Reborn Before the Apocalypse: My Backing is the Nation

Chapter 104 Gravity
Jiang Yang could clearly see that the passage, which stretched for several kilometers, abruptly ended here. Beyond that was a huge underground cavern.

Visually, it appears spherical, with a diameter of about one kilometer.

At the core of this spherical cavity, a circular ground is suspended, about six or seven hundred meters in diameter and with a total area of ​​about several hundred thousand square meters. One after another, uniquely shaped buildings, all emitting a soft yellow and white light, quietly sit on it.

It neither touches the sky nor the ground; it just floats there quietly, without moving.

This……

Is it anti-gravity technology? Or some kind of magnetic levitation technology, or some other unknown technology?
Looking down, you can see that the end of the passage is about a hundred meters away from the floating fortress.

Below was the cold moon rock, which was also tinged with a yellowish-white light by the reflection, and had no support.

"We need to find a way to get there and take a look."

Without anyone giving an order, at this moment, the same thought simultaneously arose in the minds of everyone, including Jiang Yang.

Clearly, those high-energy neutrinos that wiped out the entire human civilization originated from here!
"For a distance of over a hundred meters, we'll have to use an aircraft."

Tong Zheng's voice was calm and resolute: "We don't have ready-made aircraft, but we did have flat-plate thrusters before."

These propulsion units have now been converted into electric flatbed trucks by our side, and their engines have been removed.

But that's okay. Since it can be taken off, it can be put back on. It just takes a little time.

Jiang Yang didn't know what kind of training these astronauts had received on Earth or what skills they possessed, but it seemed that these disassembly and assembly tasks were obviously nothing to them.

In that case, we would need to return to the temporary camp first and then transport all kinds of supplies and equipment in.

After quickly determining the follow-up action plan, Tong Zheng issued the order: "All personnel, prepare to evacuate!"

There seemed to be no danger here. Jiang Yang also freed himself from the shock of seeing this floating fortress for the first time and hung the pistol he was holding on his waist.

But due to a lack of skill, it slipped from his hand and slid straight down the flat ground towards the end of the passage.

Jiang Yang subconsciously bent down to pick it up, but was pulled back by a strong and powerful hand.

Tong Zheng looked at him quietly: "No, thank you."

"it is good."

Jiang Yang originally thought that the pistol would fall directly to the bottom of the spherical cavity when it reached the end of the passage.

But the next moment, something unexpected happened.

After passing the end of the passage, the pistol did not fall. Instead, it seemed to fly on its own, continuing in the same direction and at the same speed, heading straight towards the floating fortress ahead.

Tong Zheng also witnessed this scene.

"We don't need to assemble the aircraft anymore."

He said slowly, "Outside the passage, there should be no gravity inside this underground cavity."

Without gravity... then the technology used by that floating city can be determined.

It's not magnetic levitation, but anti-gravity technology.

This technology exists only in the fantasy art of human civilization and has never appeared in reality.

Human scientific theories have failed to cover any possibility of anti-gravity technology.

Let alone antigravity, at this stage, people haven't even figured out what gravity actually is. Relativity argues that it's not a real "force," but rather an external manifestation of spacetime curvature caused by the influence of matter with mass.

Quantum mechanics considers gravity to be a fundamental force, just like electromagnetism, the strong nuclear force, and the weak nuclear force.

The latter three fundamental forces all have corresponding particles as the carriers of the force, such as photons that transmit the electromagnetic force, gluons that transmit the strong nuclear force, and W and Z bosons that transmit the weak nuclear force.

Gravity should also be a force that propagates through gravitons.

Both theories have achieved tremendous success in their respective fields, propelling human civilization's technological advancements. However, on the issue of gravity, the two theories encounter serious mutual incompatibilities.

This is why human civilization doesn't even understand what gravity actually is.

If we can't even understand gravity, let alone anti-gravity technology.

And now, this technology is truly presented to Jiang Yang.

Well, while this is shocking, we've already witnessed even more incredible technologies like "negative matter fields," so the appearance of anti-gravity technology here doesn't seem so unacceptable.

Since there is no gravity here, crossing this distance of over a hundred meters to reach the floating city at the end of the passage is not difficult.

Tong Zheng's voice came again: "Number 2, Number 3, try to reach the floating city for reconnaissance."

"Yes."

When Zhao Jianguo and his companion reached the end of the passage, they first tried sticking their arms out of the passage to get a feel for it.

Afterwards, the third astronaut took out a rope and tied it around Zhao Jianguo's waist.

Zhao Jianguo stood at the end of the passage and slowly leaned forward until his body was level with the ground.

The rope in the hands of astronaut number 3 was taut, tightly securing Zhao Jianguo to prevent him from falling. Only when Zhao Jianguo's body was level with the ground did the rope slowly loosen.

Then, an astonishing scene occurred.

The ropes were no longer pulling him, but Zhao Jianguo's body remained suspended in the air, showing no sign of falling.

He bent his legs, then suddenly straightened them. The next moment, his body shot out nimbly in a straight line, like a fish.

The rope was pulled out as he charged forward.

He didn't rush out very fast, at most two meters per second. But in this vacuum and weightless environment, his speed and direction remained extremely constant, never changing.

He "flew" for several tens of seconds, flying straight to a point about two meters above the floating city. Then, his body suddenly plummeted and landed on the "ground" of the floating city.

It seems that the floating city has gravity. And judging from the speed of its descent, it is equal to the gravity of the moon in the passage at this moment.

Upon arriving at the floating city, Zhao Jianguo did not rush to explore the surrounding area, but instead secured himself. On the other side, the third astronaut also secured one end of a rope to the hydrogen bomb cart whose wheels were already locked.

He gripped the rope and climbed across with ease, just like an astronaut performing a spacewalk in space. The whole process took less than a minute.

The two figures then disappeared into the buildings of the floating city.

A few minutes later, a voice came through the communicator: "No threat detected."

"Walk."

Including Jiang Yang, all 13 people below him climbed over the rope.
