SPACE: New Map Reveals Filaments of Dark Matter That Connect Galaxies

by
Dark Matter

A new map of dark matter made using artificial intelligence reveals hidden filaments of the invisible stuff bridging galaxies. The map focuses on the local universe — the neighborhood surrounding the Milky Way. Despite being close by, the local universe is difficult to map because it’s chock full of complex structures made of visible matter, said Donghui Jeong, an astrophysicist at Pennsylvania State University and the lead author of the new research. “We have to reverse engineer to know where dark matter is by looking at galaxies,” Jeong told Live Science.

SPACE: What If Black Holes Aren’t Black – Or Holes?

Black holes, those gravitational monsters so named because no light can escape their clutches, are by far the most mysterious objects in the universe. But a new theory proposes that black holes may not be black at all. According to a new study, these black holes may instead be dark stars home to exotic physics at their core. This mysterious new physics may cause these dark stars to emit a strange type of radiation; that radiation could in turn explain all the mysterious dark matter in the universe, which tugs on everything but emits no light. Dark Stars Thanks to … Read more

SPACE: Is Dark Matter Really A Bunch of Tiny Black Holes?

The universe might be full of tiny, ancient black holes. And researchers might be able to prove it. These mini black holes from the beginning of time, or primordial black holes (PBHs), were first dreamed up decades ago. Researchers proposed them as an explanation for dark matter, an unseen substance that exerts a gravitational pull throughout space. Most explanations for dark matter involve hypothetical particles with special properties that help them evade detection. But some researchers think swarms of little black holes moving like clouds through space offer a cleaner explanation. Now, a new study explains where these PBHs might … Read more

Is There Dark Matter Inside the Earth?

by
super collider

Dark matter is a hypothetical component to our universe, used to explain many strange behaviors of stars and galaxies. Despite the almost overwhelming evidence that dark matter does indeed exist, we still don’t know what it’s made of. Detectors scattered around the world have been operating for decades, trying to catch the faint trace of a passing dark matter particle, but to no avail. A new paper offers an alternative approach: dig deep. We know that dark matter exists through a variety of astronomical observations. Stars are orbiting the centers of their galaxies too fast. Galaxies are whizzing around inside … Read more

Did German Physicists Accidentally Discover Dark Matter 6 Years Ago?

Could we have already discovered dark matter? That’s the question put forth in a new paper published Feb.12 in the Journal of Physics G. The authors outlined how dark matter might be made of a particle known as the d*(2380) hexaquark, which was likely detected in 2014. Dark matter, which exerts gravitational pull but emits no light, isn’t something anyone’s ever touched or seen. We don’t know what it’s made of, and countless searches for the stuff have come up empty. But an overwhelming majority of physicists are convinced it exists. The evidence is plastered all over the universe: Clusters … Read more

First There Was Dark Matter. Now We Have Dark Fluid – Live Science

d It’s embarrassing, but astrophysicists are the first to admit it. Our best theoretical model can only explain 5 percent of the universe. The remaining 95 percent is famously made up almost entirely of invisible, unknown material dubbed dark energy and dark matter. So even though there are a billion trillion stars in the observable universe, they are actually extremely rare. The two mysterious dark substances can only be inferred from gravitational effects. Dark matter may be an invisible material, but it exerts a gravitational force on surrounding matter that we can measure. Dark energy is a repulsive force that … Read more

SCIENCE: What Is Dark Matter?

by

In the 1930s, a Swiss astronomer named Fritz Zwicky noticed that galaxies in a distant cluster were orbiting one another much faster than they should have been given the amount of visible mass they had. He proposed than an unseen substance, which he called dark matter, might be tugging gravitationally on these galaxies. Since then, researchers have confirmed that this mysterious material can be found throughout the cosmos, and that it is six times more abundant than the normal matter that makes up ordinary things like stars and people. Yet despite seeing dark matter throughout the universe, scientists are mostly … Read more

SPACE: Dark Matter Hurricane’s a Comin’

dark matter hurricane

Scientists think there’s a “dark matter hurricane” heading toward Earth. In fact, it might even be blowing through us already. But don’t worry — it’s definitely not going to kill you. Mostly, it’s just a bunch of normal dark matter with especially good branding. And it really is headed (more or less) this way. Here’s what’s going on: Back in 2017, astronomers spotted a stretched-out line of stars passing through our solar system’s general region of the Milky Way. The scientists named this group the “S1 stream,” identifying it as the nearest of several stellar streams moving through the galaxy. … Read more

All of the ordinary matter in the universe, from stars to Cher herself, accounts for less than 5% of the known universe. About 25% of the universe is dark matter, while the remaining 70% is dark energy. But what are these dark, invisible substances? Well…we don’t know exactly, but we do have some ideas!
