So sorry, I hate this part of the discussion...
Ok, so lets say we take our brain, simply speaking how has evolved to not only survive in our world but how it has evolved to bring about language and much more advanced ideas such as curiosity, self awareness, etc..
But lets imagine that our brains exist int he matrix, for a lack of a better example. The matrix is our planet, we see plants, we see other people, tides go in, tides go out, no interruptions....
Our brains have evolved within this construct, we see for example a clear start and beginning to life, we see clear definitions of solid and not solid, we can explain things in relation to experience.
However, now we have reached some rather difficult points of our understanding, which is where quantum mechanics comes in. Ideas like, a universe from nothing, no beginning or end, time is a construct not a constant, etc.. These are very difficult ideas for our brains which have developed within a frame work of our very isolated and very small home on earth, which is a speck within a speck amongst a beach of sand more massive than we can imagine, and then x1000000000 to that which you can imagine.
Sorry just babbling, physics is the most fascinating field of research and I get all giddy considering its ideas and more importantly its consequences.
