"It's a little scary."

After Tang Rui got up, he went to the laboratory and began to build a space telescope.

After all, if there are massive stars in that area, you will know by taking pictures.

There's no point in guessing.

What extraterrestrial civilizations monitor Earth's spacecraft.

Joke.

An alien spacecraft with one-third of the mass of the sun, what material is it made of?

Not to mention how the material is.

An alien civilization that can build such a massive spaceship has long been able to shield itself from gravity.

We're here on Earth, and we all know how to make planes invisible.

Don't aliens know that gravitational waves reveal their existence? Is it possible?

Tang Rui manufactured a separate optical quantum information capture device, then added a set of optical arrays, put a shell on the outside, and installed a set of ultra-high-speed optical image cameras and lenses in the middle.

After you finish it, add some reinforcement directly.

[Item: Space Telescope for Large-Area Light Quantum Information Capture]

[Experience: 0/58000]

[Enhanced: Ultra-long-range wide-area optical information capture system]

[Attributes: 160% increase in detection range, 140% increase in detection accuracy, 120% increase in optical information capture ability]

[Source point: 17682.26]

Tang Rui looked at the system panel and felt pretty good.

"Red Lotus, transport this device to point L2 of Lagrange, and start probing that area."

"Yes, master."

After receiving the order, Honglian pulled the space telescope away, and he went home to eat.

I got up early in the morning to work, and I haven't eaten breakfast yet.

Before he finished his breakfast.

A message came from the space command center, asking what he was launching into outer space.

Tang Rui replied with a space telescope.

After learning the news, the space command center was excited, after all, they studied all night, and they didn't determine what the massive star was.

Now that Tang Rui has launched the space telescope, it must be for this matter, and then they just have to wait for the news.

At noon.

The space telescope was sent to point L2, which is also the best place to observe outside Earth.

"Deceleration is complete, enter the gravitational equilibrium zone."

"Attitude adjustment is complete, turn on the optical array."

Under the control of the red lotus, the telescope, which had been in the state of flower bones, opened the external optical array at this moment, and it looked like a blooming flower.

The stamen in the middle is the ultra-high magnification lens and camera.

"The spectral analysis equipment is activated, and wide-area detection begins."

"Area light locked, analyzing ......"

"Analysis complete, target locked, optical capture system activated......"

With the launch of the space telescope, the massive star outside the solar system was quickly locked.

With the collection of optical information, the image begins to become clear.

A minute later.

A brownish-black planet appears on a holographic projection screen, with scanned data next to the image.

It has a radius of 4,217 kilometers and a mass 0.7 times that of the Sun.

Normally.

A planet of this size and mass should be a white dwarf.

But even fools know that a white dwarf is not brownish-black, and even if its brightness is low, it is not so dim.

Tang Rui looked at the image in front of him and frowned.

He wasn't interested in what kind of celestial body the planet was, he was concerned with whether the planet was a natural or artificial object.

You say it's a natural celestial body.

I've never seen such a special planet.

You say it's in the celestial bodies.

There seems to be no signs of man-made modification on the upper surface.

It's weird.

Tang Rui studied for a long time, but he didn't come up with a reason.

He really doesn't know much about astronomy.

"Red Lotus, continue to track and photograph this planet, and then send the shooting data to the space command center."

"Yes, master."

Tang Rui didn't understand the situation on this planet, but he also knew the seriousness of the matter.

It doesn't matter what the situation on the planet is.

It's almost in the solar system.

The planet is currently flying in the direction of the solar system, only 72 astronomical units away from the sun.

One astronomical unit is 150 million kilometers.

That's it.

The distance between the two is 10.8 billion kilometers, which is quite a long way.

But here's the thing.

The solar system and this planet can almost be said to be face-to-face in both directions, like a man and a woman in love, about to embrace.

Both are about the same speed.

The solar system is moving at a speed of almost 220 kilometers per second.

Knowing the speed and distance, even elementary school monks can calculate the time, and the answer is 285 days.

That is, in 285 days, a special planet with a mass of 0.7 times that of the Sun will plunge headlong into the solar system.

What will that look like?

The entire solar system will be rewritten, and the orbits of all planets will become chaotic.

When the time comes, maybe Mars will collide with Venus.

Neptune will smash into Jupiter.

It's hard to say.

What will happen to humanity then?

If you don't open it, there is a 90% chance that it will perish.

It's hard to say whether the Earth can continue to exist.

In other words.

The end of the world is coming.

The other side.

All institutions in various countries around the world began to study this celestial object after receiving the data relayed by the domestic space command center.

Tang Rui didn't know much about astronomy, so he couldn't see what the situation was on this planet.

But astronomers figured out the situation as soon as they saw the photos and data.

This is a black dwarf.

Not because of its color, but because it is dying.

A black dwarf is the outcome of the long-term evolution of a white dwarf or brown dwarf, which means that its predecessor may have been a white dwarf, but it has been too long and the evolution is over, and it has become like this.

It's like stars evolve and eventually become white dwarfs, neutron stars, or black holes.

The result of natural evolution.

The problem is that it takes 200 trillion years for a normal white dwarf to evolve into a black dwarf.

How many billion years has the universe been born so far?

13.7 billion years.

So where do black dwarfs come from?

Could it be that they came from another universe?

That's not scientific, right?

All right.

Regardless of where this black dwarf came from, where do humans go from here?

After Tang Rui finished eating at noon, he went to the meeting.

Needless to say, the content of the meeting was not to be said.

Discuss the future of humanity.

There are just over nine months left, less than ten months left.

How?

"Academician Tang, what is your suggestion?"

"What else is there to say, I must run away."

Tang Rui replied without hesitation.

Lest there be a natural disaster of this level, even if he chooses to hang up, there is nothing he can do.

If it's an asteroid, no, even if an ordinary planet is going to hit the earth, Tang Rui has a way to kill that planet.

It's not that the Star Destroyer Cannon can't be studied.

Ordinary planets are still fragile.

But lest a hard black dwarf star composed of electronically degenerate materials be used to prevent a hard one, and the Star Destroyer Cannon is useless.

The Sun collides head-on with a black dwarf, and it's hard to say who wins or loses.

So.

There is no other way but to run away.

"There are less than ten months left, and even if you build a spaceship, you won't be able to take many people with you."

"There are many ways to run, run away in a spaceship, run away with the moon, or even run with the earth, depending on how you choose."
