String theorists think that our universe is on a brane. If you can picture a whole bunch of branes all clustered together, like sliced bread, you can imagine that the big bang occurred when whamo! two pieces of bread bumped. This also explains gravity’s weakness… kinda.
Imagine that gravity is a rubber band style string and that electromagnetism is a string attached at both ends to a brane. The rubberband string of gravity would be free to float off- off into other slices of bread, I mean branes. Perhaps where gravity comes from is farther away (the end butt of the bread for example) and thus we have less of it by the time it reaches our slice.
So far, this is all I can figure out about String Theory. Some parts of me wish that it could be true. All the Star Trekian wonders that could arise from such a thing would be amazing. String Theory doesn’t solve for creation, however. If two branes smacked each other and the resulting force created and scattered our universe, where did the branes come from? Furthermore, if we are nothing but random miracles of science, then why is it wrong for me to kill my coworker? No, seriously, give me one good reason, because atheism is very appealing today.
