Dark matter is known to make up roughly 85% of all mass in the universe, as evidenced by the way galaxies spin and how galaxy clusters are held together under gravity. Yet despite decades of searching, physicists have never ...
The universe is known to be expanding at an accelerating rate. Physicists typically attribute this acceleration to dark energy, a mysterious component of the universe that exerts negative pressure, causing space to expand ...
