What are black holes? Everything you need to know about the darkest objects in the universe

Black holes are regions of space where the gravitational pull is so strong that nothing — not even light — can escape. Rather than empty space, black holes are chock full of matter that gets squeezed into a teensy space.  Who discovered black holes? Physicist Karl Schwarzschild accidentally discovered black holes in 1916, when he was figuring out a particular solution to Einstein's general theory of relativity. He was trying to find the solution to the gravitational pull of a single, solitary, symmetric ball of matter — such as the sun at the center of our solar system. But that solution contained a peculiar feature: the theory behaved strangely at a specific radius, known today as the Schwarzschild radius. It was later realized why this radius was so special. If you compressed the mass of an object into a space smaller than that radius, its gravitational pull would overwhelm every known force and nothing could escape. Early physicists assumed that this situ...

1,000 TRILUMINOUSLY brighter than a Sun: A supermassive black hole is “squeezing like a toothpaste tube” a star

A star being squeezed like a toothpaste tube’ by a supermassive black hole generated a mysteriously brilliant flash that emitted more light than 1,000 TRILLION suns, according to research. According to research, a mysteriously brilliant light in the sky was created by a supermassive black hole “squeezing like a toothpaste tube” a faraway star. When astronomers at the Zwicky Transient Facility in California discovered a flash in February that produced more light than a trillion suns, they were perplexed. A tidal disruption event (TDE), in which a star Travel s a bit too near to a black hole and is torn apart by its gravitational pull, is now the cause of the light, according to the research team. It is the brightest TDE ever seen from Earth and is being termed one of the most violent occurrences in the cosmos, with temperatures exceeding 54,000°F (30,000°C). The event, AT2022cmc, was the furthest TDE ever discovered and took place more than eight billion lig...
