Typically, you can expect a star to pass through (or near) the Oort Cloud every hundred thousand years. Very close flybys (like within 52,000 AU, happen more rarely—about every nine million years. So, it’s a fairly regular occurrence in the long history of the Solar System.

A short hop and skip away for a technically advanced relativistic civ. With its head pulled out of its collective asses, unlike ours, lol.
Humans have been throwing spears pretty long and some of our not so "human" ancestors also tool used FYI. There's proofs. I mention this to point out that tool use isn't all that special or unique or hard. Our ancestors could definitely have come into contact with extrasolar bros too. That could definitely have spurred our development from simply spear throwers, into giant metal rocket spear throwers. Too.
You don't even need fancy generational ships to colonize a galaxy over a 100,000 million year span. Just float around stars hitching free rides until they come close enough for a decades long short jaunt.
Anyway the article is a very cool read. Gud science.
