Yeah, and we won't survive without the sun...

Um... generally, the smaller the Sun, the hotter it burns, and the larger it is, the weaker... So if it starts to "expand," we're more likely to face an ice age than the opposite – it will start to shrink and turn blue (such suns are hotter), and then it will burn us... and then explode...

Yeah, and we won't survive without the sun...

It's all nonsense (at least for now) - first, how will they be able to build something like that, and what materials will they use so that all these engines can withstand the gravitational pressure that could move the Earth... most likely, they will all simply fall apart. Secondly, how can they even hope to restore the orbit around the sun...

At the moment, all such plans are pure idiocy...

I agree with that. First, the Earth will freeze, and then the Sun will become so large that it will simply absorb the Earth (or, more precisely, when the star is close enough, the Earth will evaporate). However, due to the decrease in the Sun's mass (which loses 4 million tons per second), the Earth's orbit will increase, but it is not certain that it will increase faster than the size of the star. But even now, scientists with their supercomputers cannot say for sure what will happen in "several billion years."

http://www.astrogalaxy.ru/277.html, the fourth point, but I definitely greatly exaggerated about 30 years. At the moment, this is indeed not feasible, but, in my opinion, it is not nonsense and certainly not idiocy.

I read point four. It's still nonsense... They don't consider whether the structure can withstand a gravitational shift... As for how many times the engines will be launched, it certainly won't be every day, but rather a few times a year, because the sun isn't "exactly above the equator" every day. What will happen to people while the planet moves at this pace?... And the finale - a satellite of Jupiter - do they even understand how absurd that is?! As soon as we move into Jupiter's shadow, we'll all freeze!

P.S. He's a physicist... He understands physics, but judging by all this, he's as far from astrophysics as he is from Alpha Centauri right now...

The Sun's mass is insufficient for its evolution to culminate in a supernova explosion. Instead, in 4-5 billion years, it will turn into a red giant star. As the hydrogen fuel in its core is depleted, its outer shell will expand, while the core will contract and heat up. In approximately 7.8 billion years, when the temperature in the core reaches about 100 million degrees, a thermonuclear reaction will begin, synthesizing carbon and oxygen from helium. At this stage of development, temperature instabilities within the Sun will cause it to begin losing mass. Apparently, the expanding outer layers of the Sun will reach the current orbit of Earth at this time. However, research shows that even before this point, the Sun's mass loss will cause the Earth to move to a more distant orbit from the Sun, thus avoiding being engulfed by the outer layers of solar plasma.

Despite this, all the water on Earth will turn into a gaseous state, and most of its atmosphere will dissipate into space. The increase in the Sun's temperature during this period is such that, over the next 500-700 million years, the Earth's surface will be too hot for life to exist in its current form. In this regard, interstellar travel will undoubtedly become essential for the survival of humanity.

Well, in general, over the course of a year, the Earth's movement away from the sun will occur in the plane of the equator, although specifically, this will only happen on the days of the equinox. As far as I understand, each of the engines will need to be activated once a day. The entire structure of one of the engines, together with the tower, should only withstand the load created by the engine and its own weight. Perhaps this is possible. And nothing particularly terrible will happen to people, as long as they start on time. And I don't think it says that the Earth should become a satellite of Jupiter. It should only move away from the Sun to the distance where Jupiter's orbit is located.

Actually, here.
