Universe or universe (universe) consists of hundreds of billions of galaxies with an almost incalculable number of stars, spanning tens of billions of light years. According to the multiverse theory, multiuniverses or multiple universes suggest that there may be other universes in the sky.
“It could be that our universe is just one member of a much larger and more multiverse universe,” wrote Paul M Sutter, professor of astrophysics research at the Institute for Advanced Computational Science at Stony Brook University and the Flatiron Institute in New York City. on the page Live Science Tuesday (24/8) edition.
The concept of the multiverse appears in several fields of physics (and philosophy), but the most prominent example comes from something called the inflation theory that US physicist Alan Guth put forward in 1980. Inflation theory describes a hypothetical event that occurred when the universe was very young less than a year old. second.
According to the National Aeronautics and Space Administration (NASA), after the Big Bang (Big Bang), in a very short time, the universe underwent a period of rapid expansion, expanding to become larger than its previous size,
“Inflation of our universe is thought to have ended about 14 billion years ago. However, inflation did not end at the same time everywhere,” said Heling Deng, a cosmologist at Arizona State University and an expert in multiverse theory. “It is possible that when inflation ends in some regions, inflation continues in other regions,” he added.
Inflation in this universe has ended but there may be other parts of the region that are more distant still continuing even today. Individual universes can instantly expand and expand, creating an infinite sea of eternal inflation and producing many other individual universes.
In this scenario of perpetual inflation, each universe would emerge with its own laws of physics, its own set of particles, its own set of forces, and its own value of its own fundamental constant.
“This may explain why our universe has those properties, especially properties that are difficult to explain with basic physics, such as dark matter or the cosmological constant,” said Deng. “If there was a multiverse, then we would have random cosmological constants in different universes,” he added.
The greatest evidence for a multiuniverse is that life exists, especially intelligent life capable of cosmological observations. “Certain aspects of our universe appear special and important to support life, such as the longevity of stars, the abundance of carbon, the availability of light for photosynthesis, and the stability of complex atomic nuclei,” said McCullen Sandora, research scientist at the Blue Marble Space Institute of Science. .
Find the Evidence
Many scientists have tried to find more physical and strong evidence to prove the multiverse theory. For example, if there was a neighboring universe long ago, it might have collided with the current universe. Moreover other universes are supposed to create detectable traces.
The traces could be distortions in the cosmic microwave background, that is, light left over from when the universe was a million times smaller than it is today, in the strange properties of galaxies in the direction of the collision, according to the blog. Early Universe published by University College London. But all these searches were in vain, so the multiverse remains a hypothesis.
Deng himself is looking for evidence of a multiverse by looking for a special type of black hole that could be an artifact of this piece of the universe that split into its own universe through a process called quantum tunneling.
If some of these regions of the universe split in such a way, they would leave “bubbles” in the universe that would turn into unique black holes, which may still exist today. “The detection of this potential black hole can then indicate the existence of the multiverse,” said Deng. there is / I-1
