We can’t have bulk observables in quantum gravity, because once the metric starts to fluctuate, the points move around, and we no longer know what we mean by the correlation function at two points. So that’s why we’re forced to talk about boundary observables.

Stephen Hawking: "Găurile negre sunt portaluri spre alt univers"

Stephen Hawking: “Găurile negre sunt portaluri spre alt univers”

Stephen Hawking e cunoscut pentru teoriile intrigante pe care le formulează, mai ales în legătură cu găurile negre.

Celebrul fizician susține teoria potrivit căreia universul nostru nu este unic, existând numeroase alte universuri. Dar lucrurile nu se opresc aici, pentru că „găurile negre sunt pasaje spre alte astfel de universuri”, susține Hawking într-un articol scris împreună cu Andrew…

Stephen Hawkings New Theory About Black Holes Will Blow Your Mind

Stephen Hawkings New Theory About Black Holes Will Blow Your Mind

Stephen Hawking unveiled a new theory that could tremendously increase the current understanding of black holes and how they form. Einstein’s theory of relativity states black holes are so dense, no light or matter can escape them. This would make it impossible to learn anything about their pasts, according to NBC News. In the 1970s, however, Stephen Hawking proposed an idea:Black holes leak…

Experimentalist VS Theorist on Einstein's General Theory of Relativity

Einstein's theories provided elegant explanations for existing phenomena—but he didn't quite hit the big time until experiments during a solar eclipse verified some of the predictions of his general theory of relativity. In this clip from the 2015 World Science Festival program "Reality Since Einstein," physicists Andrew Strominger and Steven Weinberg discuss the historic tension between theorists and experimentalists in science with moderator and fellow physicist Brian Greene.
