Well, not really, but that’s the premise of this thread.
If you want to argue that it can’t happen or we’d never find it or whatever, feel free to start a thread and I’ll drop in for a visit.
In the past few decades we’ve gone from theorizing that planets exist outside our system to seeing gas giants, to currently locating a solid, if inhospitable world.
It’s now 10 years in the future and our astronomers have found a planet smack in the middle of the temperate zone of a distant star. Gas spectography determines that there is water and chlorophyll analog plant life. The only thing needed to be 100% certain is a postcard saying Wish You Were Here.
Obviously we’re not likely to get there any time this century without whole new branches of math, science, and physics.
So what will our reactions be and what will we actually do in the meantime.
There will of course be the usual collection of CTs who’ll claim that it’s all faked.
Ditto some of the mainstream and minor religions.
There will be the groups that want to put together collections of every type of transmitter we have to beam “Hi neighbor!” messages at it.
And the other end with the isolationists who are worried that the neighbors are hostile and have figured out FTL travel.
As for myself, a bit more moderate, we’ll build space based all-spectrum telescopes that will make Hubble seem like a highschool science project. Take a closer look at it and the rest of our neighbors.
Beyond that, nothing will really change until someone comes up with a viable way to visit.
