Early universe observations by the James Webb Space Telescope cannot be explained by current cosmological models.

A map of the universe in gravitational waves could reveal "hidden" black holes, supermassive black hole collisions, and the large-scale structure of the cosmos.

One of these interpretations, known as the pilot-wave theory, posits that every interaction in the universe can be described by a single set of equations — if only we could figure those out.

The prevailing theory is that the modern universe formed after a cosmological Big Bang, followed by a period of rapid inflation. The expansion of the universe, the cosmic microwave background (CMB ...

Some are arguing that Many Worlds and Pilot Wave are really the same. It’s hard to interpret the strange results of quantum mechanics, though many have tried. Interpretations range from the ...

According to Albert Einstein’s general theory of relativity, the universe remembers every gravitational wave—and scientists could soon test these cosmic recollections ...

A new hypothesis suggests that the universe may be twice as old as we had believed. Observations from the James Webb Space Telescope provide new information on the rate of the universe’s expansion.

In some interpretations of quantum mechanics, such as the Many-Worlds interpretation or the Pilot Wave Theory, parallel universes may form every time a subatomic particle goes through any interaction.

LIGO detects gravitational waves, which allow astrophysicists to peek directly into the heart of some of these most spectacular phenomena in the universe.

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.
