Cafe Scientifique at Hope Street Hotel
Café Scientifique is a forum for debating science issues and promoting public engagement with science. Audiences consist of people who are interested in science but generally never have the opportunity to discuss their views with, and ask questions of, someone “in the know”.
Meetings generally start with a short talk from the speaker, who is usually a scientist or a writer on science, followed by a short break for drinks. This is followed by a session of about an hour for questions and answers and general discussion. Cafés are free although a voluntary contribution may be asked for to cover any expenses. (It does not pay fees to a speaker).
Meetings take place once a month on the second Wednesday of each month, starting at 7.30pm.
Next Meeting: Wednesday, 8th July, 2015
Place: The Old Bookroom, Hope Street Hotel
Speaker: Professor Chris Collins, from the Astrophysics Research Institute of Liverpool John Moores University
The universe began over 13 billion years ago with the Big Bang and is expanding. Surprisingly, the expansion rate is accelerating. This has been explained by the idea of dark energy – energy that is otherwise not detected except for its gravitational effects. Claims of a large under density or void in the matter distribution on scales out to 300 million parsecs have recently been made using samples of galaxies. These results could have profound implications for the Big Bang providing an alternative explanation for the acceleration of the universe without the need for dark energy. In this talk Professor Chris Collins will discuss the results of an alternative test of the matter distribution on these large scales using clusters of galaxies, which provide an independent and powerful probe of large-scale structure. Professor Collins will also discuss the cosmological implications of these findings.
