Knowridge Science ReportExploding Stars, Black Holes, and the Forbidden Gap
An international team led by Monash University has uncovered evidence of a rare form of exploding star, helping to shed light on one of the most cataclysmic events in the universe. At the end of their lives, most massive stars collapse into black holes—objects with gravity so strong that not even light can escape. But some are completely destroyed in pair-instability supernova explosions. This can explain the so-named "Forbidden Gap" in black ho…
The detection of gravitational waves (GW) has revolutionized astrophysics, allowing the observation of cosmic events such as black hole mergers. From these measurements, new questions arise about the mass distribution of black holes, especially in relation to the so-called Forbidden Gap, a mass range where the presence of black holes is surprisingly scarce. Gravitational Wave Detection and Black Holes Since the first detection of gravitational w…
Gravitational waves provide indirect evidence of cataclysmic cosmic explosions
New Delhi: An international team of researchers have used data from the LIGO-Virgo-KAGRA gravitational wave observatory network to measure the properties of black holes in the forbidden range. In theory, scientists have predicted that black holes containing between 50 and 130 solar masses cannot form directly from the gravitational collapse of a massive star. Such a star would become so hot, that it would be blown away entirely, along with the …
