What’s the Latest? University of Cambridge physicists have discovered a theoretical foundation for the existence of wormholes, which are tubes that connect two different points in space-time. If a piece of information or a physical object could travel through the … Read More
Signals buried deep in gravitational wave observatories’ data point to a collision of two black holes that were clearly born in different places. Almost all of the spacetime ripples observed by experiments such as the Laser Interferometer Gravitational-Wave Observatory, or … Read More
Long after the last stars fade, black holes will herald the end of the Universe with a spectacular show of fireworks. Black holes are areas of space-time where gravity rules supreme: A black hole’s gravitational pull is so strong that … Read More
