Isn’t the 4th dimension time?

"What's there to stop us from imagining a world with four, five.. dimensions of space..." My brain, which already hurts... But let's try anyway

I’m convinced that she’s actually a 4D being pretending to be one of us to educate us

[jessicas.]

I went down a rabbit hole of thought when I first realized shadows in the fourth dimension must be three-dimensional. I was up until 3 or 4 am trying to understand what that might look like 😂

She could tell me that my dog was on fire and I’d probably just sit there and listen with a smile on my face.

I believe this lady is not from our world but a higher interdimensional being that looks at our race as small children

If you imagine a 2-dimensional egg as simply an oval with a smaller circle inside which represents the yolk, a 3-dimensional human being can simply reach into the 2d egg and grab the yolk, without breaking the eggshell. This would be unfathomable to a 2-dimensional being, who can't even see the 3d human grabbing the yolk, because there is an intact 2d eggshell blocking the action from being observed. Also, a 2d being probably can't even imagine a 3rd spatial dimension.

It'd be the same if a 4-dimensional creature removed the yolk of a 3-dimensional egg. We wouldn't even be able to see it happen. Just like the 2d creature from the previous paragraph, this action would be unfathomable to us 3d creatures, as we can't imagine a 4th spatial dimension.

I understood everything she said.
My dog also understood everything.
We both are very sophisticated gentlemen.

It's puzzling how infrequently people clearly explain this. Thank you.

[tordjarv]

I think Cixin Liu describes how a 3D creature would experience a 4D world really well in his book Death's End. I would strongly recommend reading that one (but you should read The Three Body Problem and The Dark Forest first).

[ClearlyPixelated]

I appreciate you having "explain to me like I'm five" videos. These are great!!❤

[muralisaripalli]

Your shorts are incredible. Please don't stop

[codswallop]

If you're interested in this idea, I highly recommend the novel "Flatland" by Edwin A Abbott. It's very old-fashioned and all the more interesting for it.

[blackbeardsghost]

Imagine a voice, so soothing, so calm, and so convincing, that anyone could imagine whatever they are told to imagine.

Cartoons need to be draw about this woman teaching classes on a magic school bus.

[garyloewenthal]

Thankful each day that the 4D people have not ripped out my internal organs and have limited themselves to socks and twist-ties.

The idea that time is "THE 4th dimension" is a common misconception. It is considered ONE dimension of our reality, but not necessarily "the 4th". Time is arguably the only other dimension we can observe next to the 3 spatial dimensions we know, so from that point of view, it is the 4th observable dimension to us. But like she's saying, there could be a 4th spatial dimension that we are unaware of, the same way a two-dimensional being would be unaware of beings in the third dimension.

One of my favorite quotes is "Whoever discovered water, it wasn't a fish". We identify water as it exists relative to everything else. Water is simply one thing of many on our world. But to a fish, water is merely the "space" they exist in. They don't know anything other than water to compare it to. They can't see outside of their pool to realize it is just one small component of a much larger picture. That is us in our universe - we can't look at it from any other perspective to see what it is relative to anything outside of itself, because we are IN it. We could be swimming in a big "space puddle" and not even know it.

Taking the yolk from the egg without breaking the shell is one of the coolest ways to introduce higher spatial dimensions 👍🏻

[BillyOrBobbyOrSomething]

4th dimensional me is stealing her heart rn so she can existentially terrify me for eternity

[Peter_]

The 4th spatial dimension is a dimension that allows movement between different spaces - for example, you could walk through a wall if you left this particular space, then walked forward in a parallel space, and then came back to this space again. This would probably look as if you faded away into nothing, and then reappared out of thin air.

[herbderbler]

Now try to imagine multiple dimensions of time.
