Earth and our entire Milky Way galaxy may sit inside a mysterious giant hole which makes the cosmos expand faster here than in neighboring regions of the universe, astronomers say. Their theory is a potential solution to the ‘Hubble tension’ and could help confirm the true age of our universe, which is estimated to be around 13.8 billion years old. …

Discoveries keep pouring out of the James Webb Space Telescope (JWST). Researchers observed an unusual cluster, which they dubbed the Infinity Galaxy. It appears to support a leading theory on how some supermassive black holes form. Although “Infinity Galaxy” sounds like a place Thanos would hang out, it merely describes its appearance. Two compact, red nuclei, each surrounded by a …

Last April, geologists conducting routine maintenance at temperature logging stations in Yellowstone National Park’s Norris Geyser Basin found something unexpected: a previously undocumented thermal pool of blue water. The newly identified pool, found in the Porcelain Basin subbasin, is about 13 feet (4 meters) wide, its idyllic blue water is around 109 degrees Fahrenheit (43 degrees Celsius), and the water’s …

Sign up for the Starts With a Bang newsletter Travel the universe with Dr. Ethan Siegel as he answers the biggest questions of all. If you want to detect a gravitational wave, you have to design something extraordinary. Gravitational waves are ripples in spacetime — distortions in the very fabric of spacetime itself — that propagate at the speed of …

Scientists have detected the biggest black hole merger ever known — a gigantic collision from two massive space-time ruptures spiraling into each other — and it could hold evidence of the most elusive type of black hole in the universe. The merger, which happened on the outskirts of our Milky Way galaxy, produced a black hole roughly 225 times more …

The LIGO-Virgo-KAGRA (LVK) Collaboration has detected the merger of the most massive black holes ever observed with gravitational waves using the US National Science Foundation (NSF)-funded LIGO observatories. The powerful merger produced a final black hole approximately 225 times the mass of our Sun. The signal, designated GW231123, was detected during the fourth observing run of the LVK network on …

Scientists have detected the most massive merger of black holes ever. This titanic collision, “heard” in ripples in spacetime called gravitational waves, involves black holes so massive that it could challenge current models of the universe. The merger was detected by the gravitational wave detector network LIGO-Virgo-KAGRA (LVK) on Nov. 23, 2023, during the fourth observing run of these three …

Gravitational waves—ripples in space-time caused by violent cosmic events—travel at the speed of light in every direction, eventually fading out like ripples in water. But some events are so destructive and extreme that they create disturbances in spacetime more like powerful waves than small ripples, with enough energy to reach our own detectors here on Earth.  Today, the LIGO Collaboration …

Image by Yihan Wang via Pexels According to The Conversation, a new study published in Physical Review D challenges the common idea that the Big Bang was the start of everything. Instead, researchers suggest it might have been a rebound—a bounce—after a huge gravitational collapse forming a black hole. This “black hole universe” idea uses everyday physics to rethink cosmic …
