Trying to Understand the Size of This New Space Discovery Will Short-Circuit Your Brain

Light’s speed limit means that looking into the distance is the same as looking into the past: The farther incoming light travels, the older it is. Out in the distance, scientists have spotted a truly enormous, ancient “proto-supercluster,” dubbed Hyperion, which could help explain how the universe forms some of its…

There's Now a Proven Way for Quantum Computers to Beat Classical Computers—With a Catch

Entrepreneurs and physicists are pursuing a new kind of computer—one based on the physics of the subatomic particles—that promises to revolutionize various fields. Presumably, such a quantum computer should offer some advantage over the classical computers we already use, right? The trouble is, it’s unclear what tasks…

Scientists Release Result from 'Astonishing' Feat of Creating and Testing Quantum Gas in Space

Last year, graduate student Dennis Becker watched from a safehouse as the MAIUS-1's sounding rocket took off from a launch facility in the Swedish Arctic. But even after repeated delays from snow and wind, he wouldn’t know for a few days whether the rocket’s payload survived. When the ambitious experiment dropped back…
