As part of Imperial College Astrophysics’ ongoing series “The Big Questions”, I’ll be in discussion with Subir Sarkar of Oxford here at Imperial on Tuesday, 21 July 2009. We’ll be debating the fate of the Universe, and, more specifically, the existence or otherwise of Dark Energy, which appears to be causing the Universe to accelerate in its expansion.

I expect this will be less metaphysical — but perhaps no less contentious! — than the previous debate, between Professor Michael Rowan-Robinson from Imperial and the Rev. Dr John Polkinghorne KBE FRS on “The Origin of the Universe”.

Tickets are free, but please register in advance.
