Are the laws of physics the same everywhere?

25 January 2012

Question

Firstly, I love the podcast. It's the right blend of basic facts blended with complex concepts which keep the amateur astronomer and scientist like me entertained, educated and never patronised. Thanks for all the ear candy for the last year and more I've been listening.

One of the basic assumptions of cosmology is the laws of physics as we know them hold true throughout the observable universe. What evidence is there for this?

Thanks again.
Brian
