Abnormal crossing

Chapter 49 Jump Point

At this moment.

Gu Wei didn't know that Milo had already filled his heart with flags. He was sighing at the captain's carefree attitude.

be honest.

If it were someone else, they might not choose to act this way in the face of this series of situations - according to Mee Mee's previous introduction, the spacecraft actually has a cyber version of soul-searching techniques that can crack consciousness.
Milo then looked around again, and the Wave Chaser paused: "In short, we still have too little information, so we can only make wild guesses."

"So we'll talk about this matter when we have follow-up news. The next mission is the key point. Mee Mee, how long is it until the jump point?"

Meow Meow replied quickly: "Right away, about half an hour."

Milo nodded when he saw this: "It's about time. Let's distribute the stabilizing fluid to everyone. This trip is a bit far and the jump intensity will be very high."

Meow Meow: “Got it.”

Not a moment later.

Tubes of green liquid floated precisely in front of everyone at the scene. It was the stabilizing liquid that Gu Wei had drunk before.

Gu Wei gently picked it up from the air and looked at it over and over again.

Why do you want to drink this again?

"Don't be surprised. This is a necessary process for interstellar travel. After a while, you will even find that drinking it has become a kind of life habit." Perhaps seeing Gu Wei's confusion, Kai explained while drinking: "Unless you are a metal life like Alelie, even if you have modified your body, it is still difficult to withstand the impact of entering the jump point."

Upon hearing this, Gu Wei looked at the stabilizing filling liquid in his hand again, raised his head and drank it.

Then, while feeling the liquid spreading in his limbs, he looked at Kai curiously: "Kai, what exactly is the jump point you are talking about?"

Jump point.

Gu Wei had heard Mie Mie mention this word as early as when he first traveled to the Puleng Puleng. At that time, the breakout goal of Milo and others was to reach the nearest jump point and escape.

So from a purely functional point of view, the general purpose of the jump point is not difficult to guess:

A long-threaded shuttle mode, either only one spaceship can pass through a jump point in a short period of time, or there are many optional destinations - otherwise Polna's people can catch up with Milo and others by just rushing into the jump point.

But on the other hand, Gu Wei didn't know what the specific process of this thing was.

"The jump point. Then you really found the right person." Kai glanced at Gu Wei, and his tone under the metal mask suddenly became a little subtle:

"When I took the hyperspace dynamics exam, I only wrote down a solution. I took the make-up exam for the whole course 17 times. In the end, I had to pay someone to help me with the make-up exam. Do you think I can tell you the answer? - Next time before asking a question, remember to look at other people's drawing styles first. Ask Jin!"

Gu Wei: “.”

So he looked at Jin again.

Seeing Gu Wei looking at him like a curious baby, Jin, who was looking up information on the side, originally did not intend to waste time, but then he remembered that Gu Wei's mecha disappeared right under his nose, so he hesitated for a moment and stood up from his seat: "Come with me."

Gu Wei followed obediently.

Then Jin took him to the other end of the main control room, pointed to an area that looked like a window and said, "This is the spacecraft's horizon screen, also called the star screen. You can directly see the outside scene. The jump point is in front."

Gu Wei heard the words and came to the location pointed by Jin, and looked out through the star screen.
An endless darkness appeared before his eyes, as if an abyss swallowed up all the light. It was quiet and depressing, making him unconsciously think of those unlucky readers before he traveled through time.

But after this initial, almost general, rough look, Gu Wei soon discovered some colors hidden in the darkness:
Under the endless darkness, there are a few faint points of light dotted in the distance - these points of light are not flickering, but emit a faint light continuously.

Like a lighthouse in the universe, it watches over the endless darkness alone.

If you look further away, you can even glimpse a few glowing interstellar dust lanes.

They float in the darkness like a veil, their glow is so faint that it is difficult to find them when you look closely.

after awhile.

Gu Wei discovered another special scene:

It was an area located slightly to the lower left in front of him, in which floated a small ball of light that was brighter than the other spots of light.

The small light ball was glowing white all over, but it seemed to have no substance, like a ball of sewing with many threads tangled together.

As the spacecraft sailed, the small ball of light became clearer and clearer in Gu Wei's field of vision.

So he vaguely guessed something, turned around and looked at Jin: "Could this be..."

"Yes, this is the jump point," Jin nodded. "Each jump point is associated with a large number of exit hubs. With it, you can easily complete cross-star or even galaxy travel. The jump point is also the most important navigation center in the Star Sea Era. Aren't you interested? Can you guess how it appeared?"

"Let me guess?" Gu Wei blinked and pretended to think: "Could it be that there is a place with negative energy density in the universe, where space-time can be bent into negative curvature, thus creating a channel that allows radial tidal forces to not affect speed and allows matter to pass through?"

As an astrophysicist.

The moment Gu Wei saw the jump point, the first thing he thought of was the Einstein-Rosen Bridge, also known as the wormhole.

The concept of wormhole can be traced back to 1916, when Austrian physicist Ludwig Frahm proposed the concept of wormhole.

In 1935, Einstein and Nathan Rosen perfected the wormhole theory.

They symmetrized the metric of the wormhole, introduced the radial component grr and the radial coordinate r0 of the throat of the wormhole, and made a mathematical model called the Einstein-Rosen bridge - this is the wormhole that spacecraft will pass through in almost all science fiction novels in later generations. It is really a mathematical model.
This isn't over yet,
In 1962, Robert Fuller and John Wheeler published a paper proving that if a wormhole connects two places in the same universe, then this type of wormhole is unstable.

That’s right, it’s a proof, not a conjecture.

A similar situation is the Alcubierre metric - in 1994, Alcubierre proposed a Lorentz manifold that allows a warp bubble to appear in an originally flat spacetime.

This thing has another name, called the warp engine╮(╯▽╰╭.

嗯，数学上也是允许曲速引擎存在的。（DOI 10.1088/0264-9381/11/5/001，这哥们还在X上发帖想演个三体角色）

In recent years, scholars at Penn University have even improved the mathematical model, using a warp loop to compress the negative energy required to drag less matter to a level close to that which the Casimir vacuum can bear.
Unfortunately, before Gu Wei traveled through time, many science fiction works only knew the results but not the reasons, resulting in many concepts supported by standard frameworks becoming streams of consciousness that were out of the framework.

"Oh, the phenomenon you mentioned does exist, but it has many limitations." Hearing Gu Wei's guess, Jin quickly shook his head: "The light-like geodesics of this type of wormhole will be trapped by the black holes that appear at both ends of the wormhole, and there will be huge tension at the throat."

"In this case, the negative energy matter required to pass through a wormhole is probably heavier than the entire Milky Way you came from, so generally no one would use this thing to travel through time."

"As for the jump point, it is actually a man-made passage."
