Dark Matter Detector Discovers the Rarest Occasion Ever Seen in deep space

Dark Matter Detector Discovers the Rarest Occasion Ever Seen in deep...

Since the 1960s, scientists have theorized that the Universe is filled with a mysterious, invisible mass. Known as “dark matter“, this mass is estimated to make up roughly 85% of the matter in the Universe and a quarter of its energy density. While this mass has been indirectly observed and studied, all attempts at determining…

For over fifty years, scientists have theorized that roughly 85% of matter in the Universe’s is made up of a mysterious, invisible mass. Since then, multiple observation campaigns have indirectly witnessed the effects that this “Dark Matter” has on the Universe. Unfortunately, all attempts to detect it so far have failed, leading scientists to propose…

Enlarge / 19th-century etching of a telescope in use. Much of the Universe behaves as if there's more matter there than we can see. Dark matter explains this by positing that there's matter present that we can't see, and evidence has piled up in favor of this idea. In contrast, evidence for the identify of…

I’ll be the first to admit that we don’t understand dark matter. We do know for sure that something funny is going on at large scales in the universe (“large” here meaning at least as big as galaxies). In short, the numbers just aren’t adding up. For example, when we look at a galaxy and…

WFIRST ain’t your grandma’s space telescope. Despite having the same size mirror as the surprisingly reliable Hubble Space Telescope, clocking in at 2.4 meters across, this puppy will pack a punch with a gigantic 300 megapixel camera, enabling it to snap a single image with an area a hundred times greater than the Hubble. With…

Enlarge / Neutron stars may produce radio signals when interacting with dark matter. Dark matter is proving elusive. Apart from the gravitational evidence, which is strong, all the other potential indications of it haven't held up to scrutiny. One issue may be that we simply don’t know how to look for it, so detectors are…
Gravitational Waves May be the Secret to Finding Dark Matter

Gravitational Waves May be the Secret to Finding Dark Matter

Exotic dark matter theories. Gravitational waves. Observatories in space. Giant black holes. Colliding galaxies. Lasers. If you’re a fan of all the awesomest stuff in the universe, then this article is for you. Most of the contents of our universe are of a form completely unknown to physics. That’s just a raw fact that we’re…

In February of 2016, scientists working for the Laser Interferometer Gravitational-Wave Observatory (LIGO) made history when they announced the first-ever detection of gravitational waves. Since that time, multiple detections have taken place and scientific collaborations between observatories  – like Advanced LIGO and Advanced Virgo – are allowing for unprecedented levels of sensitivity and data sharing.…

Enlarge / IceCube is actually under the ice, pointing downward. The Earth is a big filter to remove all the other stuff the universe throws at us. I’ve largely given up writing stories about new dark-matter candidates. Theoretical physicists keep coming up with more elaborate scenarios to make dark matter more interesting and less inert.…
