That's a non-issue. Everything you've ever experienced is mapped through your perceptions, and thus it's all illusory. Physics is about coming up with language that describes our experiences accurately, not distinguishing between meaningless philosophical inventions.
- danbruc 11y agoEverything we know about the world has at some point to go through our senses but it is still a reasonable assumption that there is a real world outside and independent of our minds. When we collide particles in an accelerator and then look at the results on a computer screen you can hardly argue that our vision disturbs what the experiment tells us about the world out there in any significant way. The whole goal is to learn things about the world out there in a way independent of us and that is certainly possible. Relativity taught us that space and time are really different from what they usually look to us not withstanding that we may have a hard time developing an intuition for them. So I disagree, that our senses and minds have limitations does not imply that it is pointless to ask questions about what the world out there really is like.
