After receiving his dissertation yesterday, Eddington did not rush back to Cambridge, but went to the Royal Society, also in London, and asked the secretary of the Society to arrange a room for him to spend the night.

He wanted to see what Chen Muwu had written in this treatise on the theory of relativity, so that his old friend Albert Einstein could be so admired that he even sent a telegram to recommend it to him in the Far East.

If he thinks the paper is fine, Eddington will continue to send the paper to the editorial office of the Bulletin of the Natural Sciences for help in publication, as he has done before.

In fact, Chen Muwu's second paper on general relativity is not very profound.

He simply based on the gravitational field equation proposed by Albert Einstein in 1917 and solved the exact solution of this equation under several specific conditions.

Eddington's level of mathematics made it easy for him to understand the derivation in Chen Muwu's paper, and he also very much recognized Chen Muwu's first and second solutions to the field equations proposed by Chen Muwu in his paper.

Merely......

What is the "Chen Universe" proposed by Chen Muwu in the last part of the paper!

This derivation of the Chen universe is as impeccable as the previous two solutions.

Eddington was afraid that he had seen the wrong steps, so he put pen to paper and did the math, and the results were still correct.

It's just that the conclusion he came to after some pushing, but in terms of common sense, it seems very absurd.

In this rotating universe, the past and the future are inextricably entangled.

A person can travel back in time to any point in his own past if he can make a long enough round trip with the help of a galactic train that is close to the speed of light!

But Eddington always felt that this theory was extremely awkward.

Because according to the second law of thermodynamics, which he believes, entropy, or randomness, always increases, and time can only flow in one direction.

In other words, there is no way to recreate a few slices of bacon into a whole pig.

And the time travel proposed by Chen Muwu in the Chen universe is to enter the low entropy state from the current high-entropy state to the low-entropy state in the past, which is impossible to achieve!

The last part of the dissertation, Chen Universe, completely made Eddington fall into madness.

On one side is the second law of thermodynamics, which he grew up believing in, and on the other hand, the theory of relativity, which he now firmly admires.

However, these two theories have fallen into contradiction and irreconcilable in the universe proposed by Chen Muwu.

If he supported one of them, he had to give up the other.

Eddington didn't know where to go.

During the night at the Royal Society, Eddington slept restlessly, and I don't know if it was because he couldn't sleep well in his own bed, or because Chen Muwu's paper gave him nightmares.

The next morning, he woke up from his bed, and took the train back to Cambridgeshire from King's Cross Station.

Eddington felt that he could no longer understand whether the last part of the paper was wrong or wrong, and that he needed to go back to Cambridge to move the soldiers.

Ralph Fowler, a lecturer in mathematics at Trinity College and the only theoretical physicist in the Cavendish Laboratory, is responsible for providing data calculations and theoretical support to the experimenters.

Fowler was so beloved by Rutherford that two years earlier he married Rutherford's only daughter, Irene Marie, and became the colt in Cavendis's laboratory.

Fowler was Eddington's younger student at Trinity College, and the brightest of their class.

This gentleman has advanced mathematical ability, so at the first time, Eddington thought of Fowler.

Hurrying into the Cavendish lab, the first thing he met was the bearded Rutherford.

Seeing that it was Eddington, Rutherford smiled and said, "Arthur, why are you in such a hurry?" Why, are you going to send us a paper on the genius of China again? ”

One looks up at the size of the universe, the other looks down at the size of the atom, and the two don't see each other very often.

The last time we met, it was Eddington who sent Chen Muwu's first paper to Rutherford.

That paper solved the problem of gamma ray scattering that had plagued McGill since his college days, so Rutherford had a good impression of Chen Muwu, whom he had never met.

"Sir, it's true that I'm here this time because of that Chen Muwu, but there are a few things in his new paper that I don't understand, so I came here to discuss with Fowler."

Hearing that Eddington was looking for his son-in-law, Rutherford's eyes couldn't hide a smile: "Are you looking for Ralph?" You're just in time, he's just been in the lab, and he should be in his office upstairs. ”

"Thank you, Sir."

"It just so happens that I don't have anything to do now, I'll go up with you and see what kind of masterpiece our genius has sent this time!"

The two men walked up the iron staircase to the second floor and into Fowler's office.

Fowler was a little surprised to see his father-in-law come in with the seniors of Trinity College.

When he heard that the Chinese man from before had sent another paper, and Eddington asked him to see if there was any error in the comments, Fowler was a little dismissive.

He had read Chen Muwu's first paper before, which was completely a rudimentary physical formula and derivation, and he could only say that this person was very lucky and stumbled upon the correct answer by mistake.

But when Fowler took the paper from Eddington's hand and read it through from beginning to end, he was taken aback.

It was like, the last time we met, he was a toddler, but now that we see him, he's much faster than the Flying Scotsman, a non-stop express train on the Great Northern Line from London to Edinburgh.

How can a person improve so much in such a short period of time?

Unless he's clumsy!

After Fowler read the paper, he felt that there was nothing wrong with the mathematical logic.

He was afraid that his thinking would be led by the paper, and like Eddington, he checked the paper from beginning to end, and it was still accurate.

This mathematically infallible derivation leads to the result of a human time travel, which Fowler finds absurd, but has an indescribable beauty.

Seeing that Fowler had finished reading the paper, Eddington voiced the doubts in his mind.

In his opinion, the mathematical derivation of this Chen universe is incorrect, but I don't know why, it comes out with such a result that violates the second law of thermodynamics.

After listening to Eddington's words, Fowler fell into deep thought.

Could it be that today, between Einstein's gravitational field equation and the second law of thermodynamics, will we find a wrong answer?

This is Rutherford, who has been sitting on the sofa in his office, looking at the two people who are tortured by the papers, and speaks: "Arthur, I think you are thinking too much, but ignoring another point, that is, using the second law of thermodynamics to deny the impossibility of time travel is actually incomplete.

Maybe the second law of thermodynamics does prevent people from going back in time, but have you ever thought that it doesn't stop us from going through time travel to the future? ”
