Sue, the beauty of science is that it then goes on to demolish what it conditionally established as true. Proposition, experiment, result, new proposition, endlessly.

Scientist being human make mistakes. Science being a darn good way to think about and find truth is a self-correcting system by and large.

I hope and believe that if the species survives the science of the future will disprove most all falsehoods and establish most all truths. And I further hope and believe that folks in the future will look back at us and wonder how we could have been so crude, barbaric, ignorant, etcetera.
