Our universe could be inside black hole, suggests James Webb telescope – Interesting Engineering

Scientists find new evidence suggesting that our universe has been rotating since birth inside a black hole.a day ago2 days ago2 days ago2 days ago2 days ago2 days ago2 days ago2 days ago3 days ago3 days ago40 minutes agoan hour agoan hour ago2 hours ago2 hours ago2 hours ago5 hours ago5 hours ago6 hours ago6 hours agoRupendra BrahambhattAn illustration depicting a black hole.tose/iStockOver a century ago, a German physicist named Karl Schwarzschild mathematically described what we now recognize as a black hole using equations. He laid the foundation for black hole cosmology, which is also called the Schwarzschild cosmology.Many years later, in the early 1970s, two scientists, Raj Kumar Pathria and I.J. Good, built upon Schwarzschild’s work and proposed that the Schwarzschild radius—which we now call the event horizon (the boundary of a black hole beyond which nothing can escape) might also act as the boundary of our universe.Basically, what they meant is that our universe exists inside a black hole that itself resides within a larger universe — sounds insane, right?Well, here’s something even more insane: A new study based on the findings of the James Webb Telescope suggests that Pathria and Good were right.Cosmologists generally assume that the universe, on large scales, is homogeneous and isotropic. Homogeneity means that the universe has uniform properties throughout, while isotropy indicates that it appears the same in all directions from any given point.However, the study authors found something that challenges this commonly believed assumption. They examined 263 galaxies captured by the James Webb Space Telescope Advanced Deep Extragalactic Survey (JADES), a research project that uses the ultra-powerful telescope to study the oldest and most distant galaxies in our universe.If our universe is truly isotropic, there should be no inherent bias in the rotational directions, which means that almost equal numbers of galaxies should rotate clockwise (50 percent) and anticlockwise (50 percent) — but this isn’t the case.The researchers discovered that nearly one-third of the galaxies in the survey rotated anticlockwise, and over two-thirds showed clockwise movement. “The analysis of the galaxies was done by quantitative analysis of their shapes, but the difference is so obvious that any person looking at the image can see it. There is no need for special skills or knowledge to see that the numbers are different. With the power of the James Webb Space Telescope, anyone can see it,” Lior Shamir, study author and professor at Kansas State University, said.This finding suggests that our universe has a favored galactic spin direction — but why?According to the researchers, the difference in rotational directions suggests that the universe has been spinning since the time of its existence. It may have inherited its spin from a black hole inside which it resides.“One explanation is that the universe was born rotating. That explanation agrees with theories such as black hole cosmology, which postulates that the entire universe is the interior of a black hole. But if the universe was indeed born rotating, it means that the existing theories about the cosmos are incomplete.” Shamir said.However, there’s another factor that could be at play here. When an object moves away or towards you, there’s a change in the frequency of sound or light emitted by the object. This phenomenon is called the Doppler shift.So when Earth rotates around the center of the Milky Way, it moves in a specific direction. Because of the Doppler shift, if a galaxy is rotating opposite to Earth’s movement, the light it emits gets slightly compressed. This makes it appear brighter than galaxies moving in the same direction as Earth. This effect could explain why telescopes detect more galaxies rotating opposite to Earth’s motion than expected.“If that is indeed the case, we will need to re-calibrate our distance measurements for the deep universe. The re-calibration of distance measurements can also explain several other unsolved questions in cosmology, such as the differences in the expansion rates of the universe and the large galaxies that, according to the existing distance measurements, are expected to be older than the universe itself,” Shamir concluded.The study is published in the journal Monthly Notices of the Royal Astronomical Society.Rupendra Brahambhatt Rupendra Brahambhatt is an experienced writer, researcher, journalist, and filmmaker.
