This insightful event features talks by three scientists about three different astronomical topics with one theme tying them together - the fact that they are all studying what is effectively invisible.

After giving a short primer talk on each of their topics (including the hunt for dark matter, the detection of gravitational waves and using light our eyes can't detect to study galaxies), the panel will assemble to discuss how you can make the invisible, visible and what the challenges and rewards are in doing this. All in all there is definitely more to this event than meets the eye!

Age 14+

Speakers: Dr. Tessa Baker (University of Oxford), Joanna Ramasawmy (University of Hertfordshire), Prof. Jocelyn Monroe (Royal Holloway)

Dr Tessa Baker (@Tessa_M_Baker) is a cosmologist at the University of Oxford. She asks questions about how gravity affects the universe on the largest scales: why is it expanding so fast? Could Einstein have made a mistake when he figured out how gravity works? She uses giant telescopes and ripples in spacetime — known as gravitational waves — to try to answer some of these questions. When not trying to wrap her head around the universe, she is an avid pug-admirer, weight-lifter and chocolate connoisseur.
 
Gravitational Waves: the Sound of Spacetime
 
Nearly everything we’ve learnt about the night sky so far has been brought to us by light from stars or distant galaxies. This light is collected by telescopes in much the same way we see things with our eyes. In February 2016, for the first time, a completely new way to study the universe was opened up. Gravitational waves are ripples in the fabric of spacetime itself, produced when black holes or exotic stars collide; they are effectively the `sound' of spacetime shaking. In this talk I’ll explain the incredible way we can now hear the universe, as well as see it.

This event kicks off our 'Universe Unseen' series of programmes running from April to September 2018.
