Can those outside of science credibly speak about science?

Since science is simply a way of looking at things, anyone can talk about the value of the aproach or give thier opinion on it.
If you speak in terms of specific fields and the factual findings one may become familiar with, in that light....no..those who deal with the facts they find are more aware of them.
How those facts are interpreted is another thing. That is why theories are born. A theory is simply an "educated" guess.
So one can take the view that one persons educated guess may come with a bit more insight than anothers. But we know in life this is not always the case. If fact throughout history, far more theories from those who follow science have been inorrect than those proven true. We have a inherant ability to see what we look for.

You have your opinion on the subject and I have mine. It apears to me that you hold "science" with a reverence. As if it is on a pedestal.
I see it for what it is. A tool and nothing more.A theory can be very wrong and misleading. A wrong theory can send the entire science comunity on centuries long wild goose chases. Incorrect assertions are made on a daily basis. Peoples bias work to distort the meaning of facts on a daily basis. How many drugs are being pumped out onto the market prematurely and we are the lab? Science has it's implications both good and bad. We are the falible lynchpin. There is no avoiding that.
A "theory" is only as good as the source. Somehow you have mistakenly elevated the idea of a theory beyond the falible capabilities of the source.

Well....we talk about the universe and big bang. What we fail to convey is that this theory only attempts to describe what we can detect. Not only might the theory be wrong but in no way should we assume it is the beginning of everything....provided there was a beginning. That is a human mistake.We do like things in boxes we are familiar with. In the end science means nothing. It is what we do with what we learn that will bring meaning to it for us. That is what matters in the end.

Well robinrohan, you must answer that one for yourself.

My view is that once you have entered the limits of what is known there are no experts. There are those who's educated guesses or opinions will tend to have more insight and therefore either be more likely on target or simply trusted. To simply trust the opinion is a mistake.
I find by reading many posts on here that we are all biased based upon our personal perspective.
