Dark matter formed when fast particles slowed down and got heavy, new theory says

Dark Matter Could Be Evolving, And The Implications Are Profound

For a while now, there has been a problematic mystery at the heart of the standard cosmological model.

Where did dark matter come from?

Researchers have an explanation for how dark matter emerged - beginning with weightless particles and ending with massive Cooper pairs.

Dark matter formed when fast particles slowed down and got heavy, new theory says

A study by Dartmouth researchers proposes a new theory about the origin of dark matter, the mysterious and invisible substance thought to give the universe its shape and structure. They say the hypothetical force shaping the universe sprang from particles that rapidly condensed, like steam into water.

Can gravity really work differently than thought? In this article Marcel Pawlowski talks about MOND, the alternative to dark matter.

New Evidence Reveals Dark Matter Might Be Evolving — And The Impact Is Far-Reaching

A groundbreaking new study, recently published on arXiv, challenges one of the most fundamental assumptions in cosmology: that dark matter remains constant over time. For decades, scientists have accepted that dark matter is a stable, non-evolving component of the Universe, responsible for shaping galaxies and driving cosmic structure. However, new research suggests dark matter might be evolving in an oscillatory manner, potentially solving long…

Chinese astronomers have identified a high-speed cloud – a vast halo of matter orbiting around the Milky Way – that could house a dark galaxy, this hypothetical type of galaxy composed exclusively of black matter. Its density and rotational dynamics correspond to those observed in some dwarf galaxies. This discovery could, to date, be the most tangible proof of the existence of these elusive cosmic objects. First discovered in 1963, [...] This a…
