Chapter 454: The Practical Value of Dyson Spheres

Obviously, it is not the stars themselves that can cause such a large change in the light curve, Jupiter is the maximum size that a planet can reach, but Jupiter can only block 1% of the sun's light.

Obviously, whatever obscures the star, it's huge, half as bright as the star itself.

Some scientists have put forward a very shocking hypothesis: we have seen a higher alien civilization building a Dyson sphere.

In fact, for human beings, there is only a relative lack of resources and space, and a huge amount of human resources are wasted on mutual prevention and confrontation.

If human beings settle down in their own swaddling clothes, the earth, they will face only one result - destruction.

On the day of the natural disaster, just because of a meteorite, our human civilization was almost wiped out of this universe, and two monsters could easily destroy a super metropolis.

It's just a corner of the country, and if we don't unite, extinction is only a matter of time.

Therefore, only by uniting and expeditioning to the stars and seas can mankind have a bright future.

For human beings, the universe is vast, and the resources are almost infinite.

.......

At this time, netizens all over the world have expressed their opinions on the Internet.

"Hehe, there is technology that can build Dyson balls, so you don't need such a thing as a Dyson ball."

"I'm on the same page as the one upstairs, it's like human nuclear fusion, you can make a small artificial sun, why make a Dyson sphere? It is even unknown whether antimatter will be used as an energy source in the future. ”

"With the technology to build a Dyson sphere, there is no need to use the Dyson sphere to harvest the energy of stars, and the construction of a Dyson sphere must be complete control of controlled nuclear fusion.

And not afraid of the high temperature on the surface of the star, then isn't it much more efficient to go directly to the star to mine mass matter than a Dyson sphere? ”

"The Dyson sphere is just a metaphor, not really building something that wraps around the stars, it's just an idea imagined in the barren and eclectic of our imaginations, maybe in fact it is mining stellar matter instead of making a ball? Who can say for sure what the future holds? ”

"But have you ever thought upstairs that if you want to build a Dyson sphere, in terms of the sun, you can't make a Dyson sphere by consuming all the material in the entire solar system except the sun, and the civilization that can build the Dyson sphere can at least directly mine the energy of the stars, why build a Dyson sphere?"

"Instead of sticking to the surface of the star to absorb energy, aren't the solar panels in life now not afraid of the energy on the surface of the star? In real life, we're already using the energy of the stars.

In the future, it is just that more efforts will be made to develop stars, such as sending a few solar satellites around the sun to make Dyson satellites, after all, no matter how advanced the technology is, it is impossible to reach the surface of the star. ”

And the Dyson sphere is nothing more than sending countless solar satellites together, leaving no trace of sunlight, floating in the air around the sun, maximizing the collection of solar energy and transmitting it to the earth as an energy source.

It is only sunlight energy that is being developed, not directly collected on the surface, which has been possible so far. "I love Chinese.com

"Yes, what is the purpose of our country's Three Gorges Power Station? It is already possible to build small hydroelectric power, thermal power generation, and wind power generation, so why spend so much energy to build the Three Gorges? Because once it's done, energy becomes cheaper, and the same goes for Dyson spheres. ”

"Upstairs, although I also disagree with the man's statement that 'you don't need to build a Dyson ball if you have the ability to build a Dyson ball', but the Dyson ball really can't be made from solar satellites alone.

The solar wind of the stars will blow thin satellites out of the star system, and if you use propulsion devices to fight it, how much energy will be output in the end?

So it has to, it has to be a ring structure, the strength of the material must be able to resist the interaction forces that can easily tear the planet apart, and the raw material should also be limited, so that person will have this idea that the Dyson ball is chicken ribs. ”

"Don't argue, what Dyson ball is not Dyson ball, what you see on Earth is also what was before 1840, and we will never see the real situation, not to mention,

What's the point of what we see? Now that mankind has experienced a catastrophe such as the Day of the Natural Disaster, it still has not been able to form a complete federation, and it is still like a plate of scattered sand in the infighting, so how can it get out of the earth and into the universe? ”

"Hehe, to be honest, don't talk about the Dyson sphere for so long, in terms of the energy industry, there are rumors that Datang Technology has mastered nuclear fusion technology, but Datang Technology has so far,

has not officially acknowledged this news, so it is very likely that Datang Technology has also been brought to the rhythm, and now the day when mankind will master nuclear fusion is still far away.

To be honest, if human beings do not use energy in a way that is separated from boiling water, it is very likely that controlled nuclear fusion will not be achieved.

It's the recent nuclear fusion experiment on Amejian's side, and there has been the latest progress, that is, the simple output energy is already greater than the input energy, but after boiling water, it is less than the input. ”

"You're too pessimistic, aren't you? How can you innovate without savings? Mankind has been completely stagnant in the field of basic science for 60 years, and until now mankind has been perfecting the theory of relativity.

In other words, for the 300-year scientific and technological explosion of mankind, human beings have been preparing for 100,000 years, so how many years of reserves do human beings need to make before the next scientific and technological explosion? ”

"Alas, let me tell you a more pessimistic fact, now there is no unified alliance of mankind to advance and retreat together, and the greatest possibility is before the next big bang of productivity,

Human beings have exhausted their resources, and the United Nations once made a statistic that more than 95% of the research conducted by human beings is repetitive research.

Because of the technical barriers between patents and countries and companies, and repeated research for many times, the more high-tech it is, the more likely it is to cause serious waste. ”

"It is said that because the sun has entered an active period, it may take less than 200 years for the equatorial surface temperature to rise to 70 degrees, Hawking once said,

Whether human beings can complete interstellar migration within two hundred years determines whether human civilization can continue to exist. ”

"No, didn't Datang Technology already say that it was going to develop environmental modification on Mars?"

"Don't listen to Datang Technology blowing water and transform Mars? What are you kidding, the earth has not been transformed, what are they using to transform Mars,

You asked Amejian's top scientists to come, they didn't dare to pat their chests and promise that they would be able to transform Mars, and you didn't even believe the words of scientists, but you wanted to believe the words of a businessman? ”
