Theory of Relativity drives plan for Moon standard time

Thanks to Albert Einstein, the US Government wants to establish an official time zone for the Moon. It has less to do with jet lag and more to do with how gravity affects time and can throw a lot of very precise technologies seriously off track.Continu… Continue reading Theory of Relativity drives plan for Moon standard time

Our galaxy’s black hole spins so fast it warps spacetime into a football

A supermassive monster lurks at the center of our galaxy, and astronomers have now discovered that it’s spinning so fast it’s warping the very fabric of spacetime into a football shape.Continue ReadingCategory: Space, ScienceTags: Astronomy, Black hole… Continue reading Our galaxy’s black hole spins so fast it warps spacetime into a football

Hunting spacetime fluctuations could unite Einstein and quantum physics

A unified Theory Of Everything is the holy grail of physics, but gravity refuses to play ball. Now, a newly proposed theory attempts to unify Einstein’s theory of gravity with quantum mechanics – and importantly, outlines a way to test it experimentall… Continue reading Hunting spacetime fluctuations could unite Einstein and quantum physics

Cosmic clocks show that time passed more slowly in the ancient universe

Scientists using quasars as cosmic clocks have observed that when the universe was just a billion years old, time ran five times slower, helping to confirm Einstein’s general theory of relativity and the expansion of the universe.Continue ReadingCatego… Continue reading Cosmic clocks show that time passed more slowly in the ancient universe

“Quantum gravity” clues could be hiding in the songs of black holes

Of the four fundamental forces of physics, gravity is the one we’re most familiar with in everyday life, but it’s also the only one that can’t currently be explained by quantum physics. Now scientists have outlined a plan to look for signs of quantum g… Continue reading “Quantum gravity” clues could be hiding in the songs of black holes

Einstein paper heads for auction tonight – a bargain in the offing?

A six-page autograph manuscript by Albert Einstein entitled “The Essence of the Theory of Relativity” is being auctioned tonight and scientific voyeurs might care to watch the fun as the heavy hitters come out to play. The auction will be live on the i… Continue reading Einstein paper heads for auction tonight – a bargain in the offing?
