If the earth is as big as the earth, what will human life be like?

Before 20 12, the human world? Maximum volume star? The record holder is a VY dog 3900 light years away from us.

However? There are stars outside the star? Vi Canis, the first one on the list, was quickly replaced by the shield of uy 5 100 light years away. As a red Supergiant star, although the life span of shield uy is only10,000 to 50 million years, its volume is 5 billion times that of the sun. If the shield uy and the sun are exchanged, all the celestial bodies in Saturn's orbit are new suns? Shield uy swallowed it.

In the current solar system, electromagnetic waves traveling at the speed of light can circle the earth 7.5 times in one second, but it takes 14.5 seconds for electromagnetic waves to circle the sun. As a star that can accommodate 50 suns or 6500 trillion earths, it takes 6.9 1 hour for electromagnetic waves to go around shielding uy.

If the earth has the size of shield uy, will it be considered? A sharp increase? Under the condition of gravity, people living on it can only fly from one end of the earth to the other by plane 1387, if the land traffic is slower.

In addition to the inconvenient transportation, in? Uy shield? On the earth, the network will also become very, very slow, because in our universe, the upper limit of information transmission speed is the speed of light, and the speed of electromagnetic waves is already the speed of light, so it is 6.95438+0 light at the equator? Earth? In fact, in the human world, the efficiency of all behaviors that require electromagnetic waves will be greatly reduced, and there will be a delay of tens of minutes or even hours.

So far, what about the earth? Huge? The only advantage is rich resources and land. Land suitable for human development and life can be found everywhere on the huge earth. Even a primitive island can feed some wood resources and metal resources needed by all mankind.

Dialectically speaking,

Is the enlargement of the earth actually man-made? Miniaturization? If future technology can shrink all animals (including humans) on the earth by 10 thousand times, the proportion is the same.

Poverty, hunger, energy?

What are these three problems that have long plagued human civilization? Small world, huh? Will cease to exist

Liu, a science fiction writer, wrote a short story called Micro Age. In order to survive the solar crisis, the human civilization in it chose to shrink itself to the size of bacteria, so that any resources in the big world can feed these? Micro people? Kid.

Moreover, Liu also believes that miniaturization and miniaturization are what advanced alien civilizations should look like. So in the future, human beings may encounter some spacecraft the size of golf balls in the universe, but there is an entire alien civilization living inside.

Get down to business

From a scientific point of view, it is impossible to have a planet with the size of shield uy in the universe, because when the mass of the planet reaches 0.08 times that of the sun, the internal temperature and pressure will trigger a nuclear fusion reaction, thus turning the planet into a long-lived red dwarf.

To take a step back, even if there is a planet the size of shield uy in the universe, will the huge gravity brought by the huge mass crush it? Small body? Humans.

abstract

The shield constellation uy is the largest star ever discovered. Will it be ruled out in the future? Kick off the list? This possibility is not even ruled out? What is the upper limit of the planet's volume? The possibility of being refreshed.

Anyway. The universe is very big, and anything is possible without violating the laws of the universe?
