If you think we have problems now, just wait a few billion years, when the accelerating expansion of the Universe triggers an energy crisis of cosmological proportions. Sounds grim, but as a new paper points out, an advanced civilization faced with doom won’t have to go gently into that good night—there may very well be a way to rage against the dying of the light.

Owing to the inexorable influence of dark energy, the space in our Universe is expanding at an accelerating rate. We don’t need to worry about this right now, but for those civilizations still around tens of billions of years from now, it’ll probably be a major headache. By this stage, galaxies outside of our Local Group—a conglomeration of about 54 nearby galaxies—will be moving away from us faster than their light can reach us, making them completely inobservable, and by consequence, utterly inaccessible.
