Quantum steps towards the Big Bang
(Phys.org) —Present-day physics cannot describe what happened in the Big Bang. Quantum theory and the theory of relativity fail in this almost infinitely dense and hot primal state of the universe. Only ...
Did Andromeda crash into the Milky Way 10 billion years ago?
(Phys.org) —For many years scientists have believed that our Galaxy, the Milky Way, is set to crash into its larger neighbour, the Andromeda Galaxy, in about 3 billion years' time and that this will be ...
For the first time, astronomers have measured the radius of a black hole
(Phys.org)—The point of no return: In astronomy, it's known as a black hole—a region in space where the pull of gravity is so strong that nothing, not even light, can escape. Black holes that can be billions ...
