A recent gravitational wave detection shed some light on a previously 'forbidden' black hole mass range. The discovery has implications for astrophysics and our understanding of the evolution of compact objects and the fate of stars.

A few minutes ago, somewhere in the universe, two black holes collided, and it sent shockwaves throughout space and time but this isn't a scene from Interstellar. It happened nearly 2 billion lightyears away, and the resultant gravitational wave just reached Earth, giving scientists a glimpse into this cataclysmic event and offering valuable insights into the most extreme aspects of the universe.

Almost everything we've learned about black holes has been derived from gravitational waves wobbles in the fabric of space-time caused by the acceleration of massive objects, like when two black holes orbit each other. But this latest discovery is particularly intriguing as one of the black holes involved has a mass that's right at or just above the so-called pair instability mass gap. This is a tricky concept to grasp, so let's take a step back.

All gravity waves and black holes involve extremely huge masses and enormous gravitational forces. The pair instability mass gap is a theoretical idea which suggests that above a certain threshold, gravity prevents a star from collapsing into a black hole as it creates a pair of heavy neutron stars. It's like a cosmic barrier that can halt the formation of black holes. This new discovery has blown the door open to exploring this 'forbidden' black hole mass range and may shift our understanding of how black holes can form.

On top of that, the collision of these two black holes produced the distinctively loud rumble of a gravitational wave, which is a bit like a cosmic boombox. This marks the loudest gravitational wave signal we've detected so far, and it helped to confirm that the heavier black hole was at or above the pair instability mass gap something we never could have predicted.

Now, astrophysicists are excited to analyze these new findings and uncover more about the universe we live in. This discovery is a testament to the power of gravitational wave astronomy in giving us a window into the otherwise unseen universe.

This is only the beginning, as some researchers predict that this barrier could be broken in the near future, which may provide clues to even more exotic phenomena. It's a thrilling time for those studying the universe's most elusive and mysterious objects.
