Why Forces Matter

The ancient Greeks believed there were two fundamental forces – an attractive force they named “love” and a repulsive force they named “strife”. Our current understanding is that there are four forces of nature: the electromagnetic (it turns out electrostatic and magnetic are really the same thing) and gravitational are the most noticeable, as these dictate our everyday interactions. However, holding the nucleus together are the strong and weak nuclear forces that are only felt on length scales unfamiliar to us.\u00a0<\/p>\n

Forces tell us how things interact and will allow us to determine how the universe will evolve, how to build skyscrapers and faster or more efficient vehicles. They even tell electrons how to move in computer chips. However, much is still unknown – why is gravity so much weaker than the other three? If gravity is only attractive, why is the expansion of the universe accelerating?<\/p>\n
