Although Fang Ge is not an astrophysicist, he still knows a little about the material composition of the universe.

The current universe is composed of dark energy (vacuum zero-point energy), dark matter, and light matter (positive matter, antimatter, photons, neutrinos).

Dark energy accounts for 70% of the mass, dark matter accounts for 26% of the mass, and light matter as we know it accounts for only 4%.

For the universe, human beings are still too small, and cognition is just a peep in the tube.

The existence of dark matter and dark energy is also a mechanism for maintaining the universe today, without the existence of dark matter and dark energy, our solar system and the universe would not be where it is today, and even human beings may not exist.

"Teacher, are you saying that part of the essence of life is dark matter?" Fang Ge hurriedly asked.

"Let's do a little experiment!" Huang Mingzhe turned around in response to the question.

Fang Ge followed Huang Mingzhe to the 5th floor of the inner city of Fire Day 1, where there is a stand-in robot Internet service area.

Lying in the survival module, Huang Mingzhe smiled and said to Fang Ge: "Let's go to the Frozen Mars Scrap Ship Observatory together." ”

"No problem."

Fang Ge herself was in the state of a stand-in robot, and when she parked the stand-in robot back in the storage box, she activated a stand-in robot located at the Ice Mars Scrap Ship Observatory.

……

Ice Mars Ship Observatory.

In the storage room of the stand-in robots, the storage boxes of the two stand-in robots lit up with red lights, and the nanobots immediately covered the body, forming the appearance of the two people.

"Let's go!"

The road was unimpeded, and Huang Mingzhe, who had the authority of the chairman of the Science and Technology Commission, could naturally directly enter the advanced biochemical laboratory.

Da Hai, who was busy with the synthesis of life essence, didn't notice that the two of them walked in, but his assistant reminded him that Huang Mingzhe and Fang Ge had arrived.

"Chairman of the Board, Academician Fang, welcome to the Scrap Ship Observatory." The huge sea felt a little restrained.

In fact, at this time, he not only felt restrained, but also went up and down in his heart, after all, there was no way to synthesize life essence, and he was probably worried that the Science and Technology Commission would doubt his ability.

Huang Mingzhe, who saw that the other party looked flustered, waved his hand: "Don't be nervous, I'll just make a real one." ”

Huge Hai, who breathed a sigh of relief, hurriedly said, "If the chairman has any needs, just command." ”

"Equipped with 10 grams of life essentia, is there a gravitational mass meter here?"

"No problem, there's a gravitational mass."

"Go get ready!"

Panghai immediately arranged experimental materials and equipment.

And Fang Ge, who was silent on the side, already understood Huang Mingzhe's thoughts.

In less than three minutes, Da Da Hai took 10 grams of life essence, and the purified life essence was a translucent lilac crystal.

After passing through a test tube equipped with life-like essence, pour 1 gram into a vacuum degenerate vial to activate the gravitational mass meter.

Start the neutrino atom scanner on the side, insert the probe into the degenerate state bottle, and soon the number of atoms in the degenerate state bottle and the number of types of atoms in the degenerate state bottle will appear on the display.

Press the impurity removal to remove the atoms in the vacuum bottle except for the vital essence.

Draw the gourd in the same way and put the remaining 9 grams of life essence into a vacuum bottle, which is also to remove other impurities.

Huge Hai and the others were confused, only Fang Ge understood what the teacher was doing.

Press the switch of the gravitational mass meter, and then the weight of 10 vials of life-derived mass is displayed with an accuracy of 10 billionths of a gram.

Immediately, Huang Mingzhe injected the same number of atoms and types into another 10 vacuum bottles, also eliminating impurities and activating the gravitational mass meter.

He added the mass of the chemical bonding energy.

"How is that possible?" Da Dahai wiped his eyes, and then carefully looked at the comparison of twenty sets of data, and he was stunned.

The same type of element, the same number of atoms, and even the same factors of tope and chemical bonds, should have the same mass.

However, there was an error of 0.14%, and the life essentia group had 0.14% more mass than the ordinary matter group.

Huge Hai couldn't help scratching his head and cheeks: "What the hell! How can there be 0.14% more mass out of thin air. ”

Worried that something was wrong with the instrument, he replaced it with a gravitational mass meter, and the result was still exactly the same.

"Teacher, it seems that you are right." Fang Ge said with admiration.

The huge sea full of mud, hearing Fang Ge's words, could only look at Huang Mingzhe with a blank eye, hoping to give an explanation to explain the terrifying phenomenon in front of him.

For a scientist, two elements with exactly the same conditions end up with different qualities, and there is a huge error of 0.14%, if the cause cannot be identified, it is estimated that life will be doubted.

"It's dark matter." Huang Mingzhe explained.

Dark matter? Dark matter! Da Hai's eyes widened, and the doubts in his heart suddenly became clear.

Ignore the huge sea of shock.

Fang Ge and Huang Mingzhe discussed, and the two of them could already affirm that the extra 0.14% of the essentia of life was the dark matter component.

As for why it is not dark energy, because dark energy is vacuum zero-point energy, the nature of this thing, the new human beings have long studied through the energy siphon effect.

For dark matter, Huang Mingzhe actually has a theory.

It's just dark matter that can be combined with light matter, and it is the first time that new humans have discovered it.

In the past, human observation technology could not directly observe dark matter, but after the new era, the existence of dark matter has been detected through sophisticated gravitational wave detectors.

As one of the products of the Big Bang, dark matter and light matter accounted for more than half of the total mass of the universe in the primordial universe.

In modern times, only 4% of light matter remains, and 26% of dark matter, and more than half of the dark matter and light matter have disappeared.

So where did they go?

The answer is naturally in dark energy, after the Big Bang, the universe entered a state of redshift expansion, and the force that pushes the expansion of the universe is dark energy.

It can be simply understood that dark energy is matter that manifests itself as universal repulsion, while light matter and dark matter are matter that manifests itself as gravitational force.

Over time, dark energy and devouring more and more dark matter and light matter, turning them into dark energy, will not end until the redshift expansion of the universe reaches a critical point.

In fact, this situation is very easy to understand, in the nuclear fusion reaction and the antimatter annihilation reaction, there is a loss of matter, and some of these losses are converted into photons and neutrinos, and some of them are turned into thermal energy.

Eventually, this heat energy will be increased by entropy to vacuum zero-point energy, which is turned into dark energy, which will drive the expansion of the universe.

In fact, this is a very helpless reality.

In order to ensure that the density of zero point energy does not decrease, the universe will spontaneously produce an entropy increase effect, turning dark matter and light matter into zero point energy.

And the gravitational pull of light matter and dark matter itself is a counterweight to the expansion of the universe.

As more and more dark matter and light matter are swallowed, the gap between gravitational and universal repulsion will become wider and wider, and the expansion of the universe is accelerating.

You must know that the universe was only about 13.8 billion years old, and most of the dark matter and light matter were swallowed up, and it is also unknown whether there will be 13.8 billion years in the future.
