An artist's illustration of the black hole at the heart of a quasar in the distant universe. The biggest black hole known to exist lives in the nearby galaxy M87. It's 2,000 times bigger than the Milky Way's supermassive black hole.
Parallel universes - Black Hole connected to a theoretical White Hole. - If the theoretical science is correct, there are an infinite number of universes with same situations and different outcomes, do you believe?
In August of 2007, astronomers located a gigantic hole in the universe. This empty space, stretching nearly a billion light-years across, is devoid of any matter such as galaxies, stars, and gas, and neither does it contain the strange and mysterious dark matter, which can be detected but not seen. The large void in the Constellation Eridanus appears to be improbable given current cosmological models. A radical and controversial theory proposes that it is a "universe-in-mass black hole"
A recent study suggests that each black hole contains another entire universe! According to the new equations, the matter black holes absorb and seemingly destroy is actually expelled and becomes the building blocks for galaxies, stars, and planets in another reality. Essentially, every black hole contains a smaller alternate universe. And our universe might just exist inside a black hole of a galaxy in a much larger universe.
Is Our Universe Inside Another Larger Universe? Theoretical physicist Nikodem Poplawski from Indiana University has proposed that perhaps our universe could be located within the interior of a wormhole which itself is part of a black hole that lies within a much larger universe.
