The Fermi Paradox, the ultimate test.
Scientists suggest that all alien civilizations will collapse. Before they reach interstellar flight capacity. That is one of the things that causes big worries. Because we are also one of the civilizations. What makes us different than those still hypothetical aliens, who create a super weapon and then turn it against their own population. This is one of the things. Those are not very often mentioned. This is the thing. Called the final test in the civilization's ability to reach the Kardashev scale 2. The final test is this. The civilization must stop wars before it reaches Kardashev scale 1, which means it can travel in its solar system. The Kardashev scale 2 means that civilization can travel between stars.
The big test is in the case. Where civilization faces some kind of ultimate threat, like a rogue planet. That enters their solar system. They must detonate that planet, or it will cause a lot of destruction. That requires an ability to create antimatter weapons or relativistic ammunition. The relativistic ammunition will be sent through the large linear accelerator. The satellites that go together like LEGOs. And they involve the channel that forms a giant particle accelerator. Or the so-called Gauss track. The RKV ammunition can be. The metal needle that the magnetic system accelerates to a speed. That is about 20-50% of the speed of light.
When that ammunition hits the target, even a large planet will be destroyed. The anti-matter weapon can be a particle accelerator that uses photon-accelerated positrons. Another version is the small magnetic tank, where those positrons can hover. The railgun can shoot that tank against that incoming planet. Those systems are tools. That can turn evil. In the wrong hands. Those superweapons are tools. That power-hungry actors can use as blackmail the entire civilization. The thing that destroys those civilizations is the war against their own colonies. There is a possibility that those colonies.
This civilization uses those colonies. To exploit its solar system’s resources. Can turn rebellious. There can be power-hungry leaders who prosecute their home planet for colonialism. And that can turn this Kardashev scale 1 civilization into a civil war. Another question is this. Can this thing be the end of human civilization? If the ultimate end of civilization is civil war, how can we be an exception? When we talk about things like the costs of interstellar flight, we face the fact that there are always points where the money doesn’t mean.
First, this hypothetical alien civilization might have a different culture. And maybe they don’t care about money. And the point when their star starts to expand is the ultimate final point. Civilization must create ships that take those creatures to other solar systems. Or they will face extinction. The highly advanced civilization can use zombie stars as a power source. They must only drive material to the white dwarfs or the neutron star’s shell. But they must survive the supernova or nova eruption. That can be very violent. The question is always this.
Can we avoid that situation? Well, the fact is this: sooner or later, our Sun will expand into a red giant. In this case, the sun will destroy our planet. If our descendants exist. They must move away, or the red giant burns them in an inferno that we cannot even imagine. When the sun uses its fuel. That star known as the Sun explodes as a nova. The result is a white dwarf. Maybe. Our descendants can create space stations. that can survive that event. And then they can start to drive material, like ions, to the white dwarf shell. Or they can create lots of solar sails and send those crafts to the galaxy using the nova eruption as a booster.
When we talk about things like generation ships. We face one. Very big assumption. We always think. Those crews that travel with those slow spaceships are sent by a civilization that waits for them to return. The thing is that there is a possibility that those crews left from the solar systems that were destroyed a long time ago. That means those ships might have left their solar system in the final moment. And that means there might be nothing waiting for those crews. That is one hypothesis that should make us afraid.
