I attended a conference on thallium based superconductors at Breckenridge Colorado in 1995. I happened to ask a young Russian scientist what year this was in Russia. Surprised, he said it was 1995, of course. Then he noted that it was 1995 throughout the entire world. But, you can't get truth from science.
Science is based on observation and experimentation.
But, scientists are always discovering something new they didn't know before, which forces them to overhaul their theories. Scientists never know how much they don't know yet . They never have all the facts. You can only get the truth if you possess all the facts. It is illogical to think you can get truth from science .
