Maybe the advanced genetics and nanotechnology make the crew of interstellar flight immortal.

If we think carefully about the possibility that some civilization conquer the universe. Maybe in the distant future, we are that civilization.  There is a possibility that in a couple of hundreds of years in the future the first spacecraft will travel to Alpha Centauri. 

We must realize that civilization can travel hundreds or even thousands of years between the solar systems. If those creatures use giant artificial worlds called O'Neill cylinders. In those cylinders, rotational movement forms the artificial gravitation. 

The major problem of interstellar flight the enormous distances in the universe. If faster-than-light travel would not successful there is the possibility to use slow spacecraft for that kind of journey. There is the possibility that the advanced bio- and nanotechnology make the crew of that craft immortal. 

That means the nanorobots could fix the DNA of the crewmembers. When the DNA is damaged the nanorobot could make a copy of the original DNA. And then the nanomachine just replaces the old DNA by using new DNA where those damages are repaired. 

If the population of the crew is high enough that thing denies the degeneration. That hypothetical civilization could send a fleet of O'Neill cylinders. And each of those cylinders would be one population. In that model, the crew of each of the craft would degenerate. 

If those creatures would live in a zero-gravitational environment for their entire life their muscles would be so weak that they cannot be dangerous. That means the O'Neill cylinder's rotation movement stopped in that period.

There is one thing that became to my mind about "alien abductions"


Could those alien abductions made for installing the microchip or so-called record machine in the human nervous system. In that case, somebody would want to record things that person sees and senses by using those microchips. And when the person dies the stealth-craft would collect those microchips and download their information to the computers. 

This idea is from the idea that if researchers could decode the animal's EEG signals they could implant a microchip into the animal's brains. Then that microchip records everything that animal sees and feels. This could be a good way to collect data from the animal's life without disturbing their everyday actions. 


******************************************************************


But when the fleet of those crafts will come to target solar systems the population will be interconnected. And that thing allows the creation of the "super population" by using pure line hybridization. 

Another version is that our hypothetical civilization uses cloned embryos that are frozen in zero kelvin degrees. When the craft is closing its target those embryos will be grown in an artificial womb. The artificial womb is the container where cloned tissue would feed the embryo and fetus. Then the system transfers necessary data to their brains by using the electric stimulation that is driven through the cortex. 

Or maybe those travelers use powerful nanotechnology that allows them to repair their genetic material. So that the hypothetical crew will be immortal. In that model, nanomachines will repair the damaged DNA of that crew. 

Why we are making models of the hypothetical interstellar civilizations? The reason is simple. Maybe someday we are the civilization that travels in the universe. If we think that we exist when the Sun uses its final energy source and explodes as nova those people must leave this solar system. And if our descendants would travel to other solar systems they must collect all possible information about those targeted solar systems. 

There is lots of time for the first interstellar journeys. But maybe those things are possible after a couple of hundreds of years. Our society must change very much. And for those journeys is needed enormous technology and lots of work. And maybe we are the more intelligent aliens who meet primitive civilization in the Milky Way.

Use virtual "perpetual motion machines" and seawater as energy sources.

   Use virtual "perpetual motion machines"  and seawater as energy sources.  The Archimedean screw can offer almost endless energy sources.  "Robert Fludd's 1618 "water screw" perpetual motion machine from a 1660 wood engraving. It is widely credited as the first attempt to describe such a device." (Wikipedia/Perpetual motion) The term "virtual perpetual motion machine" means a machine. That pulls water to the upper tank using a capillary tube. Then that water will fall through the generator or turbine wheel. The machine uses differences in pressure levels. But it looks like a "perpetual motion machine", that is impossible because of laws of thermodynamics.  The machine uses differences in pressure levels. But it looks like a " real perpetual motion machine", which is impossible because of the laws of thermodynamics.  The real perpetual motion machines don't use outside energy. And that's why they are not possible.

Will humans survive the sun's red giant stage?

"As the Sun matures into a Red Giant, the oceans will boil and Earth will become uninhabitable." (The Conversation, The sun won’t die for 5 billion years, so why do humans have only 1 billion years left on Earth?) Sooner or later, all stars use their hydrogen. And then they turn into red giants. Sun is a yellow G spectral class star that turns into a white dwarf. But before that, the sun will turn larger.  The sun turns red and that means. It starts to send more infrared radiation. This thing will turn Earth into a hellish temperature that vaporizes water from Earth.  It's possible. That Earth will also vaporize with Venus and Mercury. Some scientists say that we have only 1 billion years to move farther in the solar system. The habitable zone will go to the distance of Jupiter and Saturn, and maybe humans find a safe place in those distant moons.  It's possible that before Sun will grow too large humans make large groups of mirror satellites or large shields that sho

Metamaterials can change their properties in an electric- or electro-optical field.

"Researchers have created a novel metamaterial that can dynamically tune its shape and properties in real-time, offering unprecedented adaptability for applications in robotics and smart materials. This development bridges the gap between current materials and the adaptability seen in nature, paving the way for the future of adaptive technologies. Credit: UNIST" (ScitechDaily, Metamaterial Magic: Scientists Develop New Material That Can Dynamically Tune Its Shape and Mechanical Properties in Real-Time) Metamaterials can change their properties in an electric- or electro-optical field.  An electro-optical activator can also be an IR state, which means. The metamorphosis in the material can thermally activate.  AI is the ultimate tool for metamaterial research. Metamaterials are nanotechnical- or quantum technical tools that can change their properties, like reflection or state from solid to liquid when the electric or optical effect hits that material. The metamaterial can cru
