This particular isotope burns away quickly inside stars due to their intense heat. But in cooler objects like brown dwarfs, ...

In a chilled lab where temperatures drop close to absolute zero, a speck of magnet hovers in place. This tiny magnet, ...

Celestial objects known as dark dwarfs may be hiding at the center of our galaxy and could offer key clues to uncover the ...

But axions were pushed aside as the WIMPs hypothesis gained more steam. Back-of-the-envelope calculations showed that the ...

CDM is still the standard model for dark matter because it works for building and maintaining cosmic structures such as galaxies. If dark matter is cold, then it can clump up and aggregate more ...

Researchers, in a recent Physical Review Letters paper, introduce a new mechanism that may finally allow ultralight dark ...

So, no matter what, you populate a universe with a collection of stars, just like in normal cold dark matter scenarios. But the researchers found a key observable difference.

While cold dark matter models like WIMPs predict the large scale structure and the number of big galaxies in the universe very well, historically they’ve struggled to reproduce the finer details ...

Matter in intergalactic space is not randomly scattered - it forms a vast network of filamentary structures that make up the ...

Do We Need a New Dark Matter Model? Season 9 Episode 21 | 16m 21s. Did we just uncover new evidence to support Cold Dark Matter? We have no idea what dark matter is, other than it’s some source ...

Our best theoretical model for the universe, the Lambda/Cold Dark Matter model (“ΛCDM”), predicts a value for H 0 of 67–68 km/s/Mpc. Our observations, however, put H 0 at around 73 km/s/Mpc.
