Two new theories propose dark matter either formed in a “mirror” universe or emerged from the cosmic horizon’s quantum ...

Two recent studies by Professor Stefano Profumo at the University of California, Santa Cruz, propose theories that attempt to ...

Bold new theories on "mirror worlds" and how dark matter may have formed - from black hole relics to quantum horizons.

First and perhaps most perplexingly, researchers remain unsure about what exactly dark matter is. Originally, some scientists ...

Dark matter is a hypothetical substance that outweighs regular matter (which makes up us and everything we can see in the universe) five to one. We do not know what it is and have not confirmed its ...

Neutrinos are fundamental particles characterized by no electric charge and very small masses, which are known to interact ...

Dark matter in an asteroid interacting with real matter in a star basically amounts to unity (because stars are rather dense). Based on what we know about the Universe and how galaxies form, dark ...

Although it hasn’t detected dark matter yet, its developers say it offers an alternative path that is worth exploring ...

Two theoretical physicists at the University of California, Davis, have a new candidate for dark matter, and a possible way to detect it. They presented their work June 6 at the Planck 2019 conference ...

As two galaxies passed through one another, the regular matter from each galaxy interacted, causing a cosmic logjam in the center. Yet, the dark matter seems to have ghosted through the collision.

Two recent studies speculate a natural emergence of the mysterious substance, offering ‘self-contained and calculable ...
