What happens after humans travel faster than the speed of light?

The speed of light is the fastest speed known to date.

The laws of physics tell us that the speed of any object with rest mass in the universe can only ever approach infinitely close to the speed of light , but it can never equal or exceed the speed of light.

This is because as an object's speed gets closer to the speed of light, its mass gets larger and larger and requires more and more energy, eventually reaching infinity. This is the relativistic mass-energy equation , which tells us that mass and energy are equivalent, and the speed of light is the conversion factor between them.

 The speed of everything in the universe is only close to the speed of light. (Illustration).

So, for an object to reach the speed of light, it would require infinite energy, which is impossible . But what if we assume that humans could travel faster than the speed of light? This is a very interesting and controversial topic, and scientists and science fiction writers have made various guesses and assumptions about it.

The universe is a vast and mysterious place, containing tens of thousands of galaxies, each galaxy containing billions of stars and planets, some of which may be suitable for life. According to small probability events, with the support of a huge number of humans in the universe, it is very possible that there will be civilizations more advanced than human civilization, they may have mastered superluminal technology and can freely travel and explore the universe, or they may have discovered the existence of humans, but for some reason have not been able to contact us.

If humans can also exceed the speed of light, humans will be able to travel between stars and make contact with higher cosmic civilizations , thereby gaining unprecedented knowledge, technology and wisdom, allowing human civilization to develop and improve further. Of course, this is also a double-edged sword, because we cannot predict the purpose and attitude of alien civilizations, they can be friendly or hostile.

When human speed exceeds the speed of light, light will change from virtual to real. (Illustration photo).

If we can meet friendly advanced civilizations, human civilization can develop further and learn from their technology and culture. We can establish friendly relations with them and explore the mysteries of the universe together, which will be the greatest leap forward in human history.

However, if we encounter a hostile advanced civilization, human civilization may be destroyed, considered inferior, enslaved, or even eliminated. The universe is also the law of the jungle and survival of the fittest, advanced civilizations may invade, plunder, or experiment with lower civilizations.

This would be the worst nightmare in human history. So if we want to surpass the speed of light, we must be fully prepared to improve not only our technological level but also our moral level.

When the speed of human exceeds the speed of light, the light will change from virtual to real. The light around us will gradually change from virtual images to physical images, the content of the photos are the events we have experienced in the past.

This is because light is an electromagnetic wave and takes a certain amount of time to travel through space. When we see stars in the sky, we see them as they were before, because the light they emitted took millions, even billions of years to reach our eyes.

Even if the speed exceeds the speed of light, we cannot change the past. (Illustration photo).

Similarly, when we see objects around us, we see them as they were in the past, but the time interval is too short to be ignored. But when our speed exceeds the speed of light, we will catch up with the speed of light, even surpass the speed of light, so that we will see the history of light, which is our history . We are like people watching a time movie, silently watching our past on the 'screen'.

This sounds interesting and exciting, because we can meet again some people and things that we have forgotten or missed, maybe our childhood, maybe our lover, maybe our regrets. We can get a little happiness, a little touching and a little enlightenment from it. But we cannot change the past.

The past is the past, and no matter how hard we try, we cannot change the course of events . The order of time and space in the universe does not allow anyone to arbitrarily disturb the past or the future, the past has become history and is recorded by time and space.

If we try to change the past, we may cause some paradoxes, such as the grandfather paradox. This leads to an endless loop and self-contradiction. Therefore, trying to change the past or see into the future by traveling through time is not practical.

The space we humans are in now is a three-dimensional space, we can feel the length, width and height, these three directions form our spatial coordinate system. However, we cannot perceive time, for us, time is a one-way flow, we can only move from the past to the future but cannot reverse or stop.

However, physicists believe that time is actually the fourth dimension of space , creating four-dimensional space-time , and we simply cannot observe it directly due to our limited cognitive abilities.

Currently there is no experiment that can prove that humans can surpass the speed of light. (Illustration photo).

If humans surpass the speed of light, they will most likely enter the four-dimensional space-time, in which humans will not be bound by time, this is a completely new realm for humans, and we can freely choose where we want to go, whether it is a moment in the past, a moment in the future, or a parallel moment. We can freely explore different timelines, see different possibilities, and experience different lives.

Time is no longer so important to humans, we can swim in the long river of time and enjoy the beauty of time, we can also choose between the forks of time and create the magic of time. At the same time, humans can reach the level of mythology, because we can control time, even create time, can become the master of time and the creator of time.

Of course, these results are based on some theories and assumptions, currently there is no experiment or evidence that can prove that humans can exceed the speed of light or what will happen after exceeding the speed of light.

These are all our imaginations and speculations, and maybe one day we will be able to test these ideas, maybe never. However, this does not stop us from exploring and thinking about this topic, because this is the embodiment of human curiosity and creativity, and at the same time it is the driving force for human progress and development.
