Within the vastness of the Universe, humanity is not that big of a deal. We're not here because we're meant to be here, we're just... here. If mathematical predictions are correct, we might only have 760 years left. What would be the cause of our extinction? What would we do if we knew exactly when our existence will come to an end? Could we delay the inevitable?
