What is space and time like?

We walked on the main road, up and down, left and right, front and back space. Space is immovable. And time is moving, whether we want to or not, whether we want to or not, time is moving forward, and human time is limited. When the age reaches its limit, the body will age on its own and then die.

So, space and time seem to be separate. No, from this it seems that they are separated.

However, when studying the light, I found that this so-called common sense is wrong!

Space and time exist at the same time and are interconnected.

Time slows down as the speed approaches light. When I fought with the Linghuo Dao people for the last time, time slowed down. Later, I learned that it was my eldest brother who pulled me into another inertial frame, an extremely fast inertial frame, which made me see the slow-moving spark from that inertial frame and experience the arrival of death for a long time.

speed, moving in space. Fast to the extreme, you can move through time. However, the speed of light seems to be the only true speed, and it cannot be exceeded at all. That is, it is impossible to go back to the past. crossed over and became nonsense.

Originally, photons have no mass. But when passing something of great density, mass, the light is deflected. In order to verify whether the light has mass, the eldest brother measured an extraterrestrial aurora, and when this light passed by the sun, it was deflected for 1.7 seconds. That's why there are experiments that use small black holes to observe photons.

There is a kind of coercion in the Dao Realm itself, that is, the coercion of mass density. The body of the Dao Realm is extremely heavy, but it is still the size of an ordinary person. When they don't have control over the force field around them, they will oppress the people around them. Ordinary people will die directly. It's like a meteorite is attracted to the earth and burns up before it reaches the earth. Therefore, the Dao realm is like the sun in people, and it is obvious wherever you go. Later, the control of the force field learned by the Dao Realm distorted the surrounding space, and also slowed down his own time. This is the biggest reason why the Dao realm lives long.

The force field, which attracts light, distorts space and time. Theoretically, it is possible to live forever. But their mass is still too far from the black hole, and the distortion of space-time is still too weak.

The eldest brother later told me that his Dao realm was opportunistic because of this. Instead of approaching the Dao realm according to instinct, it is better to study nature and grasp the laws to enter the Dao realm.
