Albert Einstein made an executive decision to revolutionise our understanding of gravity in a paper published in 1916. Nearly 100 years on, a key prediction of Einstein’s theory has eluded direct detection…
There's more to gravity than apples falling from trees.

I have spent almost 40 years trying to detect gravity waves.
When I started there were just a few of us working away in university labs. Today 1,000 physicists working with billion-dollar observatories…
If the signs are right, fundamental equations of cosmology may need altering.

A radical discovery by my colleagues and I – reported this week in Physical Review Letters – could help explain why it was possible for life (at least as we know it) to develop on Earth, but not in other…
The GPS on your phone couldn’t work without General Relativity.

It’s the year 2100. You wake up alone in a small, windowless room. The only other thing in the room is a small ball. Maybe the room is located in your city, but maybe it’s inside that new spaceship everyone…
We know they're out there, and now we're closer than ever to finding gravity waves.

Detecting gravity waves is a major goal for astrophysicists.
We know they should be there, but we haven’t found them yet. But today we are one step closer.
By literally squeezing light on a quantum level…
What tasty treats await astronomers in the next few decades?

Predicting the future is a mug’s game.
When I reflect back on what we thought we knew at the start of my research career in the mid-1990s, I sound like a wizened octogenarian, recalling a simpler time…
The universe teems with energy and matter we don't understand.

In questioning the fundamental nature of the universe, cosmology regularly grabs the public’s attention.
But in an era in which we are observing deeper and more widely than ever before, our knowledge…
Quantum mechanics (the theory of atoms, quarks and photons) is definitely weird and, thanks to the work I’m doing, it might be getting weirder.
Allow me to throw a quantum spanner in the works.
In the…
