Week 4, Gravity

The function of gravity seems to change according to what is being discussed. For humans, gravity is the most palpable of the forces and the one that keeps our world together. Gravity is very important to us because it sets up the boundaries around the space in which we function. We need gravity to keep our bodies healthy as well. In terms of the bigger picture, it seems as though gravity keeps the macroscopic expression of the universe together. Without gravity, the universe would not have been able to organize itself the way it did. I don’t know what the exact function of gravity is, but without it reality would be completely different.
