Report How certain is our scientific knowledge? Honestly? in Physics and Mathematics Posted January 9 On 11/10/2020 at 12:28 AM, Omnifarious said: First off let me say I mean no disrespect. And if I seem brutally honest it's because it's my nature and belief in being forthright. There are a lot of things said in science documentaries and scientifically mined people that upset me. And they always speak with absolute certainty. Like this thing is perfectly well known and proven beyond a shadow of a doubt, like gravity. I wanted to ask you weather or not they were really true but then I thought it would be easier to ask you about science and our certainty of it in general. I've heard that scientists are supposed to be open minded and never to be too certain of any thing. But in my experience, scientists are people who say "This is the way thing are and that's the end of it." That you could not be a scientist unless you took things as absolutes. It's particularly difficult for me to question these people because I can't help but assume they speak from a position of knowledge of which I am ignorant. When people talk like it's already proven, I can't help but assume it has been. When you're sitting in class or studying a book, you don't question what they're saying. If you did, how would you learn anything? For example this one says that we will NEVER be able to leave our local group of galaxies because the rest of the universe is accelerating away from us faster then the speed of light. This one and this one state that traveling faster then the speed of light is impossible. Not just that it's impossible with current technology but it's impossible no matter how advanced we get. I tried to tell myself that we are always discovering new things, things we could not imagine before. I looked in the comments to see if anyone had the same thought and some did. But then someone countered that bay saying if we did learn anything could go faster then light, it would undo the laws of physics going back to Newton, who's work has proven solid to this day. And something that's always bothered me, the theory that the entire universe will inevitably end. So many time I've heard about how and when it will end. Once I went on one of those question posting websites and I asked "Will the universe end?" Not how will, not when will, just will? Is this something the scientists of the world know and agree on. The very first post I go simply said "Of course it will." What I want to ask is, not so much about the above stuff but about our scientific knowledge in general. What is the reason for all this certainty and rejection of doubt? Is our grasp of science that good? When we know something do we really know it for sure? Or is it something else? Are scientists today too sure of themselves? Is everyone taking their word as gospel? Do people talk as if things are facts because they want to sound convincing? Do documentary makers simply assume we will know they are not talking about absolutes even though they never said they were? Even though they implied everything they said was fact over and over again? I read somewhere that we might be living in a new dark age, because we don't think to investigate what our "higher ups" tell us. The only things scientists are really certain about is uncertainty. That may distinguish them from faith.
