We often think that one day the world will come to an end and humanity with it, and possibly with us causing it, but what would our world be like if life persisted after humanity was gone?

Aliens Beyond the Galactic Rim?
Worlds far from the Galactic Core are thought to be low in many important elements for life, but some new research calls that into doubt, indicating that the ancient old worlds of the galactic rim might harbor alien life.

Artificial Afterlives
For as long as we have had history and likely before, people have contemplated a life after this one, but might we one day create artificial afterlives? And if so, will we create heavens or hells?

Many believe civilizations which survive the challenges of technology will inevitability build Dyson Spheres encompassing their entire sun. So how do we find these megastructures if they exist?
