Physicists Designed an Experiment to Turn Light Into Matter
Plasma could be wrangled to collide photons and yield matter, according to physicists who ran simulations to explore the practical applications of a world-famous equation. The equation at work here is Einstein’s E = mc^2, which establishes a relationship between energy and mass; specifically, the equation holds that energy and mass are equivalent when the…

Physicists Laser-Cool Antimatter to Near Absolute Zero
For a little more than a week in July 2018, a team of physicists at CERN tried a new technique to slow down antimatter particles zipping around at breakneck speeds. Those 10 days of observation were the culmination of 10 years of development in an international collaboration called ALPHA, which oversaw the design and construction…
