Being used to how things work in our own universe, one might wonder what life would be like in a universe with only two dimensions. Would things be similar in many ways or would things be vastly different? YouTube channel Sixty Symbols discusses the topic in this terrific video.
A two-dimensional universe simply is not possible. Everything that exists has a (however small) width, length, and height.
However, the video itself is pretty nice. Cool find!
You might want to think about things like the 4th Dimension...
We can't fathom what it would be... but maybe they can see us like we see something in 2D... Everything at once!
Could be. Maybe I just can't wrap my mind around it...
And that's why I prefer chemistry over physics.
