“The Unknown Question” –The End of Spacetime

Wormhole in Spacetime


Theoretical physicist Nima Arkani-Hamed, a professor at the Institute for Advanced Study (IAS) in Princeton, N.J., takes us past the edge, beyond Einstein, beyond space-time and quantum mechanics and the tropes of 20th-century physics, to a spectacular new vision of the cosmos. (more…)

“No Symmetry” –The Mystery of Gravity at the Quantum Level

Gravity Affecting a Spiral Galaxy


“Many physicists believe that there must a beautiful set of laws in Nature and that one way to quantify the beauty is by symmetry. Some of the symmetries may be hidden in our world, but they should manifest themselves if we look at Nature at a more fundamental level. We showed that this expectation is wrong once we take into account the gravity,” said Caltech’s Hirosi Ooguri, Director of the Kavli Institute for the Physics and Mathematics of the Universe, about a new study that has found that, when gravity is combined with quantum mechanics, symmetry is not possible.
