It's been 100 years coming, and the science world is abuzz with excitement. Scientists have discovered gravitational waves.

They shot a laser beam down a pair of tunnels, each 4 km long. Finding the beam wobbling by less than the width of an atom means that Einstein was right. He predicted gravitational waves, and this tiny wobble is the first time we've found evidence for them.

Now we know they exist, physicists can use gravitational waves to learn more about black holes and the beginning of the universe.

Visit Cosmos & Culture on the first floor of the Museum to see a prototype part of the detectors the scientists used.
