A question of time, what is a question of time?

Time and space are all produced by motion, which means that time and space have a physical meaning when all objects have relative motion. Otherwise, when all objects have no relative motion, there will be no physical significance, only mathematical significance.

What is only mathematically meaningful, it has no meaning for us humans. Because there is only something mathematically meaningful, which we did not find to be real, but only "invented" by us.

Therefore, if all matter stops moving, it will cease at any time, and this statement is true.

This statement is both true and false. Because the conditions are wrong, or the conditions do not exist, the wrong conclusions will be drawn; But if the condition is hypothetical, it is the assumption that something that does not exist or will not happen will have what the consequences will be if it happens.

I feel like your assumption is valid, but that probably won't happen.

This involves two views of time: the "tense theory" and the "non-tense theory".

Tense theory holds that there is only one "now" and that time exists dependent on the motion of objects.

The theory of temporality holds that time has an infinite number of "nows", and time is a dimension of objective existence.

Look at you as a proponent of that theory.

Time is only a scale, it exists dependent on matter, and even if matter stops moving, time still exists!

Time should be caused by the expansion of the universe itself, and if the universe stops expanding or the universe stops moving, probably time will also stop. It's like the blood will stop working unless the person dies, but as long as the person does not die, no matter what happens, the blood will not stop and not turn.

It should be right in theory, but in fact it is completely impossible.

Albert Einstein said in his theory of relativity about the relationship between time and motion, if the speed of motion is close to the speed of light, time almost stops.

If the speed of motion exceeds the speed of light, time can even be reversed.

But there is no such thing as an absolutely static substance.

Rest is relative, motion is absolute.

These examples demonstrate the idea that time is not an issue:

The first example is that Professor Shepiro found a problem in the whirlpool of bath water, and through repeated trials and studies, he found that the direction of rotation of the whirlpool of rotten wax water is related to the rotation of the earth.

The second example is the famous British hunger chemist Boyle accidentally discovered that hydrochloric acid can turn flower petals red, and then conducted many experiments, and finally invented the acid-base test strip.

Background of the creation of "Truth Is Born After a Hundred Question Marks":

Truth is Born After a Hundred Question Marks" is an essay written by contemporary writer Ye Yonglie in 1981.

Ye Yonglie (1940- ) pen name Xiao Tong, Jiuyuan, etc. A popular science scientist, a writer of biographical literature, he is the main author of "One Hundred Thousand Whys". A native of Wenzhou, Zhejiang, he graduated from the Department of Culture of Peking University in 1963.

Summary. Hello, it's an honor to answer for you

Please briefly describe your problem.

Help me answer the time question.

Hello, it is an honor to answer your question Brief description of your question.

8:00 hours + 8:30 hours + 8:

30 hours + 4: 30 hours + 10:00 hours + 9:

00 hours + 8:00 hours + 10:00 hours + 8:

00 hours + 10:00 hours + 8:00 hours + 4:

30 hours + 9:30 hours + 10:00 hours + 8:

30 hours + 10:00 hours + 10:00 hours + 9:

00 hours + 8:00 hours + 8:00 hours + 8:

00 hours + 8:00 hours + 8:00 = how many hours.

Hello, are you offering this time or hours? That is, 8:00 is 8 hours or 8 o'clock.

Dot. You're not right, if the time should have an interval value, the time is 24 hours, according to the time you give it, it's 194 hours.

Do the math. 194 Ha You don't give this value completely, like August 5 you only gave 8:00 (start time), you should also give an end time.

Or is there an interval from 8:00 on August 5 to 4:30 on August 6?

It's all in one place.

I know it's all counted together, and I mean each row is a time frame, right? Wait a minute.

Answer: The next time the two needles are at right angles, which is equivalent to the minute hand chasing the hour hand, and the two needles are still at right angles, but at this time, the hour hand is in front.

Speed of the hour hand = 360 12 = 30° Hour = minute.

The speed of the minute hand = 360 60 = 6° minutes.

After x minutes, the two needles are at right angles, then.

9×30＋½x－6x=90

Solution: x=360 11

The next time the two stitches were at right angles, 360 11 minutes passed.

The hour hand rotates every minute.

The minute hand turns 6 degrees per minute.

The next right angle must be between 9:30 and 9:35, with the minute hand in front of the hour hand (the minute hand at 9:00 is after the hour hand).

Then the degree of the minute hand = the degree of the hour hand + 2 * 90 degrees.

X minutes have passed.

6x=Solve the equation. Get x = 32 and 8 11

It's a matter of pursuit. Minute hand speed 6° Minute hand speed The distance to be pursued by the minute hand is 180°

180 ( min.)

At 9:30, I looked at my watch and I knew, and after 30 minutes, I wish! Thank you!
