CERN Research Finds “The Universe Should Not Actually Exist”
According to our understanding of physics, the universe doesn't make sense.
Our Universal Paradox
With exactly equal amounts of matter and antimatter, our universe is perfectly symmetrical. While that sounds beautiful, it creates a huge problem with existential consequences. Because it possesses this fundamental symmetry, our universe shouldn’t exist at all.
According to the standard model of physics, the universe had equal amounts of antimatter and matter when it was created. The problem with that is the fact that each antimatter particle should have canceled out its corresponding matter particle, leaving nothing behind. Except they didn’t, and here we are left wondering why.
Scientists have often considered the possibility that there must be some currently unknown difference between matter and antimatter — different mass, different electric charge, different something — that allows the universe to exist.
To further explore this possibility, scientists at the European Organization for Nuclear Research (CERN) in Switzerland decided to look for a difference in magnetism. They used a method devised by researchers from Mainz University to calculate antimatter’s magnetism with never-before-seen precision, but alas, they weren’t able to find any difference.
“All of our observations find a complete symmetry between matter and antimatter, which is why the universe should not actually exist,” CERN researcher Christian Smorra said in a Mainz press release. “An asymmetry must exist here somewhere, but we simply do not understand where the difference is. What is the source of the symmetry break?”
Years of Work
While the CERN researchers weren’t able to spot any difference between matter and antimatter, the work they did is noteworthy for another reason: It resulted in our most detailed look ever at antimatter’s magnetism.
Since it’s impossible to hold antimatter in a physical container, the team devised a method involving a pair of Penning traps to contain antiprotons using magnetic and electric fields.
“The measurement of antiprotons was extremely difficult, and we had been working on it for ten years. The final breakthrough came with the revolutionary idea of performing the measurement with two particles,” Stefan Ulmer, spokesperson for the multinational BASE collaboration at CERN, said in the press release.
“This result is the culmination of many years of continuous research and development, and the successful completion of one of the most difficult measurements ever performed in a Penning trap instrument.”
As far as the universe’s existential problem is concerned, however, we’re practically back right where we started: matter and antimatter are fundamentally symmetric. We can’t spot a difference in terms of mass, electric charge, and, now, even magnetism as exhibited by protons and antiprotons. Based on everything we know, the universe shouldn’t exist.
Still, the researchers are hopeful that an answer will turn up eventually. As a next step, they plan to conduct measurements of protons and antiprotons at an even higher precision by developing more innovative methods in the next few years.
Meanwhile, a CERN collaboration called ALPHA is looking at fundamental symmetries between hydrogen and antihydrogen atoms, so perhaps one of these research groups will find something that contradicts the fact that our universe shouldn’t exist.
