1. – So we may live in a one dimensional spaghetti universe full of gas

2. I rewatched this more than Donnie darko

3. i would support you, but i have nothing in this world except the ability to comment. keep up the great work!

4. I totally understand what he's saying…. Yeah😅

5. Im learning dimension than learning school

6. Well minute physics, a cube does not have as many points points as it’s side, it has more. Using the axiom (schema) of specification, a cubes volumes (A) contains all points of it side (B and part of x) so a cube contains more points than it’s sides.

7. I’m so confused

8. Which editing app used??
   Its awesome

9. Just so your brain doesn't hurt:

   0D: (not in video) a dot

   1D: A line

   2D: multiple lines creating shapes

   3D: multiple shapes folding to create stuff

   4D: (not in video) hell

10. My teacher:

    Me: stares into space

11. Im dying bruh, I only thought they were only 2d and 3d because there’s 2d and 3D characters and games, but I just realized there’s less and more than 2d and 3d

12. An intelligent flat earther cool I'm still round tho

13. i liked the last bit lol

14. Zerooo understanding.. My 🧠 shut

15. What about 4D

16. 3d cuz 3rd planet

18. I'm binge-watching minute physics lol

19. 0:46 "A Big Ass Cloud"

20. Actually a 1 Dimensional is actually a 2 Dimensional, so it self-collapsing, meaning it's non-existant

21. 4d 2

22. Omg 1D!!!! Can i get Their autograph????

23. Speak slowly or otherwise give subtitles 🙂

24. Could it be that our definition of volume contains some kind of bias that gives us the illusion that the volume is 3-dimensional rather than 1-dimensional? Could it be that since we created Mathematics in a seemingly-3-dimensional world, we cooked up mathematical definitions to conform with our perceived illusion?

25. 0:23 How do a square and its sides contain the same no. of points though?

26. Who came here to see if we can survive in a 2D world

27. No…. no…
    No…

    That's not how space-fillling curves work…

    The cardinalities of 1D and 2D space (finite or infinite—they're the same) are the most basic examples of "this infinity is biggger than that infinity"… aren't they?

    Have I beeen wrong alll my life?

    Can I @3Blue1Brown or something?

    I'm so confused…

28. Okay but what is the third factor in the third dimension? What does z equal? This doesnt feel like it should be so hard to find.

29. wait what did you say?

30. Actually you can't give a 2D (or 3D) position with one coordinate on a square (or cube) filling curve, because except the origin, all points are at distance infinite from the origin.

31. 3
    Dicks

32. Basically imagine 1D being a line/radius, 2D being the whole circle (because it’s squared), 3D being a sphere because the radius is cubed, and 4D…. idfk.

33. How many dimensions would tits be

34. You just made me Dumber thank you. I was already dumb

35. Gutes video

36. earth is technically flat in 1D

37. But can we do 1 or 2 coordinates continuously?

38. Does that mean that something 1-dimensional has a infinitely small second dimensional lenght/width (idk how to call that) or that they have none such thing and their second dimensional width/length is 0?

39. The first channel that I have nothing understand in it in each video and every word😂😂😂

40. I do this
    1+1=11
    1=2
    48489494=1

41. What? Please explain like I'm 2

42. This isn't relevant at all. Honestly.

43. I don’t understand a thing he had said

44. Too fast

45. What if we are just in a 3D which is in a 2D which is in a 1D which is in a 0D and then that 0D is in a 1D which is in a 2D which is in a 3D which is in a 4D which is and which is and which…

46. Yeah yeah great ( WTF did he just say?)

47. If something is so curved it looks 3D what about a ball it's even more curved
