universe
What do you think of this trip to Earth's oviparous galaxies 1,400 light-years away?
A group of scientific scientists have discussed...
Let's take a look at the universe before making a decision...
The International Space Agency uses video projections to explain the universe... A screen of light appeared
The universe is the general term for all things, the unity of time and space. The universe is a material world, which exists objectively and does not depend on human will, and is in constant motion and development, with no beginning and no end in time, and no boundary and no end in space. The universe is diverse and unified; diversity in the diversity of material manifestations; Unity lies in its materiality. The universe is a unity of space, time, matter, and energy...
In every place in the universe, the energy is different, there is positive energy, there is dark energy, and there is no energy.
The Big Bang theory is currently more popular. According to the Big Bang theory, the history of the universe can be represented as a closed surface with an open right end.
Markla said: Look at the picture here. At the center of the left end is the explosive singularity, which extends 13.7 billion light-years to the right. From left to right: singularity, 400,000 years of initial expansion, nearly 400 million years of dark periods, emergence of stars, galaxies and planetary developments, and accelerated expansion of dark matter and dark energy. That is, the universe is expanding...
The shape of the universe is still unknown
Scientists are imagining it boldly. Some people say that the universe is actually a small cell of a creature similar to a human being, while others say that the universe is a program or a small original made by a computer creature with higher intelligence than humans. There are also arguments that the universe is actually an electron, that the universe is a much smaller thing than an electron, that the universe does not exist at all, or that the universe is intangible. There are also speculations that our universe lives in a large space called "hyperspace". In hyperspace, there are many universes, and the energy of hyperspace is conserved and very huge. Whenever the energy of one universe rises, the energy of its neighboring universes falls.
Using entire galaxies as lenses to see other galaxies, researchers have recently used a precise method to measure the size and age of the universe, and how rapidly it expands. This measurement confirms the usefulness of the "Hubble constant", which indicates the size of the universe and confirms that the universe is about 13.75 billion years old.
Scientists continue to look at cosmic projections... The universe may be superfluid, suggesting that we may be living "underwater", and new research suggests that space-time may be a fluid in nature, which can be thought of as a superfluid, which is different from other matter, but can provide a new medium for photons, just like sound travels through the air.
Some researchers believe that if this medium "carries" the movement of photons exists, then its viscosity should be zero, which will open up a new theory for us to explain this strange phenomenon through quantum gravity.
There has been no definite answer to the question of what space is and why it is "empty", but space carries the movement of photons, electromagnetic waves, and all other matter. In response, scientists believe that space-time itself may be a superfluid, and this explanation can be used to decipher the motion of some matter, and if this theory is correct, then we may revisit the Standard Model of physics. Scientists at the University of Munich believe that space-time is considered to be a superfluid theory for superfluid vacuum theory, and its development is based on the previous scientists' research on space-time, if you want to prove that the superfluid theory is correct, then you must first solve the problem of viscosity
Okay, these are some of the questions that can't be verified, so what do you think?
Researchers say: The universe should have no beginning and no end, and there is no beginning and no end.
Well, your point of view was speculated decades ago, and it's possible, so what do you think of the rest?
Someone asked rhetorically, "Just now the projection also said that the universe is superfluid, if the universe is a superfluid, do we live in a supergiant's body?" Each planet is a certain cell of this supergiant, and the interaction of gravity ensures the existence of this supergiant, and the superfluidity is the cell fluid? ”
Well, this possibility cannot be ruled out, but these need to be explored by us scientists from generation to generation
It's so mysterious. There is so much we need to know, and hopefully we will learn more about the mysteries of the universe in our lifetime. Therefore, countries should join forces, concentrate on research and development, stop always clinging to immediate interests, and jointly explore the mysteries of science
Someone retorted: "If the universe is in a so-called superfluid state, it proves that the ether exists, and it also proves that the theory of relativity is wrong, how can this be explained?" ”
Then I ask you why Alexander's theorem was overturned? Because as long as you can prove something unexplainable, then you are the next Newton! If you can overturn something and prove it, you can overturn gravity too!
Superflow? Isn't that the ether? Didn't Aristotle come up with it, but he came up with it out of thin air?
Without the support of observational data, it is like saying that the current string theory, which cannot be verified, is metaphysics! Otherwise, there wouldn't be so many ideas.
If space is a superfluid, then does it blend with the atmosphere? If it is not blended, where is the dividing line? Does superfluidic have mass? If there is mass, where is the gravitational force it produces? I think the universe is a huge "black hole".
Let's take a look at the projection of a black hole
A black hole is a singularity with infinite density, infinite curvature of space-time, infinitely small volume, and infinite heat in the center, and a part of the surrounding empty celestial region, which is not visible within the scope of this celestial region. According to Albert Einstein's theory of relativity, when a dying star collapses, it will gather into a point where it will become a black hole, swallowing all light and any matter in the adjacent cosmic region.
The creation of a black hole is similar to that of a neutron star: when a star is preparing to perish, its core rapidly shrinks, collapses, and explodes under the force of its own gravity. When all the matter in the core turns into neutrons, the contraction process immediately stops, and it is compressed into a dense star, which also compresses the space and time inside. But in the case of black holes, the mass of the star's core is so large that the contraction process goes on endlessly, and even the repulsion between neutrons cannot be stopped. The neutrons themselves are crushed into powder by the attraction of the squeezing gravity itself, leaving behind a material that is unimaginably dense. The gravitational pull due to the high quality is such that any object that comes close to it will be sucked into it.
Usually, stars initially contain only hydrogen, and the hydrogen nuclei inside the star collide with each other and fuse. Due to the massive mass of stars, the energy produced by fusion competes with the gravitational pull of the stars to maintain the stability of the star structure. As a result of the fusion of hydrogen nuclei, a new element, helium, is produced, and then the helium atoms are also involved in fusion, changing their structure to form lithium. By analogy, according to the order of the periodic table, beryllium, boron, carbon, nitrogen, etc., will be formed in turn, until iron is formed, and the star will collapse. This is due to the fact that iron is quite stable, and the energy released when participating in fusion is less than the required energy, so the fusion stops, and iron exists inside the star, causing the star to not have enough energy to compete with the gravitational pull of the massive star, which causes the star to collapse and eventually form a black hole. It is called "black" because it generates a gravitational pull that makes it impossible for the light around it to escape. Like neutron stars, black holes evolve from stars that are tens or even hundreds of times more massive than the Sun.
When a star ages, its thermonuclear reaction has depleted the center of fuel, and the energy generated by the center is running out. In this way, it no longer has enough strength to carry the enormous weight of the shell. So under the weight of the shell, the core begins to collapse, and matter will march inexorably towards the central point, until finally a star with a near-infinitesimal volume and almost infinite density will be formed. And when its radius shrinks to a certain point (it must be smaller than the Schwarzschild radius), the mass-induced distortion of space-time makes it impossible for even light to shoot outward – and the "black hole" is born.
Black holes stretch, tear and devour stars
Black holes are usually discovered because they collect the surrounding gas to produce radiation, a process known as accretion. The efficiency of radiant heat energy from high-temperature gases can seriously affect the geometrical and kinetic properties of accretion flows. Thin disks with higher radiation efficiency and thick disks with lower radiation efficiency have been observed. As accretion gases approach the central black hole, the radiation they produce rotates the black hole and acts as a flow of the central extended material system. Accretion is one of the most prevalent processes in astrophysics, and it is precisely because of accretion that many common structures around us are formed. In the early days of the universe, galaxies were formed when gas flowed towards the center of the gravitational potential well created by dark matter. Even today, stars are formed by gas clouds that collapse and fragment under their own gravitational pull, and then accretion of surrounding gas. Planets, including the Earth, are also formed around newly formed stars through the accumulation of gas and rocks. When the central object is a black hole, accretion takes on its most spectacular side. In addition to accreting matter, black holes also radiate particles outward through the process of Hawking evaporation.
Since the density of the black hole is extremely large, according to the formula we can know the density = mass/volume, in order to make the black hole infinite density and the mass of the black hole unchanged, then it means that the volume of the black hole should be infinitely small, so that it can become a black hole. A black hole is a death star formed after the "extinction" of some stars, and it is extremely massive and extremely small. According to Hawking's theory, in quantum physics, there is a phenomenon called the "tunnel effect", that is, although the field strength distribution of a particle is as strong as possible in the place with low energy, even in the place where the energy is quite high, the field strength will still be distributed.
Each black hole has a certain temperature, and the temperature is inversely proportional to the mass of the black hole. In other words, the temperature of the great black hole is low, and the evaporation is weak; The temperature of the small black hole is high and the evaporation is also intense, similar to a violent explosion. A black hole equivalent to the mass of the sun takes about 1x10^66 years to evaporate; A black hole the mass of an asteroid evaporates in 1x10^-21 seconds.
Well, the above is the explanation of the black hole, and the black hole tunnel we built with quantitative ions is this kind of teleportation device that exceeds the speed of light, which selects the measured force space from x matter, and uses the sunspot force to generate infinite flow of power to achieve space operation...
So, Doctor, will we be able to reach the Earth's twin galaxy?
This can't be guessed, because last time we used an artificial intelligence robot to carry a spaceship, and in the end we couldn't move for some reason, and we could only project a silver galaxy 1400 light-years away, and we couldn't know whether we reached the Earth's twin galaxy
