"How did you do that? It's incredible. Ji Ran looked at these nerves in surprise and looked a little abnormal, but the eldest sister who did have special functions asked.

"I have to ask the eighth child about this." At this time, the third sister put on a shower cap and turned to look at the eighth sister who was sitting on the opposite bed.

Ji Ran looked at the eighth sister, she was the youngest, and she looked like she was only fifteen or sixteen years old, why did she ask her?

"You don't know that, do you? Don't look at the young age of the eighth child, but she knows a lot of things, she cultivates immortals and enlightens all day long, and she is already half an immortal. The boss said suddenly, but her words made Ji Ran couldn't help but be shocked, and her eyes widened in astonishment, how did she know what she was thinking in her heart?

Looking at Ji Ran's confused look, the third sister smiled and patted her head: "The eldest sister can be psychic and can read people's minds, of course she knows what you are thinking." ”

Hearing the third sister's explanation, Ji Ran felt even more amazing, it seems that everyone in this room is not a simple character, but a person with great powers.

"Eighth child, come and tell you the fifth child." The eldest sister turned back and shouted to the bed opposite.

Hearing the call of the eldest sister, the eighth sister slowly opened her eyes, jumped from the bed, and jumped directly to Ji Ran's bed, but she was as light as a swallow, she didn't step on the bed board, and sat down opposite Ji Ran steadily.

"Fifth sister, what do you want to know?" The eighth sister looked at Ji Ran and asked.

"I wonder why you have special abilities? A lot of abilities are obviously contrary to today's science, isn't this scientific? Ji Ran asked strangely.

After all, Ji Ran was also from science and engineering before, and she received scientific education since she was a child, and she had a sense of rejection of feudal superstition and strange forces in her bones, but the special abilities of these magical sisters in front of her were obviously beyond the scope of science and beyond her imagination.

"Fifth sister, let me ask you a question." The eighth sister suddenly looked at Ji Ran and asked.

"You ask." Ji Ran said.

"How big do you think the world is? Is the Earth the center of the vast universe? Will human civilization be the only intelligent civilization that exists in the universe? The eighth sister's question stopped Ji Ran at once.

That's a bit too big, isn't it?

Even scientists can't be sure if there is an extraterrestrial civilization, how can Ji Ran know if there is?

However, Ji Ran has not thought about this problem, she has liked to read science fiction books since she was a child, likes to look at the stars in the sky, and is also obsessed with astronomy.

When she was in elementary school, she could skillfully recite hundreds of small galaxies in the Milky Way, she knew that the Milky Way alone was more than 100,000 light-years in diameter, and there were 100 billion stars, assuming that each star had ten moons, then there would be a trillion planets, and in this trillion planets, who could guarantee that there would be no terrestrial planets?

Assuming that there will be one terrestrial planet in one million planets, then there will be one million terrestrial planets in the Milky Way, and if only one of the 10,000 terrestrial planets will give birth to civilizations, then there will be at least 100 civilizations in the galaxy, and this is still the most conservative estimate.

The Milky Way galaxy is even smaller than a grain of dust in the vast universe with a diameter of more than 13 billion light-years, and beyond the Milky Way, there are galaxy clusters, and in addition to galaxy clusters, there are total galaxy clusters, and the universe contains infinite total galaxy clusters, so the number of civilizations is far beyond human imagination.

How could there be no extraterrestrial civilizations?

"I think there should be, right?" Ji Ran thought about it and said conservatively.

"Fifth sister, do you think that our current science is more accurate than the science of 2,000 years ago? Can people 2,000 years ago predict science 2,000 years from now? The eighth sister asked again.

Ji Ran blinked strangely, this question is too simple, right?

"Of course not, there was no such thing as science 2,000 years ago, when people explained the laws of nature through religion and superstition, how could they know what would happen 2,000 years later? Naturally, our current science is much more reliable than the superstitions of their time. Ji Ran said as a matter of course.

"Well, since the fifth sister knows this, she should understand that our current science cannot explain the science of the future world, that is to say, the science we call now may be very unreliable in the eyes of future people thousands of years later, just like the superstition we look at the ancients two thousand years ago.

In other words, in the eyes of our generation, although the current science is advanced, it may not be the true truth of the universe, and there are always some phenomena that cannot be explained by modern science. The eighth sister said to Ji Ran.

"Oh? It seems to make some sense, but I haven't thought about it before. Ji Ran thought about it and nodded approvingly.

"Fifth sister, do you know that in ancient times, if someone said that the earth was not the center of the universe, but an ordinary planet revolving around the sun, what do you guess would be the outcome?" The eighth sister asked again.

When Ji Ran heard this question, he suddenly thought of Bruno and Copernicus, both of whom were the first to discover that the earth was not the center of the universe, one was tied to a cross and burned to death, and the other was a little smarter, and wrote heliocentrism before his death, and then published it when he died, otherwise, Bao Buqi would also be tied to the fire and burned to death.

Thinking of those who dedicated their lives to science, Ji Ran couldn't help but shudder.

"They were either burned to death or killed, because they exposed the truth, they let the maintenance of order in the ancient world be destroyed, although there are many people who know that they are speaking the truth, but if in order to maintain the truth, and let the relatively orderly world fall into chaos, the cost is too high, so, in order to maintain an orderly world system, the best way is to dispose of this part of the first people who discovered the truth, only in this way, can the world run smoothly.

The old world order will not be replaced until there is a completely new theory that can bring the world order to peace again. The eighth sister's words made Ji Ran pause, thinking about it carefully, it seems that it really makes sense.

"So, you are the first to discover the truth in our time?" Ji Ran asked in surprise and joy, as if he understood.

"What am I talking about? The fifth child's comprehension is the highest, and he can get through it at one point, but his memory is too poor, and he will forget about today's things if he can't keep them all tomorrow. The eldest sister smiled and touched Ji Ran's head and said.
