The next Long Eaton Astronomical Society meeting will be on Thursday March 27th at the slightly later time of 6:30pm. We will be joined by Simon Dye, a lecturer and researcher at Nottingham University who will be talking about dark matter.
Simon describes his talk as follows:
This talk will address one of the deepest mysteries of our Universe: Dark Matter. After a brief historical introduction to the notion of dark matter, I will discuss why we think this stuff is present in huge amounts in the Universe and what properties it has to have to agree with observations. I will explain how we can weigh dark matter and how we can measure the way in which it is spread within and around galaxies and clusters of galaxies. I will conclude with a discussion of alternatives to the idea of dark matter, focussing on whether we simply don’t understand gravity.
Refreshments will be from 6:15pm, as always – all are welcome. Children under 16 must be accompanied by an adult. Membership renewals will continue, membership is £8 for the rest of 2014 and forms will be available at the meeting. For non members we request a donation of £2 towards refreshments.
