What are higher dimensions?

[@luckyluuk_0876]

Can we just appreciatie how professional this is, even though this is her first (long) KZbin video

[@modernday_eratosthenes]

Thank you!! It’ll get better I swear

[@ronanfitzpatrick1261]

Personally I'm her because of her TikTok videos which are every bit as good. Should be used as example to anyone who wants to discuss complex topics for a general audience imo

[@arabian800]

What are the odds of me randomly wanting to check on the modern day Eratosthenes’s shorts and find a KZbin VIDEO ?! Perfect

[@CountD42]

Random side comment: The tesseract scene in Interstellar was filmed mostly using practical effects on a massive soundstage. I highly recommend looking up some behind-the-scenes photos of the set.

[@JesusChavez-lx2bx]

so happy to see you here, Ashley. it feels a little different than TT, but I like the change. Now, you moved form my living-room (on TT), to my office (YT). Welcome aboard! :)

[@Tweepx]

Woohoo! Happy to be here for the first longer vid! :D You can also put a big light behind you, pointed at the green screen, to get less shadows showing up.

[@wizarcovhd]

This is a really nice video! Good job with the editing and format

[@taruhmei]

love the way you explain complex things, learning like this feel so comforting and healthy.

[@gammawray]

I'm always fascinated by that clip of Carl Sagan describing a tesseract. Happy to see you in a new format!

[@masonvega]

Great new video! Glad you're on KZbin! I always imagined that dark energy exists because whatever higher-dimensional thing the universe is sitting on may be spinning, so our distant galaxies are nothing more than marbles on a spinning record player. This has cost me a lot of sleep...

[@sergioluiz4000]

I loved the video format. Keep up the good work! Congrats on coming to KZbin 🎉❤

[@brianjacobs2748]

5:50 there are good representations in video games, like 4D golf and 4D miner. They give a good intuitive understanding of 4D space by allowing you to explore it.

[@PrettyDancingPhonics]

Brilliantly and engagingly explained

[@theendoffaith5903]

Congratulations Ashley 👍 I love the long format now… the only thing I miss was your laugh 😆

You are such an incredible science explainer! These videos are great and you should be on TV for people/hopefully your channel gets huge.

[@aleksanderatanasov605]

You are legit inspiring me to pursue a science degree. You are so amazing ❤❤❤

I have been trying wishing for a long form format since the early days of tt. So glad you are doing this!!

i've never seen your content on tiktok i just saw a youtube short that brought me here from a podcast

[@EthanDonovan-q9t]

I actually cannot explain how much this lady has educated me and has brought joy to my life

[@mazilliusmashupgunz318]

No idea about the maths of higher dimensions, but particles like elections pop in and out of existence from our perspective. Like in the LHC. Could higher dimensions explain that. What about quantum entanglement? Could that be particles connected via higher dimensions and we just see the intersection with ours. What about quantum tunneling appearing to us as faster than light "travel"? Whatever, this was thought provoking. Thank you. You do a great job and are so entertaining! Love the humour too!

[@indigomontoya1970]

Well done. I can explain it to others, understand it,& see how it works.

[@gosnooky]

Love the longer form video

[@Astristul]

The shadow, behind you, is kind of disturbing! But, other than that, it looks pretty good, for your first YT video. As for the content, very well made. Keep'em coming! 🙂

[@nickymalara]

Quick tip... You have to put your face on the thumbnail, For the people that have seen you on TikTok, but don't know your Channel name. BTW, Love the long form content; you will do great here.

[@modernday_eratosthenes]

Ugh I know. As odd as this might sound, I hate pictures of myself. So idk how I’ll get around that one

Where is the tutorial on how to fold that paper box? I think that is the most crucial question after watching this video!

[@regallux6973]

Saw your tiktok talking about editing came to KZbin to check you out but you had no long form Vidoe so I sub to get notification for this Vidoe lol cuz you said it was hard editing I love the knowledge don't stop out more long form am here for it new sub here

[@Jhoffa22_]

About damn time I got more of your gorgeous self Ashley, Appreciate the long upload and hopefully there's more to come after this...😘🤩😘

[@aaronsnyder9961]

I feel like there should be a conclusion or a summary at the end it to me at least felt none existence to me at least bit other than that it was good

[@ChrisSherbak]

Ya, a "here's what we learned today." And I'm so used to the obligatory "if you like this video - give us a thumbs up and be sure to subscribe..." - I kinda missed it. One nit to pick: the drawn circle is not two dimensional as the paper (and ink) have thickness so it's really still three. Also maybe some 'further reading' and pointers to books etc. 'Flatland' seems VERY apropos here. But yes, very good. GO GO ASHLEY!!

[@8elbowsAdventures]

I am thoroughly confused and delighted 😁😁 if time is the 4th dimension.... and time and space are ... linked? i.e Space time... Could there be other dimensions of time? ... or is it just more space... or more time?

[@Howyadoin1]

This was such a good video

[@Ksbshsiowoebxmosugvwhxy]

Loved it❤❤

[@iuks2185]

Hey, welcome to youtube longform! 😊

[@HaHa-gy5vg]

A tesserect has eight faces. Each face is a cube. Just as a cube is six squares that enclose a volume. A hypercube is 8 cubes enclosing a 4D volume. So as you could roll A dice with a different face coming up. You could roll a hypercube And a different cube would face you.

[@brianjacobs2748]

they are called cells and each of those cells have faces and each of those faces have sides and so on

[@E3N_Bierski]

What about when you face 2 mirrors toward each other and the image repeats deeper?

[@waltersumofan]

combine this with your recent vid on polarized glasses, can we try to polarize ourselves into the 4th dimension? Force a 90 degree perspective on ourselves.. dunno, would make a good movie plot though :D

[@waltersumofan]

other than Buckaroo Banzai, of course

[@Jaggerbush]

So a "line" has neither a beginning or end? A ray has and end point at one end (beginning) and a line segment terminates on either end, but a line is infinite on both ends? Neither a beginning or an end?

[@Queen_W1-s7o]

Love the video

[@pikiwiki]

my complaint is, if a line is visible it has to have depth owing to the material that the line is made from- be it pixels or ink- so- isn't the line three dimensional and not two dimensional?

[@ClioinAlexandria]

As someone once said: You light up my life.

[@ssnakesv]

[@peterv7258]

I feel like a circle is just an infinite number of connected points, and therefore a line segment, and therefor only one dimensional, it's just a dimension that curves instead of being straight.

[@Qermaq]

1:55 A circle is one-dimensional. A disc is two-dimensional. The circle is the simplest object that is one-dimensional but must exist in a two-dimensional manifold. Just the same, a Moebus strip is two-dimensional but requires a three-dimensional manifold,.

[@lindboknifeandtool]

Would a fourth dimensional object appear as a point for a third dimensional being? Or invisible?

[@Viewpoint314]

What kind of brain would be required to actually visualize higher dimensions? Would we require a higher dimensional brain like a 4D brain to visualize 4D?

[@istvanrabrady9160]

awesome!

[@TexasGreenthumb420]

Not the first comment but not last one either. You're rocking this!!

[@MotherShipMedia]

Aren't we technically 4-d beings? We exist in the now in 3-d, but our existence is traced with a start and end point in the extra dimension of time as well, so we trace out a 4d shape in spacetime ultimately, right?

[@TheEllod]

Mathematical dimensions are just qualities you want to analyze together( usually both modelled by the same system of numbers often real or complex numbers), they do not have to be physical dimensions, that is a physics mental bloc...not mathematical one, kinda like how causation is a time dependant things in physics. This video had some good info but was also made from a perspective lacking in contextually relevant understanding of math, mathematical modelling and methods of legitimacy in physics and math.

[@peterv7258]

Also, it really seems like one- and two-dimensional things are not even real. They are merely directional concepts, not physical realities. Everything in physical reality is 3 dimensional, at least every material thing, and space, which is somehow also a material thing. But direction isn't a "thing."

[@kopkaljdsao]

It's where physicists put all the math that doesn't make sense.

[@vincaalkaloids6732]

Wow...I mean...wow.

[@resilientfarmsanddesignstu1702]

We are just the 3-D shadows of our 4-D selves. Just as our shadows are 2-D shadows of our 3-D selfves. Just as the edge of our shadow is the 1-D shadow of our 2-D selves. Just as a point is the 0-D shadow of our 1-D self. What is the shadow of our 0-D self?😮

[@Ytbinger]

YAYYYYYYYYYY LONGFORM

[@sakis421147]

I loved the video and think you could go even longer. Your "format" doesn't get any tiresome at this length and those little comic relief moments can keep it from getting tedious. Just my personal opinion though! Cheers

[@JoshVandever]

Speak for yourself. Just because YOU can't, doesn't mean every one can't...

[@renevw5812]

If we look at dimensions most kids get explained that 1D is a line. Now, that is completely wrong. If you take a line and look at this line under a microscope you see a beginning and ending. So looking at a line you already looking to that in 2D. To explain 1D in the purist way is a area that never has e beginning and ending. With 1 D in a 3d world with 1 ligthing source has 0 shadows. Now for kids to explain what 1D is and draw a line, it is fine. But thinking and begin in a 1d world that would mean that this area can only be explained as never has a beginning and ending. 1d gets more meaning in a more dimension world. The 3d world we experience only can be real with the help of 1d and 2d and 3d. Another fact: If we have 1 light source. 1D have no shadow, 2d has 1 shadow and 3d has 2 shadows. So if we ackknowledge this constant, can we also say that 4d should have a 3rd shadow? Now, if we have no light source we still can experience a 3d object by touching for example. But a light source gives us information that we can use. How do you think about this?

Respectfully there are several half-thought-out metaphorical statements used in this video that i think lead only to more confusion for a newbie... i dont think this video is a good explainer of anything really... But im not smart enough to explain it any better so ¯⁠\⁠_⁠(⁠ツ⁠)⁠_⁠/⁠¯

[@DimGkelis]

You say that we can interact with objects in lower dimensions, but I don't see how that's true, help me here. We can only interact with objects that have mass, which means they are made of matter, but all matter we know of is 3D. Thus, all 2D/1D/0D objects are purely theoretical for us, we can never see or touch them, just like with higher dimension objects. We do not know of any matter existing in another dimension.

[@LeeCarlson]

You start your video by saying that higher dimensions are "real things" in physics. Still, you have only demonstrated that they are mathematical concepts and not real in any physical sense.
