In the unremitting efforts to find aliens, some people have come up with a refreshing hypothesis. They believe that the alien world with advanced intelligent life is not far away in the sky, but in our solar system, and has the same orbit as the earth, and is the real sister planet of the earth, which we call "b earth" for the time being. It's just that because the planet is located directly opposite the Earth, and it orbits the Sun at exactly the same speed as the Earth, the relationship between the Earth and the B Earth is like hide and seek, and the "gate" of the Sun is forever blocked from view, and no one can see anyone.
They also believe that since the earth has the same orbit and the same distance from the sun, it will have the same external environment and a similar material composition, so it will also have the same conditions for the occurrence and development of life, and will give birth to and reproduce higher intelligent beings like the earth. Since there are many accidental factors in the development of life and high technology, even on the same planet, there will be differences between advanced and backward, so we should not expect that the people on earth will have the same level of knowledge as us, and it is very likely that they will be more advanced than us, so that they may master far more advanced space flight technology than us, and the confusing UFOs are the vehicles they send to reconnoiter the earth.
According to the theory of celestial mechanics, the existence of a celestial body must have a gravitational connection with the surrounding celestial bodies. For example, there is a huge gravitational connection between the earth and the sun. According to Newton's law of gravitation, the magnitude of the gravitational force is directly proportional to the product of the masses of the two and inversely proportional to the square of the distance.
Why, then, is it that the sun and the earth are not getting closer and closer to each other? It turns out that this is also related to the rotation of the earth around the sun, because the centrifugal force generated by the rotation is exactly equal to the gravitational force, so the earth neither fell into the sun nor flew away. It's like we're tying a stone to a rope and then rotating it quickly with our hand as the center and the rope as the radius.
At this time, the stone will remain in a circular orbit due to the influence of the rotating centrifugal force and the control of the rope.
b The earth must always maintain the same orbit and rotation speed as the earth, and not face the earth, and it must also have the same mass as the earth in order to meet the conditions that gravity and centrifugal force are equal. However, according to Bode's law, there is a certain law in the distance between the planet and the sun, and in the orbit of the earth around the sun, only the earth is allowed to exist.
Taking a step back of 10,000 steps, if there really is such a b-Earth, although it is separated from our earth by a huge sun, and under the cover of the sun's gravity, the earth's gravitational pull may not be easy to detect, but its existence must have an impact on small celestial bodies in space, such as detecting its existence from the changes in the orbit of a comet flying close to b-earth. But in fact, no one has ever observed such a change. It can be seen that the bearth is pure speculation of some men.
-
What kind of bearth, if in terms of size and quality, there should be, because the universe is so big, there will always be. If you ask about antimatter, I believe there will also be a planet made of antimatter.
-
Scientists have recently discovered planets that are about the size of Earth, and in every galaxy the size of the Milky Way, there will be a planet about the size of Earth.
-
Definitely not! Imagine if you were holding two ropes of the same length in your hand, with an object tied to each end of the rope, and when you threw the rope up, the two objects would surely collide! In the same way, if there had been a bearth, our present earth would have been destroyed by the impact a long time ago, would it still survive to this day?
-
There should be, it should be planet b, the universe is so big, there are at least hundreds of thousands.
-
There won't be, there's only one on Earth, and there's no second one.
-
Is there a "second Earth" in the universe? It's not impossible, NASA is already on the move.

The basis for the birth of life is organic matter, and organic matter must be composed of at least oxygen, nitrogen, hydrogen, carbon and other elements. Then, there are certainly not a few planets in the universe that have these elements, as long as there are suitable conditions, these elements can be combined into organic matter, and then these organic matter is constantly evolving, and finally life is born.
Take the evolution of life on the earth as an example: the oxygen, nitrogen, hydrogen, carbon and other elements on the earth form proteins under the action of the sun's ultraviolet rays and thunderstorms; It is also a coincidence that the earth is at the right distance from the sun, so there is life. Life then evolves further due to the constraints of the environment.
Then after n billion years of evolution, humans were born.
There are trillions of planets in the universe, so there must be a few in the universe to find a place with similar geographical conditions to the earth. Therefore, we cannot say that there are no life forms other than the earth.
-
There is a theory that on the other side of the sun there is a bearth, rich in matter and also suitable for the survival of man. And does this bearth really exist?
According to the theory of astronomy, the existence of a celestial body will inevitably have a gravitational connection with the surrounding celestial bodies, just like the sun and the earth, there is a huge gravitational connection between them, so the result of the sun and the earth attracting each other, is it getting closer and closer? Of course not, this is also related to the centrifugal force generated by the rotation of the earth around the sun, as if we use a rope to tie an object and rotate rapidly, at this time, because the centrifugal force is equal to the pulling force of the rope, the object will always adhere to the same orbit around the center, and the same b The earth must always be in the same orbit as the earth, and must have the same mass as the earth in order to meet the condition that gravity and centrifugal force are equal, but according to Bode's law, in the orbit of the earth around the sun, only one planet is allowed to exist. Therefore there is no bearth.
-
Theoretically it does not exist, human technology can already know the condition of galaxies tens of thousands of light-years away by observation alone, and there is no so-called Earth B at present, even if it is discovered, it is a question whether humans can reach the instrument. But people's observational calculations are always biased, so maybe they will find it.
-
There should be, there may be overlapping spaces in parallel worlds!!
How long is the life span of the earth? The Earth is speculated to have survived for 4.6 billion years, but how long will it live? Scientists believe that if the Earth is allowed to move freely, it may exist forever, but if other external factors interfere with it, the Earth may have an end of life. >>>More

1. Is there really a magnetic field bump at the poles?
Yes, it really exists. In 1845, the German mathematician Carl Gauss began to record data on the Earth's magnetic field, which is nearly 10% weaker today than then. And that momentum is set to continue. >>>More
Earth is the third planet in the solar system from the inside to the outside, and it is also the terrestrial planet with the highest diameter, mass, and density in the solar system. It is also often referred to as the world. The English word earth comes from Old English and Germanic languages. >>>More
