Scientists have made a huge discovery about the universe - they have detected the waves made after two black holes collided.
Black holes can't be seen, but scientists know they exist because of the way they move things around them in the universe.
In a far away galaxy, two black holes smashed together more than a billion years ago.
The shock waves from this crash have just reached earth, and scientists were able to detect the signal for the first time.
Prof. Stephen Hawking says discovery of gravitational waves provides ‘completely new way
They have observed the warping of space-time generated by the collision of two black holes more than a billion light-years from Earth.
The international team says the first detection of these gravitational waves will usher in a new era for astronomy.
It is the culmination of decades of searching and could ultimately offer a window on the Big Bang.
The research, by the Ligo Collaboration, has been published today in the journalPhysical Review Letters.
The collaboration operates a number of labs around the world that fire lasers through long tunnels, trying to sense ripples in the fabric of space-time.
