A bird is flying around and gets blown by the wind. He doesn’t know why. We could try to explain to him that hot and cold air cause differences in air pressure and when the air in an area of high pressure is forced toward an area of lower pressure wind ensues.
But I doubt he’d understand that.
We could try to explain to a cat that when she’s walking around and waterfalls from the sky and gets her wet, it’s because of processes like evaporation and condensation, but once again, I don’t think she’d understand.
The brainpower of birds and cats have limits. But we believe we’re different. Given enough information, we believe we have the ability to understand everything. Is it reasonable to assume that every other creature on earth has limits to its brainpower but we don’t? What evidence is there to support this?
Until recently we thought we knew what the world was made of. It was made of matter and energy. Matter constituted everything of substance – stars, cars, water, electrons, quarks. And energy was divided into four types – gravity, electromagnetism, and the strong and weak nuclear forces.
But now we’ve discovered (by “we” I don’t mean you and me. I mean people a lot smarter than you and me, like astrophysicists) that all the matter and energy we know about probably constitute only 6% of the universe. That means we have no clue what 94% of the universe is.
We call it “dark matter” and “dark energy,” and we assume it’s some undiscovered manifestation of matter and energy. But we’re just guessing.
There are two possibilities. It is possible that we just don’t have enough information to understand the universe. It is also possible that we don’t have the brainpower and will never fully understand the universe.
I believe it’s probably both. The universe may be way more mysterious than we think. And our brains may be way less perfect than we think.
