Might the universe we can observe be just half the tale, with a mirror universe moving in reverse through time filling out ...

What do quarks, electrons, and photons have in common? They’re all part of the Standard Model - the theory that helped ...

Another challenge to the Standard Model, this one cosmic, is dark matter and dark energy. These hypotheses are at the base of another standard model, the Standard Model of Cosmology.

Astrophysicists need precise tests of the model because its ingredients are not completely certain. Dark matter has never been directly detected.

The aforementioned models of the cosmos, including the standard model of cosmology, have long posited the idea that the missing baryonic matter of the universe is locked up in vast filaments of ...

The James Webb Space Telescope's discovery of unusually bright and massive galaxies soon after the Big Bang has cast doubt on the standard model of galaxy evolution and bolstered a rival theory ...

Two colliding galaxies have been found to be reorganizing their dwarf satellites, potentially solving a major conundrum ...

Some extensions of the Standard Model exhibit similar discrete symmetry breaking, wherein the scalar field representing the minimal energy state, or vacuum state, of spacetime itself takes on ...

Standard Model math also does not include the mysterious dark matter that lurks within and between galaxies, nor does it explain why empty space is infused with a form of energy that causes the ...

For years, scientists have used a well-established model to explain how the universe evolves. The standard theory, called the Lambda Cold Dark Matter model (ΛCDM), is the prevailing cosmological ...

Two studies fill in gaps about the cosmos’s ordinary matter. One maps it all, even the “missing matter.” The other details one of its hiding spots.
