Even a spacecraft that currently reaches 7.9 kilometers per second takes 15 years to fly from one point to its opposite point. And the aircraft also has to face a problem, that is, the dilemma of insufficient fuel, you must know that the maximum range of ordinary aircraft is only 15,000 kilometers, to go from one place to another, you may have to go through many landings and refueling on the way.

If you are flying over the ocean, there is no place to land for refueling, and with the current means of human transportation, it may be difficult to cross the entire ocean. Human interaction will be very difficult, and most people will only spend their lives in very limited places, just like people in ancient times, unable to go out.

On top of that, the Earth is 6,500 trillion times larger, and we need to deal with the super-gravitational pull of supermass.

With the current physical quality of human beings, they will be directly pressed into cakes, and matter cannot exist in ordinary form.

It can be seen that such a huge planet cannot exist in the universe.

The mass of the celestial body determines the nature of the celestial body, and when the mass exceeds 10 times the mass of the Earth, the strong gravitational pull is strong enough to bind the ordinary hydrogen and helium, and the planet at this time will no longer be a rocky planet, but a gaseous planet like Jupiter.

If the mass is more than 75 times that of Jupiter, the strong gravitational pull is enough to ignite the hydrogen-helium fusion in the inner core, evolving into a star, no longer a planet.

The mass of a star cannot grow indefinitely, and it has an Eddington limit. When the limit is reached, the mass of the star can no longer grow, and although the mass of the star has a certain limit, its volume may reach a level that we cannot imagine.

UY is only the largest star that has been observed by mankind so far, and it may not be the largest star in the universe. It is possible that in the distant starry sky, which we have not yet observed, there are stars that are much larger than the constellation UY.

As for how large the planet can be, there is no definite conclusion at present. There are so many amazing things in the universe that are beyond our imagination.

It is possible that celestial bodies that were thought to be impossible to exist will be discovered by us in the future, and only by continuous observation and discovery, continuous research and exploration, can we continuously improve our cosmic cognition and enhance our scientific and technological strength.

When the tweet was posted, it became a topic of conversation after dinner for a long time.

You must know that this article is aimed at the Asian Space Force.

Although the main topic of the article is about the possibility of human survival on UY Shield, it has been straightforwardly explained from the beginning that a planet of the size of UY Shieldi cannot survive in ordinary planetary form.

At the very least, it must be in the form of a star in order to survive in this universe, otherwise it will be crushed by its own weight and collapse into a black hole.

These three words alone have already denied the fact that the Asian Space Force has announced the discovery of "a celestial body with a diameter of more than 500,000 light-years" in the traditional way of theory.

At the same time, on the basis of whether there is a possibility of life on a planet as large as UY in the constellation Shield, he once again made up for it from the side.

It can be said that this article is a direct attack on the current people's distrust of technology, which has caused such a big sensation.

At the same time, many people are now directly divided into two factions, both online and in real life.

One of them is to support the results of the announcement issued by the Asian Space Force, believing that this universe is full of unknowns, and human beings have not yet understood the earth, so how can they understand things in the universe?

What's more, it is a celestial body 1,018 trillion light-years away from the earth, and all that humans can see is 1,018 trillion years ago, and it is normal for the universe to be so big and full of things beyond human imagination.

On the other hand, there is a faction that is contrary to the view of supporting the Asian Space Force, commonly known as the opposition.

They believe that no matter how big the universe is, it is a large space composed of basic physical laws, and everything cannot be separated from the laws of physics.

Such a large celestial body has violated the theory of traditional astronomy, which is simply impossible.

Human science and technology have developed to a very high level, and they are the masters of the earth, even if human beings do not understand the things on the earth, but for the things in the universe, they are also in the tube, which can be seen.

If everything violates the most basic laws of physics, then it can prove that the world is extremely absurd.

Countless people spontaneously became members of both factions, citing a large amount of evidence to support their arguments.

This heated discussion began for a long time and set off a bloody storm all over the Internet.

So if you log on to Weibo at this time, you will find a very interesting thing.

The water army used to be rampant, and there were hot spots of trivial things everywhere, all of which were gone, and most of them became discussions about super-giant celestial bodies, as well as discussions about human technology.

And the star dramas that once occupied the entire page have all shrunk in one section, and the popularity is getting less and less day by day.

In such an environment, almost all of the traditional idol stars, except for those who are really good-looking and can attract a large number of brainless fans, have become obsolete overnight.

In addition to the supporters and oppositionists, there are also a large number of godly sticks who want to take advantage of this opportunity to develop believers and finally make a lot of money.

Some gods said, what kind of god's hometown is that, the gods are coming, and you can keep safe by paying XXX yuan.

Without exception, these gods have been severely attacked, no matter what, today and this New Year, these evildoers have to reflect on their lives in prison.

At the same time, there are also a large number of pessimists who have put together a bunch of examples, using real-life human technology as an example to exemplify a large number of conjectures that humanity will eventually perish.

After all, 1,018 trillion light years is too far away from humanity, so far away that it seems like an unattainable dream.

Even at full speed at the speed of light, it would take 1,018 trillion light-years to get there.

This universe is simply empty, empty to the point of horror, and human technology makes people feel deathly hopeless compared to it.
