Time reversal, reversal is not only the appearance, but also some deeper things, such as the apple that he ate, if time is really reversed, the apple should be born out of nothing, in addition to his thinking, it should also be reversed. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

But no!

None of these.

The apple left his hand, but a new apple was not born out of nothing, it was still eaten, and Xiao Li's thinking was not reversed.

This proves that this high-dimensional space is not as capable of going backwards and moving forward at will as Xiao Li imagined, and the basic laws of the four-dimensional universe still work on this high-dimensional space.

Time can be lengthened, shortened, but irreversible.

This is the conclusion of Einstein's theory of relativity, which is related to the fact that the speed of light cannot be exceeded, that is, if the speed of light cannot be exceeded, time cannot be reversed; If the speed of light can be exceeded, time can be reversed.

With such a conclusion, the attraction of this timeline to Xiao Li suddenly decreased.

Xiao Li looked ahead, his gaze swept to a ball of light, it hung alone in the sky, except for it, there was no other matter in this high-dimensional space.

"Is this a gravitational source?" Xiao Li's eyes narrowed slightly, "Adam, fly towards the source of gravity." ”

The spaceship flew towards the ball of light, but soon Xiao Li sensed that something was wrong, "Stop." ”

"Adam, how many meters did we go just now?"

"3,720 kilometers forward."

"But we're not getting closer to the gravitational source." Xiao Li looked at the gravitational source and said, "This shouldn't be. ”

If the gravitational source is very close to him, then he should now touch the gravitational source; If the gravitational source is large, but it is only far away from him, so it appears small, then after he has traveled such a long distance, it should grow larger as the distance closes, but the gravitational source does not.

It was not affected by distance from beginning to end, and even when it was presented in his field of vision, the gravitational source did not change at all, and this inconsistency was the biggest anomaly in itself.

"Two possibilities!"

Xiao Li said firmly: "The first one, it is deceiving me, it uses a means similar to photon sequencing to conceal its location and deceive its eyes, but this method can deceive the optical telescope, it is impossible to deceive the radio waves, and no matter how it hides and deceives, as long as it still releases gravity and creates a force field, it is impossible to hide completely, and the attack of the dark forest cannot be so simple." ”

"The second is that it's not on the same timeline as me."

Time in this high-dimensional space is displayed in the form of an axis, and as long as the alien who created the Dark Forest attack places the gravitational source on another timeline, then even if he finds the location of the gravitational source, it is impossible for him to attack the gravitational source.

"If it's the second one, it's a big problem." Xiao Li muttered, not being on the same timeline means that he can't attack the gravitational source, in that case, what's the point of him finding the gravitational source?

The second option is the most likely.

"Adam, release electromagnetic radiation, target gravitational source."

The two ends of the spacecraft immediately lit up, and a large amount of electromagnetic radiation was released, detecting the presence of a gravitational source, but no!

Nothing!

Under the detection of electromagnetic radiation, the entire high-dimensional space was searched with the spacecraft as the center, but no matter other than the spacecraft could be found.

The gravitational source does not seem to exist at all, and there is no refraction, reflection, absorption, etc. of electromagnetic radiation.

There is only one explanation for this phenomenon.

"It's not on the same timeline as me."

Xiao Li had a headache.

How do I attack a gravitational source on a different timeline? Missile? Nuclear warhead? Laser cannons? No, these weapons have no way to attack a gravitational source on another timeline, and even any weapon on Earth can't attack a gravitational source on another timeline.

He thought about it, but there was no way to attack the source of gravity.

"Think again...... Maybe there is a way. Xiao Li was in a hurry, racking his brains to find a way to attack on a different timeline.

"Gravitational waves?"

He thought for a moment and shook his head, "No, although gravitational waves can cross dimensions and timelines, I don't have any weapons that use gravitational waves as an attack. ”

"The only thing that has to do with gravitational waves is anti-gravity."

Destroying gravitational sources by anti-gravity? No kidding, could he still create gravity, make the gravitational source fall, and then hit the ground? Don't forget, this is a high-dimensional space, it does not exist on the ground, and the only thing that will happen if it falls is a circular fall, which will never see the bottom.

"If gravitational waves don't work, is there any way to cross the timeline?"

He looked at the gravitational source, and suddenly thought of a solution in his mind, "Wait...... ”

"Why should I attack a gravitational source across the timeline?"

He's been thinking about how to attack gravity sources across the timeline, so he's stuck in a dead end, but he doesn't need to attack gravity sources across the timeline at all.

The reason why the gravitational source is in a different time axis from him is simply because this is a high-dimensional space, and time exists here in the form of an axis, but what if time does not exist in the form of an axis? Will the gravitational source be in a different timeline than him?

The answer is no.

If the gravitational source falls from the high-dimensional space to the four-dimensional universe, then the timeline that protects it will disappear completely, and he will not do whatever he wants at that time?

So he's just getting into the nitty-gritty.

Another way of thinking, the solution is so easy.

"Destroy high-dimensional space."

"But how to destroy the high-dimensional space."

He was caught up in another problem.

The high-dimensional space is based on the four-dimensional universe, and an additional dimension is added within a certain space to form an independent space-time space.

It is higher than the fourth dimension and lower than the fifth dimension, independent of the four-dimensional universe but belongs to the four-dimensional universe.

It is a relatively independent space-time.

If he wants to destroy the high-dimensional space, the easiest way is to eliminate the extra dimension, but how to eliminate the dimension is not clear to him at all.

Even in the high-dimensional space secrets given to him by the ghost, there is no information to eliminate the dimension, and it seems that there is no way to eliminate it after the dimension is built.

"The vacuum sphere may be able to use quantum transitions to jump the energy of the components of this high-dimensional space into the low-energy universe, so that it loses its support and collapses on its own."

This high-dimensional space does not appear to have energy and matter, but any high-dimensional space is made up of energy, and without energy there is no high-dimensional space.

"But I don't have a vacuum ball in my hand."
