Electron Attraction and RepulsionJune 1st Fact-of-the-Day
Gravity attracts two electrons towards each other, but their identical negative charges cause an electrical repulsion force. If the gravity force and the electrical force were equal in strength there would be no net force of attraction or repulsion. However, it is well known that electrons repel each other, so the electrical force is stronger than the gravitational force, but how much stronger? The force ratio is enormous. The electrical force is 4.17x1042 times stronger than the gravitational force regardless of the distance between two electrons. There is a strange thing about that ratio. If the age of the universe is 8.34x1010 years, the age of the universe is 4.17x1042 times greater than the time required for an electromagnetic wave to pass across a proton (10-24 seconds). So, is the gravitational constant related to the age of the universe? Probably not, but it might be. ©2005 Martek International All rights reserved.
