For an experiment designed to help find evidence of other universes, it seems surprisingly modest.as Zoran Hadjibavić When you are ushered into the lab, it feels like a classroom, complete with linoleum floors, fluorescent lights, and a whiteboard with formulas scrawled on it. But here, amidst a tangle of brightly colored wires set in stainless steel chambers and a raised platform, researchers are discovering a primordial site in the vast multiverse that may have created our universe. We are trying to recreate a quantum bubble.
The idea that our universe is just one of many universes is one of the most fascinating in physics, and the idea itself is a great explanation for how the universe became what we see today. The logic seems sound enough, in the sense that it is a development of a widely accepted theory about what happened. . But as it happens, there may be no empirical evidence of its existence at all. This is where Hadjibavich’s experiment from the University of Cambridge comes into play.
Researchers believe that if potassium atoms can be cooled to extremely low temperatures and manipulated, tiny bubbles should form spontaneously, surrogate for an otherwise unobservable process that may have given rise to the new universe. I’m betting that I can get it. By studying those bubbles, we can glean new clues about how past collisions between our universe and other universes have left traces, which we can then use in astronomical data.

“The absolute dream is that there is something in the sky that we observe that confirms what we predicted in this experiment,” he says. Matt Johnson, theoretical physicist At the Perimeter Institute in Canada.
What is the multiverse?
To be honest, what…
