Is there a scientific basis for "Wandering Earth 2" to blow up the moon?

It is still possible to blow up the moon.

In Liu's original novel, the moon was just pushed away by the planetary engine so as not to interfere with the long journey of the earth. The human plan in the movie was originally like this, but the lunar planetary engine was out of control for some reason. The moon was not pushed away, but pushed to the earth. In order to avoid collision, we have to blow up the moon.

In the film, the flame emitted by the engine is blue in normal operation, turns red when it is overloaded, and finally explodes when it can't bear the overload operation. This color matching accords with people's intuitive feeling of color, but it doesn't accord with physics: the temperature corresponding to blue light is higher than that of red light.

How to bomb the moon;

The scheme adopted in the film is to set more than 3,000 nuclear bombs on the surface of the moon and detonate them at the same time. It is actually very difficult to bomb the moon by violence alone. I can't help it The moon is a huge lump. It is the fifth largest satellite in the solar system, bigger than Pluto. Its total mass is 1/8 1 of the earth, which is equivalent to the sum of all water on land, sea and air multiplied by 60.

Such a large mass is enough to keep spherical by its own gravity, so it is almost useless to blow up a super pit or something, and the fried fragments will roll back into the pit by themselves. Even if you use the Force and split the moon in half with a sword, you can hardly see the difference-under the action of gravity, the two halves will still stick together.
