Nonetheless, the desire to understand reality seems part of our nature, and we have come a long way. What was once explained in terms of divine creation is now in the purview of science. Over the past 200 years or so, we have peeled back the layers of reality, even if we are still not entirely sure what we have revealed.
If anything, the mystery has only deepened. We are now at a point where it is equally credible to claim that reality is entirely dependent on subjective experience, or entirely independent of it. Reality has never felt so unreal.
Lets delve into the latest ideas about reality, from our own everyday experience to the fundamental physics that seeks to describe the true nature of the cosmos. The ideas can be dizzying, but there is no greater intellectual challenge than trying to grasp the meaning of everything.
What is reality anyway?
IT IS a big and bewildering concept, reality. An abstract way of saying “everything that there is”. That is a lot to take in: space, time, matter, energy, forces, consciousness, even abstract ideas. How to even start? …
