(12,072 posts)Let's suppose that such travel is possible. Given the size of the galaxy, somebody has already discoved it. That civilization will also know that their parent star will one day die - as all stars do. Further, they will be an exploring type species as a species with no exploring genes will never make such discoveries. They will explore and start colonies on other planets. As those colonies mature they will also send out other exploration missions to still more planets, while the original planet will continue to explore.
They won't fight interstellar wars as that is just too expensive. The logistics are just too great for that.
They won't lose or forget about colonies as they will have advanced record keeping as part of being an advanced civilization.
If they can go from colony to mature civilization in 500 years, they their number of colonized planets will double every 500 years. In a couple of hundred thousand years - an eyeblink in cosmological time - they will have found and colonized every planet in the galaxy. And every such planet will be part of the galactic civilization.
Look around. Earth has been a prime planet, ready for colonization since a few hundred million years ago. They would certainly discoved us and already colonized us before the dinosaurs. Are we part of such a super-civilization? Nope. Therefore, such a space-faring civilization does not exist.
Other technological civilizations may exist, but they are limited too.
