On the outermost planet of the Kuiper Belt, a flat metal body of a certain thickness is flattened and fixed to the surface in a vacuum, with an organism attached to each side of the front and back, about the size of two human heads.

One of the two organisms, one of which is an organism that undergoes positive and antimatter annihilation, and the other is an ordinary piece of meat, is an experiment that tests the ability of proton lattices to block gamma rays.

"Let's go!"

With the arrival of a radio frequency band from far and near, the positive and antimatter inside the organism is annihilated, and a huge amount of gamma rays are released, and the proton lattice is impacted at close range.

A dazzling sun rose on the horizon of the planet's surface, and as the light faded, eight tons of matter were annihilated and evaporated.

Not a single cell survived in a large area of the planet, and as far as the eye could see, it was a lake made of lava, and because there was no atmosphere, there were no shock waves, and the energy of gamma rays washed over the surface and the layers of matter underground.

"Go and extinguish this lava, don't let this stuff interfere with the results."

Another radio communication command, the still intact rhizome quickly moved on the surface, using cryogenic substances such as liquid nitrogen to forcibly cool the lava in large quantities and reoccupy the lost area.

And the organisms wandering in space also began to travel to the very center of the lava lake after this communication was sent, where the positive and antimatter annihilation energy was released.

Then this organism from the universe near the surface of the planet saw such a scene: in this large lava lake, there is a small island, the area of the island is exactly the area of the proton lattice, and the place adjacent to the island is lava, very hot and hot, like a boiling soup.

Before the lava engulfs the island, the organism descends from the sky, captures the proton lattice, regains its altitude, and transports the subject to safety.

The collectors waited there early in the morning, and as soon as the proton lattice arrived, they began to confirm the condition of the organisms shielded by the proton lattice.

"How, how could this be"

"No, how can it still have a third of its cells necrosis?"

The proponent of the original plan looked at the damage information with some confusion, which did not match the physical model it had established, and the organism itself should not be harmed by gamma rays.

"Could it be that the gamma-ray photons knocked the protons away?"

"There is a possibility, but a third of the damage is still too much, and it should be a small probability that it will happen."

"We should ask and think, it has a higher depth of knowledge than us, and its brain is more flexible than ours."

"Agreed."

Connected to the communication with Si, and delivered the experimental information directly to Yu.

"Because the gamma rays pass through, of course, it's as simple as that." Si replied to the people who were experimenting.

"Is it because the proton was knocked away by a gamma photon?"

The proponents of the scheme asked Si that if Si gave a positive answer, then the collectors would consider thickening two more layers of proton lattice to avoid this situation altogether.

However, Si's answer came as a surprise.

"No, because there is still a gap in your proton lattice, and a small part of the gamma photons pass through the gap between the protons, harming the organisms hiding behind, and that's it."

"Huh? The distance between the protons is already less than the radius of the orbit in which the lowest energy level electrons travel, shouldn't gamma photons bounce off? ”

The proposer of this explanation could not help but be stunned, because the explanation given by Si did not match its physical model, and it was probably impossible for gamma photons to pass through the gap between protons, because it was below the radius of the electron orbit, and Pauli's law of incompatibility would not allow particles to pass through there.

The answer of the proposer is also a strange rhetorical question.

"Bounce off? Why does it pop off? The non-visible gamma photons do not interact with the proton electrically and cannot be 100% blocked from gamma rays unless the protons are in close proximity to each other. ”

After a moment of silence, combined with the actual experimental data, the proposer finally made a determination.

"That is, my physics model is wrong?"

"I want to know the reason for my mistake, think, send me the message."

Si did not hesitate to point out the reason why gamma rays pass through the proton lattice in the experimental results of his peers, the reason is that the photon is a boson, and the boson does not need to follow Pauli's law of incompatibility, and this law in quantum mechanics only applies to fermions, so the gamma photon can pass through the gap in the proton lattice, which the collectors involved in the experiment completely misunderstood.

After digesting the information, the proposer of the plan was disappointed, and some of them were disappointed, as were the other collectors.

"That's what happened, I was so excited before"

It's not that I'm disappointed in the performance of the proton lattice, even if it can't block all the gamma photons, it's much stronger than the previous heavy lead element protective layer, because the protons are dense enough, and a large part of the gamma photons will turn back after impact, so that the experimental subjects that should have become coke only survive one-third of the cell necrosis, which can be said to be very useful.

The frustration of the collectors is mainly due to the high expectations at the beginning, and the gap is unacceptable, and the image point is described as a group of top students sighing after the mock exam, holding a pile of test papers with more than 90 points and muttering about this question, that question should not lose points, I could have scored 100 points, and the test was smashed.

"Anyway, can't we continue to increase the pressure and narrow the gap between the protons so that they are next to each other? That would be 100% resistant to gamma photons. "There are gatherers who have come up with such ideas.

"Let's not talk about how to work in an extreme environment that creates that kind of pressure, and even if it is made, we will not be able to store and use it."

Other collectors explained that this state was too extreme, that there were no gaps in the protons on the whole surface, that the electromagnetic force between the protons would spill out, that it was a big problem just to maintain the pressure to ensure that it would not recombine with the electrically neutral particles, and that there were many reasons to consider, such as nuclear fusion

Today's proton lattice is a substable structure, and protons squeeze out the electron position, according to Pauli's law of incompatibility, electrons cannot form hydrogen with protons, as long as the pressure does not decrease, it can maintain this state.
