Our knowledge of what we see is changing. We now see that atoms and stuff only make up 5% of reality and then there is dark matter. The Large Hadron Collider tells us about it. All this until we discover another particle. Now we also believe there are more than three dimensions. Maybe we will offer though a place in reality and describe it as a dimension. It’s an interesting time to be alive.
Science is taking off. We are truly becoming global with the likes of CNN, BBC etc and going beyond parochial meanings. It’s a profound time to be alive. I think humans can be more accepting of the differences in people today. Probably time travel will be next, just a conversation with my future self, beam me up Scotty.
