Over 100 years after Einstein proposed his theory of general relativity, we are proud to announce that his final major prediction has been verified! Gravitational waves have officially been detected by LIGO! This is a huge deal and an exciting new step in understanding our universe.

If vacuum energy really does have the enormous value predicted by quantum field theory then our gently expanding, geometrically flat universe shouldn’t exist. This is the vacuum catastrophe.

We’ll soon be capable of building self-replicating robots. This will not only change humanity’s future but reshape the galaxy as we know it.

With the large hadron collider running out of places to look for clues to a deeper theory of physics, we need a bigger particle accelerator. We have one - the galaxy.

Billions of galaxies, each with billions of stars, each with … rather a lot of particles in them. And then there's dark matter, black holes, planets, and the particles and radiation in between the stars and galaxies. But… is the universe actually made of stuff? An increasing number of physicists view the universe – view reality as informational at its most fundamental level.
