Physics Scientists recently observed two black holes that united into one, and in the process got a “kick” that flung the newly formed black hole away at high speed. That black hole zoomed off at about 5 million kilometers per hour, give or take a few million. The speed of light is just 200 times as fast.

Physics A physicist has designed an experiment – which if proved correct – means he will have discovered that information is the fifth form of matter. His previous research suggests that information is the fundamental building block of the universe and has physical mass.

Physics Researchers have developed a jelly-like material that can withstand the equivalent of an elephant standing on it and completely recover to its original shape, even though it’s 80% water. The soft-yet-strong material looks and feels like a squishy jelly but acts like an ultra-hard, shatterproof glass

Physics Euler’s 243-Year-Old mathematical puzzle that is known to have no classical solution has been found to be soluble if the objects being arrayed in a square grid show quantum behavior. It involves finding a way to arrange objects in a grid so that their properties don’t repeat in any row or column.
