Now the situation is more complicated, the temperature in the spacecraft is slowly decreasing, but it will not drop to a certain extent, because there is a lot of magma at the bottom, it is heating up at all times!

Moreover, after people blocked part of the entrance and exit, the temperature has increased.

Fortunately, the purple metal with Noah's own heat resistance and heat insulation is so good that the heat is not transmitted to the radiation wall, and humans are not cooked.

The internal environment is very bad and needs to be urgently repaired.The problem should not be big.

The external environment can only be said to be very strange ... from time to time outside the spacecraft will have high-energy gamma rays passing through, and sometimes it will hit the spacecraft again to improve the kinetic energy of the spacecraft.

Scientists estimate that Noah is flying in space at extremely high speeds.

Yes, very high!

This is no joke, it can even be said... close to the speed of light!

"According to estimates, it should be 0.98 times the speed of light!"We are traveling at 0.98 times the speed of light!”

When it comes to this, a group of scientists have even forgotten many troubles, showing feverish colors, and have lamented eye-opening.

Thanks to the supernova explosion, humans are marching into unknown outer space at an unprecedented ultra-high speed!

The stellar explosion is a super powerful driving force, much more powerful than a nuclear bomb explosion...

At 0.98 times the speed of light, the relativistic effect is already very serious.In this case, the dynamic mass of the spacecraft changed from 1.0386 million tons to 5.291 million tons, about five times the original.

In other words, Noah accepted more than 4 million tons of mass in the supernova explosion, all of which were converted into the kinetic energy of the spacecraft.

It sounds exaggerated, but it is normal to think about it.The volume of Noah is so large and the density is almost zero (about 0.000073 kg/m3), which is easily pushed by infinite light pressure.

4 million tons of this mass is not much, the sun normal combustion, 1 second of mass consumption is this figure.Now the energy of the sun for 10 billion years is released in an instant, and Noah receives only one of the nine cows in the nine cows, which is only equivalent to one of three billion.

But this kinetic energy for humans, is simply outrageous, just relying on ordinary deceleration means, it is impossible to make the spacecraft stop!

Rockets in reverse?Don't think about it!

Fortunately, because of the strange nature of Noah, with the "beyond the deceleration scheme", as long as the material is thrown out, the spacecraft can quickly slow down.

So humans don’t worry about slowing down at all.For humans, the most important thing is to find a rich earth-like planet on the way forward, and then stop and keep mining and mining.

Talking about this, several scientists casually discussed it.

Meeting a planet?How easy it is to talk about...the universe is empty after all.The probability is very low!”

“Yes, but our spacecraft will only travel faster than 0.98 times the speed of light, not more slowly.Because the large-scale reconnaissance devices cannot detect the Noah, we can't accurately estimate it, it's just the most conservative estimate."

“Maybe faster!”

“The time-expansion effect of high-speed navigation can expand our search...”

He sighed and nodded his head again.

The mysteries of the universe are infinite, and one of them is the “relativistic effect” of high-speed motion.

The speed of light is a very magical speed.Even in a sublight-speed spacecraft, observing a beam of light inside or outside a spacecraft will find that its velocity is still the speed of light relative to the observer.Whether this beam of light is relative to the direction of motion of the observer or the same direction, it is still the speed of light in any case... This is the principle of the invariance of the speed of light in relativity.

The "relativistic effect" is divided into "time expansion", "scale shrinkage" and "move quality".For a high-speed moving object, observe it from the stationary side and find that its time will expand, the size will shrink, and the mass will increase!

But the high-speed moving object itself has no feeling.

“The time-expansion effect is very good for interstellar navigation, 0.98 times the speed of light, and we feel that the time becomes one-fifth of the original, which is very helpful to cross the long voyage time.”

“The three months we felt, the outside world was 15 months.So, according to the outer timeline, we have been 15 months since the sun exploded!Mars is 1.3 light-years away!

At this point, many scientists feel amazing.This is the real relativistic effect that humans are experiencing.And such a relativistic effect is good for humans, which means that you can fly farther in your lifetime!

Flying further means that the more likely humans are to encounter planets or stars!

"If we run into ordinary meteorites, let's forget it... we'll have to meet a planet rich enough to stop."

“Yes.”Yi Feng also agreed that if the mountains are not exhausted, they will never be satisfied with some ordinary meteorites.

Such high-speed operation opportunities are once-in-a-lifetime, and once humans slow down the spacecraft, they will no longer be able to accelerate it to such high speeds.

Humans don’t have the ability to detonate another star to propel a spacecraft.

Therefore, people's foothold must be found well, which cannot be satisfied with small meteorite groups.

Yu Yifeng has made up his mind that people will develop into a real interstellar civilization in a new foothold!

For ordinary people, the current psychological experience is very strange.Although the ultra-high-speed movement of the spacecraft has not changed people's daily life, in everyone's hearts, there is a feeling of heaven and one year on the ground.(In a spacecraft close to the speed of light, all physical phenomena are the same, which does not change people's daily lives.))

There is a very famous conjecture called the Twins paradox, which reads: There is a pair of young twin brothers, one of whom travels across a spaceship to travel close to the speed of light, while the other stays on Earth.

As a result, when the traveler returned to Earth, he found that his brother who had stayed on Earth was sixty years old, and his age had only increased by one year.

This twin paradox is caused by the “time inflection” of the relativistic effect.

Because of this psychological experience, it has triggered a wave of relativistic learning frenzy...

However, the new government is most concerned about whether it wants to know what the outside starry sky is like and where mankind has come.But it can’t be done now, not even scientists.

In this extremely high-speed situation, in addition to the high-energy radiation from the sun, even other particles in space are very dangerous.

The universe is close to a vacuum, but there are also a small number of particles.The number of particles in each cubic centimeter in interstellar space is about one.In the vast voids similar to those between the Milky Way and other galaxies, the number of particles per cubic centimeter is 10 minus 6, that is, only one particle within a cubic meter.

For sub-speed of light spacecraft, these almost stationary particles are simply a nightmare, and the two collide and explode to a certain extent!

Although the explosion of a particle is not high, it accumulates like the continuous bombing of tnt explosives.

Therefore, the surface of Noah explodes all the time, and the speed is gradually decreasing, but the process of this reduction is extremely slow.And after the high-energy rays from the sun hit Noah, it will still provide it with some kinetic energy.

Because of this, no detection instrument can directly detect Noah, otherwise it will be directly broken by interstellar particles or high-energy rays!

Even the gravitational wave telescope, in the spacecraft can not feel the external gravitational waves, must be detected.

Scientists are trying to solve this problem.

The simplest way is to put the large reconnaissance instrument on the side of the direction of Noah's movement, at least the interstellar particles can not hit.
