After dealing with the affairs of Vega's side.

The Biosphere headed straight for Kepler 83142b, the destination of the first phase of the expedition 13 light-years away.

Wei Ming is tired of the slow journey, and if he continues to maintain a speed of 0.85C, it will take 4.8 years, and it will take nearly five years to arrive.

What if the biosphere speed increases to 0.99C?

With a seven-fold time dilation effect, it only takes 1.86 years to reach 83142b – less than two years.

In the past, before Xiao Hei didn't devour Vega, let Xiao Hei drag the ecosphere number, not that he couldn't cross the 0.85C upper limit and accelerate to a faster degree.

But as long as he speeds up slightly, Xiao Hei feels a little unbearable.

The faster the speed, the exponential increase in energy consumption, if it is forcibly increased to the level of 0.99C, in order to maintain this speed, Xiao Hei will lose 1% of weight every day, and after a hundred days, the oil will run out, and it is estimated that it can be withdrawn into Wei Ming's body.

Forcibly maintain high speed, and the final result is to be forced to ashes.

But this time.

After the small black mass is increased to the equivalent of two suns.

Now dragging the ecosystem, it can not only easily accelerate to the level of 0.99C, but also maintain this speed for a long time with a fairly small consumption.

Why is this happening?

"The greater the mass of a black hole, the greater its impact on space-time, and the easier it is for the objects around it to reach close to the speed of light."

Long Tianhao explained: "This is like the working mode of the curvature engine, as long as it generates a strong enough gravity curve to interfere with the space-time in front, and the plasma engine behind it, and then applies a thrust, it does not need to consume too much matter and energy to make the spacecraft reach a very high speed." ”

"A black hole with twice the mass of the sun, if it has an impact on space-time, the density of the space-time curve can be increased by more than seven times, which corresponds to a speed of more than 0.99C, and if the mass of the black hole is larger, the density of the space-time curve will increase to seventy times or seven hundred, which means that the spacecraft can reach a speed of 0.999C and 0.9999C, and it will not bring too much consumption to the black hole."

"And beyond the upper limit of the black hole's capabilities, forcibly achieve a faster speed, then the mass of the object will increase, bring additional energy consumption, serious overdraft, and of course feel powerless and unbearable."

"So you're saying that the black hole pulls forward, and the curvature engine works exactly the same way?"

Wei Ming thought for a while and asked: "The speed that the ecosphere number can reach is completely related to the mass, the larger the mass of the black hole, the closer it is to the speed of light?" ”

"Yes."

"Can you exceed the speed of light?"

Wei Ming asked, "Since this is already equivalent to a curvature engine, it shouldn't be difficult to exceed the speed of light, right?" ”

"Can't!"

Long Tianhao shook his head and said: "The speed of light can only be infinitely close, there is no way to exceed it, even if the ability of the curvature engine is already very powerful, but as long as it does not deviate from the category of classical space-time, no matter how dense the space-time curve is, the maximum speed is infinitely close to the speed of light, unless, we are no longer in the classical space-time, breaking this environment." ”

"What kind of space-time environment is not considered a classic space-time, so that it can exceed the speed of light?" Wei Ming asked again.

"Within the horizon of a black hole, somewhere like that."

"Then you're going to die in a moment?"

Wei Ming shook his head: "You can't even escape the light in the horizon, even if you can live if you enter it, but don't think about coming out of it again, you can't get out!" ”

"However, how do god-level civilizations achieve faster-than-light activities, they can break through the speed of light casually, why can't we, break through the speed of light barrier, are there other methods and paths?"

God-level civilizations must also live in this universe.

Why can they break the speed of light, but Wei Ming, who has Xiao Hei, can't break through that barrier?

"There's a second way."

Long Tianhao nodded and said: "In the early stage of the Big Bang, our universe reached the scale of the Milky Way in just a few seconds, which shows that the expansion speed of the initial explosion is far faster than the speed of light, indicating that under the dominance of a certain energy, space-time has expanded beyond the speed of light." ”

"Second, our universe is expanding at an accelerated pace, and galaxies at the edge of the universe are moving away from us faster than the speed of light, so that we can only observe galaxies within the range of 13 billion light-years farthest, which is not as large as the universe."

"What drives the accelerated expansion of the universe is the dominant dark matter and dark energy, which have a more obvious impact on space-time, or in other words, dark matter or dark energy, which does not necessarily promote the movement of matter itself, but makes space-time 'flow'."

"If we can collect a large amount of dark matter or dark energy in the future, we can use its 'accelerated space-time flow' property to create a 'dark matter engine' or 'dark energy engine' to push space-time forward flow, and there is a curvature engine in front of the spacecraft."

"Under the dual drive of dark matter engine + curvature engine, it is completely possible to break the barrier of the speed of light and enter the faster-than-light flight."

Dark matter.

Dark energy.

I didn't expect their existence to be so miraculous, they could accelerate space-time, and finally make the universe extremely empty, sparse, and cool, and become an endless dark and cold frozen dead domain - this is the true end of the universe, not a return to the origin of the explosion.

Of course, the universe is still far from ending.

Wei Ming's concern is that there is no way to find and capture dark matter and dark energy.

Is there a distribution of dark matter in the Milky Way?

"Yes."

"Over the years, using gravitational lensing, scientists have found a large number of areas where dark matter exists, is distributed and enriched, and in some places, even individual dark matter galaxy clusters have been formed, which are huge in scale, with a total mass exceeding that of the Milky Way, and far more than one," Long said. ”

"Around the Milky Way, there are multiple dark matter companion galaxies."

"There are not many dark matter distributions in the Milky Way, but some traces can be found in general, and as long as we are willing to pay more than 200 years of time and cost, we may find dark matter in the vicinity of more than 100 light-years."

"Then put it on the agenda and make a relevant capture plan."

Wei Ming said lightly: "On the one hand, it is to achieve the speed of light, on the other hand, we are too ignorant and know too little about this aspect, if we don't capture and collect some and study it in depth, it may become a fatal shortcoming." ”

You must know that in the recent research of scientists, dark matter accounts for 26.8% of the total amount of the universe, dark energy accounts for 71%, and normal matter accounts for only 2.2%, that is, 97.8% of the universe is actually composed of invisible and intangible dark matter dark energy.

The water content of biological jellyfish in the ocean is 98%.

This universe, like jellyfish, has a very small proportion of important substances, but there is a lot of transparent water, and it is easy to get sun-dried jellyfish skin, but how can the water in it be purified?

Perhaps, this is a difficult problem that scientists will study for a long time.
