sorry to bring back real life physics into this but... just no

water resistance is orders of magnitude higher than air, this is why irl, you can conceivably protect yourself from bullets by being submerged a short depth in water

Your physics knowledge is woefully inadequate; at 0.01% the speed of light, the difference between pushing through air and pushing through water are negligible. Both would be massively destructive to the ship and the medium traversed. TLJ shows us that the ship accelerates to near-lightspeed before going into hyperspace. Rogue One shows us you can go into hyperspace from within an atmosphere. The two together do not make sense.

no it's not

water resistance is orders of magnitude greater than air, which means that at 0.01% the speed of light, pushing through water is orders of magnitude harder than pushing through air

I agree both are extremely destructive but saying the difference is negligible is like saying the difference between running into a wall of feathers and running into a wall of bricks is negligible

edit: to clarify: drag is proportional to volumic mass of the medium, volumic mass of water = 1000 x volumic mass of air (roughly)...

Run into wall of bricks at 0.01c and what happens?

Run into wall of feathers at 0.01c and what happens?

The difference is negligible.

the difference is that shields that might endure air drag as seen in the movies might be a tad strained enduring water drag which is 1000 times higher

there's a reason irl you can still fall through the air at terminal velocity but faceplant on water as if it was a concrete wall once you reach it

And spacecraft hitting atmosphere at the wrong angle & speed splat too. If that speed is anything like 0.01c, air would be impenetrable.

except that the movies showed that hitting atmosphere in lightspeed is possible due to shields

but drag in water is 1000 times higher, hitting that is a whole order of magnitude that the shields might not bear, their breaking point will come 1000 times faster

You tried arguing "real physics" and failed. I won't argue what's shown on screen even though I find that it is idiotic when physics are considered. However, if accepted as possible, then it is idiotic to assume that physics somehow start applying only when wet.

I have referenced the actual fluid mechanics equations, which you conveniently ignore to support your point

even if it's movies physics, there are rules, if drag wasn't an issue for shields, people in the movies wouldn't be afraid of going through stellar objects in lightspeed, they would ignore it

but you obviously ignore that

And you ignore that the new films basically show us that no rules really apply. But don't worry, I suffer such people gladly...this week.

ah, the old "my brain functions at a higher level defense" to deflect any argument and logic that undermines your point...

I can see nothing will get through, nevermind then
