Max Pucher : Now I know who Agent Smith (The Matrix) reminded me of!

zioxei : "We can go into our houses and do our flat business" :D

Susan Vaughn : A woman in a waffle house over heard a conversation I was having and recommended I watch this video. I sure wish I could have got her name. I would love to talk about this with her. She seemed like a real cool chic. Its not every day sombody just reccomends a video on the 4th demension.

KoyasuNoBara : That's the first explanation of the fourth dimension that I've been able to wrap my head around. It's still completely bizarre and hard to think about, but I can at least vaguely comprehend it now.

Todd Everett : a small mad red head sent me here with a black man with dreds

OneillSG7 : Thanks for a good quality clip of Carl Sagan. Most of the others on here are blurry and, well, unwatchable. At least someone has respect for Mr. Sagan. It's nice to actually be able to have a friend see his face for the first time in a video, instead of backing out saying "nevermind if you can't see who he is". Thank you, thank you, thank you for good quality.

Enaz : who else came here from IGP

KenBoner69 : What's the string music playing

GG mi amico : Igp

Beautiful Ogre : Igp...

Underswap Papyrus : Igp

GeneralGoon : I could listen to Carl Sagan all day.

Replieddawn : Great you just ruined a perfectly good apple

sevan grigoryan : Agent smith from matrix anyone?

edible obelisk : one word ...mushrooms

brigitte george : Brilliantly explained.

Idgarad Lyracant : The First Sermon. Sagan understood the concept of a 'God' better then most priests. If one were to exist, all religions, all interpretations would just be a shadow of it's true existence.

Hunter McNutt : PROTOTYPES

D13 Watchmen : This is exactly what the Bible describes about the levels of the Heavens.

MLKKK - : I knew the earth was flat!

Jace Noto : Time/measurement is@ the 4th dimension

Fauxsyn : So @ 0:46 this is how flat Earthers perceive the world?

Colin Weiss : time is a flat circle...

Luke Eruera : Sounds like Bobby Fisher

JXGaming : I call bs

Adi Sucipto : Dimension, for me, is a human invention; only to limit our thought space. Let's think how God is not limited by dimensions

A. T. Smith : His description of the apple and the flat square reminded me of Dr. Strange's "trip" but what really was fascinating was learning that a tesseract was real entity.

Brennen Cox : I swear, it's because of videos like this, flat Earthers exist...

Peter Boone : I saw a girl on tinder who had this as her bio. But you can't copy links on tinder, so I had to type the URL in one letter at a time. So if you're reading this, hi Margaret.

Derrick Duan : can you not keep sexually assaulting me with your deep voice

Dimethyl Tryptamin : If we had a better concept of time, then maybe we could be able to explain the 4th dimension.

Los Overwapos : is this from cosmos?

Adrian&Liz2035 : Stranger Things show brought me here.

Novarius Haze : This is cool. I liked how he explained the 4th dimension. Makes a lot more sense now. Thanks IGP for the link.

Slade Areola : soooo, is he saying that no matter where the light is, is it just the same angle, height, width and length

Mark Van Gorkum : Now I'm even more confused.

jamesdavid3 : I think the 4th dimension will be outside of "Space" we just need to get there

Циани Сундерлин : I wonder how high he was during the making of this video.
