For those still holding out hope that antimatter levitates rather than falls in a gravitational field, like normal matter, the results of a new experiment are a dose of cold reality.

Currently, one of the major goals in ultracold science is to cool antihydrogen atoms to as close to absolute zero as possible. Ultracold antihydrogen would pave the way toward ultraprecise antimatter experiments that could ...
When the Universe arose some 13.7 billion years ago, the Big Bang generated matter and antimatter particles in mirroring pairs. So the reigning physics theory goes.
