Nah, there are some conflicting ideas to suggest that humanity needs to perfect itself socially first. Instead of exporting all of our problems to space.
I'm on the boat for space but perhaps the most efficient strategy would be to do both.
If anyone is curious, the exploration through which we would find other planets and map the galaxy is theorised to be through the use of robots.
You send out 100 robots, each of them programmed to find a planet, land, and then create a centre to develop 100 more robots (Obviously the numbers will be different of course, probably closer to the thousands or millions). The robots will find the planet, send back data to the HUB, whether that is Earth or the earthling's favourite colony/space station.
Then they build the new robots and send them out to all their own planets to repeat the process.
Then BOOM, map of galaxies. Human search teams will be highly unlikely except for immediate landing parties to set up colonies or anything.
Or so I've learned from Michio Kaku's theories, there will of course be other ones so his shouldn't be considered the only possible solution.
But, if you're interested in physics, Michio Kaku's books and speeches are a really great place to learn and they make it accessible to mostly anyone.
Damn... I sound like an ad...
That's all!
