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, ...

The dark matter responds to this by migrating out from the centre of the galaxy, an effect known as ‘dark matter heating’. J. I. Read, M. G. Walker, & P. Steger (2019), MNRAS 484, 1 ...

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

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

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

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.

Dark matter is a hypothetical substance that is invoked by physicists to explain the large-scale structure of the universe. While it has never been observed directly, it is a part of the current ...

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.
