As Peter Woit, a theoretical mathematician at Columbia University says, string theory “is not even wrong” because it is not falsifiable –a basic tenet of all science theory. Now, Uppsala University researchers have devised yet another “new model” for the universe based on string theory – one with the added bonus they propose may solve the enigma of dark energy.
“The discovery of dark energy has greatly changed how we think about the laws of nature,” said Edward Witten, one of the world’s leading theorists at the Institute for Advanced Study in Princeton, N.J.
“You say to yourself, ‘Here I am, the only one on the planet who knows this thing. Soon the rest of the world will know, but for the moment I am the only one.” In 1969, Stanford physicist Leonard Susskind imagined the basic building blocks of the universe as invisible vibrating loops of energy. This insight would form the basis of string theory and help lead to a radical re-envisioning of how the universe began.
