Knights in the big world of American TV series

Barry looked at the father and daughter helplessly... He was used to it.

But others were fed up with it, especially Caitlin Snow and Cisco Ramone.

Katherine Snow was Harrison's most loyal assistant and his student. Tess had a good relationship with Snow in the past, and Snow's boyfriend was also a disciple of Harrison. Together they founded Star Laboratory.

However, in that heartbreaking experimental accident, his boyfriend Ronnie Raymond died, leaving no bones behind.

The explosion of the particle collider changed the fate of many people. Harrison's lower body was paralyzed, Ronnie died, and Snow gained superpowers in the accident. She became Killer Frost...

Well, this is a nickname she gave herself, but not many people know about it.

She didn't like this ability, which would remind her of bad memories during that explosion. Harrison, Snow and Ronnie were all at the center of the explosion. Harrison was injured immediately.

In a coma, Snow and Ronnie desperately tried to save their teacher by taking him into a safe facility... At the last moment, Ronnie pushed them both into a safe facility, and he was caught for the first time in Snow's eyes.

The power of the secondary explosion turned it directly into ashes...

So Snow hates his ability...

But I have to say, this ability is quite powerful.

Her new state is very basic, almost primitive. Her body is completely encased in frozen soil. She is not made of ice, but she produces organic ice-like cells that make up her altered genes

.She can generate ice spikes to pierce an opponent, kill an ordinary person with her icy kiss, and/or create an ice storm strong enough to freeze everything and kill multiple people.

At the same time, this ability is also very dangerous, and it can hurt other people if you are not careful.

She becomes a so-called "heat vampire" who must absorb heat on a regular basis in order to survive. The most effective way to satisfy this "hunger" is to absorb the body heat of others.

Although she also gained an effect similar to immortality... As long as she can absorb heat, she can recover even from fatal injuries.

In order to ensure that her ability does not harm others, she wears a suppressor that Harrison helped make. At the same time, she basically never leaves the laboratory. This will make her feel a little better. According to her, she can always feel Ronnie.

Still by his side...

She is the youngest and brightest scientist at S.T.A.R. Labs. She can solve puzzles in a day and can repair and operate heavy-duty generators

As for Cisco Ramon, this Mexican guy is undoubtedly lucky. This guy escaped because he was drunk and did not come to work on the day of the explosion.

But privately, this guy envied Barry and Snow... Although he never dared to say this in front of Snow. But he did envy Barry very much. He felt that his life was too boring. If he could become a superpower

Or, he can also become a superhero.

In fact, the current establishment of this team is also due to Sisko, who is the most active. If you can't be a superhero, then you can be the assistant of a superhero.

Like Robin next to Batman.

Sisko is a member of Central City's S.T.A.R.S interstellar laboratory and is Dr. Wilson's assistant. After Barry was struck by lightning, he and Caitlin stayed with him and were the first to discover Barry's physical abnormalities.

After learning that Barry had acquired the super power of extreme speed, he developed a red Flash suit. After that, when Barry encountered difficulties and needed help, Cisco and He were always by his side, providing Barry with tactical strategies and coping methods. In addition to threatening him,

Another "think tank" besides Dr. Charles.

These two people were the early veterans of Barry's team, and even Harrison was persuaded to join later. He didn't want to participate in this nonsense at first, and he was still immersed in the pain of failure.

At that time, he wanted to die. After all, his wife's inheritance had been destroyed, his students and many outstanding scientific workers had died, and he himself was paralyzed.

How could he have such thoughts!

Until Barry showed the powerful speed force.

This piqued Harrison's interest.

Because he had a conjecture, a conjecture that could save everything, which was to let Barry exercise the Speed ​​Force to achieve the purpose of reversing time and space.

According to Einstein's theory of relativity, when the speed of an object reaches the speed of light, space and time will lose their meaning and time will stop. So if the speed of an object exceeds the speed of light, does it mean that time can flow backwards? If this theory is established, then can humans

Can we go back to the past through time and space? Let’s listen to how scientists explain this. We know that according to Einstein’s theory of relativity, the speed limit of an object is the speed of light. When the speed of an object reaches

When reaching the speed of light, time and space will be meaningless and time will stop. No matter how the external time changes, the time of an object at the speed of light will be in a static state. For example, you take a spaceship and fly at the speed of light to 100

When a planet light years away reaches this planet, for people on earth, 100 years have passed, but for you, you will only feel that only a moment has passed, and you have not aged.

The time of an object flying at the speed of light itself is in a stationary state. Some people have imagined that does that mean that if we sit in an object flying at the speed of light, we can become immortal as long as we keep flying like this? There is another question.

, if the speed of light can make time stand still, then if the speed of an object exceeds the speed of light, can we turn back time and go back to the past?

In fact, this is obviously impossible. Just imagine, if flying at the speed of light can turn back time, is it because the spaceship flies at the speed of light? Not only will the people in the spacecraft not age, but they will also get older and older.

Young? In fact, this is simply impossible. Traveling through time and space and going back to the past may exist, but it is obviously not something that can be done simply by exceeding the speed of light. There is a concept of time in it. There are two kinds of things in the universe.

Two concepts are the most mysterious and difficult to understand. One is space and the other is time. Space is okay. Modern scientists are studying more and more and understanding more and more, but we know nothing about time. The time we understand is just

Time as defined by humans is not the essence of time at all. What is real time? There is no way to start. It is much more complicated than studying dark matter and dark energy.

Time is thousands of times more mysterious than space. What can you do if you master space? Mastering space can ignore the limitation of distance. The universe is vast. Without infinite speed, it is impossible for you to explore the entire universe. The speed of light in the universe is only

It can be regarded as the basic speed, and super-light speed is the king speed. So how to make the speed break through the speed of light and reach super-light speed? This requires the use of the concept of space. The universe looks very smooth and complete,

But if you zoom in on the universe, you will find that the universe is filled with many space cracks, and these space cracks are space channels. As long as you master the mystery of space, you can open the space channels in the universe at will, and the spacecraft can enter them.

Achieve faster-than-light flight. However, faster-than-light flight can only allow you to quickly reach the depths of the universe. It will not make you younger and younger, nor will it allow you to travel through time and space and go back to the past.

So is it impossible to travel through time and space? Of course not, if you can completely control time, you can do it by combining space and time. As we just said, flying faster than the speed of light can only allow you to travel quickly through the universe. This is just

Navigation over spatial distance, but if you want to go back in time, you must add the concept of time. Going back in time is an application of time, but time alone cannot travel through time and space, go back to the past, etc. You also need

It requires space to combine, which means exceeding the speed of light. Therefore, if you want to travel through time and space and go back to the past, you also need to open a time channel. The speed in this time channel exceeds the speed of light, but it does not allow you to travel to a certain place in the universe, but

It is an application that combines time, allowing you to sail in the long river of time. You can see the vicissitudes of history in this time channel, you can see the scenes of the past, and even see hundreds of millions of years ago, billions of years ago.

scene.

Many people may wonder, when will humans be able to master time and space? Then a time machine will be built and we can time travel. The idea is good, but it is not easy for humans to master time. They must fully master space.

At the rate of human development, it is conservatively estimated that super-light flight may not be realized for another 10,000 years. And time is tens of millions of times more complex than space, and it may take hundreds of millions or billions of years.

Harrison believed that the Speed ​​Force could achieve such an effect... although this idea was considered nonsense by Snow and Sisko.

But Harrison had his own theory.

In the long years of the universe, we humans have experienced the baptism of time. From infancy to old age, from morning sun to sunset, we are all experiencing the progress of time. What is strange is that time seems to only move towards the future.

The direction of development cannot be reversed. This phenomenon has not only caused philosophers throughout the ages to think hard, but also triggered scientists to explore the nature of time. We need to understand time

The essence of time. Time is a measure and the order in which objects move in space. According to Einstein's theory of relativity, time and space are related to each other and constitute an indivisible whole - space-time. Space-time was in the Big Bang in the universe.

Birth, passes with the expansion of the universe. The time we experience is actually the movement trajectory of objects in the four-dimensional space, from the past to the present and then to the future.

So, why can't time be reversed? This involves the law of cause and effect in physics. The law of cause and effect points out that events always have their causes, causes and consequences, and the forward movement of time is exactly in line with this law. We can imagine if time

If it can be reversed, then the law of cause and effect will no longer exist, and the occurrence of events will become disordered and unpredictable. Therefore, in order to ensure the stability and order of the universe, time can only develop in the direction of the future.

In addition, the one-way nature of time is also related to the principle of entropy increase. According to the second law of thermodynamics, in a closed system, entropy (that is, the degree of chaos or disorder of the system) is always increasing and cannot decrease on its own. This means

Therefore, the evolution of the system always proceeds in a more disorderly direction, and the forward movement of time is the embodiment of this process. Because the universe is a closed system, the one-way nature of time also conforms to the principle of entropy increase.

However, in the microscopic realm, time is not absolute. The double-slit experiment in quantum mechanics shows that the behavior of particles is uncertain, and the distinction between the past and the future becomes blurred. This shows that in the microscopic realm, the concept of time does not apply

.Scientists are working hard to explore the principles behind this phenomenon in order to reveal the mystery of time.

In addition to physical explanations, the one-way nature of time has also caused deep thought in philosophy. Since Augustine, many philosophers have thought about the issue of time. They believe that the passage of time is a feeling of the human mind and a human

The limitations of cognition are manifested in the perception of time. Since humans can only perceive part of the changes in the material world, the movement of the material world is summarized as the passage of time. This view believes that the one-way nature of time is an illusion of the human mind

, but in fact the passage of time is even and bidirectional.

Einstein's theory is based on the assumption that the speed of light is constant. He believed that the speed of light always remains constant no matter what inertial reference frame the observer is observing in. This triggers an interesting phenomenon when an object moves at a speed close to the speed of light.

time will slow down, and when an object exceeds the speed of light, time will slow down

Time will travel backwards. To better understand this concept, let us illustrate it with a simple example. Suppose you leave the earth in a super-light spacecraft and your friends stay on the earth. When you are far away from the earth, you

Your friends will see your time slow down as your speed picks up

Near the speed of light. And when you return to Earth, if your speed exceeds the speed of light, your friends may see you go back in time and you become younger. However, in practice, exceeding the speed of light is unachievable because

No matter can exceed the speed of light. However, scientists have

Observing extreme celestial bodies such as supernova explosions and black holes in the universe, some evidence supporting Einstein's theory has been found. The gravity in these celestial bodies can bend space and time, causing distortions of time and space. Observing these celestial bodies from the earth, we may see

They turn back time or slow down time.

Some experiments also proved Einstein's theory. For example, in 1971, scientists experimentally measured the expansion and contraction of time. They used the experimental method of flying an atomic clock in the air to measure the relationship between time and speed. Experimental results

Shows that when an object moves close to the speed of light, time will

Slowing down. However, Einstein's theory has also caused some controversy and refutation. Some physicists believe that the speed of light is the ultimate speed of the universe and cannot be exceeded. Furthermore, even if we can achieve speeds beyond the speed of light, according to Einstein

theory, we cannot see the past because time itself no longer exists.

In short, Harrison seems to feel that as long as Barry is fast enough, he can solve these problems!

Although no one knows where Harrison got his confidence.
