I sometimes come to thoughts relating to how our world looks. A lot of people don't seem to consider the idea that maybe the world is not what it seems. What we perceive of color may not actually be color at all. How we think of matter may not be true. I just wanted potential thought on this. I mean, is it technically incorrect to think that our world is not what it seems? I think this is part of philosophical discussion, so I put it here. The question is: Is the world what it really seems to be? What is some thoughts from the people? Can't wait to hear some ideas.
