Cheap Astronomy - Implausible Engineering Episode 1: How To Live Longer & Talk To Aliens

The 365 Days of Astronomy

Hosted by Steve Nerlich.

Episode 1a: The Relativity Vault

We’re all going to die. But let’s say you’re going to die from some incurable disease – or even just from

ageing – and you’ve got some time to plan ahead. One option is to assume that future science could

save you. A common strategy to access this option is to get yourself frozen – or even just get your head

frozen –until medical science can find a cure for whatever ails you.

Episode 1b: The welcome note

One solution to Fermi’s paradox – about why there’s a universe of potentially habitable worlds out

there, but no-one’s talking - is that we are the first, or at least one of the first technology-exploiting

species. After all, it’s unlikely much could have happened when the early Universe full of hydrogen,

helium and a few trace elements – you need stellar nucleosynthesis to build more complex elements

and supernovae to spread those elements out.
