Multiple universes arise from the
idea that at the beginning there was a vacuum
scattered by energy, called dark energy, vacuum energy, an inflation field
TORONTO: Our universe could only be one in the sea of an infinite number of other universes, say scientists who hope that new experiments will help them prove the theory of the multiverse.
Experts at the Perimeter Institute of Theoretical Physics in Canada say that the theory of multiple universes stems from the idea that at the beginning there was a vacuum scattered by energy, called dark energy, vacuum energy, an inflation field, or a Higgs field.
“As water in the pot, this boiling energy began to evaporate and thus formed bubbles,” scientists explain. Each bubble contained a vacuum in itself, whose energy, although lower, led to its expansion. Some bubbles inevitably collided, which eventually led to the formation of secondary bubbles, they said.
Each of these bubbles was one universe. And our universe is just one bubble in the sparkling sea of countless other bubbles, i.e. of the universe, according to Canadian researchers.
The theory was based on the idea of cosmic inflation, which implies that the universe accelerated rapidly after the Big Bang. Although widely accepted, this theory of the origin of the universe has never been confirmed, which scientists believe can now be done.
“We are trying to find out what could be the verifiable predictions of this image so that we can then begin looking for them,” Matthew Johnson told the Perimeter Institute, specifying that he and his colleagues are studying rare cases in which our universe could collide with Someone else.
“We are doing a simulation of the whole universe. We start from a mulberry-bubble with two bladders, we collide bubbles on a computer to see what will happen, then we set up a virtual observer in various places and we wonder what he could see from there,” he added.
The program has already reached the extent to which some multiverse models can be excluded. For example, a collision of two universes would leave what Johnson calls “a disk in the sky,” a round trace in cosmic microwave background radiation.
Since the search for such a disc has not yielded any results yet, it can be concluded that some models that presuppose a collision of the universe are less likely. This is the first time, scientists point out, that a direct quantitative set of predictions about the visible collisions of the collision of the universe is drawn.
