Was there really a big bang?

keating_brianCosmologist Brian Keating:

‘You can’t prove a theory, but you can falsify alternatives to it. What’s raging right now in cosmology is the question of whether inflation is a theory. Is it science? Is it falsifiable? There are many eminent cosmologists and theoreticians, from Roger Penrose, Paul Steinhardt, and many others who are just as eminent as a physicist working on inflationary cosmology, who claim that not only is it not provable, it’s not even science because it cannot in principal be falsified.’
