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.
For almost five millennia, the geocentric model of the Earth as the center of the universe had been accepted by all but a few astronomers.

Nothing would. As things stand now, the whole universe should have annihilated itself. But, obviously, the universe has not annihilated itself. After all, we’re here to ask all these probing ...
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.

c. 16th century BCE – Mesopotamian cosmology has a flat, circular Earth enclosed in a cosmic ocean.

Scientists have made a precise map of all the matter in the universe. The new map represents one of the most precise measurements of how all the stuff in the universe is distributed across the ...
The Big Crunch is a hypothetical scenario for the ultimate fate of the universe, in which the expansion of the universe eventually reverses and the universe recollapses, ultimately causing the cosmic scale factor to reach absolute zero, an event potentially followed by a reformation of the universe starting with another Big Bang.
Two teams of scientists have discovered a theoretically habitable planet called Gliese 12b that’s smaller than Earth but bigger than Venus, just 40 light-years away.
