Could the Universe have been born inside a black hole? This question, raised by a team of scientists, challenges the Big Bang ...

The Big Bang may mark an end—not the start—of a previous universe's aeon. Penrose's theory sees the universe as an eternal ...

By putting prevailing modern cosmological theories, known as the Standard Model of Cosmology, on even firmer evidentiary and statistical footing, Pantheon+ further closes the door on alternative ...

A new cosmological simulator logs its scientific predictions and refutations in real time, storing hashes in blockchain with full offline ...

By putting prevailing modern cosmological theories, known as the Standard Model of Cosmology, on even firmer evidentiary and statistical footing, Pantheon+ further closes the door on alternative ...

The prevailing theory is that the modern universe formed after a cosmological Big Bang, followed by a period of rapid ...

What we saw in the DESI experiments, and now strengthened by our South Pole Telescope observations, is that dark energy is ...

The earliest and most distant supermassive black hole discovered thus far by JWST is CEERS 1019, which existed just 570 ...

The potential problem with distant galaxies isn't that they exist. In fact, the modern formulation of the Big Bang theory, called ΛCDM cosmology (the Λ stands for dark energy, and CDM is short ...

In 1929, Edwin Hubble calculated the velocity of distant galaxies barely visible through the telescopes at the Mount Wilson Observatory. His observations were the first evidence of a theory that has ...

A theory known as non-singular matter bouncing cosmology suggests that the universe “bounces” between a hot big bang era and the kind of universe we see today.
