Do you think humans can exceed the speed of light and travel into the future?

People seem to be able to exceed the speed of light, just like Brother Monkey. Although he is not a human, he is a monkey, but in terms of exceeding the speed of light, there is no difference between humans and monkeys, and Brother Monkey’s speed is not very different from the speed of light. , think about whether the Great Sage has traveled through time and is now with us.

It’s not necessarily possible to reach the future by exceeding the speed of light. How can you reach something that hasn’t happened in the future yet? Besides, you are running so fast beyond the speed of light. What should you do if you accidentally hit a meteorite? Traffic accidents can easily occur if the wiring is wrong in space.

Why don’t you just fly around like a fool and whizz into a black hole, and still want to reach the future, you can make its snacks in the black hole, and there are white holes, and you can fly faster than Even if the speed of light is faster, it can blow you up.

So no matter how fast you fly, you have to be careful. Now I have thought of a good way to reach the future. I want to find a way to live longer, or freeze myself. If you don’t think these two tricks are good enough, I’ll teach you. If you are lucky, buy a moonlight treasure box, wait for the full moon night, pineapple and jackfruit, and swipe it. Five hundred years from now, how many generations of your grandchildren will be eating, and you will see the genealogy of his family that records you. When did it disappear. But he definitely doesn’t believe you and believes you are a ghost.

Is it necessary to go to any future? Even if the technology is very advanced in the future, you can go there, but the tickets are expensive, and the tickets to the future are even more expensive. Even Jack Ma has a pain in buying them, so save it. Well, don't travel to a primitive forest in the future. As soon as you appear, a tiger will come and look at you. It will pounce on you and bite you. How about traveling to a battlefield and you appear in space? , a bomb explodes next to you, and you're done playing again.

So traveling through the future is a high-investment and high-risk project, just to create curiosity about the future. I feel like it’s not worth it.

I saw a group of big guys trolling the questioner. In fact, I want to say that if a person has no dreams, what is the difference between him and a salted fish? The purpose of the question subject is to transcend time and advance into the future. Faster-than-light flight is just a means that he thinks can realize his wish. Therefore, let me give the conclusion first. There is no problem in traveling to the future of 2030! But don’t just pick FTL.

Since the establishment of Einstein’s theory of relativity, space and time have been liberated from absolute space and time under the premise that the speed of light remains unchanged. Especially time, each person's time dimension can exist independently without belonging to the only time dimension of the universe. So in principle, time for each of us exists independently, and traveling to the future has a theoretical basis.

Time transcendence is theoretically possible, but it does not mean that you can set off immediately, open any door, and use time machines to walk around the streets. I am serious about popularizing science, and of course I have to base it on theoretical foundations.

First of all, the first move through time travel is to stop your own time! You are a superman and can stop the earth, but we are not, so we have no choice but to choose cryogenic hibernation. It seems that the most cutting-edge human body refrigeration technology already exists, but just freeze it and don’t wake it up! Many terminally ill patients and people with financial freedom will know some common sense. But if you are just curious and want to travel, I don’t recommend you to take the risk.

The second move through time travel, speed up, and surpass other people’s time! This is the direct application law of relativity.

Theoretically, if you reach a speed close to six decimal places of the speed of light, you can make a round trip to Proxima Centauri. The subject will spend less than 10 hours on the spacecraft and return to Earth in exactly 2030! It's time to travel through the future. But, where can I find a light speed spaceship? This is not a question I should think about. I suggest you pay more attention to scientific experiment recruitment advertisements.

Actually, living every day well in the present is the right path. If you don’t succeed today, wouldn’t it be even worse if you go to the future?

I am Mr. Cat, thank you for reading.

Let’s not ask whether super-light speed is possible. Since the fastest propagation speed of all forces between materials in this universe is the speed of light, all matter and energy in the universe cannot sense each other’s existence fast. Compared with the speed of light, if there is super-light material, it will not be perceptible in this universe, which means that this material has disappeared in this universe. Therefore, super-light material does not exist in this universe and does not belong to this universe. Therefore, faster-than-light travel cannot travel to the same time point in the universe, but can only travel to a time point in another universe.

Traveling to the future is actually time travel, and does not require faster than light speed. As long as it flies infinitely close to the speed of light, according to Einstein's special theory of relativity, if humans use a certain flight tool to fly at 0.99999 times the speed of light for 18 days, it will be equivalent to 11 years of time on the earth. At this time, it will be 2030 when we return to the earth. .

Currently, super-light speed appears in two fields. One is the Star Trek series, which spans decades! The third part we watched two years ago was actually the thirteenth part, which was not just about super-light speed, but about warp sailing three times/seven times the speed of light!

To put it simply, it means compressing the space in front of the spacecraft. The space becomes smaller, and the distance of course becomes closer. The sailing speed is normal and will not affect the human skeleton! Unlike the voyage in "The Three-Body Problem", you must first fill the interior of the spacecraft with bubbles while sailing at high speed!

For example, if I drive a spaceship from Beijing to New York, the speed is still 1,000 kilometers per hour, but I compress time and space and compress the space between the two places. It can be compressed to three times the distance between Beijing and Hawaii, or it can be compressed to Of course, the five times the distance between Beijing and Seoul can be reduced to seven times the distance between Beijing and Tianjin. This allows us to reach our destination quickly, which is really convenient for interstellar navigation!

The above data estimates are very demanding for the power of the spacecraft, and it will be difficult to achieve within hundreds of years! But I don’t know what will happen in the next thousand years, but the movie describes that once controllable nuclear fusion technology is available, it will not be far away! As for whether to travel to the future of 2030 or the past of 1990, it is easy!

The other is that the Copenhaar faction, headed by Einstein, a representative of classical physics, and Bohr, a representative of quantum mechanics, encountered irreconcilable contradictions when they argued about the properties and trajectories of particles!

Classical physics believes that there is a causal relationship between the movement of matter. Once the initial state of an object is determined, its trajectory can be determined. There seems to be nothing wrong with this. In our lives and in the star system in the universe, even if something unexpected happens We can also calculate the future trajectory of extraterrestrial asteroids to deduce the probability of them hitting the earth, such as the nearest Tianya Haijiao, Oumuamua, Bennu, etc.!

But returning to the microscopic world, everything seems to be uncertain. Quantum operation is no longer a traceable track, but a ghostly transmission at super-light speed! Especially the phenomenon of quantum entanglement. Two entangled quanta, no matter how far apart they are, can always move on one side and the other side moves in step at the same time!

The final explanation is that it is an instant collapse state, like Schr?dinger’s cat! When no one is observing, the cat is in a quantum superposition state of life and death. Once someone opens the device to observe, the cat immediately collapses into an entity state of either dead or alive. This uncertainty is the essence of quantum theory! Until now, scientists have developed a quantum computing model, but it has not yet been launched!

As for whether the quantum phenomenon collapses instantaneously or because it runs so fast that we cannot observe its trajectory? It is still being explored. At least according to the current technological level, the electronic trajectory can only be considered to collapse in an instant!

Super-light events have occurred in the above two fields. Perhaps we will wait until we build a larger collider in the future to see if we can explain the super-light phenomenon! If it is discovered in the future that electrons move in a trajectory, then we will be one step closer to the essence!

Super-light speed is not allowed to exist in theory, and the so-called super-light speed to achieve time and space travel is even more random.

The accurate definition of the speed of light in Einstein’s special theory of relativity is:

According to Einstein’s special theory of relativity, time is no longer absolute, and the speed of an object will affect the object itself The speed at which time passes is the time dilation effect that everyone often hears about. The faster the movement speed, the slower time passes, until the speed is infinitely close to the speed of light and time is infinitely close to standstill.

Einstein’s time dilation effect theory is sufficient when the speed is infinitely close to the speed of light. However, some people have concluded that time dilation has continued: when the speed is equal to the speed of light, time stops, and when the speed exceeds Time travels at the speed of light.

But in fact, this statement is incorrect. The subsequent conclusion that objects cannot reach the speed of light naturally does not exist. Therefore, there is no necessary connection between time travel and the speed of light.

At present, the theoretically supported space-time travel is the "Einstein Rosen Ring", which is a special solution to the field equations of general relativity, which is also the wormhole that everyone often sees in science fiction works. The core of general relativity is "space-time curvature". If space-time is curved, then there may be two locations at different times and different places because the space-time curve is connected together, and passing through this node means traveling through time and space.

However, we have not found wormholes so far, and it is unknown whether they really exist in the universe, but at least this is a hope for human beings to achieve interstellar navigation in the future.

If humans want to exceed the speed of light, it is completely impossible based on the current orientation of thinking. Similarly, if you want to travel to the future, no matter how you imagine it, how can you enter other universe dimensions? , this is absolutely impossible.

Everyone should know that the speed of light is considered to be the fastest speed in the current universe, and the fastest speeds in the universe are also radio waves and gravitational waves. In the universe, there are at least three, or even more than three, types of waves with the fastest speeds in the universe. What does this characteristic of the universe hint to us? You might say that the maximum speed of the universe has been limited by some advanced intelligent force. Only if the fastest speed in the universe is limited to a value, then the development of the universe will be orderly, and will it be different from what it is today, which makes it impossible for us to imagine the infinite size of the universe. As for these more distant fantasies, we won’t talk about them here. Let’s just talk about the speed of light for the time being.

In fact, for light, electricity, gravitational waves and other existences without mass, they can reach the speed of light at the same time, without acceleration, and without any reason. This can only explain one point, that is The speed of light is a cosmological constant, not the speed we know in our daily lives.

The speed of light is a cosmological constant that can only be reached by particles without mass. This is also regarded as a universal rule. If humans want to reach or even exceed the speed of light, they must fundamentally carry a large amount of matter with them. Massive particles violate this rule. Obviously, this is fundamentally impossible.

So, to take a not very appropriate benchmarking example, absolute zero is a limit value that all operations in the universe cannot reach. Similarly, the speed of light is also a limit value, and everything in the universe It is impossible to reach a massed object through any operation.

The speed of light can reach, let alone surpass, this is actually generally recognized, but our understanding of it is limited to our current scientific understanding and our current universe dimension space, but if we What about setting aside current cognitive limitations? The speed of light cannot be exceeded. Is this an absolute? In order to answer the second small question, we can only assume that there will be a discovery breakthrough in the future, find the root of the existence of the speed of light constant, and then advance human civilization to level two or even level three. In this case, we There is reason to fantasize about the possibility of going to the future or going back to the past.

Traveling into the future, even if we can exceed the speed of light, can we really transcend the future? Or even go back to the meeting? This fantasy of time travel is perfect, but it’s actually impossible. Some people say that in the five-dimensional universe, the creatures inside can fiddle with the time dimension at will, and can easily go back to the past or to the future.

In fact, such a fantasy does not require any basis. As long as it can be imagined, it must be possible.

We can now assume that we are now in the five-dimensional space that people imagine. If we can easily go back to the past or travel through the future, that is to say, in that five-dimensional universe, The past, present, and future must exist at the same time, so how can these three time periods, past, present, and future, exist at the same time? Their simultaneous existence is a complete paradox of time. But if we analyze it based on science, that is, from the perspective of thermodynamics, many people will actually believe that time does not exist. The time we know is nothing more than a marking scale invented by humans to plan life in an orderly manner. Since time does not exist, then it does not matter the past, present, or future.

If there is no past, present, or future, the paradox of time will not exist. Then can we go back to the so-called past and go to the so-called future? The answer is obviously impossible, because if you want to go back to the past or the future, the thermal motion and spatial position of all substances except your body need to be returned to the past, or even to the future, which cannot be changed. state.

Therefore, if you want to go back to the past or go to the future, you must get rid of all the constant laws of the universe. If you can get rid of all the constant laws of the universe, it means that you are not the universe. If you don’t exist as a material object, you will not be able to participate in the material operation of this universe. Going back to the past or going to the future will be meaningless to you.

It’s impossible, you can go to other worlds. The world is composed of matter and energy transformation. Consciousness is also part of the energy transformation and can be seen as bioenergy, the energy of the nervous system. The world has a speed faster than the speed of light. We temporarily call it phantom speed. We can use this method to visit other worlds in a short time, provided that the energy consumed is also immeasurable. If the speed is not enough, it will take tens of millions of years to reach another living world. The average life span of a human being is only 80 years old. The energy of the earth is limited, and the energy of the entire solar system is also limited. Advancement is limited, so the chance of human beings going to other universes is zero.

The faster the speed, the greater the mass, and the greater the mass, the greater the gravity.

If the upper limit of the rules of the universe is the speed of light, then if one microgram of mass is accelerated to the speed of light, then at this speed, the mass of this microgram static mass of matter will also become infinite. At the same time, gravity It will also be infinite.

When gravity is infinite, it will actually be a universe-level destruction disaster.

Therefore, there are huge technical obstacles to achieving light speed flight, or even super-light speed flight. Because this itself is a paradox.

Therefore, in the past fifty or sixty years, discussions about space navigation have focused more on conjectures about wormholes, black holes, etc.

What is a wormhole? Are there really wormholes in the world?

Super-light speed is possible, but it’s a little far away. You need to reach the speed of light first and then go to super-light speed. As for traveling to the future, don't dream about it. What is the concept of traveling to the future? It's impossible. At most, it means traveling through space. Traveling through space does not mean traveling to the future without a watch, and it does not mean that you can go back to the past. What is the concept of traveling through the future? It is traveling through time and space, not a simple concept like traveling through space. You must know what it means to travel through space. Traveling through space is faster than the speed of light, which is less than the speed of light. Space travel will not be hindered by any material, just like the signal emitted by a broken phone. When a phone signal is emitted, there is no substantial material obstruction in space.
