Latest development in theoritical physics is the development of string theory.I am going to explain about it in detail. Cosmic strings are a remarkable idea of theoretical physics, which science fiction writers don't really seem to have caught on to. As their name suggests, they are like string, in that they have length, but a tiny cross section. Actually, they are more like rubber bands, because they are under enormous tension, something like a hundred billion billion billion tons.A cosmic string attached to the Sun would accelerate it naught to sixty, in a thirtieth of a second.Cosmic strings may sound far-fetched, and pure science fiction, but there are good scientific reasons to believed they could have formed in the very early universe, shortly after the Big Bang. Because they are under such great tension, one might have expected them to accelerate to almost the speed of light.These aren't musical strings they are really complicated.
