(Phys.org)—Physicists have proposed that violations of energy conservation in the early universe, as predicted by certain modified theories of quantum mechanics and quantum gravity, may explain the cosmological constant ...
No matter which direction you look in the universe, the view is basically the same if you look far enough. Our local neighborhood is populated with bright nebulae, star clusters and dark clouds of gas and dust. There are ...
