Physicist Brian Cox explains how black holes could unlock the mysteries of our universe. The problem was black holes, quantum mechanics, general relativity – when you put them together you have this apparent prediction that these things erase information from the Universe. This became known as the 'Black hole information paradox.' It turns out if we fast forward to the present day and a series of papers are still being written, so this is still research that's happening as we speak, but it turns out now that the general view is that black holes do not erase information from the Universe. #universe #blackholes #briancox
