ds quarks together and holds protons and neutrons together withinthe nucleus. It is really strong within the nucleus, but very weak outside. It is virtual particle is a gluon. The weak nuclear force is the next to the strongest. Its particle is called massive vector bosons, and they are W+, W-, and Zo. This is responsible for radioactivity decay range at 10 to the negative 15 meters.All matter is attracted to everything else, and we see the effects of gravity because we stay on this planet. The universe is always accelerating and maybe it is repulsive gravity or maybe it is the fifth force actiing repulsive. We do not know which it is because we have not built a tool that will answer this question. Abdus Salam and Stephen Weinberg united the electro force and the weak nuclear force into the electro weak force, so now there are only three forces. So far there has been no clear theory to unify gravity with the other three forces, but it is thought to be accomplished at high energy levels. Only the heat of the Big Bang would be enough to unite the four forces. The inflationary model was proposed by Alan Gouth in 1981, which makes the universe and intelligent life in it a more probable event. This says that the universe went under a phase transition, or a breaking up of symmetry. For example, the freezing of water from a liquid state (water) to a solid state (ice). The inflationary model is widely accepted today, but people are starting to doubt the reality of cold dark matter. Perhaps there are Machos (massive, compact, halo, objects), or maybe there are tons of black holes. Saggitarius is running into the Milky Way and it is holding together rather well. Perhaps there is some other kind of matter that we do not know about. The inflationary model starts like the Hot Big Bang model. Supposedly, less than a second after it blows, it drops from infinite to 10 to the 28 Kelvin. During this period there is a symmetry breakin...
