A couple of potentially ridiculous questions, what is absurdity?

1. If there is only the suction force of the magnet, the combined external force is only the suction force, and there will be acceleration.

2. The charge passes through the center of the solenoid, which depends on whether the charge is positive or negative, the direction of the current flow of the solenoid, according to the right-hand rule, what direction the force will be generated, and the result is uncertain. Not necessarily accelerated. So this one can be considered your conclusion wrong.

3 Impossible, because the greater the speed, the closer it is to the speed of light, the smaller the size of the object will be, the slower the time, and the result will be that the charge will not be able to reach the speed of light, but will only become infinitely slower in an infinitely small space.

4. The problem of parallel universes is not solved for the time being.

5 Not counting the staggering of time and space, if we look at the Earth with a telescope at a distance of hundreds of millions of light-years away from the Earth, we may indeed be able to see dinosaurs! But this implementation is almost impossible, and it is theoretically feasible.

6 Your fourth question, for the time being, has no solution, 7 The mirror is just a reflection of light, which reversely extends the virtual image formed in the brain, where does the latitude of time and space come from?

8 The geocentric problem, due to gravity, gravity at the center of the earth can affect space-time, but the mass of the earth is not so large, if you say it, then the earth has almost become a black hole.

9 The problem of magnetic poles in the magnetic field, if this is actually analyzed, can be refined to the molecular current that produces the magnetic field, the same level touches, but the two atoms are close to each other, and vice versa, but the distance between the atoms is very large, and there is almost no effect on the atoms. Not to mention space time.

10 The nature of the ether, which man thinks is only a carrier of light, is not known.

11 Does the universe have an edge, what is outside the universe, no one seems to be able to explain your question now.

12 First of all, time stops if an object reaches the speed of light, and if the object moves faster than the speed of light, time goes backwards, but Einstein's theory of relativity tells us that no object can reach the speed of light, and humans are now looking for tachyon particles, and this question will not be known until there is a result.

Study hard!!

1.A charge passes vertically through a charged solenoid without changing velocity (electrodynamics). In addition, accelerating an object with a resting mass to the speed of light cannot be done with a finite amount of energy, which can be explained in the book of special relativity.

2.Theoretically, after the expansion of our space, there could be another universe that is geometrically symmetrical to ours, but it seems unlikely that anyone or matter will be able to reach that universe (limited by the speed of light) at the moment

3.I don't seem to have heard of any cosmic almanacs, but it is true that the distant galaxies we see through the telescope are just what they used to be, which means that we look not only at the distance through the telescope, but also at the history.

4.Parallel universes and our universe are generally not connected, and the two universes do not communicate with each other, so they cannot know the material situation in them. Moreover, there is no rational explanation for the distribution of positive and antimatter in our universe.

5.People looking in the mirror are just optical imaging principles, all in the same space.

6.The gravitational pull of the Earth is not enough to produce an interface with enough time stagnation, and there is indeed such an effect on the surface of the black hole, which we cannot get close to at the moment, and the properties around it are only speculation.

7.Magnetic fields exist everywhere in space, and there is no such thing as collisions. If it refers to magnets, it can only be attributed to the collision of atoms and molecules, but it has nothing to do with time and space.

8.Aether is only what was once thought to be a medium for the propagation of light, and it has been experimentally proven to be non-existent.

9.Now we think that if there were multiple universes, they should be unrelated to each other, and as for what to call them, there seems to be no special relationship.

10.The concept of time travel creates problems of causality, which is a basis in our knowledge system, and it is impossible to achieve it purely as time travel in science fiction. But it is true that in some extreme cases, such as the early universe or the interior of black and white holes, there may be extreme curvature of space, but these ideas are still theoretically hypothetical and far from true time travel.

I think you should have read a lot of books written by Hawking, and I am glad that you can think about and ask many questions, but many questions are not as simple as common sense seems, and they still require a lot of knowledge, and I hope that you can use your own knowledge to try to answer these questions in the future :)

The first question, the common people don't understand! I can only understand a little! Can't!

The second question is that the common people don't understand it even more!

The third problem is to use time to calculate space, first of all, this calculation is not right!

The fourth question, it should be, right?!

The fifth question, I don't think count! Since it is an imaginary image, how can it be counted?

The sixth question, please don't be so curious, have you heard of "Curiosity Kills Cats"?

The seventh question will only be known if there is a collision1

The eighth question is just like a child growing up, just eat!

The ninth question, something extracosmic? It's probably still the universe, right?

Question 10, please stop torturing us!

Then an electric charge passes through the center of an energized solenoid at a velocity of v0.

The speed after coming out should be faster than v0.

This one is wrong. The speed of coming out is still v0....The following is based on this. Alas. They all fell by mistake.

You can be a physicist in the future, at least I won't, but hopefully you can give an answer in the future, and it's best to create a time machine...

What is absurdity? It's ridiculous to do the same thing the same way over and over again, but expect different results. A person will only use such a single method as dieting every time, and then expect a slim waist, long legs, and hips, which is ridiculous.

In business, it is also ridiculous to always use traditional thinking to do new business and hope for quick success.

In the past, in a stable society and an era of slow development, as long as a person's way of survival was chosen, there was basically a fixed template, which could be copied and pasted directly, such as the farmers and industrialists in the agrarian society. But now is an era of rapid change and even turmoil, stability is no longer stable, change is the main theme.

The world is changing, so we must also solve problems in a dynamic way, and there can be no one-size-fits-all solution. If the goal is determined, then there are always more solutions than problems, but it is not easy to find a suitable solution and an optimal path. For example, from Beijing to Shanghai, the departure and destination are determined; Then there are many route options, planes, trains, high-speed trains, buses, self-driving, and even cycling, and different ways naturally take different time and energy.

It's getting more and more ridiculous to want to do different things in the same way, but to achieve the desired results. The traditional path is safe, the traditional method is skillful, but the new business is unprecedented, and it is bound to require us to use unprecedented methods; Lazy thinking can't replace the diligent pace, on the contrary, it just does a lot of hard work. This requires us to have a high level of mind and experience, and we also need to take the initiative to explore ourselves, or through the guidance of others, or inadvertent sparks of thinking.

We need to be full of imagination and creativity, but not alone at home reverie, or blind imagination.

For example, dieting is a self-deception. But in fact, exercise is also a difficult method, in fact, exercise is not about hard perseverance, but about establishing a person's lifestyle and habits. What is the purpose of a person's exercise?

The aim is for us to have a healthy lifestyle and a group of like-minded friends. If you discover your self-drive and change your thinking, then the basic movements will not be so hard. Is the goal of learning English to memorize 5,000 words?

No. It is so that we can read English texts and communicate effectively with others in English. If a person just lifts dumbbells hard, then he will soon be unable to persevere; If you just memorize words, you won't be able to communicate in English.

Self-motivation, purpose, way of thinking, and way of doing things are all things that we should consider in advance when we do things; Then go step by step to verify, adjust the method in time, instead of just using the method all the time to achieve the goal, after all, practice makes true knowledge. I hope we don't be so ridiculous anymore, encourage each other!
