Changing the world, bit by bit
A property of positronium—an exotic atom consisting of an electron bound to its antimatter partner, a positron—differs significantly from theoretical predictions, a team of physicists reports.
Physicists set a new record by linking together a hot soup of 15 trillion atoms in a bizarre phenomenon called quantum entanglement. The finding could be a major breakthrough for creating more accurate sensors to detect ripples in space-time called gravitational waves or even the elusive dark matter thought to pervade the universe.
Atoms can arrange themselves in regular configurations thanks to the Pauli exclusion principle
Physicists from the ASACUSA (Atomic Spectroscopy And Collisions Using Slow Antiprotons) Collaboration at CERN have successfully synthesized and studied theoretically predicted but never before verified atoms of pionic helium. Their results mark the first time such spectroscopic measurements have been made on an exotic atom containing a meson.
You might be made up of nothingness, but you still matter, according to science.
This is a huge step in quantum physics.
The team used transmission electron microscopy to achieve this impressive video.
No one really knows what happens inside an atom.
