Since the speed of light is measured with time what affect does slowing down time have on the speed of light? :eek:

Speed is measured in seconds, minutes and hours? :think:

How is the speed of light affected by slowing down time? (Better? :D)

There are no stationary observers.

In other words doing nothing other than pouring oxygenated liquid directly into a lung (as shown in the movie) can not and never will be a functioning oxygen/carbon-dioxide exchange system. The subject in question would drown.


EDIT: Hang about. A special suit is used in the movie isn't it? I guess a membrane oxygenator could be incorporated into the suit ... but then blood would need to pass intravenously from the suit into the body, so certainly not as described in the movie where the implication given is that the lung itself 'breathes' the liquid. Hm.

18 hours is not that short :) And that was the 60s.

Due to the principle of relativity, every observer may be described as being stationary (and that's why time dilatation comes into play).

Eh?

Lois Lane is the stationary observer. Or earth. Or everyone on earth. However you want to look at.

Stationary relative to Superman and his Super-light speed.

Wow. Well I was 100% wrong in that case. Alveoli can exchange oxygen & CO2 with an oxygenated liquid. :)

I'll find an easier target to pick on than The Abyss then. :sour:

In Superman II, or is it III, Lois Lane is in a car which is crushed during some earthquake or summink caused be Lex Luthor. She dies.

But I guess any limits imposed on us by our physical universe are mere hurdles to overcome for our Superhero. Cos he's Super. :rolleyes:

That was Superman. The first movie everyone loved. :down:
