(.#340).- Detect ET's when they roam the galaxy with the energy of a black hole.
Detect aliens as they roam the galaxy with the energy of a black hole.
May 17, 2019.
Advanced extraterrestrial civilizations will inevitably face exponential growth in their energy needs to support a growing population.
They will probably be brought to colonize neighboring planets or asteroids like habitable borders. But where could they connect to get all the energy needed?
As your Guru previously described, they could use Dyson spheres: a common idea that was built around this habitable shell that surrounds a large part of a star and absorbs its energy. But it is a heavy engineering work involving the dismantling of moons or asteroids, which only Darth Vader has presented so far ...
For astrophysicists, the ultimate natural energy cornucopia is a black hole.
This is particularly true of well nourished supermassive black holes. Weighing up to billions of times the mass of our sun, they can shine like lighthouses far across the universe. Their intense gravitational field allows the conversion of their total mass into energy. Their deep gravity well could extract enough energy trapped in a nucleus of popcorn to make a nuclear explosion.
An artificial black hole, in the form of a small battery, could possibly be created by supercivilization.
Louis Crane and Shawn Westmoreland of Kansas State University have calculated that a black hole of a million tons, smaller than the radius of an atom, could be manufactured in a year. In other words, a supercivilization could first build a set of solar collectors with the area of Arizona (295 254 km²) to collect enough energy to make a black hole. The solar panels would power a very large gamma ray laser that would create a sphere of radiation that gains energy from its own gravitation to finally collapse. And hop, a black hole!
An entire asteroid may be needed to build such a "black hole machine", as predicted by science fiction writer Arthur C. Clarke in his novel "Earth, Imperial Planet." "
Once extraterrestrials have built their first black hole, they could improve power generation by using the raw power of the hole to fabricate a number of other parent black holes as additional power plants. The power plant would consist of a spherical shield around the subatomic black hole that would cause thermal engines. Extraterrestrial technology could even find a way to build gamma-ray "solar cells" that feed directly from black hole radiation.
With such power at hand, interstellar travel would become a practical advantage for an adventurous foreign empire. Crane and Westmorland write :
A civilization that is incredibly rich in energy could travel the galaxy at will.
The black hole would not be as dangerous or difficult to handle as a massive amount of antimatter, the fuel commonly prescribed for ship propulsion through space. The confinement of antimatter is a big problem. A leak and everything disappears!
But the black hole is confining itself. What's more, to make a black hole, it takes millions of times less energy than it would take to synthesize and store a comparable amount of antimatter.
There are a number of ways to harness the energy of a subatomic black hole to make a superluminal trip or so. The powerful gamma rays coming out of the black micro-hole could be converted into pairs of electrons and positrons. These particles would be directed by electromagnetic fields in a collimated jet.
The small black hole (for a superluminal journey) should last long enough to accomplish the interstellar mission by preventing it from evaporating, having a mass comparable to that of the ship it propels and being powerful enough to accelerate it so to achieve a reasonable fraction of the speed of light.
The authors reject the viability of another proposed distortion engine based on current physics. An interstellar ramjet that sucks the tenuous hydrogen would produce more resistance than thrust and the propulsion with a laser beam emitted by a host star, comes up against the problem that the beam propagates too quickly.
The authors propose that a meticulous search, by astronomical observations of the sky for gamma rays, could possibly detect the release of these same rays from an extraterrestrial spacecraft. Better still, the black-hole motor emits waves of gravity waves in space-time. As for Dyson's spheres, a detector could be built for SETI (US projects that aim to detect extraterrestrial intelligence signals) to detect only these waves (with wavelengths shorter than the size of the 'an atom).
A positive detection could be a proof of the presence of extraterrestrials, having, of course, put aside the natural cosmic phenomena. But in the absence of a viable physical alternative to perform such detection, we may one day be faced with the realization that we are not the only intelligent life with the ambition to navigate across the galaxy.
