Maybe a copy of other blog articles:
My
favourite film is 'Passengers' not just for the 2 main characters, but
that it covers the fact that complex real-world systems breakdown
(often!) and that On Board Spares & Repairs facilities, let alone
obsolescence issues, and save magical matter replicators/3Dprinters for
Line Replacement units, would be required & the engineering involved
to bring systems back to 100%
Btw
that's why I think InterStellar Travel will never be achieved by any
possible civilisations, we don't see any even probes despite SETI (I
crunched many WU's as did colleagues, some used to some still do work at
the local Jodrell Bank 76m famous Radio Telescope) sorry to burst
Sci-Fi fans bubbles, despite the huge provisioning, distances, time
required. Star Trek is responsible for many assumptions, immensly
enjoyable but engineeringly impossible, we even got the engineering book
of the series, great fun!
(Oh
whilst I'm on my 'SoapBox' I think it likely, as per fellow Physics
ManchesterUKUniversity Alumni Prof Cox, we are the only local Star
system species in this MW galaxy at the moment, or maybe ever as per
TIMC radio series on BBC the chances of us existing as this techno
species is 10^24 whereas MW star Nos are 4x10^11 at most & our G2V
type star is not that common.)
