http://www.teachastronomy.com/ There are four fundamental forces in nature. In decreasing order of strength, there is the strong nuclear force; the particles involved are quarks. The strong nuclear force holds atomic nuclei together. Twelve times weaker is the electromagnetic force, an

http://www.teachastronomy.com/ Unification is the idea that the four fundamental forces of nature are all manifestations of some simple unified super force. On the face of it, this seems unlikely. The four fundamental forces span a range in strength of a factor of ten to the power forty.
