At 7:00pm on Thursday 22 October, Dr Chris Clarkson will deliver the next in our series of public talks.
2 November 2018
Why is the universe the way that it is? Why is it expanding? Why is that expansion growing ever faster? On the boundless scales of the cosmos the most formidable of nature's forces is gravity. Einstein’s prediction that there isn't really a force of gravity at all but rather spacetime is curved, lies at the heart of our understanding of modern cosmology. His same theory predicts black holes and gravitational waves, now discovered in spectacular fashion. Examining the history of our expanding universe we are led by the same theory inevitably to some kind of big bang — but does the same theory predict dark energy driving an ever-accelerating universe, gradually diluting into nothing at all? Perhaps. In this talk Dr Chris Clarkson will descriibe our current understanding of the Universe at large and how future cosmological surveys will map the vast cosmic web of galaxies on scales so far only envisaged in prodigious computer simulations. Unravelling this delicate web will reveal not only the nature of the big bang itself, but the essence of dark energy — and with it, the future of the universe.
All are welcome to attend this talk, which will not be technical and is aimed at anyone who is interested. Please register your attendance here.
