Just a final thought to wrap up this series of posts reflecting on some theological implications of the new physics: as I mentioned, one implication of the Many Worlds Interpretation appears to be that of eternal life. The concept of Quantum Suicide suggests that at each ‘quantum moment’ I might die in one universe – but remain alive in another, and this process continues ad infinitum.
It struck me today that this same idea could be applied morally too. At each moment of decision, thought or action, the Many Worlds Interpretation suggests that a quantum split occurs for each possible outcome. In one universe I think that terrible thought; in another I don’t.
So in amongst this near-infinity of parallel universes there exists, according to the MWI, a universe in which I have made all the right decisions, thought all the purest thoughts and acted in the most gracious and loving way. Indeed, if this is true, theoretically there will exist one parallel universe in which we have all done so.
It is the Quantum Heaven. It is not this universe. And there may be no dogs there.
