1900: A physics genius wandering around Europe

Chapter 496: The concept of wormholes! Shocking the whole audience! The ability to shrink the earth into an inch! The means to travel through the sea of ​​stars!
When the island universe theory was proven, the vastness of the universe was completely revealed to all astronomers.

The M31 nebula alone is more than 100 million light-years away from Earth.

The number of galaxies in the universe can be described as countless as the grains of sand in the Ganges.

If the universe were static and fixed in size, then humanity would not be too desperate.

Because theoretically, as long as human civilization can continue to be passed on, sooner or later it will be able to reach every corner of the universe.

However, the fact that the universe is expanding shatters this only hope.

It will be impossible for humans to ever go beyond the scope of the observable universe.

Because the speed of light cannot be broken!
At this moment, when someone suddenly said, "Maybe, I have a way."

Everyone was shocked immediately!

They quickly looked over there, their expressions becoming even more surprised.

"Oh my god! It's Professor Bruce again!"

"His brilliance was so dazzling that with just one sentence, he became the absolute center of the meeting."

"However, mass and information cannot exceed the speed of light. How can we break this barrier?"

Everyone was curious.

Hubble, Yu Qingsong and others were shocked.

This is the second time Professor Bruce has taken action!
You know, the old man hasn't actually started his speech yet.

The first Astronomical Congress was destined to become a legendary conference in the history of astronomy.

At this moment, Li Qiwei did not go up to the podium, but said directly:

"During this period, I have re-studied the field equations of general relativity."

"After listening to Yu Qingsong's reasoning just now, I suddenly thought of a very interesting solution."

"According to general relativity, space-time can be curved."

"So, can space and time be distorted or even formed into a loop?"

“I think there should be such a solution.”

"What does that mean?"

"I think there may be a narrow passage in the universe that connects two different spacetimes."

"No matter how far apart these two time and space are, even if it's hundreds of millions of light years."

"As long as we pass through this space-time channel, we can reach the other side instantly."

"Since this channel is caused by the structure of the universe itself, it does not violate the special theory of relativity."

"Let me give you another vivid example."

At this time, Li Qiwei asked Haier for a piece of manuscript paper.

He marked both ends of the manuscript paper.

"Suppose, this piece of paper is our universe."

"The two places I drew on the paper are 1 million light years apart."

"If you walk normally, you can only walk across the entire paper, from one point to another."

"But if I fold the paper so that the two points coincide."

"Then the two points can be connected instantly."

"This space-time channel is like a bridge, connecting the space-time of different regions together."

"If we find it, we may have a means of interstellar travel."

"Of course, all of the above are derived from the theory of general relativity."

"Whether it exists in the real universe or not still needs to be verified."

quiet!
Deathly silence!

When Li Qiwei finished his conjecture about the space-time channel, everyone in the conference room was shocked.

This theory was completely beyond their imagination.

The horror of general relativity's control over the universe once again deeply shocked everyone.

Soon, heated discussions broke out in the conference hall.

For astronomers, the existence of space-time channels is like an element from science fiction.

However, it is derived through the general theory of relativity.

This is a true scientific conjecture!
Although few people present truly understood the general theory of relativity.

The mathematics in it is a bit too unfriendly for astronomers.

But the one who proposed the theory now is Professor Bruce himself.

In this world, no one understands Guang Xiang better than him.

After hearing the theory of space-time channels, Hubble was so surprised that he couldn't close his mouth.

According to the general theory of relativity, such a magical space-time structure can be derived.

This is a bit too incredible!
Since the publication of general relativity, countless people have devoted themselves to its research.

But among these results, the space-time channel is definitely the top result.

It is even comparable to the five great prophecies.

At this moment, Hubble's admiration for Ridgway reached the highest level.

"Professor Bruce can open up a new research direction with just a few words."

There is no doubt that the concept of space-time channel will inevitably cause a sensation in the fields of astronomy and physics.

However, I'm afraid only physicists are qualified to study it.

Because it requires very advanced mathematical knowledge to analyze structures such as space-time distortion.

The duty of astronomers is to actually find this strange existence in the universe.

Yu Qingsong did not expect that his speech would lead to Professor Li's attack again.

With such a comparison, he deeply felt the difference between the light of fireflies and the brilliance of the full moon.

The concept of the observable universe makes all astronomers despair.

However, Professor Li failed to surrender!

In front of him, even the vast universe is just a thought away.

"This is exactly like the Chinese myth of shrinking the earth into an inch!"

Unparalleled supernatural powers!
With one step, he reached the edge of the universe, and the road was paved under his feet!

Yu Qingsong's face was full of fanatical worship.

Gao Lu and others nearby were all confused.

Their expressions hadn't changed since Hubble took office.

It's been shock, shock, and shock again.

The conference was so exciting that they felt like they were attending an alien conference.

The gap is so big that it is unimaginable.

Compare the current situation in China with the content of today's meeting.

Gao Lu and others couldn't help but laugh.

I almost laughed to tears.

"I now understand how ridiculous the behavior of those warlords is."

"Compared with Professor Li, they are like the difference between apes and modern humans."

At this moment, everyone suddenly thought of Professor Bruce's previous declaration.

He wants to lead mankind to explore the sea of ​​stars.

Everyone thought that it was just an ambitious expectation, just a facade, not a real crossing of the galaxy.

However, today, Professor Bruce used his extraordinary wisdom to prove to everyone:

He might have the ability to truly travel across the galaxy!

The concept of time and space channel made the whole audience excited!

Hai Er took the manuscript in shock, then silently hid it in his clothes.

He wants to pass this paper on.

Perhaps in the future, this piece of paper will become a valuable cultural relic.

After hiding, he asked excitedly:

"Professor Bruce, do you think this kind of structure really exists in the universe?"

Li Qiwei smiled slightly. The shock that everyone just experienced was within his expectations.

The space-time structure he was talking about was the famous "wormhole" in later generations.

In real history, in 1935, Einstein and Rosen jointly proposed the concept of a bridge connecting two different points in time and space.

It is called the "Einstein-Rosen Bridge".

In 1957, physicist Wheeler first used the term "wormhole" to describe this space-time bridge.

A wormhole is actually a solution to the general theory of relativity.

According to calculations, in order to resist the huge gravitational force inside the wormhole, another kind of exotic substance is needed.

Otherwise, the wormhole will collapse instantly as soon as it appears.

The existence of wormholes is proven by pure mathematical formulas, and they do not violate the laws of physics. Therefore, theoretically, wormholes can exist in the universe.

However, until later generations, scientists had not actually observed wormholes in macroscopic space.

Therefore, many physicists believe that wormholes may only exist at the quantum scale.

At the subatomic level, wormholes are forming all the time.

However, physicists have not actually observed wormholes at the quantum scale.

So, it can be said that so far, wormholes are still just a theoretical conjecture.

In later generations, there were also many theories about wormholes.

Some people believe that the two ends of a wormhole are actually two huge black holes.

Some people also believe that the two ends of a wormhole are actually a black hole and a white hole.

Enter from the black hole and exit from the white hole.

and many more.

Of course, all of the above are just conjectures.

So, in response to Haier's question, Li Qiwei said with a smile:

“That’s a difficult question to answer.”

"I have theoretically proven that wormholes can exist, at least according to general relativity."

"However, the specific mathematical derivation process still needs to be studied."

"If you force me to give an answer, I certainly hope it exists."

Everyone was filled with awe.

It seems that Professor Bruce is full of confidence.

However, Haier keenly heard a word: wormhole?
He hurriedly asked:

"Professor Bruce, what did you mean by wormhole?"

Li Qiwei said:
"Oh, that's the common name I gave to the space-time channel myself."

"I think calling it a wormhole is easier for people to understand and remember."

Haier, Dyson and others savored the name carefully.

Then, their eyes became brighter and brighter.

This name is great!
It is not only vivid, but also conducive to the spread of the concept of space-time channel among the masses.

Even people without any knowledge of astronomy can easily understand the meaning of wormholes.

Soon, the name of the wormhole spread.

At this moment, the atmosphere on the field was extremely exciting.

Then, people continued to raise various questions.

There were even some weird ideas that even Li Qiwei was amazed.

The universe is so vast and amazing.

Anything that looks or sounds incredible may exist and happen in the universe.

There is no longer any doubt about the expansion of the universe.

In other words, as people question and analyze the law of expansion from various angles, its correctness has been strongly proved.

The correctness of the law of expansion means that the fifth general prediction of the expansion of the universe has been verified.

This is probably the most important event in the field of astronomy this year!

There is no doubt that Hubble became famous in one battle!

Even his status will be elevated to an unimaginable level.

In a few decades, he would be considered America's greatest astronomer.

But in real history, Hubble did not win the Nobel Prize.

I have to say, this is a pity.

Host Augusto is numb.

He had never experienced a meeting like this in his life.

All kinds of theories and concepts that shocked the academic world were thrown around as if they were free.

Island Universe Theory;
The law of expansion;

Space expands faster than the speed of light;
observable universe;
Wormhole.

Taken individually, these concepts would have been enough to overwhelm the audience at a large astronomy conference.

But today, they are just the content of Hubble's speech.

This feeling is just like eating all the delicacies from land and sea until you vomit.

However, the many astronomical giants present will definitely not be satisfied.

Augusto said in a loud voice:

“Let’s thank Dr. Hubble for his wonderful speech!”

Wow!
Thunderous applause suddenly broke out in the conference hall.

Hubble's experience and his achievements deeply touched everyone.

Born as a genius, he studied under Professor Bruce.

While his peers had already become influential in the scientific community, he remained unknown like a hermit.

Ten years have not dulled his enthusiasm and perseverance.

Become famous all over the world!

This story will surely inspire more young people who love science.

Fate always favors those who work hard!
At this moment, Hubble stood on the stage, and his heart suddenly calmed down.

Everything is settled.

His journey did not end, but had just begun.

"There are still many unknowns waiting for me in astronomy."

As Hubble stepped down, the atmosphere in the venue began to become restless.

The long speech did not make everyone mentally exhausted. Instead, it made them feel as if they had been injected with chicken blood.

Because there is only one person left to give a speech.

And he is the one that everyone is paying attention to today!
Although Hubble's achievements were extremely amazing, everyone believed that the content of the following speech would not disappoint them.

Besides, Hubble only proved what the man had predicted more than ten years ago.

Hubble's success only served to highlight the man's terrifying power.

At this moment, Augusto was very excited and he said loudly:

"Next, let me welcome Professor Bruce to give his final sharing report!"

Wow!
Thunderous applause!

Great attention!

Everyone is looking forward to this scene.

No matter how great Hubble's achievements were, no one else had a chance.

I can only shout a few words of awesomeness.

But Professor Bruce is recognized as a pioneer in the field.

The theories and conjectures he proposed are often endless treasures for later generations.

Li Qiwei stood up, turned around and waved to everyone with a smile.

Then he came to the podium again.

As soon as he opened his mouth, he made all the bigwigs in the audience burst into laughter.

"To be honest, I'm a little nervous now."

"Hubble's speech was so amazing that I'm afraid no one will be interested in listening to mine."

Hubble smiled sheepishly.

He stole the show today.

Li Qiwei said with emotion:

“He didn’t let me down.”

"In my opinion, Hubble is the sailor of the galaxy world, leading us to explore the vastness of the universe."

This comment, which was both intimate and highly appreciative, fully demonstrated Professor Bruce's care for Hubble.

From then on, Hubble had a nickname: the sailor of the galaxy world.

Then, Li Qiwei changed the subject.

"But I'm not such a bad mentor."

“Eddington proved that starlight was bending, and Hubble proved that the universe was expanding.”

"I also want to prove a broad prophecy today."

"Oh, strictly speaking, it should be half proof!"

Everyone was shocked!
