So if we are ignorant of time, for the purposes of this discussion, let's use it to represent the 1D world.
Can it function as a place holder because it only "knows" one direction until it is tasked to weave it self through space.
The weave and it's pattern is unknown to time. This can lead to all kinds of speculation.
For example, could our existence be the same as the tip of the needle on a vinyl record or the head of a hard drive. Anyway thanks for the broken brain moment.
It's nice to have a brain break every once in a while.

The shadow of a wireframed Tesseract simply shows a cube from all 3D perspectives at once: Inside, Outside, Left, Right, Top, Down, Back, Front, like the shadow of a wireframed 3D cube on a 2D plane shows one 3D perspective at once.

So how do Flatlanders see one another if there is no surface perpendicular to their lines of sight to reflect light back to them? Maybe I’m being parochial in my concept of sight?

I see a prime example of why people think they see weird flying objects called UFOs, but what if they are not even flying. What if it is a 4 th dimensional object looking at us..... just as we look into a microscope and look at living cells....... what if something is looking at us?

So what youre telling me, is in the 4th dimension, i can see both sides of the coin simultaneously? And i could somehow say multiple words and have multiple conversations simultaneously as well, and there isnt much of a way to understand how thats done because everything here seems to be one or the other... But, best i can describe is saying apple while hearing orange somewhere in the peripheral of my mind.

Unfortunately this description is slightly flawed, although I can't think of a better way to explain it. But in flat land it would be impossible for flat people to see one another as they don't have anything to see! Being as flat as a shadow would make you invisible!
As well as that what are the flat people standing on?😂

I know this doesn't have anything to do with the video, but I would like to share these questions and this message with as many people as possible.

1. What do you think happens to someone after they die?
2. Do you think there is an afterlife?
3. If heaven exists, how do you get there?
4. Would you be good enough to get into heaven?

Here are a few questions to see if you are a good person:

1. How many lies have you told in your whole life?
2. Have you ever stolen?
3. Have you ever used God's name in vain?
4. Jesus said that "whoever looks at a woman to lust for her has already committed adultery with her in his heart" (Matthew 5:28). Have you ever looked with lust?
5. If you have broken any of these commandments, would you be innocent or guilty on Judgment Day?
6. Would you go to Heaven or Hell?

The Bible says that "all liars shall have their part in the lake which burns with fire and brimstone" (Revelation 21:8) and "Those who indulge in sexual sin, or who worship idols, or commit adultery, or are male prostitutes, or practice homosexuality, or are thieves, or greedy people, or drunkards, or are abusive, or cheat people — none of these will inherit the Kingdom of God" (1 Corinthians 6:9-10). So, if you are guilty of any of the ten commandments, then you are in trouble when Judgment Day comes! Do you know what God did for guilty sinners so that we wouldn't have to go to Hell?

2,000 years ago, God became a human being, Jesus of Nazareth, who suffered and died on the cross for our sins and rose from the dead on the third day, defeating death. The punishment that we deserve for breaking God's law, Jesus took in our place. He paid the fine that we could never pay so that God can legally set us free by forgiving our sins. He is just, by punishing evil through Jesus’ death on the cross, while being rich in mercy towards us.

What you have to do is repent, or confess and forsake your sins, and trust alone in Jesus Christ. Don't trust your own goodness, because, as Jesus said, “No one is good — except God alone” (Mark 10:18). Trust alone in the savior. The moment you do that, God will forgive every sin you have ever committed and grant you eternal life, and He will give you a new heart with new desires, so that you will love to do what is right. You will be born again. But you must repent and trust in Jesus.

When are you going to do that?

Here is a short Christian movie on this subject and depression: https://www.youtube.com/watch?v=fcqxzXMRGoc

There are no 'flat' 2D objects, 
and that includes really thin ink drawings,
because flat refers to height,
which is a three-dimensional concept/reality.
My guess:
Without height to connect them
thereby forming a plane,
length and width
are nothing more than coordinates
measured from a shared origin point.

The flat land and the apple. A perfect picture of us and the way God presented him self to us, in Jesus, the only way we could understand. Flesh and blood... And by the way. The fourth dimension, I call it ´the deep´ might be our consciousness or perhaps the world of quantum physics.

@Me Me If not even Richard Dawkins himself can deny that Jesus existed, then how could you? Then if he was devine or not thats another question. But we are many that clame he was, through different kinds of experiences. But you are free to think how you want. "This has been a story passed down to many generations"... Well, thats not completely true. When it comes to Jesus there is peopel that clames to be eyewhitnesses and their stories was written down. If you like to believe them or not it up to you. But if their stories was true then, its surtenly tru now. About " live in the now", is not even a argument.
Me Me

"the way God presented him self to us, in Jesus, the only way we could understand. Flesh and blood". Jesus? Flesh and blood? What? Were you there? Can you actually account for jesus' whereabouts? This has been a story passed down to many generations. How can you prove this by fact, now? Reminds me of the tall tales they always describe when the vikings killed the dragon. Come on, it's almost 2021, live in the now!

Flat land people would see an unfamiliar three dimensions in thier macro level landscape I think because although they don't have much height, they do have SOME height. Go macro and viola! Three dimensions in a two dimensional flat land.... This suggests to me that we can find another dimension floating around somewhere. Tiny strange dimensions abstracted within our own dimenson....

Right-left... up-down... front-back... and for the forth spacial dimension... larger-smaller. The 4rth spacial vector is scale. Or so it appears when graphing out all the vectors.
Consider the 4D cube "shadow" in 3D is a cube within a cube, with lines connected all corners. A 3d cube in 2d... is a hexagon. So the 4rth dimension runs along scale...which represents itself at right angles with all 3 known coordinate vectors.
You're welcome 😉 sometimes the most frustrating problems... have the simplest of solutions. Or if it's just Dunning Kruger on my part🤠... feel free to school me below👍

So its a set of infinite layers of infinite dimensions encasing a lower one in infinite angles. Hmm. Wonder what the smallest resolution you can actually see. Or even try to scope out how vast the universe truly is. Better just make things better on Earth first.

The fourth dimension is time. Sagan really missed it on this one.
Height, width and depth are nothing but a concept without time. He had it backwards. It's in TIME (the 4th dimension) we exist in essence as conscious experience.
Scientists are great, but don't ask them about the nature of reality itself. You need a philosopher for that.
