Just milliseconds after the universe's Big Bang, chaos reigned. Atomic nuclei fused and broke apart in hot, frenzied motion. Incredibly strong pressure waves built up and squeezed matter so tightly together that black holes ...

While many studies have hinted at the existence of dark matter, a material that does not absorb, reflect or emit light, this elusive substance has not been directly observed so far. Over the past few decades, many teams worldwide ...
Primordial black holes created in the first instants after the Big Bang—tiny ones smaller than the head of a pin and supermassive ones covering billions of miles—may account for all of the dark matter in the universe.

In September 2020, the LIGO/Virgo collaboration, a large team of scientists working at different universities worldwide, announced that they had detected most massive gravitational wave binary signal observed to date, which ...
A recent study suggests the possible existence of 'stupendously large black holes' or SLABS, even larger than the supermassive black holes already observed in the centers of galaxies.

It is probable that primordial galaxies triggered the period in the history of the universe known as "cosmic reionization." The Geneva-based astronomer Anne Verhamme has succeeded in demonstrating this by studying green pea ...
