Well we don't even know what size wheels to use on our bikes or even what tyres to put on them so I feel we are some distance from total knowledge
People can spout what they like about quantum physics hailing it as the absolute truth
No-one who understands it would ever say that!
Nice question. Just the other day I was discussing this with friend. She does not believe in life after death and she said that people who believe in something bigger than us are just gullable. She meant that if there are things we cannot explain it's just because science hasn't found the answer yet. If, for instance, people born in the middle age suddenly saw something working with electricity, they would probably think this is a miracle, but today we know there is an explenation to this. The same with everything else in the world. So basically, yes, there are people who firmly believe science will one day find all the answers. I am personally not really sure, to be honest.
most of the things it currently 'explains' is just a best guess model
Yep, scientists don't do certainties, you need inveterate gamblers and the religious for that.
of course there's often a hell of a lot of evidence for those best guesses.
Love that einstein quote.
There is a theory which states that if ever anyone discovers exactly what the Universe is for and why it is here, it will instantly disappear and be replaced by something even more bizarre and inexplicable. There is another theory which states that this has already happened.
Douglas Adams
No we will never "know everything" The laws of physics (uncertainty principle, observable universe) make quite a lot of stuff completely unknowable
I'd settle for a good idea of what the other 96% of the universe is though
