How does gravity work? - Plus Maths
... One exciting possibility is the detection of waves that emanate all the way from the Big Bang. "A tiny fraction of a second after the Big Bang gravitational waves might have been produced. These are travelling to us unscathed without any corruption. By detecting them, we'll be able to deduce the con ...

However, the mechanisms that lead to their formation are still very much unknown. Astronomers also now believe that stars were the first large objects to ...
