Chapter 015: Dark Energy

What is antimatter? To put it simply, it is the anti-state of matter, from a philosophical point of view, it is to see things in two, the energy of this matter is extremely destructive, it is one of the most dangerous substances in the universe, and the monsters are not calm about this magical power.

Ignoring their agitation, Red Lotus continued: "And at this time, those tiny subatomic particles will really bond together to form atoms, and the first elements will be generated, the first one is hydrogen, which is the building block of many stars that we have seen. Remember when we break the Godhead and turn our divine power into gaseous form again? In these three minutes, two more elements are formed, and that is helium and lithium. ”

"Three minutes, this is the three minutes of creation, although it is short, but the changes in it can be infinite. ”

At this time, Elandi spoke: "I believe that through Guò's cosmic journey and various cosmic simulations, you all have a new understanding. But I want to tell you that in that time, you can't fully control the overall situation even if you are there, let alone just a simple simulation, let alone create a universe, a creation god, you just know now. ”

"Well, I know, we'll be able to keep simulating it so that we can slowly understand this principle. For Elandi's "commentary", the demons wanted to cry without tears.

At this time, Red Lotus didn't pay attention to Elandi's beating, but couldn't stop excitedly.

"At that time, the universe was like a dark soup, until the temperature dropped and the rampant electrons gradually formed hydrogen atoms, helium atoms, and lithium atoms. This time is long, about 380,000 years. The universe became lighter, and the first rays of light were born. Soar through the universe. On Earth, this ray of light that has been floating for 14 billion years has only been discovered. ”

"After this stage, the universe has begun to take shape, there is already a clear outline, the areas without matter will become vacuums, and the places with large matter will evolve into galaxies, and the gas clouds formed by hydrogen and helium at that time will float everywhere until 200 million years later, when the first stars are born. And this is a huge and extremely gorgeous space fireworks feast, and burning has become the main theme. ”

biu!biu!biu!

"It's so beautiful! Husband, let's not simulate like this in the future, let's create our own universe to watch fireworks, how about it?"

Honglian's hands shook as she kept flying, and then she said with some embarrassment: "I'll see this with my own eyes, but this one is a little too far away." We'll talk about it later. If I could, how could I have rejected you?"

The grand fireworks that brought the universe from the Dark Ages to the Glorious Age are one of the rare sights, and it's exciting just to think about.

"Ahem. This has a beginning and an end, and the universe is also going to be ruined, but it takes a long time. And as we said before, the Big Bang is hypothetical. Now let's see, if the Big Bang is the beginning. Could the end end be the opposite, the Great Collapse? The universe can be said to have an infinite number of components, and its size is not divided into the so-called inside and outside, just like the Big Bang, if the Great Bang is completed, will such a huge energy transformation trigger the Big Bang again? The two sides will never stop exploding, collapsing, and creating the world. ”

"It's up to us to comprehend this, so let's take a look at another powerful substance, which is rumored to be able to destroy the existence of the universe, what is dark energy. Come on, the model is up. ”

Speaking of this, Honglian turned an area in front of her into darkness, put a miniature version of the galaxy, and then put an eye on the opposite side: "You see, suppose there is only one galaxy in the universe, and this eye is our eyes or ordinary people's eyesight, observing or something. As we just know, it may take millions or hundreds of millions of years for this eye to see, but how do we know for sure that the galaxy is there? ”

At this time, Red Lotus put a blue circular object in the part connected by a dotted line between the miniature version of the galaxy and the eye: "This is the model of dark matter, according to the general theory of relativity, we can know that mass can produce a gravitational field, it can bend light, and if the light that enters our eyes is bent, then how can we determine the position of the galaxy? Alas, by the way, it may be above this galaxy, and similarly, a galaxy will appear below the galaxy." ”

"And what is the model of general relativity? Yes, three-dimensional space, so light can also enter a cone-shaped way and bend into the eye, and the eye will see a circle, which is the Einstein ring. And it's so easy to see this, which of you has a wine glass?"

After searching for a while, Sophia took out a red wine glass, and after Red Lotus took it, she immediately removed the upper part of it, leaving only a base, and then he took out another piece of parchment, and drew a grid and a dot in the middle on it, which was used as a model of the galaxy.

"Come, you see, this is the gravitational lensing, through it, you can see the Einstein rings, changing different positions, you can see how the lines are twisted, this is a very accurate model, this is the same galaxy that we see with the naked eye, but it is magnified many times. It is because of this series of numbers that the existence of dark matter has been determined. In fact, the matter that can be seen by ordinary people accounts for about a few percent of the universe, about 20 percent is dark matter, and the rest is all dark energy. ”

Putting away the model, Honglian pulled her hands and immediately explained the dark energy: "At the beginning, some ancient astronomers explained that the universe is composed of four basic elements: earth, water, fire, and air, that is, the basic properties of matter: cold, hot, dry, and wet, until many years later, another person put forward the fifth element, and he believed that the universe is composed of the earth composed of these four basic elements, and the stars and planets composed of the fifth element, and he named this fifth element as the ether. ”

"Let's start with the Earth, which we know from itself that it is a planet, and it is part of the solar system. In a huge wheel of stars and gas, the Milky Way as we see it. The Milky Way is gravitationally bound to the local group of galaxies, which in turn is gravitationally bound to a cluster of galaxies of thousands of galaxies, which in turn is gravitationally bound to a supercluster of tens of thousands of galaxies. This supercluster of galaxies with a spatial scale of 100 million light-years forms a new pattern with galaxy filaments and vast voids. ”

"Ironically, time moves forward, and wisdom doesn't mean it moves forward. Years later, those juniors began to study the fifth element that their predecessors called it, and after they introduced it, they began to study it again. It has to be said that the great scientist Albert Einstein has appeared again, he has been studying gravity, and even wants to unify an equation to explain everything in the universe. When he first started researching, he kept thinking, why didn't this gravitational force collapse the universe? There must be a repulsive force that opposes gravity, which he calls the cosmological constant, and is represented by the symbol "Λ". ”

"Of course, with the advent of Hubble's law that we talked about before, this made Einstein affirm this scientific and technological achievement at the same time, but also called this cosmological constant the biggest mistake in his life, because the universe is constantly moving, not quiet, of course, and later ironically, people picked this up again......"

"Later, people developed to the age where they could simulate the universe, and they compared this dark energy to vacuum energy, and there are theories that the fifth element will change over time, and there is also a theory that dark matter and dark energy are combined to form a dark fluid, and there is also a theory that the dark energy will change from a thrust to a pull at some point. At that time, everything in the universe will shrink to the size of a proton, or it will just explode. ”

"Well, which power made us, and if we had the chance, wouldn't we all die?"

For this question, Honglian was a little stunned, yes, what if the power of the universe where the Sky Continent is located is unhappy one day and crushes the entire universe?

"Don't worry, as I said before, even the creator of the world cannot fully control that infinite change, and as long as he becomes a god, this kind of problem will not occur, and the creator will not be so ruthless, of course, this may not be said. ”

For Elandi's sudden "comfort", they felt cold sweat again, it is better to cultivate to the highest level as soon as possible, and there will be a day when they go crazy consciously, rather than handing over their fate to unknown people, it is better to control it themselves.

"Ahem, we don't have to worry, don't worry. If the assumption that string theory exists is true, then we are still living on a cosmic membrane in a higher dimension, and those powerful beings may be pinched to death by high-latitude creatures. Who told you to say that?!Didn't we make an appointment with this for the protagonist of the second part of the Fashen? Do you want to get a bento?"

"Wow, husband, what's wrong with you? This author-kun is here again!"

"He, he's afraid that I'll talk too much, and if we're done talking, what will the protagonist of the second part say?

"Red Lotus, don't give me this set! I'm also a demon, you pay attention to yourself, and then leak the string theory, be careful that I let you all get the lunch!"

"Ahem, let's move on to dark energy, no, let's talk about galaxies. (To be continued......)
