How did we first work out that the universe was expanding?

• Galaxies were seen to be moving further and further apart

• Galaxies were seen to be spinning in an unexpected way

• Particle physics experiments showed that atoms were getting larger as the universe got older

How do particle accelerators allow us to effectively look back in time?

• If a scientist accelerates particles to a great enough speed, they travel backwards in time

• The high energy collisions of particles recreate the hot, dense conditions scientists think existed at the beginning of the universe

• Particle accelerators make wormholes that scientists can travel through to make measurements of the early universe
