A few days ago I found that I had been watching random YouTube videos about science for over an hour. Via popular entertaining science videos from channels like Vsauce and minutephysics, I had my mind completely blown multiple times. It is incredible what people have figured out, and what we haven’t and especially crazy is figuring out that we can’t figure something out.

I’ll start by sharing a rather interesting, yet surprisingly simple one. How do blind people dream? For those of us with vision, it seems crazy not to be able to see, probably because we always have. The truth is that blind people dream just like they live, exactly like our dreams except for the lack of visual.

A common scientific conundrum is that of perception of colors. It is entirely possible that every person on earth sees colors in completely unique ways. Like what i could see as green, you could see as red, however, we were both taught that the color’s name is green, so we wouldn’t be able to tell if there is a difference. The key to figuring this out might be in our language. As of now, no one has successfully described a color to a blind person. Our language falls short in describing these things, since we have never found a need to be able to describe color. We are all taught that this is red, this is brown, this is green. Imagine seeing the world through someone else’s eyes, and every color was completely different from your own perception.

The same logic can be applied to all perception. We all may perceive time at different speeds, but we don’t have anything to compare it to since it’s the only thing we have experienced. It is crazy to think about the shortcomings of our little minds.

Next up is dimensions. We all live in a three-dimensional world, and we have no way to understand life in a world with different dimensions. For example, the first dimension of space is a point. The second dimension is a line, made up of a group of points. These lines can create a square, a two-dimensional shape. In the third dimension, these squares can create a cube. A cube is a form with two-dimensional figures as its sides. In theory, a four-dimensional cube would be a shape with cubes as its sides. Trippy. As humans in a three dimensional world, we have to way to comprehend a fourth dimension, even though logically we can understand that it is there.

There is a possible way for us to transcend our three dimensions and travel via a fourth, however the experience would require you to be torn apart as you travelled through a black hole. With a reputation of mysterious evil, the enigmas known as black holes has let us know very little information about them. We know that they are the result of stars collapsing down into themselves until their mass becomes infinite, and the gravity created by this infinitely massive point in space pulls in everything around it. However, some think that they may be the openings of wormholes, fourth dimensional pathways between two points in spacetime. Think of it like this, you have a piece of paper with a dot on the left side, and a dot on the left side. There is no way those points can touch because there is space in between them. Unless, that is, you fold the piece of paper, entering the third dimension and connecting the two dots. Black holes might fold our three dimensional sheet of paper and connect two points that have space in between them. It’s really crazy to think about how so simple a concept is too complicated for our minds to handle.

Finally, light is an incredible thing. It is a release of energy, yet it behaves like a particle. It has no mass or volume or substance, yet can be affected by gravity. My favorite part about it is how it’s so important to us and we just don’t really understand it. Electromagnetic radiation, or light, is essentially just little waves of magnetic energy that doesn’t require a host particle, yet it also can be described of as photons(little light particles) that are just little packets of energy. Light breaks the rules, it behaves like a wave sometimes, and other times like particles. Like a wave, light spreads out and dissipates, but like a particle it has momentum and can be trapped by the gravity of a black hole. Light really is a crazy thing.

Of all the information humans know, we still don’t understand some of the most basic aspects of ourselves, of our world, and even our very existence. It’s fun to think about things that our human minds can’t comprehend. Maybe one day we will understand these subjects that currently are beyond us, but we will never know everything, and these might just end up in that category.
