Researchers Devise a New Way to Solve Long-Standing Mystery About the Universe Researchers Devise a New Way to Solve Long-Standing Mystery About the Universe

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.

Trump's Budget Would Scrap Top-Priority Telescope Trump's Budget Would Scrap Top-Priority Telescope

President Donald Trump’s 2019 budget request would nix the Wide Field Infrared Survey Telescope (WFIRST), and scientists aren’t happy.

Synchronized Galactic Orbit Challenges Our Best Theory of How the Universe Works Synchronized Galactic Orbit Challenges Our Best Theory of How the Universe Works

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…

What's the Speed of Dark Matter? What's the Speed of Dark Matter?

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.

Watch Live as Physicists Discuss the Mysteries of Dark Matter at Gizmodo Watch Live as Physicists Discuss the Mysteries of Dark Matter at Gizmodo

We live in a universe filled with weird stuff that we don’t really understand: dark matter. Physicists have observed its spooky effects but have’t seen it directly. Even scarier: There seems to be around six times as much dark matter in the universe as regular matter.

New 3D Map of the Universe Features a Whopping 1.2 Million Galaxies New 3D Map of the Universe Features a Whopping 1.2 Million Galaxies

The astronomical map you see here doesn’t depict stars, it shows galaxies—1.2 million of them, to be exact, a new record for astronomers. This extraordinary new 3D scan of the universe provides yet more evidence that a mysterious substance known as dark energy is likely causing the universe to expand at an…

What exactly is dark matter?

We don’t know what dark matter is but we do know it exists. We know what it’s not though and Kurz Gesagt does its thing with another animated video explainer trying to break down what dark matter and dark energy is. Which is basically, we know something is out there, it interacts with gravity and there is a lot of it.

How Can Space Travel Faster Than The Speed Of Light? How Can Space Travel Faster Than The Speed Of Light?

Light speed is often spoken of as a cosmic speed limit … but not everything plays by these rules. In fact, space itself can expand faster than a photon could ever hope to travel.

​Without Dark Matter, There Would Be No Life ​Without Dark Matter, There Would Be No Life

The evolution of life is a 13.8 billion-year-long chain of events, from the Big Bang through the creation of chemical elements, galaxies, planets and the first self-replicating organisms. But without dark matter's influence, says an astrophysicist, it's hard to see how anything as complex as life could have emerged.

How big is the Universe, explained in a way you will easily understand How big is the Universe, explained in a way you will easily understand

The Royal Observatory of Greenwich, England, has crafted three simple animations to explain three very complex things: What's inside a black hole, how do we know the age of the sun—did you know the Sun weighs 4,000 trillion trillion hippopotamuses?—and how big is the Universe.

Revised Cosmological Constant Predicts a Collapsing Universe Revised Cosmological Constant Predicts a Collapsing Universe

The going theory among cosmologists is that the universe will eventually rip itself to shreds owing to its ever-accelerating rate of expansion. Not so, say a pair of physicists who have just taken it upon themselves to reformulate an integral facet of general relativity: the cosmological constant.

Here are the three ways that the universe will be destroyed

Nothing lives forever, not even our universe. Eventually it'll go kaput and be destroyed... but how? Smart people have wrapped their heads around the universe's destruction and have come upwith three different theories. The Big Rip, Heat Death (or the Big Freeze) and the Big Crunch and Big Bounce. They all sound like…

We might be destroying the universe just by looking at it We might be destroying the universe just by looking at it

It's not often that astronomy goes well with the book of Genesis. But this is a theory that evokes the line, "But of the tree of the knowledge, thou shalt not eat of it: for in the day that thou eatest thereof thou shalt surely die." In this theory, knowledge doesn't just kill you — it kills the entire universe.…

The Objects in Space That We Really, Really Can't Explain The Objects in Space That We Really, Really Can't Explain

Forget UFOs — there are a lot of objects and events in space that are identified, but still completely incomprehensible. From planets in our solar system, to inexplicable energy bursts from across the universe, here are some of the enduring mysteries of the space and time we call home.

Universe's most mysterious force holds answer to our ultimate destiny Universe's most mysterious force holds answer to our ultimate destiny

Dark Energy. We think it exists. We think it accounts for about 70 percent of our reality. This mystery force can give us the solution to the Universe's final destiny, but we are just beginning to understand it, according to Mordecai-Mark Mac Low at the American Museum of Natural History.

A Brief History of Dark Energy A Brief History of Dark Energy

In the last century, we've learned that the universe is expanding. Dark energy, which accounts for about 70 percent of the stuff in the universe, is the mysterious phenomenon accelerating this expansion.

This New Space Show will Bend Your Mind This New Space Show will Bend Your Mind

Observe the night sky at the historic Mount Wilson Observatory, soar across the Milky Way Galaxy, and parachute through Jupiter’s atmosphere in Dark Universe, the new Hayden Planetarium Space Show opening at the American Museum of Natural History on Saturday, November 2.

How red light revealed that the Universe is expanding How red light revealed that the Universe is expanding

We have known for some time that the universe is expanding, and that its expansion is accelerating. But how do we know that? We'll show you how Edwin Hubble revealed that the universe is getting away from us.

Is there a link between the Higgs boson and dark energy? Is there a link between the Higgs boson and dark energy?

The Universe is expanding at an accelerating rate and we’re not entirely sure why. To deal with the problem, scientists have conjured up dark energy, a mysterious force that permeates all of space. Now, a pair of physicists say the newly discovered Higgs boson could help explain where it all comes from.

Einstein may have discovered dark energy without even realizing it Einstein may have discovered dark energy without even realizing it

An historian of science from New York University has re-interpreted a correspondence between Albert Einstein and Erwin Schrodinger in which the two scientists argued about the nature of the cosmological constant — a kluge that Einstein embedded in his general theory of relativity to explain why the Universe was…
