New Delhi : In a recent breakthrough research, CERN Scientists have revealed that the universe which we know it
should not exist.The findings from the BASE (Baryon Antibaryon Symmetry Experiment) are published in
the journal Nature.
The CERN scientists have performed the most precise experiment on antiprotons in which they have found
a symmetry in nature that they say just shouldn’t be possible.
The scientists have raised serious concern about the universe that the first matter formed after the
Big Bang. Because particles and antiparticles annihilate one another when they come into contact, if
there were exactly equal measures of both, the universe wouldn’t exist—at least not in the form we see
it today. As such, there must be an imbalance between particles and antiparticles, even if it is only
by the tiniest fraction.
“All of our observations find a complete symmetry between matter and antimatter, which is why the
universe should not actually exist,” first author Christian Smorra, from Japan’s RIKEN institute, said
in a statement.
In the study, researchers used antiprotons that had been isolated in 2015. The antiprotons were
measured using the interaction of two traps that use electrical and magnetic fields to capture them.
The team was able to measure the magnetic force of the antiproton to a level that is 350 times more
precise than ever before.
If there was an imbalance between protons and antiprotons, this level of precision would be the best
bet for finding it. “At its core, the question is whether the antiproton has the same magnetism as a
proton,” said Stefan Ulmer, spokesperson of the BASE group. “This is the riddle we need to solve.”
“The measurement of antiprotons was extremely difficult and we had been working on it for 10 years. The
final breakthrough came with the revolutionary idea of performing the measurement with two particles.”
After finding no asymmetry between particles and antiparticles, the researchers will now work to
develop even higher-precision measurements of protons and antiprotons to improve on the latest
findings. “An asymmetry must exist here somewhere but we simply do not understand where the difference
is. What is the source of the symmetry break?” Smorra said.–
