Ripples from the Big Bang

Ripples from the Big Bang

St Peter's School welcomes Professor Jo Dunkley on Wednesday 8 June as she delivers a lecture entitled 'Ripples from the Big Bang'. 

By looking far out into space, we can see back almost to the dawn of time.  Faint microwave light is reaching us now that set off on its journey almost 14 billion years ago. It carries a picture of what the Universe looked like back then, and helps us find out how galaxies like our own Milky Way came to be here billions of years later. It also helps us discover what was happening at the Big Bang itself.

In her lecture, Professor Dunkley will talk about the space satellites and telescopes at the South Pole and in Chile that we are using to study this light, and what we are learning from them about the beginning of the Universe.
