Could our galaxy actually be inside a black hole? New research seems to suggest this possibility. NASA’s James Webb Telescope discovered that the rotation of the galaxies goes against what scientists previously thought about the universe. The findings have revealed new insights about deep space.
Not so random
Data from NASA‘s James Webb Space Telescope Advanced Deep Extragalactic Survey found that the majority of galaxies rotate in the same direction, according to a journal article in Monthly Notices of the Royal Astronomical Society. After analyzing 263 galaxies, two-thirds were found to rotate clockwise, while approximately one-third of them rotated counterclockwise.
The Milky Way rotates counterclockwise, putting it in the minority. These findings are surprising because if the universe is random, as previously thought, “there should be an approximately equal amount of galaxies rotating in both direction[s],” said Popular Mechanics.
One explanation for this phenomenon is that the “universe was born rotating,” Lior Shamir, a computer science professor at Kansas State University and author of the study, said in a statement. This explanation “agrees with theories such as black hole cosmology, which postulates that the entire universe is the interior of a black hole.” However, if the universe was born rotating, “it means that the existing theories about the cosmos are incomplete.”
Black hole cosmology “suggests that the Milky Way and every other observable galaxy in our universe is contained within a black hole that formed in another, much larger, universe,” said The Independent. The theory “challenges many fundamental models of the cosmos, including the idea that the Big Bang was the beginning of the universe.” The study’s data also opens the door to the idea that each black hole is a door to another universe and that we exist in a multiverse.
Black hole in the wall
The idea that the universe is in the interior of a black hole is decades old. It posits that the “‘event horizon’ (the boundary from within which nothing can escape a black hole, not even light) is also the horizon of the visible universe,” said Space.com. In turn, “each and every black hole in our universe could be the doorway to another ‘baby universe,'” and “these universes would be unobservable to us because they are also behind an event horizon.”
This would also explain why there seem to be more rotations in one direction. “It would be fascinating if our universe had a preferred axis,” Nikodem Poplawski, a theoretical physicist at the University of New Haven, said to Space.com. “Such an axis could be naturally explained by the theory that our universe was born on the other side of the event horizon of a black hole existing in some parent universe.”
The black hole theory is only one potential explanation for why most galaxies appear to rotate clockwise. The other is that the Milky Way’s rotational velocity is affecting the measurements. “If that is indeed the case, we will need to recalibrate our distance measurements for the deep universe,” said Shamir. The “recalibration of distance measurements can also explain several other unsolved questions in cosmology.”
