But should one of these quantum numbers be very slightly different between matter and antimatter particles, it might explain why matter became the dominant вЂњstuffвЂќ of the universe. a beautiful example of symmetry in the quantum world.

Protons have anti-protons, electrons have positrons, neutrinos have anti-neutrinos etc. This physics conundrum focuses on the idea that all particles have their antimatter twin with the same quantum numbers, only the exact opposite. It is predicted that equal amounts of matter and antimatter were produced in the primordial universe (a basic prediction by the Standard Model of physics), but if thatвЂ™s the case, all matter in the universe should have been annihilated when it came into contact with its antimatter counterpart - a Big Bang followed by a big disappointment. Evidently, matter won - because there are galaxies, stars, planets, you, me, hamsters, long walks on sandy beaches and beer - but how matter won is one of the biggest mysteries hanging over physics. The universe is the embodiment of an epic battle between matter and antimatter that occurred immediately after the Big Bang, 13.82 billion years ago.

The universe shouldnвЂ™t exist, according to new ultra-precise measurements of anti-protons.Д«ut the fact that IвЂ™m typing this article and youвЂ™re reading it, however, suggests that we are here, so something must be awry with our understanding of the physics the universe is governed by. Because it looks cool (NASA, ESA, Hubble Heritage Team)

Does antimatter exist
