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.

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 ...

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 ...

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 ...
