The Ultimate Limit of Matter: Neutron Stars & Black Holes #shorts

[00:00:00]What's the absolute limit [music] before a dead star becomes a cosmic point of no return?

[00:00:04]Neutron stars are the universe's ultimate pressure cookers.

[00:00:08]When massive stars explode, their cores collapse into city-sized [music] objects so dense that a teaspoon would weigh a billion tons on Earth. But there's a limit to how massive these stellar corpses can become. Enter the Tolman-Oppenheimer-Volkoff [music] limit, discovered in 1939.

[00:00:24]This cosmic [music] boundary sits around two to 2.5 times our sun's mass.

[00:00:28]Beyond this [music] threshold, not even degeneracy pressure can fight gravity's crushing grip. The star collapses [music] further, vanishing into a black hole.

[00:00:37]Think of it like stacking books.

[00:00:39]Eventually, [music] the bottom ones can't support any more weight and collapse. For neutron stars, [music] that breaking point happens when they're roughly twice as massive as our sun, but only 12 miles across.

[00:00:50]Recent gravitational wave detections [music] from merging neutron stars are helping scientists pinpoint this exact limit. Could we be witnessing the birth of black holes in [music] real time?
