This is Archimedes' famous saying. According to his lever principle, the fulcrum is well chosen and the ratio of the two arms is large enough. No matter how heavy this object is, even the earth can move by itself. By extension, some people can conquer nature. Knowledge and wisdom can solve all seemingly impossible things, and there is also a little rhetoric in it.

But now some people regard this sentence as a kind of irony, because it can be done in theory, but it can never be done in practice. Is empty-handed, talk big. Actually, I can't. The mass of the earth is greater than the 24th power kilogram of 10, and the mass of 1 is the 2nd power kilogram of 10. If we want to tilt the earth with this person's mass, it means that the lever length on this person's side will be more than the 22nd power of 10 on this side of the earth. If this person puts the lever at 1 s, 1 m is equal to the ninth power nanometer of 10, and 1 nanometer is a little larger than an ordinary atomic radius. You will find that this person presses the lever down at a speed of 1 m per second for one year, and the earth is raised by less than 1 atomic radius!

Besides, you can't find such a long lever!
