Exploding stars and new-born black holes — when the universe is your lab

Generally speaking, blowing up a star in the lab is frowned upon because a) it would destroy the Earth and b) the star won’t fit in the lab in the first place. As an astrophysicist, however, our labs are the universe and no-one seems to object when it is the one blowing things up. An astrophysicist’s job is to study those explosions using advanced satellites to learn about the fundamental workings of the universe. In this talk, you’ll be introduced to the most powerful explosions we know of — gamma-ray bursts — and understand why you wouldn’t exist without them. Along the way we’ll take in X-rays (and why Superman is a liar), new-born black holes, gravitational waves and how we can learn so much about the universe from what is basically just a dot on the sky.
