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 …

Jennifer Love Hewitt looked radiant at the red carpet premiere of the I Know What You Did Last Summer reboot. Hewitt, 46, flaunted her curves in a black, beaded dress on Monday, July 14, accessorizing the look with glittery black heels and a ring on nearly every finger. The redhead kept her makeup tastefully dramatic with a smoky eye and …

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 …

Physicists with the LIGO/Virgo/KAGRA collaboration have detected the gravitational wave signal (dubbed GW231123) of the most massive merger between two black holes yet observed, resulting in a new black hole that is 225 times more massive than our Sun. The results were presented at the Edoardo Amaldi Conference on Gravitational Waves in Glasgow, Scotland. The LIGO/Virgo/KAGRA collaboration searches the universe …

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 …

The era of Pokémon Scarlet & Violet is about to draw to a close. While the mainline video game series may have broken from its traditional three-year cycle, the trading card game has not, and the run of Gen-IX-led packs comes to an end with this month’s release of Black Bolt and White Flare. Oddly, it’s a celebration of the …

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 …

Sunday, July 13, 2025 by Lina Fisher In 2022, Austin had just broken into the top 10 largest cities in America. It was the fastest-growing large metro area in the country, and had held that title for 12 years. Now, Austin has dipped to the 13th largest city, and the fourth fastest-growing region in the country. What happened in the …

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 …
