It’s a first contact story that suggests most species in the galaxy develop an anti-gravity/ftl technology incredibly early, and so they end up colonizing the stars without ever developing beyond 15th century tech

We Could Build a Skyhook Now

Watched 1,000km Cable to the Stars – The Skyhook by Kurzgesagt – In a Nutshell from youtu.be

Getting to space is incredibly hard, expensive and needs a lot of resources. A more efficient way to get there is a Skyhook (or Spacetether), an ever rotating cable with a counter weight, that catapults spaceships from earth orbit into the depths of space.

Apparently we have the technical knowledge to build a skyhook today??? Can we get on that?

As a sci-fi writer I feel some distress that I was born too soon to see real space exploration. I hope to see advances in my lifetime.

I have to chuckle because of course I chose a space elevator (which is not currently technically feasible) for my (on hold) space opera. I needed it for plot reasons 🤷‍♀️
