If you travel faster than the speed of light, you will go back in time

It seems that we can understand it this way!

There is a saying that the speed of motion is greater than the speed of light, but classical physics tells us that there is no object or matter that moves faster than the speed of light, and of course it is possible to travel back in time through wormholes! This is only a theoretical hypothesis, and the actual proof is not sufficient!

For the human mind, philosophically it is not an object or a substance, and in reality it does not seem to be a material object! However, if we assume that thoughts are material, then recalling the past is a kind of time regression!

To talk about my understanding of time, I hope it will be useful.

I think time is a description of things that are used to describe changes in objects, substances, and so on.

If nothing changes, I think time stands still. Of course, it's impossible for nothing to change, light moves through space, weak electrical signals pass through the brain, and the planets don't move anymore all the time.

So I think it's not quite right that the supplementary question says that all the changes in the world are done through time, but that all the changes in the world are described in time. I think there is no time without change, and time is dependent on change.

And what about the human mind? I think it's caused by some very weak electrical and chemical signals propagating through brain cells. Going from the north side of the earth to the south side of the earth is actually just a signal in the brain for a moment"Vibration"I don't think the speed of this signal will exceed the speed of light.

It's true that sometimes you feel the speed of thought, but I don't think it's the same as the speed of light, the speed of light is a physical quantity, it's the movement of matter. Thought is a feeling, a chemical change. You can imagine shaking from Nanjing to Bull Wolf without moving in a physical sense, can you say that you are more than the speed of light?

Also, I think of time as a reference, a fundamental quantity that we find to refer to ourselves and describe things. Time is eternal, you say "all the changes in the world are done through time, there is no time, everything will not age, then he can't remember the changes of everything, is it the same as not feeling time" is your own feeling, and time does not have any pause or change, can only say that your subjective opinion is not an objective existence.

Time? What is time?

It's not yet a human definition (1 second for a long time, 1 minute for a long time), it's a void! But time only goes forward, and at a constant pace.

It is impossible to speed up or slow down.

It will not go backwards.

Time is man-made! Know no.
