Has a white hole been discovered? When was a white hole discovered? The possibility of the existence of white holes was put forward by Russian cosmologist Igor Novikov in 1964. What is the closest black hole to Earth in 2022? Located...
What is inside a white hole? A white hole is a time-reversed black hole – a region of space-time where matter spontaneously appears and explodes outwards, rather than implodes and disappears as with a black hole. White holes are essentially the...

Is there any black hole near Earth? Astronomers have discovered a black hole closer to Earth than any other previously found. It’s about ten times as massive as our sun and is located just 1,600 light-years away—rather nearby on a cosmic...
How tiny can a black hole be? Tiny in this context means something around a billionth of a billionth of the mass of the sun—a couple billion tons, or the mass of a small asteroid. A black hole of this mass...
How big is the Unicorn black hole? The Unicorn is about three times the mass of our sun – tiny for a black hole. Very few black holes of this mass have been found in the universe. This black hole is...
What is the nearest black hole to Earth? Gaia BH1, at ~10 solar masses, with an orbital period of ~180 days, and located just 1560 light-years away, now holds the record (as of 2022) for closest black hole known to our...
Which is the dangerous black hole? Messier 87’s black hole. Credit: Event Horizon Telescope collaboration et al. There is also a supermassive black hole at the centre of our galaxy, the Milky Way. It’s called Sagittarius A* and in 2022 it...
Where is the Unicorn black hole located? It is located about 1,500 light years from Earth. Scientists have discovered what may be the smallest-known black hole in the Milky Way galaxy and the closest to our solar system — an object...
How big are black holes images? They collected nearly 4 petabytes (4,000 terabytes) of data, which was too much to be sent over the Internet and had to be carried by aeroplane on hard disks. How many petabytes is the black...
