If the current laws of physics prove to be inaccurate we can always change them to fit reality. It's the great thing about science. You can swear it's the truth one day and calmly say you were wrong the next day. No harm no foul.
Science is not interested in "truth". That is the terrain of the religious. Science is interested in facts. We observe the physical world and record what we see. If a scientist begins talking about morality he is no longer a scientist, he has become a high priest advocating for whatever religion he happens to be pushing..
It's interesting to hear you say that science is not interested in truth. Are scientists interested in lies then? I would say that science is only interested in truth. Truths that can be observed, truths that can be documented, truths that can be measured, truths that can be tested. Truth doesn't really have anything to do with morality except to say that it is immoral to lie.
There isn't really anything wrong with scientists talking about morality either. As long as they understand where the science ends and the morality begins.
NO! Science is interested in facts and facts alone! There are no "truths" in science. Everytime we build a better instrument we find out that facts we knew to be accurate no longer are.
All through the history of science there has been a continuous increase not only in our knowledge but in our ability to measure, to observe at the smallest level, to modify the very elements of matter.
Every time that occurs some new "truth" would be discovered and an old "truth" would be cast aside. That's why science doesn't bother itself with truth. Science is solely about observing the physical world and understanding how we can use what has been discovered.
And you're wrong about scientists speaking about moral values. I have no problem with a scientist talking about morality so long as he does it as a private person and doesn't use his credentials as some sort of credibility booster.
If they use their position as scientists to speak on morality issues then they have crossed an ethical and professional line. They LOSE credibility in the scientific world whenever they do that.
