Although i enjoyed the film very much i guess there are some major holes physics wide. The aliens seem to float. This requires a much more dense atmosphere than that on earth. When Mala is taken to the spaceship she is still able to float , on conditions that should be closer to earth for humans to live.
There are some major holes in your conclusions argument-wise, because you allowed yourself to accept "aliens-as-another-race-of-humans" pre-sumption-- which is not really a given, except in sci-fi soap/space opera.
E.g. When the aliens float you immediately conclude that their atmosphere is much denser then earth atmosphere-- because you assume that a "normal" alien would have the mass/density of a human?
IOW, the logical conclusion to the aliens being able to float on Terra and on the Ark is that their density is similar or lesser than the atmosphere on Terra and on the Ark-- which is part of the mechanics of how fish and mammals on earth are able to swim under water.
There is no (sci-fi) explanation as to why they would have such a low density, but it may something to do with them being some kind of Helium breathers (as suggested by the director)-- and since having an air-swimming or Helium-breathing species of aliens is simply part of the plot premise for Terra, it doesn't really constitute a "plot-hole."
BTW, a better "plot-hole" would be Mala falling to the ground when she ejects from the human space-ship, since she is able to swim in Terran atmosphere-- but it could just be the momentum of the hurtling human space-ship that she gained while she was in it.

I have to admit that you are right. It seem that i jumped to the conclusion without checking all the variables.
So the atmospheric pressure and gravity on the 2 planets is similar and the aliens mass is lighter than humans. I was thinking the opposite :)
Thanks

Your Welcome.
Personally, my biggest gripe or "plot-hole" is how a Terran gas mask could allow Mala breathe the atmosphere on the Ark, when the Terran had no experience with "human" atmosphere.... unless the Ark was already "harvesting" the Terran atmosphere from below (see Mala's Trap) and merely "refined" it for the Ark (with the Terraformer technology)?
But that's about as far as I go-- Battle for Terra is clearly soft sci-fi and the gas-masks were simply sci-fi gimmicks to help the story along.....
But then there is Mala's father who seemed to have survived without wearing a gas-mask on the Ark-- which could count as a goof, or just the fact that the humans had left him for dead/to die.

The father had what looked to be tubes in his nostrils, much like oxygen tubes that people have, so the tubes could have been full of the Terran gas.

Totally agree. Maybe the aliens weight only 1 kg with a extremely low density (a totally diverse evolution, who knows?) And every single cell in their body is filled with Helium. Therefore, they can still barely “float” in human’s space-ship.
Well, of course, there are details that cannot be explained. Maybe the "low budget production" is a better explanation.
