0 9 uses one of the numbers to represent the center of the universe, which number do you think is mo

I think 0 is the most suitable.

Everything in the universe originates from zero and returns to zero, and the universe has been going through the process of coming into existence and from being to nothing. The theory of the universe is that the universe originated from a big one, which produced time, space, matter and energy, and then gradually expanded, and after a long period of development and evolution, it became what it is today. Before the big **, the universe was a singularity with no size, no shape, and infinite density, which contained everything at that time.

Interestingly, because it is formless and volumeless, it does not exist in a sense. The big ** theory also believes that when we expand the universe to a certain extent every day, it will begin to collapse and become smaller, and the final result of the collapse is that the universe will return to the state before the big ** - a singularity. At that time, our universe will cease to exist, and the universe will begin to enter the next cycle over and over again, producing completely different cosmic ......The universe was formed and destroyed by a singularity, so the center of the universe in both periods was a singularity.

As for the center of the universe in other periods, I think it should also be close to the state of the singularity - "nothing", ......

8 because it has two rings, one for light matter and one for dark matter.

1.Because I think the universe should be the simplest.

0, I don't know why.

0 The cosmological constant has to be served.

We live in a world full of numbers, and everyone also has their own preferred numbers. For example, some mathematicians are obsessed with prime numbers, , Euler numbers, while others are obsessed with fine structure constants and cosmological constants. In this article, we will see some numbers that are crucial to our understanding of this universe.

Note: 1The "Hubble-Lemaître Law" used to be known as "Hubble's Law", and in October 2018, the International Astronomical Union (IAU) decided to change it to its current name in honor of the astronomer George Lemaître, who discovered that the universe was expanding before Hubble.

2.Over the past few years, scientists have realized that the Hubble constant, measured with different measurements, is not consistent, which is one of the biggest contradictions in cosmology today. The text refers to the latest value given on the cosmic microwave background, h0

km/s/mpc；And another equally very accurate method gives the Hubble constant to be about h0

±km/s/mpc。In the future, it may be possible to solve this contradiction when scientists detect the gravitational waves emitted by the merger of more and more neutron stars.

3.Stars that exceed the mass of the Sun will collapse into neutron stars, but neutron stars also have an upper limit on mass, which is known as the TOV limit. Beyond this limit, the neutron star will collapse into a black hole due to its own gravitational pull.

4.Boltzmann's constant kb

The value of is j k. On Boltzmann's tombstone, the famous formula is inscribed: s=kb

logw。5.Density parameter 0

It is determined by the true density ( ) and the critical density ( c. ) in the universe

Definition: 0 c

where is the total mass in the universe energy density, in other words, it is the sum of the different components of the universe, including ordinary matter and dark matter, as well as dark energy.

One, there is a gravitational constant.

The gravitational force between the sun and the planets is directly proportional to the product of their masses and inversely proportional to the square of their distance. --Newton's law of universal gravitation.

f=gmm r1, g is the gravitational constant, g=, because the value of the gravitational constant is very small, the gravitational force between objects of general mass is very small.

wormhole) two, the speed of light.

According to Einstein's special theory of relativity, the speed of light is constant, and the speed of light is about 300,000 kilometers per second in a vacuum.

There is an upper limit to the speed at which information (the speed of light) can be transmitted, so that what happens in different regions of the universe will not reach the Earth in an instant, or any planet where life exists, and living things will not be "drowned" by the massive amount of information, and evolution will be possible.

The magnetic levitation phenomenon produced by superconductors at ultra-low temperatures. ）

Three, absolute zero.

Absolute Zero - The lowest thermodynamic temperature: Absolute zero is the lower limit of the theoretical limit, and its thermodynamic temperature scale is written as k, which is equal to minus degrees Celsius (.

Heat starts from absolute zero, because at absolute zero all objects including particles are theoretically stationary, so there is no entropy, once it breaks through absolute zero, the object begins to move, and the chaos of the system increases, that is, there is entropy, and all systems with entropy have heat, so it is said that heat starts from absolute zero.

Absolute zero embodies the existence of matter, i.e., fluctuations (vibrational and thermal motion) are always present; The speed of light reflects the locality of the force, and it is impossible to achieve the action at a distance, and the propagation rate of the force is always limited. They all point out that there is no such thing as an infinite quantity in real physics.

Fourth, Planck's constant.

The symbol h is a physical constant used to describe quantum size, which plays an important role in atomic physics and quantum mechanics.

The values are approximately: h = (33) 10 (-34) j·s

5. Is the answer to the ultimate question of the universe and the universe the number 42?

Absolute zero and the speed of light are both the limits of the universe, some kind of limit? And who sets this limit?

There is no direct relationship between numbers and the universe, and the digital universe refers to the use of digitization to measure the universe.

It's like asking astronomy and geography again.
