The earth has been floating in space, why does it weigh 60 trillion tons, but it does not fall down?

I believe many people know that there are many unsolved mysteries in the world, nature is very wonderful, and there are many unknown areas in the universe that humans have not yet explored. Although current knowledge is sufficient to explain most phenomena, many things cannot be explained clearly by current theories. Even if things like universal gravitation, the propagation of light, and Newton's theorem can explain most natural phenomena, these are all verified through countless experiments. How much does the earth weigh? Experts have calculated that the total weight of the earth is about 6 billion tons.

From the perspective of the universe, the earth is suspended in the universe, so why does it not fall down when it is so heavy? The earth has no fulcrum and no tray, so how is it suspended in the universe? In fact, even if there is a fulcrum, what kind of fulcrum can bear the weight of 6 billion tons. Everyone who has studied physics should know that in the absence of external force, an object will always remain stationary or move in a straight line at a uniform speed. In fact, the earth is not stationary, it is also in constant motion, the earth revolves around the sun at a speed of 30km/s, so people often say that although sitting still, it still travels 80,000 miles a day.

Many scientists have said that if the sun disappears or is destroyed, the earth will also be thrown out of the universe. Therefore, gravitation believes that the reason why the earth is suspended is because of the gravitational force of the sun on it. Newton believed that the reason why the earth is suspended in the air and will not fall is because there is an attractive relationship between the planets in the universe, attracting each other and repelling each other. But Einstein believed that the earth is actually slowly approaching the sun, but the speed is slow, and it is far away from the sun, so people are not easily aware of it.

The sun is the most massive in the solar system, so the earth revolves around the sun just like a man-made satellite revolves around the earth. It will fall towards whomever it revolves around, and the reason why the earth does not fall is because it revolves at just the right speed. The earth revolves around the sun and the moon revolves around the earth, forming a very wonderful cosmic balance system between them. Maybe no one can explain exactly why, but maybe that's the beauty of the universe. There is always something that you can't explain clearly.
