What is the longevity of the sun and the moon? The prehistoric universe? Our ancestors have been thinking about such questions thousands of years ago. Now that we have entered the age of technology, can we really answer them? With the development of the times, the problems we face have escalated. Because we have deepened our understanding of the universe, people have begun to ask whether there is a boundary in this universe? If there are boundaries, what is outside of the universe? What kind of space can accommodate the ever-expanding universe in which we live?
Universe
In fact, modern humans’ questions and thinking about the universe are not so much answered at the scientific level as they are answered at the level of consciousness or philosophy, because we humans recognize the universe. Knowledge is still very limited, and there is still not enough evidence to support the various hypotheses put forward by some scientists. So today the team leader will discuss with everyone a staged ultimate proposition of mankind on the universe, that is-"What is there outside the universe? What?"
Friends who like this topic, please give the captain a thumbs up, let's talk about it right away.
Outside of the universe?
Before starting, the team leader must first explain a more scientific theory, that is, the current cosmological model produced by humans based on scientific investigations does not actually interpret the true appearance of the universe very well, at best it is a total galaxy_ Model of span14span.
Because in the cosmological view of human science, this total galaxy includes countless like the we live in, the Milky Way, and extragalactic galaxies , of course, like black holes, , dark matter , and unobservable universes. The phenomenon is also in our view of the universe, and according to the universally recognized theory of the Big Bang, the universe exploded from a singularity in zero time and space about 13.7 billion years ago, and then expanded through continuous explosions. This led to the formation of the universe as it is now, but is this view really correct?
Universe
Why did the captain ask that? Because according to the famous Russian physicist: Friedman’s speculation,The average density of the total observable galaxies for human beings is relatively low. Compared with the entire space, it does not reach the critical rate of 10%. If my friends don’t understand, then let’s simply describe the collapse ability of this universe, which is higher than it is now. According to Dr. Friedman’s theory, we can almost see that the entire galaxy observed by humans will completely collapse in the relatively distant future. If human civilization still exists at that time, Not trying to escape from the destruction of a planet, but trying to escape from this universe.
In the description of the famous physicist Dr. Hawking, this total galaxy is like a deep well, and humans are frogs sitting at the bottom of the well, and can only see the small piece of sky at the mouth of the well every day, so time As it grows, humans will also start to wonder, what's outside this "sky"?
In fact, according to our traditional cognition, the concept of the universe may be different from that of Westerners. "Universe" is time and "Universe" is space. Therefore, the sum of the universe equals everything, because in human cognition In, everything is the concept of time plus space, and according to this concept, our ancient ancestors defined the universe as "infinity", and the universe is also understood as "being", then another space outside the universe, It's just "more", do you want to laugh when you see that there are many friends here? It’s not the captain who’s joking. The “and” actually refers to the space that contains another larger space in this universe. Of course, this huge space is relative to us humans. Perhaps in the eyes of creatures of another dimension, the universe is just a small space. The sphere is nothing.
In fact, people’s cognition of the universe nowadays is basically a concept given by human beings. Whether it is human civilization in ancient times or us now, it has given the universe an all-encompassing concept, but in fact we It can only be said that apart from our own existence and observable space-time, we don’t understand anything in other unknown spaces, so whether it is the concept of multidimensional universe or the concept of parallel universe, it is just one kind Conjectures, and such conjectures are actually just philosophical or physical conjectures, and there is no evidence to prove the authenticity of these conjectures.
book
But regardless of whether humans’ understanding of the universe is right or wrong,That space is real, waiting for humans to explore it. In Hawking's " A Brief History of Time", he compared the universe to a sphere with a finite volume, and also used our beliefs. An analogy with the known earth, because of a finite sphere, we can know its diameter and size, but a sphere has no boundary or beginning, so just like we will not fall out of the earth, we will not fall. To the outside of the universe, if human beings want to explore the universe and go in one direction and exceed the expansion speed of the universe, they will return to the origin. But is the fact really the same as Mr. Hawking's guess?
The universe is flat
The universe is flat. In fact, according to the latest research now, the universe is not only not a sphere, nor is it even curved, but very flat. In recent decades, we Human scientists use the deep space probe and the space telescope to continuously observe the universe at the largest scale, and then find that Mr. Hawking is wrong. There is actually nothing in the universe. Signs of bending.
When the time came in 2014, our scientists based on a scientific research of " baryon vibratory spectroscopic survey" and finally determined that the universe we can observe is very straight without any curved space.
When such a conclusion came out, all the big names in the scientific world were dumbfounded, including the Mr. Hawking we mentioned above. This conclusion that exceeds most people’s knowledge has sufficient scientific basis to prove Our universe is parallel, and scientists’ judgment is actually very simple. It is the reference of the microwave radiation pattern of the cosmic background and the measurement of cosmic rays. They found that not only cosmic rays, but also light emitted by distant galaxies, and The cosmic microwave background radiation does not produce a bend in space, but a straight course.
Because scientists have been observing for a long time,We have not observed any bending phenomena in the universe, so we have come to this conclusion, and the actual error of the instruments they use is less than 1%, so based on this result, we can basically use geometry to get the general idea of the universe. The shape is an extremely simple and huge "Euclidean space".
universe
Then we assume that the universe is a flat space, and close to infinity, this theory is correct, then the universe is an infinite space without boundaries. This result is unacceptable to us, and it is also disturbing, because finite is conceivable, infinite? Mankind does not have such imagination yet. This result directly overturns all the conjectures that mankind had about the universe in the past 100 years. According to the theory of the Big Bang, everything was nothing before the Big Bang, and then there was nothing at all. Is it infinite? No, not all of a sudden, but now it is infinite. How do we imagine that there is an infinite universe outside?
If we continue to deduct based on this theory, then the universe has no so-called center, and the expansion of space becomes expansion everywhere, instead of expanding in one direction, and from the microwave radiation map obtained from the scientific community, we can As you can see, all places in the universe are basically indistinguishable, and the region in which we humans are located is nothing special.
At this point, I am afraid that many people will question the captain. If the universe is infinite, then what else do I say about the universe? In fact, the team leader said that the universe recognized by humans is just a total galaxy in human cognition, but this total galaxy is not the whole universe, so the outside of the total galaxy is still this universe, and this universe is Infinite, matter is infinite, so there may be more than one total galaxy like ours, and this is the hottest parallel universe concept right now.
Planar Universe
But according to the team leader’s understanding,This parallel universe is actually a philosophical point of view. The truly objective stock should not have two you who are exactly the same, let alone a bunch of the same world. This point of view is just a manifestation of human arrogance. This kind of human thought is at work, and if the true parallel universe exists, the same world will not exist, because the appearance of our world is a miracle in itself, and it is an incredible miracle in this universe. Infinite such miracles can be born in this universe.
In fact, in the physical world, our universe is very simple, as simple as only more than 100 kinds of atoms, and these atoms are all composed of protons, neutrons, electrons, etc., and humans have studied quarks_ It's span14span level, but human beings are still far from penetrating the mystery of this universe, even if they have discovered the "God Particle". Today, I just discovered that dark matter still has dark energy.
And based on this research, we can get two conclusions, one is that we are the survivors of this flat and membrane-like "membrane universe", because in the vast universe, the place we see is silent, and Humans are like a race that has won the jackpot, struggling to survive in this universe. Because the probability of the birth of the earth and the birth of human beings is too low. In physics, this miracle is accompanied by 19 free parameters. Many people may not understand them. Then the captain will tell you that these 19 parameters, no matter what If there is a little change, this universe will not be suitable for survival, let alone civilization.
Big Bang
And the second conclusion is that the universe is a multi-universe, that is to say, this kind of "membrane universe" has more than one layer, but we are in this universe. Seeing this layer, we cannot see other "membrane universes", but in fact the infinity of the universe has long been filled by space, and this membrane universe is just like the quilt we spread on the bed. , You can directly cover the entire bed surface, of course, as many layers as possible on the net, so many people think that this theory,It is the closest to the truth, because this is more like a four-dimensional concept, and the membrane universe can be infinite, but it is this infinite or infinite that makes the proud imagination of mankind also difficult.
And the captain even more recognized the second conclusion, because the captain still hopes that if our universe is likely to collapse, humans can go somewhere else instead of passively annihilating with this space. It's the same concept as human beings have always been trying to "escape" from the earth.
Well, the world is very beautiful, thank you for having friends who are interested in this topic, welcome to discuss in the barrage or comment area, of course like and pay attention, next time you don’t get lost, we won’t see you or leave.
