String Theory

          Here's an  engrossing short video on String Theory by theoretical physicist Michio Kaku. It's a new theory (not so new because it was first studied in the late 1960s) of everything, which challenges Einstein's vision of the Universe as a constantly widening bubble with some insects stuck to it. According to that approach we live in a macrocosm of floating bubbles. When they collide or split in half they can create different universes. It is said to be the origin of the Big Bang. Scientists wonder whether one day we will be able to escape our bubble and find ourselves between universes and penetrate to some parallel universe. Of course a huge amount of energy is necessary only to consider that option, it would be connected with time travelling as well. The professor claims that sooner or later the intelligent life will perish due to the cooling and spreading of this Universe. The only solution to that threat would be to find some other bubble. It all looks like science-fiction, but String Theory is very real and backed up by sets of equations and the greatest minds of our times.I encourage you to read Kaku's books, "Hyperspace" is the one that I enjoyed the most.
