Testimonials

In fact, as early as last year, Rainbow began to think about what to write when he finished his testimonial, thought a lot, and thought about it all the time, and always thought that as long as the battleship was really finished, as long as he wrote down the four words of the testimonial, he didn't need to think about it next, and he could write tens of thousands of words without panting.

But now, the battleship is really finished. Now, Rainbow has really written the words "the whole book is finished", and really wrote the title of the testimonial. Then, Rainbow was dazed and sat in front of the computer, not knowing what to write for a long time.

It seems that there are a lot of things to say, a lot, from the death of the hamster raised by the rainbow last year, to the time when I went out during the day today, I almost accidentally bumped into a girl because of illness and dizziness, I want to talk about it. But I don't know what to say, I really don't know what to say.

Then just say whatever comes to mind.

In fact, I feel really sad now, from tonight onwards, Rainbow will no longer have to continue to think about what plot to write tomorrow before going to bed, and from tomorrow, Rainbow will no longer have to think about updates. The rainbow seemed to be relieved, and seemed to be relieved for a while. But I always felt very lost in my heart.

At the beginning, I always felt that the daily update task was very hard, and I hated to sit in front of the computer to code words, but unconsciously, the daily code words have become a rainbow living habit, and have been integrated into the rainbow's life. Just like our hometown, when we stay in our hometown, we always want to run out, but once we leave our hometown, we can't help but start thinking, even if we know that we will continue to be annoyed when we return to our hometown, but we still can't help but think about it.

Perhaps, people are so hypocritical.

The battleship has been written for a year and five months, with a total of 3.3 million words and more than 1,000 chapters. The battleship has brought great changes to Rainbow's life, and it has also witnessed Rainbow's stumbling life. But fortunately, the rainbow has finally come over and come to the present, just like the battleship was once interrupted for half a month, once every three days, but now, it is finally finished.

It's done...... There is no need to worry about Xiao Yu's fate, no need to help Xiao Yu think about how to get out of the predicament, no need to think about how to create a conspiracy to deal with Xiao Yu, no need to think about logic and plot, no need to think about anything, so his head is empty.

When you read this testimonial, it will probably be at noon. And the writing time of this finished testimonial, well, Rainbow looked at the lower right corner of the computer, and it was twenty-three fifty-seven, three minutes before tomorrow.

It was still raining outside, and the raindrops were falling on the rain shield, ticking, like someone was constantly beating on a piece of iron, very annoying, but also very ethereal, so that the rainbow's thoughts seemed to float into the endless universe and stood with Xiao Yu.

Xiao Yu said, we are all addicts. However, in the face of the last puff of drugs and the answer to the ultimate question that has been pursued for tens of millions of years, the rainbow made Xiao Yu choose to give up. Rainbow thought, even if Rainbow didn't arrange it like this, if Xiao Yu really existed, Xiao Yu would choose to give up.

At this last moment, Xiao Yu resolutely broke free of his **, because Xiao Yu knew that when he swallowed this last mouthful of drugs, his life would lose all meaning, just like a defender.

The apologists are terrible and at the same time pathetic. The defender had calculated almost everything, but he had not calculated what a terrible future he would face when he really took this final step.

Having said that, it seems that there is no point in what the answer to the ultimate question is. But there must be many people who are curious, so Rainbow will briefly talk about their understanding.

The understanding of the rainbow is that there is no meaning. The existence of something is existence, and meaning is only an attribute given to it by human beings, it is non-essential, subjective rather than objective. As for why the universe exists, and how the universe exists, perhaps it is just a program created by some great alien civilization, who knows.

However, there is a very interesting calculation result to tell you, this result may give birth to a little wonderful imagination.

How would you feel if the rainbow told you that our earth, our solar system, the Milky Way, and our universe were all in a black hole? Does it feel like nonsense? No, don't rush to deny it just yet. Because there is a very scientific calculation that can change your opinion.

There have been a lot of explanations about what a black hole is in the battleship, so I won't say more here. According to the current theoretical system, the interior of a black hole is imperceptible, and no matter can escape from the black hole beyond the horizon boundary of the black hole. So, there are a few data that you can use to make a simple calculation.

A rough estimate of the total mass of the universe is 3.41 times 10 to the 53rd power of kilograms, note that this is a rough estimate and the actual mass is likely to be greater than this number. I won't write about the specific estimation process, but if you're interested, you can search for it yourself.

The event horizon radius of an object, which is the Schwarzschild radius, is calculated as Rs=2GM/Vc^2. Rs is the Schwarzschild radius of the object, G is the gravitational constant, M is the mass of the object, and Vc is the speed of light.

Then, the gravitational constant, which is G, is equal to 6.67 times 10 to the minus 11th power.

The speed of light is roughly calculated as 300,000 kilometers per second, or 300 million meters per second.

Now that we have the total mass of the universe, the gravitational constant, and the speed of light, let's calculate the Schwarzschild radius of our universe.

Before starting this calculation, let's calculate the Schwarzschild radius of the Earth and the Sun, verify our calculation process, and then compare it with the search results to verify our calculation.

The mass of the Earth is 5.98 times 10 to the 24th power, and the mass of the Sun is 1.99 times 10 to the 30th power.

The mass of the earth, that is, (5.98*10^24 kg) This data is brought into the Schwarzschild radius formula, (note,You can calculate it yourself,If you install the Sogou input method,Press the V key first,It will enter the mathematical calculation mode,Then enter the following formula),2*(6.67*10^-11)*(5.99*10^24)/(300 million squares),Yes,You see, The final result is 0.008866346667, which is measured in meters, that is, the Schwarzschild radius of the Earth is about 8.86 mm, which is about a little larger than a soybean.

Factoring the mass of the Sun into the Schwarzschild radius formula, the result is 2948 meters, which means that the Schwarzschild radius of the Sun is about 3,000 meters.

So...... What about bringing the mass of the universe into the Schwarzschild radius formula?

Press V and enter the following formula, 2*(6.67*10^-11)*(3.415*10^53)/(300 million squared), what is the calculation result? It's about 5.06 times 10 to the 26th power.

How big is the 26th power of 5.06 times 10? Let's do the math again. Divide this number by one thousand, and the result is about 5.06 times 10 to the 23rd power of kilometers, and then we know that a light year is 300,000 * 3600 * 24 * 365 is about equal to 9.46 times 10 to the 12 power kilometers, and then, we use the number 5.06 times 10 to the 23rd power of kilometers, divide by one light year, which is 9.46 times 10 to the 12 power kilometers, press V, and enter the following formula: (5.06*10^23)/(9.46*10^12), the result is 5.351555894 multiplied by 10 to the 10th power, taken as an approximate number, which is roughly 5.35 times 10 to the 10th power.

If we divide this number by 100 million, we get the final result of about 535, which means that the Schwarzschild radius of the universe is 53.5 billion light-years.

I don't know what dear readers and friends have discovered?

If you don't find anything, the rainbow will tell you. That is, the number of 53.5 billion light-years is much larger than the radius of the universe that we currently think of. The radius of the universe as we currently think is about 13.7 billion light-years.

It's like the Earth's radius is smaller than the Earth's Schwarzschild radius – 8.8 millimeters. If the radius of the Earth is less than the Schwarzschild radius, the Earth will become a black hole, and the radius of the universe is less than the Schwarzschild radius of the universe, what does this mean? Isn't it a description...... Is our universe also a black hole?

Could it be that all of us, our universe, is in a huge black hole? So, what could be beyond this black hole? Dear readers and friends, can you imagine?

Has this rough calculation process caused some reverie among readers and friends?

Tell the rainbow, where exactly did our universe come from? What exactly is our universe? And if we extrapolate from this, is it true that every black hole in our universe has another completely new universe that is completely different from ours?

This question probably has no one to answer Rainbow, and similarly, Rainbow has no way to answer everyone. Therefore, Rainbow chooses to arrange for Xiao Yu to give up knowing the answer to the ultimate question. This is the ultimate question of our universe, Rainbow doesn't know the answer, Xiao Yu can know the answer but Xiao Yu gives up, no one knows.

How mysterious and vast our universe is.

Well, take a break, get out of this problem for a while, and let's think about another question. This is also an interesting question.

First, imagine an all-encompassing, vast universe in which there are stars, planets, interstellar dust, rivers, and everything.

Okay, imagine that the universe is going on in everyone's mind. Now, following Rainbow's instructions, everyone first removes all the interstellar dust from their minds.

Well, there is no interstellar dust in the universe now. Then, take out all the stars again. Well, take out all the planets again. Then take out all the asteroids, take out all the river systems, take out all the black holes, neutron stars, white dwarfs, and take away all the light and radiation that is circulating in this universe......

In short, take away everything in your imagination of this all-encompassing universe, everything in it.

Now, imagine what else is in this universe?

Nothing, right? But there is nothing, and what is left?

Now, you have an empty universe in your mind, a universe where there is no matter, no energy, no time, no everything, nothing.

Okay, so it's time to end this imagination, because Rainbow can't lead everyone to continue thinking. I don't know why, whenever Rainbow imagines this step, there is always a very awkward and weird feeling, but it is unclear what is awkward and weird. Rainbow always wondered, what would it be like if there was nothing in this universe, if nothing was born in this universe, you and me, everything we know, not so many stars, in short, nothing?

Rainbow really can't be imagined, Rainbow believes that no one in this world can imagine it.

Since no one can imagine these things, then ...... Just give up this imagination and let everyone feel this way. Maybe in the future, you can think about this question once in a while and use it as a way to pass the time.

Well, that's all for the stuff in the book, and now, I'm going to talk to you about something else.

Rainbow has always wondered what it feels like when everyone looks at the battleship. Ignoring all the plots, do you feel the vastness and mystery of the universe?

If the answer is "yes", then Rainbow is satisfied. The book of battleships is not an ordinary online article, not centered on upgrading and stepping on people to create cool points, Rainbow just wants everyone to feel the magnificence of the universe, and uses Rainbow's own understanding to lead everyone into this mysterious world. Rainbow just wants to do that.

Well, with that said, what are you going to talk about...... This is the end of the testimonial.,More than a year,Only this time to write a testimonial.,The next time I finish writing this testimonial,I don't know if it's in the Year of the Monkey.。

It seems that everything else is finished. Let's talk about the process of creating this book, what? Rainbow has already said that? Well, forget it, let's not talk about the creative process, let's talk about something else.

An old author once said that the end of every book is a farewell to the reader. After the farewell, only God knows whether we can meet again. Because as an author, you can't be sure that your next book will still be loved by readers. Every book has a fixed readership, and even if your next book gets better, there will still be old readers who don't like it and give up. In this respect, the battleship is over, and it is time to say goodbye to some readers.

Rainbow wants to say that no matter whether we meet again in Rainbow's next book, Rainbow sincerely thanks you, thank you for this year and five months, more than 500 days, and more than 3.3 million words. Thank you for reading so much about Rainbow Bratch. Rainbow believes that the battleship will be a bright spot in your deep memory, and Rainbow also knows that every reader is also Rainbow's most valuable asset.

But there is no banquet in the world that will not be dispersed, and this goodbye is always to be said. So, let our memory stay at this moment, stay at the time when the rainbow writes the words "the whole book is finished", and let our good memories always stay at this moment.

No matter whether we can meet again in Rainbow's next book, Rainbow would like to sincerely thank you, especially Brother Yue, thank you for sending so many text messages to Rainbow for encouragement, thank you IP, thank you for sending dried meat for Rainbow, thank you book friend "Jue", thank you for your hospitality when Rainbow first arrived in Hainan...... There are many, many book friends, those who remember their names, those who don't remember their names, thank you very much, thank you sincerely.

At this point, it seems like it's time to finish. Well, at the end of this time, let's talk about Rainbow's plans for the next book.

Truth be told, until now, Rainbow hadn't figured out what to write about her next book. But one thing is for sure, and that is that the next book will still be relevant to the universe. As for the specific world structure...... Probably it will be fantasy, probably a story of a fantasy protagonist wandering in this universe, in this universe, there will still be neutron stars, black holes, river systems and all other essential elements of hard science fiction. Combining fantasy and hard science fiction can probably be regarded as an attempt.

As for the time...... It won't be released until more than a month later. Rainbow needs a break, and in the process of resting, Rainbow will think about everything about the new book and try to save a little manuscript. I hope this new book will still be enjoyed by everyone.

Okay, I talked a lot, and I looked at the number of words in the PS document, and it was more than 4,000 words...... So be it, I hope that in a month or a little longer, when Rainbow releases a new book, you can still see the familiar figure...... If you can't see it, it doesn't matter, there is no banquet in the world, Rainbow wishes you happiness every day, and I hope you can wish Rainbow a happy day.

It's really time to finish. Look at the time...... Whew, it's almost two o'clock, and I really feel like I'm on the verge of tears, and I don't know what to do. See you again then, and look forward to seeing you again.

Also,After the battleship is finished,Please vote for the satisfaction of the book.,If you subscribe to more than 30 percent, you can vote.,This vote is free.,You don't need to spend extra money.。 The place to vote is on the right side of the page of the battleship, and everyone can see it at a glance.

Well, yes, there's one last thing, the real last thing. It's going to end.,This is the last month of the battleship.,Rainbow hopes that the battleship can achieve a perfect ending in this last month.,So,Please, everyone.,If you still have a monthly pass in your hand.,Vote for the battleship~ Let the battleship get a good ranking.,Especially,The end of the month seems to be a double monthly pass on New Year's Day.,A little negligence in the ranking will fall.,The battleship was finished on the 23rd.,From the 24th to the end of the month, there was no update of the content.,There will be a big disadvantage in striving for a double monthly pass.,But, Rainbow still pleases everyone, in the last month of the completion of this battleship, it can still keep the battleship in the top six positions of the classified monthly pass~ Please!

Let's make our farewell ceremony more enthusiastic~

Rainbow Gate, respectfully
