The dark side of the universe
Δημοσιεύτηκε στις 24 Απρ 2014
Public lecture by Dr Clare Burrage as part of the 2014 Edinburgh International Science Festival.
Billions
of years ago the Big Bang sent everything flying apart. In theory,
gravity should stop galaxies from moving apart and matter should
eventually re-collapse on itself. Surprisingly, we have learnt that
galaxies are actually moving apart with ever-increasing speed. Nothing
in our current knowledge of physics can explain this, but theorists are
developing a solution: dark energy. Roughly 70% of our universe is
comprised of dark energy and yet so little is known about it, but
satellite and laboratory experiments are under way. Join Dr Clare
Burrage as she reveals the nature of dark energy, how it affects other
matter in the universe, and what plans we have for observing this
mysterious force.
5:30 pm — 7:00 pm on Friday 18 April 2014 at National Museum of Scotland, Edinburgh.
