The Era of Gravitational Waves has Begun

We stand at beginning of a new era. Gravitational waves have been detected by LIGO coming from a pair of black holes colliding (wow, it feels good to type that). Gravitational wave astronomy is firmly a reality — in the official, peer-reviewed sense of the word.

I’m incredibly lucky to have found myself in the midst of it all, a tiny part of the team that made the first direct gravitational wave detection. But what does it all mean? Continue reading

It’s now almost a century since Albert Einstein published his general theory of relativity and we’re still trying to find a flaw in it. It remains our best theory of space, time and gravity. But, as ever in science, we’re constantly striving to test it in new ways in the hope that some experiment or observation will disagree with the theoretical prediction. We hope this because it’s certain that general relativity isn’t the full picture.

Recent discoveries just might help reveal what we’re missing.
