Wormholes Could Help Solve an Infamous Black Hole Paradox, Says Fun New Paper

What happens to information after it has passed beyond the event horizon of a black hole? There have been suggestions that the geometry of wormholes might help us solve this vexing problem – but the math has been tricky, to say the least.   In a new paper, an international team of physicists has found … Read more

Atomic clock experiment shows Einstein’s general relativity is right

Physicists have measured time dilation on the smallest scale ever using an atomic clock made of thousands of ultracold atoms formed into a stack of pancake-shaped blobs Physics 16 February 2022 By Alex Wilkins Time dilation has been measured inside a tiny atomic clock Jacobson/NIST The world’s most precise atomic clock has confirmed that the … Read more

Einstein’s theory of general relativity

General relativity is physicist Albert Einstein‘s understanding of how gravity affects the fabric of space-time. The theory, which Einstein published in 1915, expanded the theory of special relativity that he had published 10 years earlier. Special relativity argued that space and time are inextricably connected, but that theory didn’t acknowledge the existence of gravity. Einstein … Read more

Einstein’s theory of general relativity passes one of its toughest tests yet

General relativity has withstood perhaps its toughest challenge to date. The theory, which Albert Einstein published in 1916, revolutionized our understanding of physics and the cosmos. It explains gravity as a consequence of space-time’s flexibility: Massive objects warp space-time, creating depressions around which other bodies orbit. Scientists have put general relativity to the test repeatedly … Read more

16-Year Study of Extreme Stars Has Once Again Proved Einstein Is Still Right

Two pulsars locked in close binary orbit have once again validated predictions made by Einstein’s theory of general relativity. Over 16 years, an international team of astronomers has observed the pulsar pair, named PSR J0737−3039A/B, finding that the relativistic effects can be measured in the timing of their pulses – just as predicted and expected. … Read more
