It is very hard, but i believe it can be done without the need of inventing 11 dimensions for matter and 26 dimensions for force, as have string theorists done. Do you believe in string theory? |
Dimensions are human invented. hmmm... I don't think so then it would be much like telling that universe is there because u are there. Dimensions are the understanding of human thought. That doesn't mean they are human invented. And yes we can explain the universe in a much simpler way than giving all those extra dimensions. Space time is continous is what i believe but it does become discrete at special circumstances like beginning of the universe and in the singularities.
Do i believe in string i don't know because i don't know anything about it. If you could name a good book i can follow.
