If you think we have problems now, just wait a few billion years, when the accelerating expansion of the Universe triggers an energy crisis of cosmological proportions. Sounds grim, but as a new paper points out, an advanced civilization faced with doom won’t have to go gently into that good night—there may very well…
Scientists haven’t conclusively spotted any new particles since the Higgs boson, and that’s got some people worried—there are a ton of other physics puzzles remaining, many of which would require the presence of a new particle to resolve. But recently, there have been some tantalizing clues of new physics, perhaps a…
It would be silly to think we completely understand our universe, given how small the Earth is compared to the vastness of the cosmos. But from here on our tiny planet, it appears that much of the universe is missing. And I’m not just talking about dark matter. Regular stuff seems to be missing, too.
Black holes are already some of the strangest objects in the universe, and scientists sometimes dream up some pretty wild theories about their behavior. Like maybe they can accumulate dark matter particles and turn into black hole lasers, beaming radiation out into space.
Congratulations! If you believed Federal Communications Commission chair Ajit Pai’s evidence-free assertion that someone launched a cyber attack on the agency’s website in 2017, rather than crashed after comedian John Oliver directed the audience of his insanely popular show to weigh in on Pai’s crusade to kill net…
Five-sixths of the universe’s stuff seems to be missing, and we just can’t find it. It’s called “dark matter,” and scientists have gone looking for it with some of the world’s largest, most expensive experiments.
The search for dark matter—the stuff that seems to make up most of the mass in the Universe, but which is invisible to us—is loaded with new ideas, tantalizing hints, and incredibly advanced experiments. Unfortunately, none of science’s best efforts have yielded any definitive proof of dark matter’s identity.
The US Department of Energy will fund the most sensitive search yet for theorized dark matter particles. It will sit over a mile underground, in a nickel mine near the Canadian city of Sudbury, according to a release.
Strong skepticism should always accompany strong claims. One such recent claim has generated a ton of talk about a strange, fuzzy galaxy that appears to be missing its dark matter.
Scientists are turning the tuning knob on an experiment that’s essentially a radio receiver inside of a magnet. It’s been around for years, but now it might finally be sensitive enough to hear a whole new kind of particle—one that could explain the mystery of the Universe’s dark matter.
From what scientists have gathered, galaxies are nearly synonymous with dark matter. They seem to be mostly dark matter with specks of regular matter mixed in. Despite the fact that no dark matter has been directly observed with science experiments, galaxies’ strange motion is the knock-out reason why astronomers…
This past June, 500 pounds of a specially fabricated crystal buried in an Italian mountain seemed to glow just a little brighter. It wasn’t the first time, nor the last—every year, the signal seems to increase and decrease like clockwork as the Earth orbits the Sun.
Physicists would love to find hints of dark matter to explain the parts of the universe we just haven’t been able to figure out. Dark matter would neatly explain the strange behaviors of galaxies and oddly bent light in our universe. But a new paper may have snuffed out dark matter as a candidate for a mystery at the…
We know that the universe is expanding, but a strange discrepancy in just how fast that expansion is occurring continues to confound physicists—and make them wonder whether there’s some new, unexplained physics afoot.
Today, scientists announced that they’d seen evidence of a long-sought signal from the first stars. This slight change to some ambient radio waves could herald the first step in a new kind of astronomy. But maybe, just maybe, it’s also evidence of dark matter interacting with regular matter in the ancient universe.
President Donald Trump’s 2019 budget request would nix the Wide Field Infrared Survey Telescope (WFIRST), and scientists aren’t happy.
With a new, “portable” atomic clock, scientists are measuring not what time it is but changes to time itself.
It appears that the Universe is full of dark matter—around six times more of it than there is regular matter. It has obvious visible effects, like the way it bends light from distant galaxies. Despite dedicated searches, no signs of a dark matter particle explaining these effects have turned up.
Scientists thought the Milky Way and Andromeda galaxies were unique: They’ve got rings of smaller dwarf galaxies orbiting in what seems to be a synchronized fashion. But when a team of scientists recently looked at another galaxy, they realized it also seemed to shepherd a flock of dwarfs in a strange, synchronized…
Based on physicists’ measurements, most of the mass in the universe is actually taken up by dark matter. Whatever this stuff is, we can see its effects on the behavior of distant galaxies, though no experiment has detected it here on Earth. Doing so probably requires knowing how fast it moves.
