A bazillion points to everyone!!...
Ex-Minion, yes the sun is indeedie our nearest star...Named Sol by scientists as it happens...Oddly enough, it's Latin for sun...But anyways...Yes, well done that man and his maths...
Impy!!...Yes, the sun is a long long way away...93 million miles, give or take a few...And well done for knowing that the Alpha Centauri star system to ours...Made up of three stars...Named, boringly enough, A, B and C...C is also called
Proxima Centauri which is the nearest star to ours...
Everyone else, but most espescially Ghastley...Nice one!!...
Yes, Ghastley's right about all the nasty maths and time dilation effects etc and yes, I meant subjective time from Earth of my travelling 4.24 light-years there and back (as a straight round trip) would be about 9 hours...
Though I do take issue with the scientists who insist on this quantum effect thing...A light particle still has to travel the distance the 4.24 light-years actually
is, and therefore,
you, as an observer on a craft travelling at said speed would be aware of time passing...Stands to reason...But they're the clever ones with letters and stuff around their name and I milk cows, so - as a wise man once observed - I know my place...

Aaamywho...
Hi! I'm Sam Beckett, lead character in TVs old show, Quantum Leap...Where each week, by way of Super Science and Plot Contrivance, my soul essence would possess the body of some unsuspecting person in any year that my character had been alive and "Help them" in some way...Be it protecting Jackie Onassis or helping Buddy Holly with the lyrics to Peggy Sue...
Help! Something has gone wrong with the machine and I seem to have been transported to England in the 1500s...I seem to be inside a ginger fat dude with a penchant for offing his wives...
Who am I?...
