How did the universe originate? What is the best theory about the origin of the universe right now?

The problem is complicated if everything is deduced according to the logic of cause and effect.

Just like a primary school student learning math, you have to memorize the 99 multiplication table, you don't need to know why, it's this law, and you are right to use this law to do problems.

If it is said that the universe is large, where does the high-density body come from, and where does the material that produces the high-density body come from.

Based on the current observations, it is based on the following points:

1) The upper lifetime of stars in the universe.

2) Helium abundance in the universe.

3) Microwave background radiation of 3k.

4) The amount of substances with a long half-life.

These articles can only be explained reasonably by using large **, and the joint estimation time is more than 13 billion years.

There is also the universe **, this kind of problem is beyond the scope of science. It's like asking what you did before midnight today, and it doesn't make sense to go beyond today's concept in the question.

It is true that there is a beginning and an end, but the singularity of ** is the complete starting point of time and space for our current universe, and the outside and the past can only be imagined as complete nothingness.

This is a question that our current science cannot answer at all, and everything can only be inferred based on our knowledge of the world. And we usually say what is outside an object always because we can look at it from a higher macro perspective, but for the world that contains us, we are more helpless, we can only use imagination to construct what we do not understand, so we can't say that there will be a definite answer, and everyone can only choose a statement that they think is accurate. Science will be logical, but logical is not necessarily scientific, so when science can't answer the question, choose according to your own feelings.

The so-called big theory of the universe is just speculation, and there is no verification, and I believe that human beings will never be able to explain this problem!

Wouldn't it be nice to buy a time machine and go back in time?

First, the big ** theory.

The grand ** theory holds that the universe originated from a single dimensionless point, that is, a singularity that is scaleless in space and time but contains all the matter in the universe. At least 12,015 billion years ago, the universe and space itself were formed from this point**.

Second, the steady-state theory (has been denied, but if you want it, you can post it.) The homeostatic theory holds that the universe remains the same at all times, on average, for centuries, and many scientists believe that the universe has changed little except for a few subtle parts. The universe does not need a beginning or an end.

Even after discovering that the universe was expanding, this idea was not abandoned. This theory was put forward in the late 40's and believed that matter was being created at an appropriate rate just enough to maintain the density of matter in the universe. The universe remains the same at all times, on average.

One of the advantages of homeostasis theory is its clarity. It predicts with great certainty what the universe should look like. Because of this, it is easily challenged or refuted by observational facts.

When cosmic background radiation was discovered, this theory was largely refuted.

In addition to the well-known theory of the great ** origin. Also newer is the "steady-state theory.""and "The Ultimate Theoretical Conjecture of Dimensional Shifts". Homeostasis theory mentions:

The universe has always been like this, and it doesn't need a beginning or an end. The theory is that new matter is created in the expanding space between the galaxies that exist. The latter refers to the fact that our existing four-dimensional universe is transformed from other dimensions, and that various different dimensions are transformed into each other.

The shift from zero-dimensional (i.e., what we say is that no time and space equals "non-existence") to other dimensions explains the concept that our existing four-dimensional universe is "created out of nothing", and thus provides an answer to how the universe existed before it was born. It also forms a set of basic concepts that can be self-circulating, without any logical loopholes.

There are two theories of the origin of the universe, the "Great ** Theory" theory and the "Black Hole Theory".

The universe is vast and infinite, boundless, and has no beginning or end. At present, the universe as human cognition is limited to the theory of the formation of the "universe is great", and in order to completely solve the mystery of the universe, people need to continue to explore, research and discover in the future.

1. The universe is a general term for the vast space and the various celestial bodies and diffuse matter that exist in it. The origin of the universe is an extremely complex issue. Modern astronomical observations prove that it is in constant motion and development.

For thousands of years, scientists have been searching for when and how the universe came to be. Many scientists believe that the universe was formed by a large ** that occurred about 14 billion years ago.

2. The mainstream view in modern cosmology is that the origin of the universe originated from a large state, which evolved from a state of extremely dense and extremely high temperature in the past, and reached a state through continuous expansion, which is called the grand theory of the universe or the theory of singularity.

The universe is mysterious, full of unknowns, worthy of our continuous exploration, the universe is boundless, the scope is very wide, including space, time, matter, etc., quite complex, so what is the origin of the universe? What was before the origin of the universe? Below byKnowledge of horoscopesLet's reveal it for everyone!

What is the origin of the universe.

In the 20th century, two influential "models of the universe" emerged. One is the steady-state theory, and the other is the big ** theory. And in the late 20s of the 20th century, Edwin Hubble discovered the phenomenon of redshift, indicating that the universe is expanding.

In the mid-60s of the 20th century, Arnault Penzias and Robert Wilson discovered "cosmic microwave background radiation". These two discoveries give strong support to the big ** theory.

Today, many scientists believe that the universe was formed by a big ** that occurred about 13.7 billion years ago. The matter and energy in the universe are gathered together, and condensed into a very small volume, the temperature is extremely high, the density is extremely high, and the huge pressure is generated in an instant, and then a large ** occurs, and the reaction principle of the big ** is called quantum physics by physicists. The big ** caused the matter to be scattered, the cosmic space continued to expand, and the temperature also dropped accordingly, and then appeared in all galaxies, stars, planets and even life in the universe one after another.

What was the universe before the origin of the universe.

What was the universe like before it was born? On this question, Stephen Hawking gave his answer.

As scientists now know, the universe continues to expand after the big **. In the same way, when you look in the opposite direction, the universe is shrinking. Hawking said that if you replay it far enough away (about 13.8 billion years), the entire universe would shrink to the size of one atom.

This atomium of all things is called the singularity, and in this tiny, extremely dense particle of heat and energy, the laws of physics and time as we know them cease to function.

In other words, as we understand it, time actually didn't exist until the universe began to expand. Conversely, as the universe becomes smaller and smaller, the "arrow of time" shrinks endlessly, never reaching a clear starting point.

According to Hawking's interpretation, time is bent before the "big **": "It always approaches something, but it doesn't become something." Essentially, the 'big** never produced anything. ’”

Stephen Hawking writes in his theory of borderlessness: "The events before the big ** are not defined at all, because we cannot measure what happened before the big **." Since there are no observations of the events before the big **, we might as well remove them from the theory and say that the time began with the big **. ”

Big**Big**: The prelude to the universe was unveiled About 15 billion years ago, an earth-shattering big ** occurred - the universe was born! At that time, the universe was a very dense fireball with a temperature of several trillion degrees.

There are many particles in the pulsating chain, which collide with each other. These particles are the basic units that make up all the elements in the universe.

After the big **, when the matter that makes up the galaxy in the universe appears large, the proton is already there, and less than a minute after the big **, the helium nucleon is produced. After about 100,000 years, the temperature of the universe gradually decreased, and the proton and helium nucleons combined with electrons to become hydrogen atoms and helium atoms, which are the main elements that make up galaxies.

Take our galaxy as an example, look at the formation of the universe scattered in the universe of matter is sparse and dense, the dense area of gravity is larger, will suck the nearby gas, more and more, become a large gas mass, and slowly shrink, this is the primordial galaxy cloud.

Our Milky Way is just one of them, the Milky Way in the Milky Way is densely distributed in the Milky Way, the dense areas will shrink and condense, and finally shine brightly, and the stars will be born, and the Sun is our Milky Way2'One of 00 billion stars.

Since the 17th century, the British scientist Isaac Newton discovered universal gravitational endurance, that is, all objects in the universe including stars, the sun, the moon, planets and other objects have mutual attraction, the greater the mass of the object, the greater the attraction, the distance between the objects increases, the gravitational attraction will weaken, all galaxies in the universe, the formation of planets, are controlled by gravitational force, interstellar matter gathers to form galaxies, planets.
