How can we be sure this is reality?

[Brian37]

So if you don't disagree with me then what do you think I am missing? Science, especially QM suggests weird things? Yea, but it will never make fiction or si fi real or invisible beings real. It also will not make the universe itself a thinking being.

Still failing to understand why people are trying to turn "you don't know" into "therefore" propositions.

We can rule out allot of crap without worrying about the future. That is all I am saying.

No, you miss the mark again.

In order to model reality under the scientific method, observations of our perception of reality are used. But are those observations of perceived reality consistent with actual reality? I don't know, and you don't know either. Prove it, and there's a Nobel prize waiting for you. We assume that our perceptions are of reality (backed by the perceptions of others and the peer review process), because to assume the reverse would be both absurd and not useful to explain anything.

That I understand this, and you seem to not, does not mean that I think science is a bunch of assumptions pulled out of our collective asses.

So we are not in disagreement. I don't think science is a bunch of assumptions pulled out of a scientists ass either. So what is the problem?

I think maybe you are getting semantic.

But are those observations of perceived reality consistent with actual reality?

That's why scientists test and review. It allows science to adapt to new and better data.

Again, not knowing the future does not mean we cant use a trash can when we come across bad data, nor does it mean we should assume the future just because we dont know the future.
