The Doors of Perception

I love this.

A couple weeks ago, Financial Times Magazine published a feature by Clive Cookson on Lord Martin Rees: Britain’s Astronomer Royal and an absolutely fascinating man. One quote of Rees toward the end caught my attention:

“There is no reason to think that our [human] comprehension is matched to an understanding of all key features of reality … There may be phenomena, crucial to our long-term destiny, which we are not aware of,” Lord Rees says. This is not exactly a widely declared opinion among scientists, who tend to celebrate how successful they have been at understanding the universe, rather than ruminate on how limited the scope of their study is. But Rees holds this opinion unabashedly, as he describes in a 2012 op-ed in The Telegraph.

And why not? There is no question that science has been amazingly, ridiculously successful at developing an empirical account of our physical reality, but it is still only our physical reality that it describes. Even our most advanced scientific instruments, such as the Large Hadron Collider, are based on a series of theoretical and physical steps out from our basic biological identity. All of science is founded on our experience as primates possessing five(ish) physical senses, inhabiting organic bodies on a wet, rocky planet in three-dimensional space and one-dimensional time. That experience forms what I would call a “bubble” of human scientific capacity.

We’ve been able to do a lot within that bubble, but we would be utter fools to think that we’ll be able to comprehend everything from that basis. There could be principles in our universe—as basic as gravity or matter-energy equivalence—that we have no clue exist, because our brains and perception are incapable of registering them. There could be other dimensions of reality, perhaps infinite in number, existing within and around our own, each inhabited by its own life-forms and intelligences. Our own universe could be nested within other universes, and others within ours, infinitely deep and vast. Continue reading The Doors of Perception
