• In the last few days this question has preoccupied me a lot, which is why I will now share my thoughts with you. As a little warning, it's a pretty exhausting subject, so your head could be smoking quickly (lol).

But what is infinity anyway?

Infinity describes the abolition of finiteness and theoretically describes an object (e.g. sphere) or an infinite process without an end. In mathematics, infinity is very easy to imagine. If you take a function with the equation y = f (x) = X, it would increase as a straight line, monotonically, infinitely long. In addition, the number Pi (π) is infinite. It starts with 3.1459 ... and at some point it only continues with 1 and 0.

A better example of what emphasizes the crazy about infinity (from "100SekundenPhysik"):

Imagine a monkey who owns a typewriter with only letters. The monkey taps around indiscriminately on this - infinitely long, with the prerequisite that it also lives indefinitely. There are 52 + 1 ways to type a letter, if you consider upper and lower case and the space bar, 52x52 + 1 for two letters, etc. After a while the monkey manages to type a word. At some point he even completes his first sentence, even copying a poem. At some point, probably after many years or decades, he managed to copy Johann Wolfgang von Goethe's "Faust I" by chance. But now it's getting crazy: after many thousands, even millions, maybe billions of years, he has copied all the books in the Alexandria library, the largest library in the world with over 170 million works, 1: 1. In other words, in infinity he even begins to write completely new, but coherent, logical books at some point.

But what about my question now? Well, we have already clarified that in mathematics, infinity is theoretically easy to prove.

But if you refer to the universe, to the basic physical laws, so to speak, the whole thing looks very different. Let's first refer to the earth: Imagine the earth would be infinitely large, theoretically, so leave the solar system exactly as it is, only that the earth is infinitely large. If the earth were to be preserved indefinitely, the following would happen:

1. There would be an infinite number of people and thus an infinite number of babies, children, adults, pensioners, dying people on earth, which means that there are infinitely dead and infinitely living, which is a paradox (= contradiction).

2. We would have an infinite number of resources, regardless of whether it was wood, coal, iron, diamonds, etc., which means that there must be an infinite amount of money, since the price of goods drops drastically and there are thus also an infinite number of rich and poor, although all are infinite have a lot of money there. Another point is taxes. The state would then demand an infinite amount of tax money (∞ x 50% = ∞), which is once again a paradox.

3. The chemical composition changes. (I thought we were following the basic laws of physics ?! Um, I'll explain that anyway.) In our earth's atmosphere there is about 21% oxygen, almost 78% nitrogen and 1% other gases. If the earth were theoretically infinitely large, these percentages would also theoretically have to increase. The ratio would be right, but all percentages have risen to infinity. EDIT !! Not the percent would change, but the number of atoms. These would rise to infinity.

Using this example, I can also relate that to our universe. If our universe were infinitely large, there would be our earth infinitely times in a 1: 1 replication, if not even our solar system or the whole galaxy or directly an infinite number of 1.1 replications of our universe, which then makes no sense, why I opened this topic. The infinity of our universe makes no logical sense, at least three-dimensionally. One would have to imagine a tesseract, a four-dimensional space * in which the universe could appear twice, in repetitive form. In fact, one does not need infinite dimensions for this, since in this tesseract the universe is in an infinite loop and is therefore theoretically infinitely often present.

* You really only need to consider the space here. From a theoretical point of view, time is namely the fourth dimension, which includes the duration of the expansion of an object (in our case, age, from infant to old man). So I would have to speak of a five-dimensional space-time. (4 space dimensions + 1 time dimension)

What does that mean?

If our universe were to be infinite, it would have to be in a five-dimensional space-time continuum, which has not yet been proven, but also not yet disproved.

This is my contribution to the possible or impossible infinity of the universe. I hope your head doesn't smoke too much or I'll be sorry and recommend a nice shower for the headache. What is your opinion on infinity? Crazy garbage or logical answer to a lot of questions? Write it under here!

• A very interesting thought construct that you have there.

As luck would have it, I recently read something about it that I quickly picked out:

Here and here

Would like to write more about it, but my brain and I are easily exhausted today

But find your contributions regarding theories and explanations about the universe or general astornomy / astrology interesting again and again.

Keep it up

• At this point a question: Even if your thought experiment is correct, what if there is a 5th dimension? Would that really "prove" infinity?

After all, in mathematics one can "invent" an infinite number of dimensions. The best example is the imaginary dimension (C), where one can calculate from the root of -1, which cannot be calculated in any other dimension.

In my opinion, a lot of this is just beyond our understanding. Sure, that's an answer like "because tree" or "42". The universe is a reproductive structure. Many of our "stars" are partially emerging universes or have burned out. E.g. our solar system has an expiration date. At some point the sun will implode and collapse, the resulting debris will become an asteroid and may or may not hit a second asteroid on its journey, and a big bang may or may not occur.

The next question would be numbers, letters or everything together in a book are human inventions to master the "chaos" and to give everything a conceivable shape and a name.

Why chaos?

Def. According to Wiki: "That chaos [ˈKaːɔs] (from ancient Greek χάος cháos) is a state of complete disorder or confusion (Confusion) and thus the opposite term to cosmos, the Greek term for the (World) order or the universe. "

Let's assume that people have other names for the numbers, but that does not include the infinite sequence of numbers between the numbers themselves. How do you solve the problem by splitting everything into precisely defined quantities, which you give a name, etc. Chaos, somehow defining what you have in front of you and making it understandable to others so that you can communicate.

E.g. the numbers 1-9, i.e. N (natural numbers = all positive numbers without commas). However, we define Z (whole numbers = positive and negative without commas), Q (rational = Z + decimal numbers) etc.

The whole process is also known as a fractal. (Strongly articulated)

This is the only way to somehow make the incomprehensible again understandable. And why do I say that? Because I am of the opinion that infinity is defined by the fact that it goes beyond our imagination and that it is entirely possible that the universe is infinite. But we will never really understand both in our technology, as well as in our understanding, because it is simply incomprehensible from the outset as it has been defined.

• To answer your first question: No, it wouldn't be. The universe would have to be five-dimensional for infinity, but five-dimensionality is not the same as infinity. Why? Quite simply because the fifth dimension could also express a completely different state. Perhaps another mathematical spatiality that is approaching infinity, but not yet fully embracing it.

By the way, our stars are not universes or emerging universes. Stars are just the gravitational center of a normal solar system. According to a theory that I also explained in my specialist work on black holes, there is certainly a new universe "behind" the zone of singularity that has similar or even the same physical laws as ours.

Our sun does have an expiration date, but not the whole system directly. Our sun will have used up the entire hydrogen supply in about 4 billion years and will therefore only have helium in its core. This leads to the expansion of the star. The star can expand up to a hundred times its normal size, which means that almost all inner planets (Mercury, Venus, Earth and possibly Mars) are swallowed up by the sun. The star therefore begins to burn its shell and the helium is now converted into carbon.

But if the helium should run out at some point, the temperature pressure lets it shake and the balance between gravity and temperature pressure starts to shake and the star finally explodes in a supernova. In theory, it also implodes, because gravity works from the outside in and the layers are literally pressed onto the core, which is now just a small white dwarf.

The next point is very interesting and by no means wrong. Man tries to make life as easy as possible in all areas and he achieves this with this strong structure. Of course, infinity also goes beyond our imagination, which is why this topic is so brain-eating and makes the head smoke.

I hope I was able to help you out on a few points!

• When I sent a friend of mine today a picture in which you can see the solar system in comparison to the largest black hole found so far, she asked me whether the earth could be infinitely small in infinity. I answered yes to that question and then I explained it a bit to her.

When I broached the subject of the tesseract, a confused thought occurred to me. If there is an infinite universe in the tesseract, there are infinitely many 1: 1 replications of the universe, which means that an infinite universe corresponds to a multiverse, which is impossible in classical physics. It is impossible because otherwise 1 = 2 or 1 = 3, etc.

But there is also quantum physics, which is based on fundamental physics, but has its own mathematical formalism, which then opens other doors.

Unfortunately, I don't know enough about quantum physics, but at some point I'll find out more.

• Once again I came across a small insight that can bring this discussion to a standstill very quickly.

For those who don't already know: The universe is expanding and it will expand ever faster - one suspects. If one assumes that the expansion of the universe is accelerated by the mysterious dark energy, theoretically it has to reach an infinite value at some point. But since we know that infinity does not capture a specific number, but rather describes a state of a body or a surface, it is again impossible to achieve an infinite acceleration.

What I mean by that: If the universe were actually infinite, the expansion should have had an infinite acceleration from the beginning. But our universe could not allow such a strong acceleration due to the lack of energy.

This means that our universe is by no means infinite, at least in my theory listed here. Maybe at some point I will come to another realization; but so far it doesn't look like it.
