"This ......" Chen Muwu originally thought that he only needed a polite word to leave this visit, but as soon as they met, Eddington pulled him to discuss physics problems, "Sir, how can I say it, I get this Chen universe, and it will only appear when the universe constant Λ is negative." However, according to Dr. Einstein, the cosmological constant should be greater than zero in order to stop the collapse of the universe.

"To be honest, we still haven't figured out the nature of the cosmological constant, so there's no need to worry too much about a solution that only exists in an ideal situation."

Chen Muwu wanted to get this problem over as soon as possible.

Because not to mention him, even experts in this field a hundred years later have not figured out how to reconcile the contradictions.

Chen Muwu's words obviously did not ease Eddington's worries.

However, when it came to cosmological constants, another new idea rose in Chen Muwu's heart.

To prove that the universe is not static, as Einstein envisioned, but expanding, requires the observation of redshifts.

To observe redshifts, you must first calculate the distance of several nebulae, including the Andromeda Nebula, from the center of the Milky Way.

Nowadays, people don't even get a definite result for this distance, and mistakenly believe that Andromeda is contained in the Milky Way, which is why they are called "nebulae" (those outside the Milky Way are called galaxies).

And in front of me, there happened to be an astronomer.

Eddington has helped himself so much before, so can he repay the favor by telling Eddington how to find the distance, and then he will personally uncover the biggest mistake his good friend Einstein made in his life?

Just thinking about it, I think it's kind of interesting.

Eddington didn't know Chen Muwu's thoughts, but he saw that Chen Muwu didn't mean to say any more, so he started another topic: "Chen, now that you have arrived in Cambridge, what are you going to do next?" Do you continue to study your gamma ray scattering, or do you want to throw yourself into the arms of relativity? ”

"Sir, I'm going to design an experiment to study the scattering of light. As for the theory of relativity, I don't have any new ideas at the moment. ”

Seeing that Eddington was visibly lost, Chen Muwu then added: "However, when I was sailing on the steamer, I had some new ideas about astronomy. I think it won't be long before I'll be coming here more often and asking you for advice, sir. ”

"I look forward to your arrival at any time, but it may not be convenient for the last ten days and half a month, and I am going to London to attend the Duke of York's wedding."

Two days ago, Zhu Zhaoxin had already told Chen Muwu the news, and today, he heard it again from Eddington.

It seems that now these British people really love their monarch and their royal family from the bottom of their hearts.

It's not like the little old lady Prime Minister, who hasn't survived a single cabbage in his tenure, was as wild as he was when he was young.

……

Coming out of the observatory, Chen Muwu came to the Cavendish laboratory with another gift and knocked on the door of the office of his teacher and immediate boss for the next few years.

Unlike Eddington, a polite gentleman, Rutherford did not look like an intellectual at all.

His burly figure makes him more like a blue-collar worker, or an old farmer who has worked hard in the fields all his life.

Rutherford is fifty-two years old, with piercing blue eyes and a walrus-like beard.

The first time he shook hands with Chen Muwu, the latter felt a strong hand from it.

"Welcome to Cavendish Labs, lad!" Rutherford's voice was loud and full of neutrality, which made Chen Muwu inexplicably have a sense of déjà vu of the bald Bob in the tavern battle chess, "I can't wait to see what kind of new surprises your arrival will bring us!" ”

With that, Rutherford stuffed the pipe he had brought with him with dry tobacco, and put the struck match together, and the pipe burned like a volcanic eruption.

"Sir, this is my ......"

"Eh, I don't like to hear that in the lab, you can call me Director, you can call me Teacher, or just call me by my name, Ernest." Rutherford said with a smile.

"Director, this is a small gift I brought from my hometown," Chen Muwu put the same thing as he gave to Eddington on the desk in front of him, and took out the ivory cigarette holder he bought when he was anchored in Colombo from the pocket of his suit, "I heard that you like to smoke, this is an ivory cigarette holder I bought locally when I passed through Ceylon." ”

The current empire on which the sun never sets, but there is no such thing as animal protection.

Under the grey skies of London, there would never be a Swedish Joan of Arc with a shy face, frowning and shouting "Oyster Daddy Oil".

Rutherford accepted the gift unceremoniously and thanked him: "Thank you, Chen, this is the most intimate gift I have ever received.

"Since you came to the laboratory, then we are a family, you don't have to be restrained if you have any ideas, you can bring them up to me or James, as long as it's not that damn universe, the Cavendish laboratory will provide you with the greatest support.

"Chen, I hope you can put down the energy you have invested in the theory of relativity and the universe, stop doing those unrealistic theoretical researches, and work with us to explore the atom and the wonders of the microscopic and wonderful small universe within him."

James is Rutherford's assistant and second-in-command of the entire laboratory, Chadwick.

And the so-called small universe is not the burning thing in Saint Seiya, but refers to the atomic solar system model proposed by Rutherford himself.

Before, Eddington asked him to give up the atom and concentrate on the theory of relativity; And now Rutherford has asked him to abandon the theory of relativity and focus on the atom.

When did he Chen Muwu become so sought-after?

And, why choose one or the other?

Of course I want them all!

Chen Muwu thought for a while, and then said, "Director, thank you for your love." I did have a new idea on my way to England by boat. But it's not about atoms and radioactivity, it's about visible light. ”

"Visible ......light," Rutherford repeated, "I see, you must be wondering if electromagnetic waves in the visible light band can also produce the same scattering as gamma rays, right?"

"Well, in this laboratory, in addition to atoms and radioactivity, it is time to engage in other aspects of research. Hearing about your project, I think Baron Rayleigh III in Heaven would also be very happy. ”

Rayleigh III, the second director of the Cavendish Laboratory before Thomson Sr., was a full-fledged scientist.

In chemistry, he discovered the noble gas, the element argon, and in physics, he proposed the Rayleigh scattering formula on the scattering of visible light.

Chen Muwu didn't expect Rutherford to be crooked, and guessed what he wanted to do in the next experiment.

"When I come back from London after I attend the Duke of York's wedding, I'll ask James to arrange the equipment for you, how about it?"

Yes, another person who is going to the wedding of the little prince.

Knowing that this was the case, Chen Muwu felt that he should also stay in London and stay in the legation for a few more days to see this rare diorama.
