Is it matter or space that expands the universe?

The universe expands into space and has nothing to do with matter. The universe is constantly expanding from moment to moment, but the change of space has nothing to do with matter itself.

Because of the expansion of matter, space must be expanded, and the expansion of space must be accompanied by the expansion of matter. Both are supposed to be changing.

The universe is indeed expanding, but it is definitely not matter that the universe is expanding, but the space of the universe, which will make the space of the universe infinitely enlarged and boundless.

The universe is vast and infinite, boundless, beginningless, and endless. At present, the universe as human cognition is limited to the theory of the formation of the "universe **". The center of the big ** is the "black hole", after the big ** the universe begins to expand around, after the end of the universe expansion, the black hole begins to shrink, and absorbs all the stars in the universe, matter, including light, in the center of the universe to gather and squeeze.

Eventually, a new "big **" occurs, giving rise to the new and the universe. And in this way it will loop forever and infinitely.

In order to solve the mystery of the universe, the mystery of black holes will require continuous research and exploration and discovery by human beings in the future.

What does it mean that the universe is expanding, that space is expanding? Let me answer that many people speculate based on some principles or theories that the expansion rate of the universe after the universe is greater than the speed of light, which is caused by the expansion of space. If the matter of the universe expands at no faster than the speed of light, the radius of the universe of nearly 14 billion years will naturally not be greater than 14 billion light years, while some people believe or speculate that the radius of our visible universe can reach tens of billions of light years, or even more than 90 billion light years.

Of course, this is only the size of the visible universe, and there may be a larger space or more matter belonging to our universe outside the visible universe, but it is too far away from our galaxy for matter outside the visible universe to affect us, and we cannot observe it. In short, the fact that our universe is so large and the timing of the birth of our universe does not seem to be very controversial can only show that our cosmic space has expanded, and it is the expansion of space, which is not the same thing as the expansion brought about by the diffusion of matter. Now let's ** let's **, what is the cause or essence of the expansion of the universe?

I don't know how others explain the expansion of space, but we should be able to explain or understand the expansion of space according to the principle of relativity. According to the general theory of relativity, it is inappropriate for us to say only space, it should be space-time, that is, the fusion of time and space. Space-time is the first to matter, and matter produces space-time.

Our space-time density is consistent with the density of matter, and the space-time density of the local area depends on the density of the matter in the local area, and the extremely dense density of matter corresponds to the space-time density that may be equally dense. The density of space-time determines the speed at which time travels, and in dense space-time regions, time travels extremely slowly. The density of space and time determines the density of space, such as the length of space or the volume of space units, in a dense space-time region, the volume of space units is very small, and the length of space units is also extremely small, for example, the length of the same kilometer is extremely small in dense space.

Explanation of the term Explanation of the Expansion of the Universe: Refers to a view of the universe by some scholars based on the results of the deduction of the general theory of relativity. Based on the shift of the spectral lines towards the red end (i.e., the higher wavelength end), they argue that the universe is expanding like a balloon.

In astronomy, redshift generally refers to this phenomenon observed in the spectrum of extragalactic galaxies. The farther away galaxies are, the greater the amount of redshift, and according to the general theory of relativity, there is a redshift in the spectral lines in a strong gravitational field. If the redshift is due to the Doppler effect, the speed at which the extragalactic galaxy leaves the observer increases by about 16 km-seconds for every 1 million light-years of distance, indicating that the light source is moving away from the observer.

Some astronomers have based this on this to believe that the universe is expanding.

Some people believe that the redshift phenomenon is due to the energy consumption of photons in the long propagation distance, so the frequency becomes smaller, and the spectral line shifts to the red end. Some people think that the redshift of galaxies is a property of space-time, and cannot simply be regarded as the Doppler effect, and the conclusion of the expansion of the universe is drawn from the conclusion that the redshift is a Doppler effect, and some people think that even if the redshift is a Doppler effect, it can only indicate that the total galaxy where the galaxy is located is currently expanding, and cannot be considered that the universe is expanding, and the two cannot be confused, because the universe is infinite, and there is no expansion or contraction.

The cosmic hypothesis holds that the universe begins with a singularity and then begins to expand.

Under the action of the universe, the infinite distortion of space-time at the singularity instantly expands around the singularity, and the expansion of the universe and its space is a form of realizing its transformation of time and space, mass and energy.

Based on the argument that "the universe is expanding", some people believe that the universe originated from a big **. About 18 billion years ago, only 10 25 centimeters in size of the ultra-high-temperature, high-density universe suddenly**, and then the universe began to expand, the temperature began to drop from billions of degrees Celsius, about 55 million degrees Celsius, by the energy of the cooling process, the generation of neutrons, protons, and they merged into atomic nuclei, these processes only 3 minutes. About 300,000 years later, when the temperature of the universe drops to 3,000 degrees Celsius, free electrons are captured by the nucleus to form atoms.

Over the next 30 million years or so, the atoms continued to rush outward, and the universe continued to cool, until the cosmic temperature dropped to 167 degrees Celsius above absolute zero, and the atoms coalesced to form a thin gas. Since then, due to density fluctuations and gravitational effects, some shrinking bodies have evolved into new celestial bodies.

Indeed, yes, the expansion of the universe creates space, and space does not appear out of thin air, which is also in accordance with the law of conservation of energy.

Because the main basis for the expansion hypothesis of the universe is the Doppler effect observed by Hubble between galaxies, the Hubble redshift.

Therefore, Hubble's law only describes the law of mutual regression between galaxies, not the law of the expansion of the universe.

Because the main base of the universe is the vacuum, the expansion of the universe is the expansion of the universe, and the expansion of space is the expansion of the vacuum field. As a result, there is no longer a single stable particle in the universe.

I believe that the creation of space must have a certain relationship with the universe, and only when the planets in the universe are operating normally will the emergence and safety of space be guaranteed.
