and gravity. The strong nuclear force is responsible for the formation of protons and neutrons with quark combinations, and also the combining of protons and neutrons in atomic nuclear. It has limited range. The electromagnetic force, is that force associated with electricity and magnetism, and is a result of the exchange of photons, [the electromagnetic field quanta] It can be either attractive or repulsive. The most common example is Sunlight. It is also responsible for the orbits of electrons [negative charge] around atomic nuclei [positive charge]. It has infinite range The weak nuclear force is that force responsible for radioactivity, and the decay of unstable subatomic particles. It has limited range. Gravity is that force which shapes the universe. It is the attraction between all masses, no matter how big or how small. Gravity only ever is attractive and is infinite in its range. Our best model of gravity is GR, and entails the warping, curving and twisting of spacetime in the presence of mass. Gravity is spacetime geometry and spacetime is the universe framework. In essence then gravity within GR is not really a force per se. While the weakest of the four forces speaking comparitively, it is also accumalitive. Gravity at its most accumalitive power is shown with Black Holes...regions of curved spacetime where matter has collapsed to beyond its Schwarzchild radius, and so that the escape velocity exceeds "c" Here are two illustrative links that will help to explain.... http://hyperphysics.phy-astr.gsu.edu/hbase/Forces/funfor.html https://wtamu.edu/~cbaird/sq/2013/05/22/why-is-gravity-the-strongest-force/ Other associated threads can be found at.... http://www.sciforums.com/threads/why-are-things-in-space-the-shape-that-they-are.163155/ and http://www.sciforums.com/threads/the-early-universe.163207/ and http://www.sciforums.com/threads/flashback-einstein-was-right-space-and-time-bend.163108/ The above narrative by me is pretty basic and any errors, alterations and/or corrections are welcome. Including of course any elaboration that may help The main reason I saw the necessity of posting this, is because we have the continued nonsense and ignorance being portrayed in the fringes by river.
