Cape Centre News Letter, 05th May 2017

Dear Cape Centre members and friends,

Upcoming Events:

Cape Centre

10 May, 20:00, SAAO Auditorium:  Professor Bruce Bassett will give a talk titled Gravitational Waves – Einstein’s Final Exam and a Revolution for Astronomy. Bruce studied applied mathematics at UCT and completed a PhD at SISSA in Trieste and a post-doc at Oxford. His doctoral supervisor was the physicist Dennis Sciama, a father of modern cosmology who has been PhD advisor to many eminent scientists, including Stephen Hawking and our own George Ellis. Bruce is currently a Professor in the UCT department of mathematics, an astronomer at SAAO and a senior researcher in cosmology at the African Institute for Mathematical Sciences (AIMS). Gravitational waves are ripples in the fabric of space and time itself caused by colliding black holes and were first detected a little over a year ago by LIGO, opening up a new window on the Universe. In this talk, he will explore what they are, why Einstein predicted them a century ago, how they are created and why it has been so hard to find them. He will then discuss how they will revolutionise astronomy and end with the prospects of using gravitational waves to probe the very origin of the Universe.

17 (NOT 24) May, 20:00, SAAO Auditorium: Kate Storey-Fisher will speak on dark matter and dark energy.

V & A Waterfront Outreach

The next events are on 6 May and 3 June and all members and friends are invited to participate. It is not necessary to own a telescope, to be an astronomy expert or to attend every month. Contact Eddy Nijeboer on 082-335-4851eddy47@xsinet.co.za or the Cape Centre by replying to this email if you would like to share the pleasure of seeing what a telescope reveals of our solar system.
