Heath:
People put their faith in science sometimes. At one point in history, science told people the earth was flat, at others that the earth was the center of the universe. And at others, Newton's laws were considered absolute--then along comes quantum theory. People thought time was a constant, never to be changed in any way, and then comes Einstein and the time-space continuum and e=mc2. Einstein himself believed that black holes were theoretical only and could not exist in reality.
So "impossible" to me has no meaning as a general term. It can only be impossible as to current scientific understanding, but until science is absolutely understood in its entirety, I draw no more comfort from those whose conclusions about the "impossible" come from science as those who blindly profess faith through religion that something is "absolute." Two sides of the same coin.
This is sort of one of my pet peeves, when religious people claim that believing a scientific finding is no different from having faith in a religion. The differences are big, and are important. Scientific findings can be wrong, but the important issue is that they are based on evidence. Religious faith is specifically belief about things when there isn't sufficient evidence to support it. Treating the two beliefs as "faith" obscures the very important difference between them (and that, I think, is what people are trying to do when they make such arguments).
Religion and science are not "two sides of the same coin." They are fundamentally different in many ways. While people can have unwarranted confidence in either one, that does not make them the same thing. Key differences include:
1. The fact that science considers evidence critical, whereas religious people tend to view the belief without evidence as as a positive thing.
2. The fact that science
encourages the challenge of previous results, and has repeatedly changed out view of reality as new evidence has come to light, whereas religions tend to view their beliefs as perfect and unchanging, and thus not open to the possibility of overturning. Put another way, scientists consider finding out that we've been wrong about something very exciting and positive, whereas religions view the prospect of finding out that they've been wrong as one of the worst things imaginable.
To say "impossible" has no meaning is a bit silly, in my view. I get what you're trying to say, but I'm sure even you don't believe absolutely anything anyone ever tells you just because it's
possible it's true. But I think this is illustrating Doulos' point pretty well. Someone who thinks scientific claims are no different from religious claims "because, hey, either could be wrong, right?" is going to react very differently to extraordinary claims than someone who thinks some things are so unlikely that we should consider them impossible until we have extraordinary evidence in favor of them.
Finally, "science" never said that the earth was flat, and it's borderline to say it said the earth was the center of the universe. The first was a pre-scientific view, and the latter was over turned about the time that what could really be called "science" started to be practiced (in the west, at least). Not that that's a huge issue for the discussion here, but I think it's important to distinguish between "scientific findings" and "what people believed" and not use the interchangably.
