Why is gravity down instead of upward?Scientists give the answer, after reading it, I understand

Gravity is the reason why everything has quality or energy, which makes everyone intoxicated. This also explains why Apple dropped to the ground and why the planets rotated around the star.

Gravity can attract some metals, but gravity can also exclude other gravity. So, what kind of feel will you feel if you are only affected by gravity tension?

In 1915, Albert Einstein published a general theory of relativity and answered this question. The reason why gravity is pulled to the ground is that all objects have the quality. Just as our earth, these objects are bent the structure of the universe, that is, space time. The curvature is your feeling of gravity.

What is space time?

Before understanding the complex gravity world, you need to understand space time.

Space time is actually the fourth dimension of space, that is, except for the three dimensions of length, width, and height. Einstein was the first person to recognize the physical world rules in the universe through an excellent mathematical calculation method, that is, in space, time and space are fused.

In other words, time and space are interconnected. If you move in the space fast enough, then your time will slow down compared to other people with a slower speed. This is why the fast -moving astronauts in space will be a bit slower than people on the earth.

The earth is bent in space time, so you will fall back to the earth instead of leaving the earth.

The material forms a gravity well, not a gravity mountain.

Remember that gravity is a mutual attraction that objects in space are bent due to space time. In Einstein's general theory of relativity, he said that all space substances can distort space time. The material here is the quality and energy of physical terms.

Because your brain always knows the world from three dimensions, it is difficult for you to use the fourth dimension of space time alone to understand the world. To make this explanation more image, you can imagine the surface of a trampoline. If there is nothing on the trampoline, then it is flat. However, if you are standing on the trampoline, it will be depressed around your feet and form a depression pit with you as the center. If you put a ball on the trampoline, then this ball will roll to your feet.

This is a two -dimensional example running for space time. Your heavy weight causes the trampoline to depression, and the so -called gravity prompts the ball to roll towards you. This is very similar to the working mechanism that pulls the heavy objects like you and me, just like our earth.

In order to make things more interesting, we can consider that because time space is interconnected, time will also distort them due to heavy objects.

The heavier you, the deeper your trampoline is depressed. This is why the very heavy material in space such as the sun or black hole will be greater than the gravity of the earth.

So why do gravity pull you to the ground instead of pushing out?

Imagine a scene where a person jumps from the trampoline and plays at the high altitude. At the moment you play, the ball will fly away, and at this time, a gravity well is formed instead of Gravity Valley. As scientists know, quality or material always forms a gravity well rather than a gravity mountain. Of course, scientists can also imagine an object composed of extremely heavy quality or energy, which can throw you into space. However, until now, no one has discovered this.

Gravity (English: Gravitation/Gravity) refers to the role of attracting each other with quality objects and the source of object weight [1].

Gravity and electromagnetic, weak interaction, and strong interaction constitute the four basic interactions of nature. Among these four basic interactions, gravity is the weakest, but it is also a long -range effective force [2]. In modern physics, gravity phenomenon is generally accurately described by general relativity theory, and believes that gravity reflects the manifestation of the inertia of objects in the bending space -time. The law of gravitational gravity in classic mechanics is an excellent approximate description of gravity under normal physical conditions.

On the earth, the gravitational gravity of the earth to the earth gives the object weight and put the object to the ground. In the universe, gravity allows material to gather to form celestial bodies, and at the same time, it also attracts each other to each other, forming an celestial system that runs according to the track. In addition, the gravity of the moon and the solar on the earth on the earth formed a tide on the earth.
