I really don't want to lie down and win

"Are you on the rooftop of the magic capital, or in our own laboratory?" Xu Mang asked Brother Chuan Xiao on the phone.

"Own laboratory."

"what?"

Xu Mang was stunned for a moment, and asked in surprise, "You...don't you need the help of a sky instrument?"

"not needed for now."

"Because we have encountered a big problem!" Brother Chuan Xiao sighed: "The product of the first chemical reaction in the universe is much more difficult than we imagined, Xu Mang... Hurry up and solve it."

"Oh..."

"Talk to me first."

"I can't make it clear on the phone. I'll send you the information."

"it is good!"

hang up the phone,

Within a minute, Xu Mang received an email.

When I opened it, there were several documents inside.

After reading it carefully, Xu Mang knew what kind of problem Brother Chuan Xiao had encountered.

Although it is known that helium hydride ion is the product of the first chemical reaction in the universe, how can it be determined that it is the first atomic combination in the universe?Or are those stars containing helium-hydrogen ions?

According to the data, the helium hydride ion is composed of helium atoms and protons. The exposed protons in this structure make the helium hydride ion a very strong acid, so it can bind to any substance that collides with it.

Once,

Formation of helium hydride ions triggers the formation of the first hydrogen molecule, which soon follows other atomic combinations, followed by two extremely unstable particles that then disappear into the natural world.

How to solve it?

This is no longer pure chemistry, but the scope of cosmic chemistry, a marginal subject between astronomy and chemistry.

whoops

Oh my God!

This is so much harder than fragile topology!

but,

It's also much more interesting.

Xu Mang began to explore this issue in depth. First, he had to solve the environment of the early universe. Fortunately, people had studied the early universe before, and Xu Mang got a lot of ready-made information.

Generally speaking,

The first generation of stars in the early universe was too large and unstable.They quickly form heavier elements through internal nuclear reactions before ending their short lives in violent supernova explosions.

During the explosion, the elements carbon, oxygen and silicon were scattered into the surrounding nebula and introduced the chemistry of the universe into a second phase.Two new compounds, water and carbon monoxide, have emerged that dramatically increase the efficiency of nebula cooling, spawning vast numbers of smaller stars.

finally,

formed the present universe.

And Xu Mang wanted to find traces of helium hydride ions in the process.

"This shit..."

"It's annoying!"

Xu Mang's head suddenly grew a lot, and it was as difficult as finding a needle in a haystack.

Xu Mang started from scratch, studying the relationship between helium hydride ions and stars, and soon he discovered that the energy released between atoms and molecules changes during the collapse, and there is a completely different mechanism between the two.

A nebula of atomic hydrogen collapses, and it gets hotter and hotter until the thermal motion of the atoms is sufficient to balance the tendency of the collapse, resulting in a structure of nothing, which is the hypothetical environment.

But the emergence of molecules changed this assumption. Molecules radiate energy outward, so the nebula can be further cooled and continue to collapse. Although helium hydride ions are not the best coolant for nebulae, they are enough to allow nebulae with a mass of one million times the sun to complete spontaneously. gravitational collapse.

Then these nebulae later evolved into the first stars, gradually forming the brilliant universe that is now.

at this time,

Xu Mang came up with an idea. Maybe there are some nebulae in the current universe, and their physical conditions are similar to those in the early universe. In this way, helium hydride ions are likely to be produced, and as long as the density is high enough, they can be detected arrive.

but...

This is no longer as difficult as finding a needle in a haystack, it is simply finding a needle in the universe.

Facing the vast universe,

Xu Mang felt that human beings are so small, and their power is so insignificant in front of the universe, but... the power of thinking can span the time and space of the universe, and thinking can reach any corner of the universe.

Give it a try!

......

I wish the motherland mother a happy birthday and a happy holiday everyone! ! !

Chapter 500 A nonsense idea (3/3, add more for Shuoyou)

Gravitational Wave Detection Laboratory,

Brother Chuan Xiao and the four members sat in the conference room, worrying about how to find helium hydride ions. Although Xu Mang was already dealing with this problem, judging from the clues he had so far, it is estimated that even he could not handle it well. .

And not only him, even NASA, ESA and other space agencies have been unable to find evidence of the existence of such ions for decades, because the space telescopes they use cannot detect the signal of helium hydride ions from other molecules identified from the mixed signals.

Even in 1925, chemists had already synthesized this ion in the laboratory...

"Ugh..."

"How to do?"

"I feel like we're completely chilled." Zhang Yapeng said helplessly, "I don't even have a clue now, it's just... almost autistic, should we analyze the molecules of the whole universe and compare them one by one? "

"Don't bullshit!"

"NASA has used this method a long time ago, but it still failed in the end." Dong Yu said: "I still want to find a reliable method."

Reliable...

Finding the first chemical reaction product in the entire universe is not very reliable in itself.
