What is the future?

Just since the middle of the last century, when humans used solid-propellant rockets to put satellites into Earth orbit, the future has been placed in front of the world!

The future does not belong to the ground, the future belongs to the stars! The hope and journey of mankind will always be only the sea of stars!

The earth is a cage, and everything that seems beautiful in front of us is actually a mortal place. At any hint of wind and grass, human civilization will hover on the brink of survival and destruction.

The more connected the world is, the more obvious the signs become.

More than half a century later, the deeper we understand the starry sky and the universe, the more timid and fearful human beings become, and even more despair continues to sprout.

The starry sky that seems to be beautiful and seems to have infinite possibilities, leaving only unattainable despair for human beings on the earth!

When people learned to use fire, coal, oil, and electricity on the ground, they discovered the secrets of atomic energy, explored the threshold of nuclear fusion, spied on the mysteries of the quantum realm, invented the Internet to unite the world as a whole, and sent satellites to planetary orbits and humans to the moon. Even ready to explore Mars.

On the surface. Human beings are thriving in the exploration of the road of science and technology. Vibrant and ever-changing, it seems that it will not be long before human footprints will be able to set foot in the solar system, and soon even the universe will be surrendered to the feet of the earth's civilization.

Unfortunately, in fact - the more technology advances, the more fear people have! And this kind of fear is nothing for ordinary people who work all day long to make a living and have no time to think, but for scientists who really explore the forefront of science and technology, it is a real nightmare!

Not long ago, there was a lament that physics is dead. Today's physical theories have developed to the point that ordinary people can't understand them, and they are almost incomprehensible, abstract as if they were all kinds of supernatural events, like fantasy novels written by novelists.

People look at the cosmic black hole, only to find that the thing can only be seen, and it is a dream to try to use it.

People look at Earth-like planets thousands of light-years away, only to find that they can only look at it, and it is a dream to get there.

People are staring at things like interstellar travel, hoping that there will be a hole in the universe that can throw people tens of thousands of light-years away, and then how to get back becomes a problem...... And then. Everything can only be thought of, and the real practical value is almost equal to zero. Still dreaming.

And the most realistic problem is that people can still only use solid propellant weighing hundreds of tons to send an airplane-sized aircraft and a few people or monkeys and other animals into low-earth orbit, circle a few times and then fall back, or keep creating garbage into space, so that the earth is covered with man-made space junk, which is becoming more and more dense over time, and artificially weaving a very vivid and realistic debris garbage cage for themselves. (Space junk is increasing, and human space exploration will become more and more dangerous in the future.)

In the end, helplessness, sighing, despair.

And the greatest despair has been laid out in front of people - the speed of light!

Light is the limit of the speed of the universe. As long as there is matter in the universe, nothing can break through the limit of the speed of light. This is the iron law of the universe, fundamental.

The limit of the speed of light is 300,000 kilometers per second, and the so-called superluminal speed will actually only exist in theory forever, and cannot exist in reality.

And the vastness of the starry sky universe above us is a distance that is helpless even at the speed of light! Our image is given a simple and majestic name - light years.

It's just a light year, and even the light has to run for a year.

And where can the universe run in a year? The universe is an ultra-macroscopic scale measured in thousands, thousands, hundreds of thousands, millions, millions, billions, tens of billions of light years.

Human beings, who only have a lifespan of a few decades and a history of millions of years, are so small in front of the universe that they are not as small as a snap of a finger, even if they have the technological means to reach the speed of light?

What is even more outrageous is that in the great physicist Albert Einstein's theory of the world, the speed of light has a theory of relativity with time.

The closer an object moves to the speed of light, the slower the passage of time around it, and if the speed of light is exceeded, the time will be reversed.

This means a ridiculous reality, if humans actually invented a spaceship that could reach the speed of light and explore distant alien planets. It is assumed that the target planet is Earth 2.0, the planet that has been most closely resembled to Earth recently discovered. (NASA named 'Kepler 452b', a real planet, and some time ago it caused a news effect.) ）

Earth Two is 1,400 light-years away from Earth One and is located in the constellation Cygnus. The volume is 1.6 times that of the Earth, and the similarity of the planets is 0.98.

It is assumed that humans on Earth have mastered the technology to travel at the speed of light. Get ready to explore Earth Two. Space explorers full of hope have finally set off, and they are full of hope to go to Nova to spread the fire of civilization on Earth.

The people on the spaceship felt that time had not passed much, and they arrived quickly, and they were extremely excited.

But just because they don't feel the passage of time doesn't mean that the people watching over Earth don't feel it!

This time, three thousand years have passed, and when the great explorers returned, they found that the earth had long been destroyed, the country had become a joke, and human civilization might have disappeared into cosmic dust......

And what did they become as explorers in the end? A wanderer of the universe? Or is it the spreader of the spark of the earth's civilization? Or is it just a group of time travelers who sail at the speed of light and face the rapid passage of time and witness the destruction of the universe in their lifetimes?

So what is the point of their exploration of the universe?

The end result is that it's pointless!

The only thing that can be witnessed is a sad song of the end of life!

(Non-stop travel at the speed of light, the passage of eons of time outside may not be a few years for a light-speed navigator, but at this time the universe may have passed tens of billions of years and is on the verge of death.) The final ending of Da Liu's sci-fi "Three-Body Problem" is so full of sadness, everything is destroyed at the speed of light, including the whole universe. And then eventually, all I saw was deep despair. ）

And such an iron law, despair, is not only for the human beings on earth, but is binding on all civilizations in the entire universe, including the alien civilization that we have been fantasizing about!

They also have to face the desperate limit of the speed of light!

This may be the fundamental reason why we still haven't seen aliens until now. It's not that aliens are not technologically advanced enough, but no matter what, they will eventually be unable to break through the limit of the speed of light, reach other galaxies, and never see human civilization on other planets.

It's close at hand, but it's far away from the world, and it's unattainable.

(Note: Actually, I think that the meeting between two different planetary civilizations in the universe is almost impossible because of the existence of the limit of the speed of light.) Of course, writing a book is another matter, and I would break through the speed of light limit with another theory. ）

……

And at this moment, the deputies of the countries who are squabbling in this UN Security Council obviously see some kind of hope!

Because they've been sure that aliens have fallen to Earth!

What does this mean?

In the eyes of these bigwigs, who spend their days thinking about the international strategic situation, they don't care at all whether a person has the consequences of those more entertaining superpowers!

In their eyes, as long as those superpowers can still kill to death, and the existing weapons can still work, they are not an existence that cannot be dealt with. At most, the consequence is to kill more people, and they don't think that a nuclear submarine can destroy the world, that's just a naïve idea, if you take precautions in advance, the five hooligans of the United Nations are not stupid enough to strike back as soon as they are attacked, and everyone will not be stupid enough to dump all the nuclear arsenals out, and strategic defense and missile systems such as NMB and TMB can still play a certain role.

On the contrary, it is the hidden future interests of this alien that are truly unfathomable!

The appearance of aliens means that the civilization represented by this alien has the ability to cross the sea of stars! Possess the ability to cross the sea of stars and reach alien planets within a reasonable, possible, and meaningful framework!

And whoever has the advantage in this point will hold the real future!

If any country can really cross the sea of stars and reach the alien planet in a short period of time, who cares about the small land, small land, and small island on the earth?

What they have is a whole planet!

No, not a planet!

The sky is full of many planets, and even stars, will become an endless source of resources, enough for every citizen to squander to the point of endless, and truly realize the perfect world of distribution according to demand written by Marxist-Leninist, so that the civilization of their own country can become the surmount, pinnacle, and symbol of the earth's civilization, and survive in this universe forever...... Until 10,000,000 years. (To be continued......)
