Big Questions: Missing Antimatter

   

Big Questions:  Missing Antimatter





Δημοσιεύτηκε στις 27 Αυγ 2013
Einstein's equation E = mc2 is often
said to mean that energy can be converted into matter. More
accurately, energy can be converted to matter and antimatter.

During
the first moments of the Big Bang, the universe was smaller, hotter and
energy was everywhere. As the universe expanded and cooled, the energy
converted into matter and antimatter. According to our best
understanding, these two substances should have been created in equal
quantities. However when we look out into the cosmos we see only matter
and no antimatter.

The absence of antimatter is one of the Big
Mysteries of modern physics. In this video, Fermilab's Dr. Don Lincoln
explains the problem, although doesn't answer it. The answer, as in all
Big Mysteries, is still unknown and one of the leading research topics
of contemporary science.
