Sorry, but you're wrong here. There is no way to distinguish velocity in space - but it is certainly possible to distinguish acceleration. And, when a spaceship banks, it is simultaneously reducing its forward velocity while increasing its sideways velocity - acceleration in two dimensions. This would be noticeable to any inhabitants, in exactly the same way that you notice when a car/train goes around a bend. :prof:
That's a maffs joke, ain't it?

Okay, fine, I'll tell you if you insist! :prof:

The giant chunks of the blown "ice cap" SINK onto the secret lair, and onto the Joes in their tiny submarine "fighters."

Um...ice floats last time I checked...unless it's methane ice.

I'm surprised nobody figured that out...you're all so smart. :biggrin:

I can't be assed to read through the thread, but has anybody mentioned loud explosions in the void of space?

I think this was mentioned a couple of times way back at the start of this thread...

But that would wreck my head too.

Good thing I've not seen that movie.

Anyone else thought the makers of the Ice Age films had some agenda? That whole thing about the Dodos becoming extinct because they're too stupid wound me up something terrible. :twitch:

The Millennium Falcon did not have the capacity nor mass to install or use FTL engines and thus could not do the Kessel Run at all, not to mention the fact it would have been torn apart in the Black Hole Cluster's gravitational madness. Secondly considering the number of impressive prime predators on Naboo, I highly doubt the Gungan, a species which prize Jar Jar Binks as intelligent would have continued it's evolution to that state.


Also, Spock doesn't seem to know what logic is.

You mean great flaming explosions caused by very tiny explosive charges?

It's not his fault, - he's half human, half Vulcan. I'm not sure if they ever gave an explanation as to how that was genetically possible though. :ask:

Nope. The ship creates its own gravity effect so any external effect would be compensated for to maintain a seemingly static environment. They all ready thought of this :hmph:

They even account for the shaking and jerking seen in battle scenes to heighten the sense of urgency by saying that the artificial gravity field is imperfect, so some small effects may leak through. One of the most common things in good science fiction writing is to deal with inertia effects imperfectly, in order to limit the capabilities of the spacecraft to allow plot points in battle scenes.

In the "Skylark of Space" series by E.E.Smith, his spacecraft completely eliminated inertia inside the field effect, so his spacecraft could change direction instantly, going from superluminal speed to zero in nothing flat.

That depends upon whether the artificial gravity in the ship nullifies all other forces upon it or is additive with them. In the latter case, acceleration effects would still be noticeable. :tea:

More interesting is exactly how the ship "creates its own gravity" - something which is glossed over in many sci-fi stories...
