You know that a long time ago people believed the Earth was flat, right? Now we’re well aware that it’s more or less a sphere, and it seems ridiculous to think otherwise when there are so many hard facts proving it. But what if those people of the past were actually… right? It turns out they could be, just not in the sense we thought about it. Our brain is a highly complex thing, and science has not yet fully explained how it works. We know, however, that it exists in 3D, meaning that we perceive objects from three different perspectives: length, width, and height. But a physicist from the University of California in Davis, James Scargill, has shared a theory that 2D universes can exist and even support life… TIMESTAMPS:
What are 2D universes 1:05
Arguments against this idea 2:27
We live in a huge hologram? 😵 4:29
What's the shape of our Universe? 5:18
Our brains can easily mess up with us 7:09 #universe #2D #brightside SUMMARY:
– Well, the thing is, since our brain can only think of things in a three-dimensional way, it can’t hold the idea of a two-dimensional space being real.
– Initially, Dr. Scargill wanted to test the philosophical concept that a universe can only exist if there’s life to observe it. – Dr. Scargill did some complex calculations and was surprised to find out that, hypothetically, life can exist in such universes.
– About his other general theory of relativity, Albert said that moving objects with mass create a curve in space-time, pulling other objects nearby towards them. – And Dr. Scargill’s calculations show just that: there could be a gravitational field in 2D space, so the first argument is invalid — theoretically, at least.
– Dr. Scargill argues here that there are planar graphs that have properties like neural networks.
– Many mathematicians believe that our very own universe is two-dimensional itself. It’s called a holographic principle, and its main idea is that the universe is essentially 2D, and it looks 3D to us because its image is overlaid onto a cosmic horizon. – Let’s go back in history and meet our ancestors, the ancient humans. You know cave paintings, right? If you saw them, then you realize that ancient artists knew nothing about perspective. – The people of the past naturally didn’t want to adopt new and radical ideas about our world, and they preferred to see it as flat. – Our brains can easily mess up with us. The thing is, whatever we see, hear, smell, touch, or taste is not really an actual object — it’s our subjective perception of it.
– So many humans, so many views of the world. And there are literally no two worlds that are completely identical. This is just crazy, but it kind of makes you believe we could all be living in a two-dimensional space, only seeing it as 3D.
