For the second time this year, physicists at the Advanced Laser Interferometer Gravitational Waves Observatory (LIGO) are giddy with excitement. They’ve just confirmed the second detection of gravitational waves, ripples in the fabric of spacetime proposed by Albert Einstein a century ago. It seems we’ve officially…
Add this to the list of existential fears that keep you up at night: the universe appears to be expanding faster than we thought. A lot faster.
In need of a quick refresher course on, well, the science of pretty much everything? Here’s a cheeky, irreverent summation of the universe in just four minutes from Exub1a, YouTube purveyor of “spacey stuff and existential angst.”
Earlier this year, scientists confirmed the presence of gravitational waves, a cosmological feature first predicted by Albert Einstein. In recognition of this remarkable achievement, the scientists involved in the study have won the $3 million Special Breakthrough Prize.
On the grandest scale, our universe is a network of galaxies tied together by the force of gravity. Cosmic Web, a new effort led by cosmologists and designers at Northeastern’s Center for Complex Network Research, offers a roadmap toward understanding how all of those tremendous clusters of stars connect—and the…
Ten years ago, billions of humans had their worldview upended when a group of astronomers announced that the solar system only contains eight planets. Now, the same guys are trying to rewrite our childhood mnemonics once again. A ninth planet may exist after all, and it isn’t Pluto.
Back in 2014, physicists on a collaboration known as BICEP2 thought they had detected gravitational waves. Those claims quickly evaporated when it became clear that they had really seen patterns from cosmic dust. But they haven’t given up the hunt. An upgraded version of the experiment, BICEP3, began taking new data…
The most powerful supercomputer simulation of the Universe is providing important insights into how matter is distributed across large scales. Surprisingly, a significant portion of matter resides outside of galaxies and in the cosmic voids that permeate the cosmos.
For years, astronomers have puzzled over “fast radio bursts” (FRBs), mysterious cosmic beats that may come from pulsars. Now, for the first time, researchers have pinpointed the location of one such burst—and the discovery hints at an even more epic origin story.
Inspired by the confirmation of gravitational waves, British composer Arthur Jeffes has taken data from the LIGO experiment and set it to music. Without a doubt, these billion-year-old ripples coursing through the fabric of spacetime never sounded so good.
The rumors were true! This morning leaders of the Laser Interferometer Gravitational Wave Observatory (LIGO) announced the first direct detection of gravitational waves. In honor of this momentous discovery, the Perimeter Institute in Waterloo, Ontario, is hosting a live webcast today at 1pm EST: “Ripple Effects: A…
Now you can watch as well as listen as world-renowned physicist Stephen Hawking expounds upon his latest ideas about the knotty black hole information paradox, playfully illustrated by chalkboard artist Andrew Park.
The Milky Way may have 13.6 billion years under its belt, but its stars range from newborns to ancients. Astronomers mapped how old the stars are, creating the first-ever age map of our galaxy—and this map could give us clues about how life in the Milky Way started.
In the starless void of intergalactic space, there are clouds of cosmic gas as old as the Milky Way. They produce no visible light, and they barely radiate heat. Now, for the first time, astronomers have determined their size. These shadowy structures are as big as galaxies.
A controversial experiment at Fermilab designed to hunt for signs that our universe may really be a hologram has failed to find the evidence it was seeking, the laboratory has announced.
Billions of years from now, the universe as we know it will cease to exist. The good news is, that gives us a lot of time to prepare, and maybe even figure out a way to cheat cosmic death. Here are some possible ways our descendants might survive a cosmological apocalypse.
The nuclear strong force binds the smallest bits of matter together to form atoms, thereby making our material world possible. Physicists at Brookhaven National Laboratory have made the first-ever measurement of a similar strong force for antimatter — the mirror image of regular matter that lies at the heart of one of…
Perhaps you saw the news this week about new evidence that we do, indeed, live in a multiverse. A scientist claims he’s found signs in the cosmic microwave background radiation — the afterglow, so to speak, from the Big Bang — that our universe collided with another universe early in our cosmic history.
You’ve heard it before: In space, no one can hear you scream. That’s because sound doesn’t move through a vacuum, and everyone knows that space is a vacuum. The thing is, that’s not completely true.
All eyes are currently on the upgraded Large Hadron Collider as it ramps up its hunt for new physics. But some physicists are already looking beyond and pinning their hopes on an even bigger machine, four times the size of the LHC. One of them is Nima Arkani-Hamed, the subject of a recent extensive profile by Natalie…
