No wonder the Millennium Falcon takes so longer to calculate its jump to hyperspace.
Tens of thousands a year is one an hour!
There are so many supernovae you really could bounce too close to one and that would end your trip real quick
Star Wars takes place entirely within one galaxy, and the number of supernova per galaxy is something like 1 per century, so, nah, Han was just bullshitting to stall for time while his busted-ass computer cobbled together numbers.
Most movies don't even leave our stellar vicinity, because they want to use hyped star/constellation names and these are from the very local set of stars. Not only a naked eye sees only around a few thousands stars, but most of them are basically next door. The mean distance to the star that you can see is <1% of galaxy size. Almost everything you see is in a 10px circle on the 1080p fullscreen galaxy map.
Not only that, it happened a long long time ago. I'm no astronomer; would that be more or less supernovae?
Indeed. They didn't say it happened an "int" time ago. They didn't even say a "long" time ago. They said a "long long" time. I'd have to pull up a copy of the C standard to be sure, but even if the units of "time" are plank times, I suspect the implications could easily be that the story occurs before the big bang.
I suspect you're thinking of a double (floating point). A long long is only a 64 bit integer.
2^64 planck times is 9.9e-25 seconds. Planck times are really tiny.
2^64 nanoseconds is 584 years.
