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.

In 5 Billion Years, The Expansion Of The Universe Will Have Progressed To The Point Where All Other Galaxies Will Have Receded Beyond Detection. Indeed, They Will Be Receding Faster Than The Speed Of Light, So Detection Will Be Impossible. Future Civilizations Will Discover Science And All Its Laws, And Never Know About Other Galaxies Or The Cosmic Background Radiation. They Will Inevitably Come To The Wrong Conclusion About The Universe......we Live In A Special Time, The Only Time, Where We Can Observationally Verify That We Live In A Special Time.

We All Trust Each Other To Some Extent. We Have To Rely On Experts To Some Extent, But We Should Learn To Be Sceptical.
