Somewhere there might be another you, standing alone on the beach of an alien planet, watching waves crash on the shore until — wait, that was a scene from Doctor Who.

A potentially transformative theoretical study links a new model of quantum gravity with the universe’s bizarrely accelerating rate of expansion

GLOC would have a view of around 70 percent of the observable universe. It could detect everything from gravitational waves to dark matter, black hole mergers and neutron stars. With no atmosphere, light pollution or noise from the ever-shifting tectonic plates to contend with as it would on Earth, its sensitivity would be unprecedented. “Our Moon is seismically much quieter than earth in the frequency ranges that are crucial for hunting black holes,” Jani told SYFY WIRE.” The natural vacuum on the lunar surface allows for a much longer interferometer at essentially no additional cost...

Giant Comet Found in Outer Solar System by Dark Energy Survey Estimated to be 100–200 kilometers across, the unusual wandering body will make its closest approach to the Sun in 2031 Dark Energy Survey/DOE/FNAL/DECam/CTIO/NOIRLab/NSF/AURA/P.

  “According to Einstein’s Theory of General Relativity, nothing can escape from the gravity of a black hole once it has passed a point of no return, known as the event horizon,” explained Niayesh Afshordi, a physics and astronomy professor at Waterloo in 2020 about echoes in gravitational wave signals that hint that the event horizon of a black hole may be more complicated than scientists currently think based on research reporting the first tentative detection of these echoes, caused by a microscopic quantum “fuzz” that surrounds newly formed black holes. Hawking Radiation  “T...
