A lot of people smarter than me think it is supported by MWI. Max Tegmark, for example wrote about this in Our Mathematical Universe[1]. No "teleportation" is required, you simply aren't observing the universes in which you die. So there is a selection bias. 1. https://en.wikipedia.org/wiki/Quantum_suicide_and_immortality#Thought_experiment https://en.wikipedia.org/wiki/Quantum_suicide_and_immortalit... edit: Note that I do not agree - as some do - that you can extrapolate from this that MWI means we are all immortal. The "continuous fade" argument made by Tegmark is quite convincing, as are other objections to this idea.
