4th Dimension explained

1. but can you turn a sphere inside out?
2. why are d vertices meeting at a pt
3. This was 100000999999999999999x more usefull than the video I just came from (turning a sphere inside out)
4. As 3d objects, there must be a reason for them to continue to exist, and that is through time, the fourth dimension.
5. interstellar world is here....
6. my brain hurts
7. Working on the 24th dimension. The other 23 were too confusing, so i gave up.
8. flat-earthers still live in 2d.
9. that was too slow explanation
10. My point is that you can't describe 4 dimension on 2 dimensional screen :|
11. Just a small note, you could describe the position of many points in n dimensions by one number. If it's x1, x2, ..., xn coordinates are all natural numbers, then writing the prime numbers in order as p1,...,pn then you could write a number p1^x1.p2^x2. ... .pn^xn uniquely describing the position of the point. For instance if a point in 3d was at (8,2,10) you could write it's position as the single number (2^8)(3^2)(5^10), which is unique.
    
    All I'm saying is, it is incorrect to say a point is in n dimensions if it can be written as n numbers, it would be better to say we have an n dimensional space if it can be spanned by no less than n perpendicular vectors
12. Wait so we're in the 3rd dimension and our shadows are 2d so would shadows in the 4th dimension be 3d? My brain hurts now
13. Narrator's voice is so sleepy, I can't fully concentrate
14. There is no 4th dimension.
    
    Everything could be simply explained if there was an ether through where light waves.
    This is tested ONCE, by checking if light moved faster towards the east, and slower towards the west at noon.
    And since it didn't differ, we concluded that there couldn't be an ether, and thus light had to be made out of photons.
    
    The mistake:
    If there is an ether, it'll be gravitationally bounded, as we see in a light mill, and around stars.
    Therefor, the ether will fly with our earth, and thus light can wave at the speed of light in any direction on earth even when the earth itself is moving.
    
    Conclusion:
    Time isn't relative! Distance is relative (relative to the gravitational bounded ether)
    
    Sorry guys, no time travelling! Ooooooh!
    Science still interesting enough?
15. My brain is exploding
16. I used this video as ASMR. sorry
17. Is this how LSD was made? Laughing more and more!! XX
18. so 4 dimensional objects create 3 dimensional shadows?
19. why do you keep mentioning reptiles
20. LSD.
