"I don't know much about this era, but humans have named that alien race "Scavengers".

It is a civilization that believes in the laws of the dark forest, believing that the resources in the universe are limited, but the civilization will not stop developing and expanding.

Eventually, there will inevitably be conflicts between civilizations over resources, so they will strike first and artificially destroy civilizations. ”

They entered a pure white laboratory, surrounded by many research instruments that Xia Lian couldn't read, and in the middle was a huge computing device, with a drawing board in the corner.

Xia Lian looked at Einstein's serious expression and smiled.

"But it doesn't matter to us, humanity will eventually defeat this civilization under the leadership of someone.

All we can do is try not to affect the established course of history.

The base will not be visited for a year or so, it has an advanced artificial intelligence, and it has a quantum computer with powerful computing power that can input data and simulate all physical changes.

You can do your research here with peace of mind. ”

"However, even the enemies faced by the humans of this era are so terrible, and how powerful will the enemies that the humans of the future will face?" Albert Einstein said.

Xia Lian's smile instantly stiffened.

Then, he complained, "Can you not say such a terrible thing with such a normal face." ”

"Just because you avoid it doesn't mean it won't exist." Albert Einstein laughed.

After a pause, he continued, "I can agree to your request to study this fifth overhead element, but I have a question. ”

He looked at Xia Liandao, "Why me?" ”

"You're Albert Einstein, aren't you?" Xia Lian said.

Einstein and Charlian looked at each other, and after confirming the seriousness in his eyes, his dead eyes brightened because of the gradual aging of his body.

He muttered softly.

"yes, I'm Albert Einstein."

"The gap between the times can be erased through learning, but the pure pursuit of truth is not shared by everyone."

Xia Lian smiled and took out the pill that Mercury had given him from his arms.

"It's AS2.0, and if you eat it, your brain will become a high-precision computer, and you will have access to the knowledge that has been accumulated by humans for generations over 10,000 years.

It will also treat ailments in your body, prolong your life, and allow you to regain your youthful strength. ”

Einstein took the pill and swallowed it in his stomach.

Soon, Einstein sensed the difference in his body, as micro-nano nanons devoured iron in the human body to multiply, replace blood, and repair the body.

He could feel his heart grow stronger, his breathing smoother, and his body, which had been weakened by old age, seemed to be a dry, almost withered tree that had finally received a rainstorm and was rejuvenated.

The wrinkles on his face seem to have disappeared a lot, and he is more than ten years younger.

But this is not what is contained in this pill, unlike the pill that Xia Lian ate, it also contains all the recorded human science recorded in the mind of mercury.

The moment AS successfully integrated his brain, a large amount of knowledge from the future was instilled into his brain.

Einstein's eyes widened, he seemed to have entered an unknown world, he swam in an ocean of knowledge, quantum mechanics, antimatter, new particles....

Countless sciences unfolded before his eyes, turned into his knowledge, and soon, he saw what he wanted to see most in this vast sea of knowledge.

"Unified field theory," Einstein muttered softly, "is that so..... They first unified it with quantum mechanics.

Standard Model .... Start with the microcosm, place the most difficult gravitational forces first, and start with the remaining three, clever idea, but not my style. ”

He seemed to be afraid that this knowledge was gone, and began to panic and began to write down formulas with a pen on the drawing board in this laboratory.

He muttered under his breath as he recorded.

"The strong force propagates through gluons, bundling upper and lower quarks, forming atomic nuclei. The essence of hadrons is the exchange of gluons between color and charge.

The electromagnetic force bundles the nucleus and electrons together to form atoms through the propagation of virtual photons, and the essence of the electromagnetic force is the exchange of virtual photons between electric charges.

The weak force is transmitted by the Z boson to the W boson, which converts the upper quark and the lower quark, and then the neutron and the proton are converted to each other....

Yang-Mills gauge field theory.... Unified three forces ....

The name.... Is it that kid....

And gravitons .... Does this thing really exist....

Sure enough, only by observing the stars can we find this breakthrough.

If I could have had these ....."

He looked a little crazy now, but Xia Lian could understand it.

There are four fundamental forces in the world, weak force, strong force, electromagnetic force and gravitational force.

Unification is the use of a theory to unify them and explain the universe with an equation.

It's not a mystical thing, it's like the periodic table that allows humans to understand the world better.

It is the most important foundation of many technologies.

For example, the gravitational manipulation technique used by mercury.

Of course, the difficulty of unifying the field theory is much more difficult than that of the periodic table.

Soon after Einstein established the special and general theories of relativity, his interest turned to a much larger goal: unified field theory.

Einstein's goal in establishing a unified field theory was to unify his theory of gravity, the general theory of relativity, with Maxwell's theory of electromagnetism. If successful, unified field theory will be the pinnacle of Einstein's work.

However, Einstein's progress was not smooth, and due to the limitations of computer technology, none of the results of any experiment could prove the relationship between gravity and the magnetic field of electric currents.

Although Riemann, who established the theory of curved space in any dimension, was convinced that both gravitational and electromagnetic forces could prove their unity by simple Riemannian geometric derivations.

But alas, apart from this, there was nothing in Einstein's mind that could prove his idea.

At this time, quantum theory was booming, a large number of excellent physicists devoted themselves to it, and few people followed Einstein to study the unified field theory.

Gradually, well-intentioned reminders or sharp criticisms of Einstein and the unified field theory followed.

Among the critics was Einstein's friend and colleague Wolfgang Pauli, who famously uttered a quote.

"God doesn't want people to put things together," he said. ”

Pauli uses this sentence to imply that the unified field theory cannot succeed.

Einstein spent his later years working at the Institute for Advanced Study in Princeton, where he spent half his life working on the unified field theory without success and without followers.

In 1955, Albert Einstein died alone.

The unified field theory is the only obsession and regret in his heart.

The establishment of a unified field theory is not a great feat that can be accomplished by one person.

After Einstein's death, dozens of the world's top scientists worked together and it took decades to establish a unified model of the three forces.

And even so, gravity has not been unified with the three forces, and they have no clue.

The difference between gravity and the other three forces is that gravity is a macroscopic force that is the force that exists in the stars, whereas the other three forces are microscopic forces and are interatomic forces.

The microcosm may still be observable, but stars are much more difficult to observe.

And Einstein alone wanted to unify the most difficult gravitational force with one of them.

In that era of limited technology, unifying the two was almost a miracle that could not be accomplished by human beings.
