Earth is gone. Complements of some natural occurrence, you name it, perhaps a rouge primordial black hole that happens to be passing through our solar system which then sends the earth into direct collision with Jupiter. Or perhaps there is a giga-solar flare which perturbs earth’s orbit sending it careening into the sun. Result? All that you and I and your pet salamander were, every cell and every DNA molecule, every atom that was on or in the earth is now ionized nuclear fuel within the sun. The Darwinian evolved chemistry and biology that many fall back upon to describe life, particularly human life, on earth has ceased to exist in this solar system along with its thermodynamically described, Gibbs-free energy processes once used to represent the entirety of earth life. Additionally, imagine if you will that there is life elsewhere in this universe. Let us imagine there exists at least one other evolved ecosystem (ECO-2) capable of hosting Darwinian life. Different from earth but governed by the same laws of physics and biology and thermodynamic processes that manifested earth’s ecology. This planet orbiting a viable star may be located anywhere in this universe since the laws of physics are expected to be consistently applied throughout. Also for this anecdote let us say that this other bastion of life is some 10 billion light-years from earth’s sun. A distance so vast it would take much longer than the age of the big-bang to relativistically travel that distance, assuming, of course, there were any classically defined remnants of one’s biology left to make the journey.
