If the universe is folded space, would the earth be flat when unfolded?

The translation is not very accurate, the Chinese reference is provided below
Flat earth theory of origin

The earth is flat that is an ancient world view, they think the earth is a huge plane, rather than a sphere, in the 5th century BC when the claim before Socrates who think so, until the 4th century BC, ancient Greek philosopher Plato said to round wrote his book, It was only when his pupil Aristotle (330 BC) provided empirical evidence that the earth was round that the idea of a round earth became accepted.

A map of the world as it was known at the time of Alexander

Whether the earth is round or flat, both may be right, after all, nothing in the world is absolute! Is evolution true? Not necessarily! Is the moon a natural satellite of the earth? Not necessarily! There you are! When science and technology were not so developed, mankind always had to pursue a higher realm! So science and technology developed! A scientist who wants to prove himself right, who wants to disprove a conclusion, works hard to find his answer.

A map of the world made by supporters of the Flat-earth theory

If you want to know whether the earth is round or flat, you have to start with space. What is space? What does space consist of?

It is not unreasonable to think that the earth is flat. We all live in a big space, and everything we see, touch and observe depends on this huge space. If the space is flat, we observe it as flat, and if the space is folded, we observe it as solid! And the space we exist in, and everything in it, is made of matter!

Q: What is matter?

A: It's like water and boats! They are not the same substance, but they coexist! All in the world at the same time! This is matter, and it's the kind of matter that we know, that we can see with our eyes.

Q: What is the matter you can't see?

A: Bacteria, viruses, air, particulate matter and so on.

Q: Can you see these things?

Answer: can't see!

Q: Do they exist?

A: Yes!

Q: Why is it so certain that these substances exist?

A: Because our technology has reached the point where we can observe the presence and shape of these things with all kinds of instruments.

So, just because we can't see it, and it hasn't been observed, doesn't mean the theory is wrong! Everything in the world is interlinked, a piece of paper is a plane, after folding is three-dimensional! So if humans are living on this folded paper, is the paper that humans are seeing and technology is detecting three-dimensional? If I unfold this piece of paper is this piece of paper another plane? If human beings have been living on this unfolded piece of paper are they living on a flat surface?

Maybe our space is a folded space! If this space were completely unfolded the universe would be flat! So there's no problem with the idea that the Earth is now observing a circle! There is no problem in saying that the earth is flat, but everyone's cognition is different and the standpoint of looking at things is different! Maybe everyone is right, maybe everyone is wrong! See, not necessarily true, so in the final conclusion, do not jump under the comment!

Who can guarantee that the world we live in is not controlled by the creator? Who can guarantee that everything grows and the motions of the celestial bodies are naturally formed? There are rules in this world, the law of the jungle is the rule, spring planting and autumn harvesting is the rule! How do heavenly bodies move without rules? Unproven, undiscovered, doesn't mean it's not there!

So, is the earth flat, or is the earth round, these two ideas can only be known after more advanced technology!

Ancient society is not developed in science and technology, or even no science and technology! Humans are too small to fly without transportation! It's so hard to measure the earth, to cross mountains, rivers and seas! Perhaps in ancient times, humans saw an endless river and thought it was the end of the world.

To sum up, if our space is folded space! Then parallel universes, wormholes, four dimensions would make sense too! We'll talk about parallel universes and wormholes and four-dimensional space theories later!
