The universe went in “extreme slow motion” at its beginning, and has dramatically sped up since, scientists have found. The discovery, predicted by Einstein’s general theory of relativity ...
Scientists know that it has been vital to the universe since its beginning, and new discoveries reveal that it could create black holes, cause mass extinctions, and might even have helped to shape life on Earth. Explores if there may be a dark matter universe that could account for all the events that aren't yet definable.
Although the distance traveled by light from the edge of the observable universe is close to the age of the universe times the speed of light, 13.8 billion light-years (4.2 × 10 ^ 9 pc), the proper distance is larger because the edge of the observable universe and the Earth have since moved further apart.

The result is unknown; a simple estimation would have all the matter and spacetime in the universe collapse into a dimensionless singularity back into how the universe started with the Big Bang, but at these scales unknown quantum effects need to be considered (see Quantum gravity). Recent evidence suggests that this scenario is unlikely but ...
Scientists on Wednesday unveiled evidence that gravitational waves, the ripples in the fabric of space-time predicted by Albert Einstein more than a century ago, are permeating the universe at low ...
The Big Bang is a physical theory that describes how the universe expanded from an initial state of high density and temperature. [1] The notion of an expanding universe was first scientifically originated by physicist Alexander Friedmann in 1922 with the mathematical derivation of the Friedmann equations.
At a conference in June, physicist Joao A. B. Coelho of the French Astroparticle and Cosmology Laboratory presented a project that shares a fair amount of DNA wit Twister’s Dorothy: a big group ...
1964 - First black hole, Cygnus X-1, discovered; 1964 – CP violation discovered by James Cronin and Val Fitch. 1965 – Arno Penzias and Robert Wilson: Cosmic Microwave Background (CMB) discovered; 1967 – Unification of weak interaction and electromagnetism (electroweak theory) 1967 – Solar neutrino problem found
