fourth spatial dimension

1. Trying to visualize a fourth spatial dimension is interesting, but I think impossible to understand.

To make a rectangular prism you could take different papers of the same size and stack them on top of each other. If you imagine the papers were infinitely thin as if it were truly 2 dimensional, this would mean the paper on top is touching every single point on the other paper. To an imaginary 2d being they would not understand how the points in the middle of one rectangle can touch the middle point of another rectangle because they can only think about moving the rectangles foward, back, left, and right. It would seem completely impossible. If someone showed them you can just move the rectangle "above" the other one and put it on top they would be amazed.

So to make a 4d version of this rectangular prism, somehow you would have to have a way for a cube to touch every single part of the other cube including the middles. Just like the 2 rectangles when 1 placed on top will have the middle of it touching, the 2 cubes would have the points in the middle of them touching each other.

Does this mindfuck anyone else?

2. I read that whatever dimension ur in, you can only see things in the previous dimension. For example imagine a cube, we're in the 3rd dimension but we don't actually see all sides of the cube (front/back, left side/right side, top/bottom) we see the... okay fuck this dimensions are confusing

3. I think I just got mindfucked

4. Yeah that is also true. If we were 4d beings, we would be able to look at "3d spaces" the same way we look at a 2d painting. We can see every single speck of paint in the 2d painting so as a 4d being we could see every side of the 3d objects in 3d space including the inside of these objects.

For example, you could think of a 3d painting as a "room" and you can see everything in it, including the inside mechanics of your desktop computer, the front and back of the computer monitor all at the same time.

I think this is why we can't imagine the 4th dimension. Its too much information to process at once.

I just wish I could imagine a simple 4d shape haha, it would be kind of cool. To visualize just one side(or would it be a "3d space" since 4d haha) of a tesseract you would have to visualize the 3d shadow version of it. And to truly imagine the 3d shadow you have to see it rotated completely to see all sides.

This still doesn't help visualize what direction the new dimension is, but I guess you just have to accept that it is somehow exactly 90 degrees from our 3dimensional space.

....mindfuck

5. Cannot compute

6. Just out of curiosity, not a conspirasist here, how can the 4th demensions and up be proven? If we can never visualize/truely understand a higher demension, then how is it a generally accepted idea? Surely there is proof. Educate me

7. Actually I don't think there is any proof. I believe we theorize there are infinite dimensions because we believe space is infinite, therefore why can't dimensions be? What limits them if they are limited?

Also I believe the string theory requires 11 dimensions at least to function properly (I know even less about the string theory then dimensions, so some of this may be incorrect) however that's not proof in itself because the string theory itself is a theory that we can't prove until we have much better capabilities. Oh and for those who don't know what the string theory is, is that its the theory that all energy and matter in the universe is just a string, and depending how it vibrates will depend on what type of energy or matter it is. However these strings are so small we can't prove there existence. Again I may have some incorrect knowledge here, because I haven't heard much about the string theory for the last few years and am going on old memories.

8. Did you guys watch the Adventure Time episode with the 4d bubbles? Basically, a 2d bubble would cast a 1d shadow, a 3d bubble would cast a 2d shadow, and a 4d bubble would then cast a 3d shadow. This concept could help aid us in our search for a 4d shape.

9. When we sleep I think our mind and consciousness connect to one of the dimensions and that's where we dream, because dreams are not from our mind, you can see things you've never seen before and explore new worlds, and it's fun when you're a little awake and can do what you want. Flying is my favorite.

Fucking awesome. I had no idea he did more of those[/quote]

Yea he got into describing each one..he comes out with new videos pretty often too..rob is a cool guy and it's crazy how so many of his theories are the same as the ones I come up with (mostly while high and on other things lol) and he says he's never done drugs

12. Damn dude. Does he post all of the videos on one channel that I can just sub to?

Yea it's 10thdim

Thanks a lot dude.

15. I'm really fond of the illustration beginning with a dimensionless point and moving it in some direction to form a 1-dimensional line, then moving the line at right angles to itself, create a 2-dimensional square. Moving this at right angles to both previous directions forms the 3-d cube; by moving the cube at right angles to all the familiar axes, some direction we cannot point in, generates the 4th dimension; at this point in my imagination, the universe suddenly rips away from the object, but this visual is very far from any actual conception of what it would be like.

Can you explain in detail how you draw that. I wanna give it a shot.. Sounds interesting!
