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.
