Supernovae are already some of the brightest explosions in the universe—but there’s more mysterious type, called superluminous supernovae, that can shine a hundred times brighter than the usual ones. And on August 22, 2016, astronomers spotted one whose light traveled over 10 billion years to reach us.

The discovery of the event, called DES16C2nm, was exciting enough on its own since it would normally have been invisible to telescopes if not for the fact that the universe is expanding, thus stretching the light from the explosion into wavelengths we can see from Earth. More generally, these flashes can tell the story of our universe, like what kinds of stuff lives between stars in distant galaxies, and other quirks of the cosmos.

“The more distant supernovae we see, the more information we get on those stars.” one of the study’s authors, Charlotte Angus from the University of Southampton in the United Kingdom, told Gizmodo.

Weird connections through space-time might make reality real, giving us a promising new route to a theory of everything.

Using a laser beam one quadrillion times brighter than the Sun, physicists have stopped electrons travelling at near-light speeds for the first time. The experiment produced a quantum mechanical phenomenon that was previously only thought to occur around black holes and quasars.

Maybe gravity acts differently, or particles come in different shapes and sizes. Could life still exist in any of these bubbles? A team of researchers at the University of Michigan asked these questions but took things a step further. They removed one of the four fundamental forces of nature, the weak nuclear force, from their hypothetical universes. And according to their calculations, these alter…
