Timeline: the history of gravity

It's taken centuries for our understanding of gravity to evolve to where it is today, culminating in the discovery of gravitational waves, as predicted by Albert Einstein a century ago.

Gravitational waves discovered: the universe has spoken

The detection of gravitational waves is the final confirmation of Einstein's theory of general relativity, and opens up a new window into the cosmos.

Where are the missing gravitational waves?

A new study has failed to find evidence of gravitational waves, but that doesn't mean Einstein was wrong about their existence.

Gravitational wave discovery still clouded by galactic dust

One of this century’s greatest potential discoveries concerning the origins of the universe has now fallen to galactic dust. That’s according to a new joint-analysis of all the existing data – including…

BICEP2 ‘gravity wave’ finding clouded by interstellar dust

In March, scientists working on the BICEP2 experiment, a microwave telescope based at the South Pole, announced that they had seen ‘gravity waves’ from the early universe, created just after the Big Bang…
