The outside can t get in, the inside can t get out, what is it that covers the solar system?

However, when human beings explored the solar system, they found that there seemed to be an invisible cover in the outer periphery of the solar system, which was actually a planetary belt composed of some small celestial bodies. Firmly encircled at the edge of the solar system, scientists believe that this natural barrier, the Kuiper Belt, should be the outer layer of protection around the solar system. Passing through this protection means that we have reached the outer reaches of the solar system.

Because there is a nebula around the solar system, this nebula has a very large radius of 20,000 light-years, which in turn covers the solar system.

It is an invisible layer of energy that envelops the solar system, causing the solar system to be cut off from the galaxies outside.

Question 1: Do you think that everything outside the solar system is fake The question you think most people think about The existence of time and space and the real world There is evidence that the world exists Your definition is not the definition of the majority of people and it is not logical.

Question 2: How can it be said that there are no resistors on any planet in the solar system except for the Earth?

Question 3: Has there been a planet that can live outside the solar system (there is no outside the solar system, there is one in the solar system) A few days ago, foreign media reported that as early as late April this year, the French National Center for Scientific Research, as well as relevant research institutions in Switzerland and Portugal, announced at the same time that a research team composed of astrophysicists from the research institutions of the above three countries had discovered a "habitable planet" with similar conditions to the earth at a distance of light years from the earth. Although there are still many unknowns about this stone, the existence of this planet has been completely confirmed by researchers after more than 50 observations and repeated verification calculations in the past three years.

According to available research, the mass of the planet is about 5 times the mass of the Earth, and its mass analysis should be similar to that of the Earth, with a surface composed of either rock or water, or both. In addition, its surface temperature should be between 0 and 40 based on its distance from the red dwarf, which is suitable for life and allows water to exist in liquid form. Therefore, they speculated that the planet was "habitable" from conditions such as possible solid land, liquid water, and suitable temperatures.

But this is just speculation. Because, with the current technical means, they have no way of knowing the atmosphere of this planet.

As for the reasons for the lack of "eye-eye" observations, he explained: "The current observation equipment is still far from this level, but we have accurately calculated the mass and distance of the planets affected by it based on the degree of deviation of the orbit, the change in velocity and the period. Therefore, the researchers believe that people want to "move" to the fantasy of "super-Earth", because with current technology, even the fastest spaceship can take hundreds of thousands of years to reach the planet from Earth.

Question 4: Why does Water Jupiter have rings outside I search** There is no ring outside the other planets in the solar system There is a spring outside Jupiter Mercury has no rings, Jupiter, Saturn, Neptune, and Uranus all have rings, and Saturn's rings are obvious.

Question 5: Does the galaxy refer to the outer solar system? Galaxy, galaxy, universe also. The meaning is extremely numerous, extremely wide, infinite mysterious, and endlessly profound.

Stars, the essence of all things, luminous celestial bodies, describe the light to be dazzling, numerous and prosperous; River, a collective term for rivers, has a broad and far-reaching meaning. The galaxy, the galactic universe, is vast and far-reaching, extremely numerous and wide, and the mysteries are endless.

Although we can't go out, the technology developed by our country can go out to the solar system, and naturally we can know what is going on outside.

It is because we have many satellites and electronic cameras in space, constantly observing the outside world and feeding back this information to the earthlings.

Because human beings have been exploring space all the time, they have discovered many celestial bodies outside the solar system.

Because we have invented a lot of satellite probes that can detect things in the universe, we also know a little bit about things outside the solar system.

Because we have advanced astronomical telescopes and are backed by scientific theories, we can know things outside the solar system.

Because of optical telescopes, he can see planets beyond the solar system. So we can know beyond the solar system.

We humans can't go outside the solar system, but we can study things outside the solar system through scientific and technological means, and maybe when the technology matures, we can reach the outside of the solar system.

We know this through astronomical telescopes, especially the Hubble telescope. Our gaze can extend even more until we see the Milky Way, and even beyond, which is also the result of the efforts of our scientists.

Sometimes knowing something is not about seeing with certainty, and many things are obtained by speculation, so this kind of thing is not so certain.

Although we can't go out of the solar system, with the support of telescopes and some physical theories, we can see a limited amount of cosmic space, and of course, we can speculate on more distant galaxies.

We sit at home and don't go out, because it's a severe time for the coronavirus, but we can still know about national events, we can still know a lot of things abroad, why?It's because of the development of science and technology.
