Undergraduate, Haven't Brought It

"How are you feeling?" Bai Jing asked, retracting his Gravity.

"I... I don't think I can feel the Hulk anymore!" Banner's face showed three parts surprise, three parts grief, and four parts confusion.

It was natural to be happy that the Hulk, who had troubled him for so long, was gone. But the Hulk had also been with him for five years.

Even a cat or a dog would develop feelings after five years.

"Actually, I have some sad news to tell you!" Seeing Banner's somewhat happy expression, Bai Jing put on a sorrowful face and said, "Actually, the Hulk has only left temporarily!"

"Temporarily?" Banner was stunned.

"I found a hole inside you. The other side of the hole is full of that green energy that allows you to transform. I've only absorbed the energy on this side of the hole for now, but the energy from the other side is still seeping through. It'll recover its original scale in no time!" Bai Jing described the hole. "Do you understand what I mean?"

"A hole?" Banner blinked. "Inside me, moving with me? And connected to another world?"

Bai Jing nodded.

"This..." Banner frowned and thought for a moment. As a top physicist and biologist, he habitually tried to explain things with scientific theories.

"Could it be because that beam of gamma rays pierced through some kind of pocket dimension?"

"What is a pocket dimension?" Bai Jing asked.

"We generally believe our universe is a perfect three-dimensional universe, but nothing in the world is perfect. It might develop wrinkles, it might twist..." Banner said. "If a piece of paper, at a certain point, gets wrinkled, a second plane not belonging to this paper will be born. The same applies to the three-dimensional universe. If it wrinkles, a second universe attached to our universe will be born!" Banner continued. "This universe might be very small, or it might be very large. It might have the same rules as ours, or it might be completely different. In fact, our own universe might be a wrinkle on another universe. It's like a pocket on someone's clothes, so we often call such universes pocket universes, or pocket dimensions!"

"That sounds quite easy to understand!" Bai Jing nodded. Wasn't this just the concept of great worlds and small worlds, often used in Xianxia novels in his previous life?

"However, there was no evidence of pocket universes before. I should study this universe. Perhaps I can discover something, like the energy that exists in this universe, and why it can make me transform!"

"So the energy inside isn't gamma ray energy?" Bai Jing was taken aback when he heard this. He had been absorbing that energy as gamma ray energy all along!

"Gamma rays were like the key to open that door. The energy inside is definitely not gamma rays. I've never found gamma rays to have the ability to make someone transform," Banner shook his head.

"Okay!" Bai Jing nodded, but he was a little worried. He had just absorbed so much energy, would there be any problems?

However, he didn't feel any negative changes in his eyes. Instead, his vision had improved significantly.

"But before that..." Banner looked at Bai Jing. He had to rely on Bai Jing.

After all, in this world, no one else could help him heal besides Bai Jing.

"Don't worry, leave it to me!" Bai Jing nodded, then took out his phone and called Ryan.

"A boat will come to pick us up soon!" Bai Jing said.

"Okay!" Banner nodded, then looked at Bai Jing again. "Is your ability also due to radiation?"

"No, that's not it!" Bai Jing shook his head. "I think it's probably due to spacetime compression that gave me superpowers!"

"Oh, oh!" Banner nodded. Since Bai Jing didn't want to say more, he naturally didn't ask further.

"Oh, right, Dr. Banner, are you recruiting researchers or doctoral students?" Bai Jing asked again.

"Huh?" Banner scratched his head. "Of course, I'm qualified to supervise doctoral students, but I was engaged in classified missions at the time, so I didn't. Is something wrong?"

"I just received my admission letter from Columbia University and plan to study there. Wouldn't it be better to have a scientist by my side to learn from directly?"

In the Marvel universe, Banner was among the top three smartest people, second only to Mr. Fantastic Reed and Doctor Doom.

Let alone his seven degrees, he later developed a device capable of traversing parallel universes and time, which was incredibly awesome.

Compared to him, Tony Stark was a mere child. Peter Parker, who invented the web-shooters, had a picture of Banner posted in his classroom when he was in elementary school.

Imagine the kind of people whose pictures were on your elementary school classroom walls.

Learning from someone like him, Bai Jing felt no shame whatsoever.

"Haha..." Banner was quite happy. "Columbia University's standards are very high, but they don't mean much to us. As long as we study physics, we can understand everything in this world!"

When talking about his field, Banner was undoubtedly proud.

Although he was also a biologist, biology was actually something he learned on the side. He usually introduced himself as a physicist.

Because physicists held a higher status.

Of course, he didn't need to introduce himself, as his research projects had a significant impact on the world, and few people didn't know Banner.

He studied Quantum Field Theory, which was the highest level among physicists, at the very top of the natural science hierarchy, and together with General Relativity, it was known as the two giants of natural science.

Nuclear physics, particle physics, atomic physics, chemistry, astrophysics, mechanics, solid-state physics, mechanical engineering, fluid dynamics, sociology, electromagnetism – all were subordinates to Quantum Field Theory, lacking any prestige.

Of course, Banner was very humble and not someone who looked down on others.

By the way, Yang Zhenning was also a scientist in this field. His peers in this field included Feynman, Pauli, Heisenberg, Tsung-Dao Lee, Schrödinger...

"Quantum field theory is a physical theory that combines Quantum Mechanics, Special Relativity, and Classical Field Theory. It is generally used to describe multi-particle systems, especially those involving particle creation and annihilation processes!" Seeing that the boat hadn't arrived yet, Banner decided to teach Bai Jing some basic concepts.

"To study Quantum Field Theory, we first need to know what a particle is and what a field is. Particles are the smallest substances that we have confirmed can exist in a free state with our current experimental capabilities, such as electrons, photons, neutrons, and protons, which were the first batch of particles we recognized. Now we have discovered a large number of particles, such as mesons and resonance states. Currently, there are over a hundred types of particles..."

Bai Jing looked bewildered. What was he talking about?

"As for fields, they are another form of matter's existence. The main characteristic of a field is that it permeates all of space. They penetrate and interact with each other. Each particle corresponds to a field. The excitation of a field manifests as the appearance of particles, and the de-excitation of a field manifests as the annihilation of particles..."

"By the way, do you have any foundation in Quantum Mechanics and Particle Physics? What did you study in university before?"

Finally, there was a sentence Bai Jing could understand.

"I studied Electrical Engineering and Automation?" Bai Jing felt a bit embarrassed. Other sciences were at least on the natural science hierarchy, but his field wasn't even qualified to be looked down upon.

Banner remained silent, thought for a moment, and hesitantly replied, "Undergraduates? I haven't taught any!"

Bai Jing was speechless. Suddenly, he turned his head and pointed towards the distant lights. At that moment, he felt the yacht's engine sound was so…

"Dr. Banner, the boat is here!"

"Oh, let me recommend a few books for you first. You can teach yourself, and come ask me if you run into any difficulties..."

"Okay, okay, okay..."
