My understanding from all of this is that the rope is rocket-powered to
get to the lounge, not to go away from it. That would even help with that
whole problem of the rope being able to continue “downward” through the
explosive decompression.

Actually, even if there wasn’t any artificial gravity, the fact that the rope
going back to Lafiel’s ship at such a great speed would give them a great
amount of whiplash.
|
The explosive decompression through the newfound hole in the canopy would
provide a large assist in breaking them free of any localized artificial
gravity, which should end somewhere just within the space contained by the
broken canopy (after all, you don’t want to collect random space junk all over
the pretty window, do you?).
Whiplash is caused by having your head bobble back and forth or side to
side, not by being pushed downward, or against anything that can help resist
the whole bobblehead effect (it should be noted that naval aircraft carriers
use afterburner backwash and a high-speed cable launcher to essentially fling
aircraft off the deck fast enough to cause the pilots to black out for a brief
amount of time as their blood tries to reorient itself, and the pilots don’t
get whiplash). As long as they weren’t being stupid and gawking upwards when
the rope starts getting reeled in, it wouldn’t be so bad. The best thing to
do would be to grab on immediately opposite each other, and tuck both of your
heads forward to brace against the other person’s shoulder. And hope he
doesn’t lose his grip.

I see. And they had their eyes really shut and their heads were at regular
level.

It’d be like grabbing the leash of a dog as it runs past you. A really,
|
Not really. First of all, the rocket on the rope should be holding it
down in the room against the rush of escaping air, so they’ve got a bit of
time to grab onto it. Second, if the winch system is allowed to ramp up to
speed instead of instantly kicking into overdrive, the relative G-forces of
being hauled out of that room should be relatively low. The big question is
if the rocket was kind enough to shut off just before they grabbed on, so it
wouldn’t be toasting their feet through the entire ride.
|
It was shut off before it was wound in.
| |
| |
The physics of it all really seem iffy
|
I’m not saying that it’s probable, just that it’s minutely possible.
Odds are something would go horribly awry, and at least one of the escapees
(most likely both) would end up dying an unpleasant death.
|
Right.
| |
Indeed it is, and these preposterous storylines are one of the three main
reasons why I rarely ever watch anime (the other two are the silly
conventions, like giant eyes = good guy, and the reduction in animation
quality caused by too many budget constraints, like speed lines being used to
convey the idea of motion because they can’t afford to draw buildings).

Where else does constant thrust equal constant velocity in zero-gravity
|
I could be wrong, but I was always under the impression that Star Wars
invented that concept.
| |
and items bulge before exploding?
|
Eh...not Star Wars. But that one Treehouse of Horrors ep of The Simpsons
does show Homer and Bart getting some serious big-head syndrome before popping
offscreen.
|
Yeah...but the zero pressure can make your eyes pop out and stuff like that
after a while.
Thanks and PLMKWYT about the subject.
Cheers (*clink*)
