What Does a 4D Ball Look Like in Real Life? Amazing Experiment Shows Spherical Version of Tesseract

Okay, everyone, today I'm going to show you

what

a

ball

would

look

like in a fourth spatial dimension. A four D

ball

. So I'm going to show you

what

a sphere would

look

like if there was a fourth spatial dimension. And then what would it be like if there were a four D being? That was going to move that sphere through the fourth dimension. What would it look like in our 3D space? And what other cool things could they do if they moved things and 4d? What would it look like in our three dimensions? We then live in a universe that has three spatial dimensions.

That means you can go this way. You can go this way and you can go up and down. For example, I have this cube here in three dimensions. But what would it mean if you just looked at this cube in two dimensions? Well, because we only have two dimensions. It means that we can only go from one side to the other, but not from top to bottom. So is it the equivalent of taking a portion of this cube? So instead of having a bucket now, I take a slice. Now this is simply called flat. It has the x and y axes, so it has these spatial dimensions, but it

does

n't have up and down.

That means that when you look at it from the side, all you see is a line. So now We have a world that has only two dimensions. What would a sphere look like in these two dimensions? Well, because everything in two dimensions is just a slice of three dimensions instead of a sphere that has up and down. You would only get a portion of that sphere. So a sphere would now look like a circle. So the first thing I want you to notice about this two-dimensional circle. Is that to me in three dimensions looking at this two-dimensional plane?

I can see the full circle at once. I see everything, inside and outside, all at once, but for someone who lives in this two-dimensional world, they don't see a circle, but they see a line. Can you see what? I mean, I start from the top and I can see the whole circle, but as I get to the plane, that circle gets smaller and flatter and flatter, until it finally becomes a flat line. So, if these two-dimensional beings live only on this plane, the only thing they see are lines. So what would a sphere look like to this two-dimensional person?

Well, remember that that two-dimensional person can only see a portion of the sphere and will only see it if it is in their plane. Anything outside of it, it can't see, it only sees what's on this plane here. So in order to see this, I would have to move it to the plane, but how it would look from your point of view, it would be like a circle suddenly appeared and then got bigger and then smaller and then disappeared, and then I was a being. three-dimensional by moving this 3D object across its two-dimensional plane. It would seem quite mystical, it would seem that things suddenly appear and then disappear, appear and disappear and with that in mind we can now begin to understand what it would be like for a Four.

Four-dimensional being to move a four-dimensional object through our three-dimensional space, so I'm going to show you what it would look like if a four-dimensional being moved a 4d sphere through our three-dimensional space. similar to the two-dimensional circle that starts out small, gets bigger, and then gets small again. But it would be in three dimensions. So it looks like this, okay, here's my four-dimensional ball and what you're actually seeing is the tip of the four-dimensional ball. This is the little circle. But since we're in three, it's the little sphere at the tip of the ball. four-dimensional And I can move it and do whatever I want with it, but look what happens when I call upon the powers of a fourth-dimensional being to move the ball through the fourth dimension and through our 3D space.

Well, it would look like this. Well, they're moving it through the fourth dimension and as he moves it it gets bigger and bigger and bigger and stop. Now you can see how he moved through the fourth dimension. The size changed in our three dimensional here So now we have a larger sphere but we are not quite in the center of the four dimensional spheroid. So let's leave it and have the fourth dimensional ray move it through the largest diameter that appears in our three dimensions, okay? , and come on, now it's moving, moving through the fourth dimension, which causes the spear to get bigger and bigger and bigger and our three dimensions.

Until we finally finish this. So now the four-dimensional sphere oeid has its largest diameter. and our three-dimensional space and now I have a very large sphere, so we know that a four-dimensional being could suddenly appear and then disappear in our three-dimensional space could cause objects to randomly appear and disappear. Change shape completely and it would seem quite mystical, but here it is. something even stranger that a 4th dimensional being could do. They can turn you into your own mirror image of yourself. Let me show you what I mean. Going back to our two-dimensional analogy. Here is our two-dimensional boy.

Now suppose in this two-dimensional world. He is looking at this object. There is also a mirror behind us. So this line represents a mirror. So, looking in that mirror, the reflected image looks like this. But no matter what you do in this two-dimensional world, you can't make this object look like your mirror image any more than just looking in the mirror. But I, as a three-dimensional being, can go in and take it out of this two-dimensional world, turn it around. And now it becomes a mirror image of itself, because I was a three-dimensional being and I was able to take it out of this two-dimensional world and flip it into my three-dimensional world, now this is permanently the mirror image of itself for this two-dimensional person now.

So the same can be said from three dimensions to four dimensions. That means this fourth dimensional being could take this pretzel bag and flip it over in the fourth dimension. And now he would permanently be a mirror image of himself in our three-dimensional world. In fact, you would never be able to hide anything in our three-dimensional world from a fourth-dimensional being. Everything would be present at the same time. You will immediately be able to see what is inside this box. Similar to how I can instantly see what's inside this box, but this two-dimensional person wouldn't be able to see it because it's blocked by the outside.

So it would be pretty

amazing

to see something from the fourth dimension moving through our three dimensions and making things reappear, change shape, do all kinds of different things, even creating mirror images of things. But is there a fourth dimension of space? Well, actually there might be string theory that suggests there are 11 spatial dimensions, but only three of them are big enough to notice. So we have three spatial dimensions that are large enough to see any changes, but the other dimensions are not large enough to notice any difference with movement. Hello everyone.
