Physicists don’t know where most of the universe’s apparent mass has gone, and attempts to find it have so far failed. But a proposed particle born out of the universe’s chaotic first moments may provide a candidate and a reasonable way to look for it.
Pioneering physicist Murray Gell-Mann has passed away at the age of 89. Among his many scientific contributions, the Nobel laureate will be remembered for bringing order to the chaotic field of particle physics, and for coining the term “quark”—a fundamental building block of matter.
In September, the Chinese Academy of Sciences president Chunli Bai, and President Anton Zeilinger of the Austria Academy of Sciences in Vienna, made the first quantum-secured video call. But when will you get to take part in this? Will there ever be a secure quantum Slack at your workplace?
