Is our Universe Part Of a Multiverse?- Let's Test Multiverse Theory

Let’s say our universe is a bubble. And there happens to be another universe in another bubble. Scientists have now simulated what it would appear to be if the two bubbles bounced against each other, and their effort might disclose the significant indications of crashing universes, proposing that the multiverse theory isn’t just any other bizarre rough idea, but a testable theory. Matthew Johnson from the Perimeter Institute explains in a press release “We’re trying to find out what the testable predictions of this picture would be, and then going out and looking for them. We’re now able to say that some models predict something that we should be able to see, and since we don’t in fact see it, we can rule those models out.” In order to test the multiverse theory, Johnson and co-workers abstract the simplest type of multiple universe setup, the one in which our universe characterizes one of two such bubbles. Their research prototypes what would occur if those two universes bumped into each other and what that impact might look like to astrophysicists here on Planet Earth.

Constructing a model of everything there ever was looks like a very tall order. But not so! Johnson says “Simulating the universe is easy,” Well this is because they’re working on the biggest scales, they didn't have to give or add description for every single atom, every single star, or even every galaxy, as a matter of fact, they accounted for none of them. He adds “All I need is gravity and the stuff that makes these bubbles up,” After bumping the bubbles into each other on a computer, they stick a simulated viewer in numerous places and ask what actually that viewer would see from there. For instance, two colliding bubbles would leave a disk like shape on the sky: a round bruise in the cosmic microwave background. Because the hunt for such a disk has happened to be empty up to now, scientists are capable to exclude definite collision-filled models.  The group is now trying to work out what other noticeable hints a bubble collision would leave behind. While none of those signs have been found up to now, some of them are at least conceivable to look for.


The study was issued in Journal of Cosmology and Astroparticle Physics. You can look at all the bubbles in the video below!
