In 5 Billion Years, The Expansion Of

Science Has Been Effective At Furthering Our Understanding Of Nature Because The Scientific Ethos Is Based On Three Key Principles: (1) Follow The Evidence Wherever It Leads; (2) If One Has A Theory, One Needs To Be Willing To Try To Prove It Wrong As Much As One Tries To Prove That It Is Right; (3) The Ultimate Arbiter Of Truth Is Experiment, Not The Comfort One Derives From One's A Priori Beliefs, Nor The Beauty Or Elegance One Ascribes To One's Theoretical Models.

The Real Thing That Physics Tell Us About The Universe Is That It's Big, Rare Event Happens All The Time — Including Life — And That Doesn't Mean It's Special.

The Illusion Of Purpose And Design Is Perhaps The Most Pervasive Illusion About Nature That Science Has To Confront On A Daily Basis.

Now, Since The Time Of Newton There Had Been A Debate About Whether Light Was A Wave - That Is, A Traveling Disturbance In Some Background Medium - Or A Particle, Which Travels Regardless Of The Presence Of A Background Medium. The Observation Of Maxwell That Electromagnetic Waves Must Exist And That Their Speed Was Identical To That Of Light Ended The Debate: Light Was An Electromagnetic Wave.

Occam's Razor Suggests That, If Some Event Is Physically Plausible, We Don't Need Recourse To More Extraordinary Claims For Its Being. Surely The Requirement Of An All-powerful Deity Who Somehow Exists Outside Of Our Universe, Or Multiverse, While At The Same Time Governing What Goes On Inside It, Is One Such Claim. It Should Thus Be A Claim Of Last, Rather Than First, Resort.
