If a spaceship of 1 second and 1 light year is developed, can human beings reach the end of the universe? The answer is disappointing

We have always had a goal, that is, to travel the entire universe. Although we are only a small species on the earth, after so many years of development, the rise of technology has given mankind the greatest confidence. Since we were children, we have liked to look up at the stars, looking at the starlight emanating hundreds of thousands of light-years away, we have set a goal in our hearts, to go to the sea of ​​stars in the future.

However, the ideal is very romantic, but the reality is very cruel. According to the current scientific and technological understanding of mankind, the speed of light is a limit of our three-dimensional universe, but from the scope of the universe we currently know, the universe is known to have 92 billion lights. year size. It takes 92 billion years to travel at the speed of light, which is a time point that no civilization on earth can reach in its lifetime. What’s more, it is sad that the largest powered spacecraft of human beings can only reach a dozen percent of the speed of light.

Faced with this cruel reality, human beings can only look to the future technological explosion to achieve this goal. Someone raised a question not long ago. If humans can create a spaceship that is one light-year per second in the future, with such a terrifying extreme speed, can we travel the universe to the end of the universe?

When we hear this option, we will definitely feel that it is a bit beyond the standard, because 1 light-year per second is countless times stronger than the speed of light, and even reaches the speed of the high-dimensional universe. No matter how large the scope of the universe is, it is only 92 billion light-years in size. With the ultra-high speed of walking one light-year in one second, we only need 920 seconds to travel the entire universe and reach the end of the universe. . But is this really the case? The answer may disappoint us.

First of all, the size of 92 billion light-years is just a maximum range deduced by human detection of various cosmic radiation, and it is a limit speculation that human beings can feel. You must know that human technology is still so small, and it is not enough to see in front of the universe. The range we speculate is called the visible field. With that kind of limit speed, we can only explore our limit perception field at the fastest speed.

But let's not forget that the universe itself is a concept of nothingness. Since the beginning of the big bang, the way humans understand it is still in a vague state. The time, space, and gravity we perceive are all just a sign of what humans have defined in order to better understand the universe. Strictly speaking, there is no scale problem in the universe, nor does it exist in terms of time and space.

If according to the statement in the film and television works of Men in Black, the size of the universe is the largest and smallest, and the smallest is also the largest. No one can approach an unreachable distance, and as long as the ability is achieved, any distance between the universes is just a distance. Instant things. Therefore, the speed of light itself is a concept of nothingness in front of the universe. It is only defined by human beings, and has nothing to do with the size and distance of the universe.

Another fact that cannot be ignored is that since the Big Bang, the universe has been in an open state. Even now, we are still in the aftermath of the Big Bang. It is expanding infinitely, and it is said that the speed of expansion is is to far exceed the speed of light. The universe has been running for 13.8 billion years since the very beginning. Even if we use the ultimate power beyond the speed of light, it is difficult to catch up with the speed of its spread. The speed of 1 second and one light year is not enough to see.

Therefore, it is not enough to talk about speed and scale in front of the universe. Only when human beings can evolve to a higher dimension one day, when we no longer regard time and space as an indispensable part of human beings Only at the cognitive scale can we truly reach the end of the universe.
