Well a extreemly lot of stars and beyond that a extreemly lot of galacy's and beyond that no clue.Question: What eerie things do you think lie beyond the fringes of our solar system and galaxy? Life? Emptiness? Remnants? Something else entirely?
Aliens well lighst speed is getting to slow within our solar system. Mars is in reach if a year or 2 aren't a problem. But out there so many stars.
If chance life spawning with a few right conditions there would be lot one cell life out there. If stars with a planet with such condition are 1 in a 10.000 there are a whole lotta places where life can spawn. And evolve to something a lot more advance who drive technology further for whole lot of 1000 years. And these species might have a long life cycle to depelop there personal knowledge.
But then again FTL might be just not possible. Or FTL capable aliens a very rare thing.
Aliens are just isolated due to the limit of no FTL posible.
We can reach a next star. with sublight.
We need to find and garther a whole comunity with a large enough gene pool to start a kollony. With a mother ship where many generation can life there life, until they get there.
The resources are massive. And the fully backup form whole earth society is needed.
The ship and resources must be build and mined in space. Moon mining Mars mining.
So probaly feasable. But far fetched. To much hurdles to overcome. To get earth autorities on the same wave length.
First hurdle is a moonbase kolony wich do mining and space travel industral things.
Traveling in the future is already done. There is a astronaut who is 15msec younger
Well we know stars because we can see them. But I expect a whole lotta flavors of planets. There might be more planets then there are stars. We are aware that a several hundred exist. But are detected inderectly.
I don't expect a alien nation on the closest star. But it might be nr 879nth star 155 LY away or so.
I won't expect life in the galacy center or where novae or gammaray burst went off. That sterrilise the region. So could be there are Alien relics out there because of these fenomenae.
And wenn we do meet aliens here. This would mean they are lot more advanced to get here. Or put all there resources to it. Wich means they won't go back. And came for something. Food? And are carnivoric like. And like we humans kill each other so easy. A Aliens vs Human thing would be a nobrainer. There are astrophysics who warn for this. Like Japan fish industrie sees inteligent dolphins as food.
Maybe it's a good thing No FTL isolate species betweens tars.
