It Is time for the Pentagon to Ufos seriously?
After a seemingly credible military encounters with Ufo’s, why not in the Pentagon care? #Tucker
How to dominate the universe in three simple steps…
Step 1: Harvesting your planet’s resources.
Step 2: the Harvest of all your nearest star-energy.
Step 3: Harvest the energy of all the stars in your local galaxy, then move on to another galaxy.
Congratulations! Your species now has all the elbow room it needs to grow into a universal superpower.
That is a Russian astronomer perspective, anyway. Astrophysicist Nikolai Kardashev first proposed these three phases (the so-called Level I, II and III), of the galactic expansion, which he referred to as the three “types” of technologically advanced civilizations in 1962 as a measure for the power consumption of more powerful societies. Recently a paper published June 13, to the preprint journal arXiv.org is revived Kardashev’s model and a new, apocalyptic touch. [13 Ways to Hunt Intelligent aliens]
According to the author of the paper Hooper, senior scientist at the Fermi National Accelerator Laboratory in Illinois and a professor in astronomy and astrophysics at the University of Chicago, harvesting energy from distant stars is not only the best way to a civilization available resources, it is also the only way to avoid the ever-expanding universe of the left of that civilization all alone in the vastness of space.
“The presence of dark energy in the universe is the cause of space to expandat a pace,” Hooper wrote in the new paper. The next 100 billion years, the stars in our Local Group, or a group of gravitationally bound galaxies that contains the Milky way, fall outside the cosmic horizon, which means that an observer here would never be able to get information from them in the course of the age of the universe.
At that point, “the stars are not only unobservable, but totally inaccessible, so how much energy can be won,” Hooper wrote in the newspaper.
In other words, if people hope to meet the aliens in distant galaxies, it will be a race against the dark energy — that mysterious force thought to be the uncontrolled stretching our universe farther and farther apart.
The capture of a star by the toe
That is, of course, how do we find the aliens.
An advanced civilization worth their spaceships would understand the stark reality of the universal expansion, Hooper wrote, and they would not sit on a chair idly while the universe literally passed them by: They would catch the stars in other galaxies, wash them and harvest their energy in the first place, for those stars (and their energy) was inaccessible forever. [12 Possible Reason is that We Haven’t Found Aliens]
“Given the inevitability of the encroaching horizon, any sufficiently advanced civilization that is determined to maximize the opportunity to make use of the energy will expand throughout the universe, attempting to secure as many stars as possible before they are permanently inaccessible,” Hooper wrote.
So, how does one lasso a star in the first place? Scientists and science fiction authors have thought about this question for decades, and their favorite answer is this: Throw a giant net around, of course.
This net would not be made of rope or even metal, but of satellites — a swarm of millions of solar-powered satellites known as “Dyson spheres.” Such a colossal cloud of harvesters can permanently float around a star, radiating energy back to a nearby planet or, Hooper presented in his new paper, actually use the star energy to accelerate the entire ball of fire back in the direction of the planet that wanted to use it.
This may seem like a tall order for humans, who are still bumbling around level 1 of Kardashev’s scale (Carl Sagan placed approximately 0.7 in 1973). But some scientists think that there could be alien civilizations of thousands or even millions of years older than ours, which is already far in their level III, star-harvest phase.
And if another civilization is indeed started with the redesigning of the star, it may not be long before the Earthlings in the holes, Hooper wrote.
“Those stars that are currently on the way to the center of civilization could be seen as a consequence of the propulsion that they are currently undergoing,” Hooper wrote. “Such an acceleration would be necessary to use large amounts of energy and likely to have a significant fluxes of electromagnetic radiation.”
The refurbishing of the galaxy
Then watching all those stars will be dragged unceremoniously across distant galaxies, astronomers could also keep an eye out for the special galaxies that have had their prime stars ripped away from them, Hooper wrote.
This hypothetical, star-harvesting aliens will probably be picky, Hooper noted: tiny star, hundreds of times smaller than the Earth, the sun, would not produce enough radiation to be useful; significantly larger stars, on the other hand, would probably be too close to going supernova to be used as a viable battery. Only stars with a mass of approximately 20 to 100 times the mass of our sun would be viable candidates for capturing and conveying back to the home galaxy, Hooper said. And because solar objects in that mass range radiate certain wavelengths of light more than others, alien, star harvest would appear in the light of the signatures of these galaxies.
“The spectrum of starlight from a galaxy which is the useful stars harvested by an advanced civilization would be dominated by massive stars and thus peak at longer wavelengths than otherwise would have been the case,” Hooper said.
The man is probably not accurate enough instruments to detect these unusual light signatures, beaming from the depths of the universe, Hooper wrote. Hopefully, astronomers will develop, before the sun is a flaming marble in a far-off civilization of the collection.
