So, here's the thing... the calculations for things like freefall distance are pretty straightforward.
Burnham rolled out of an open doorway and fell for ~4.5 seconds onto the roof of a passing turbolift. Assuming
Discovery has Earth-like gravity, she'd have fallen ~99m and reached a speed of ~158km/s. Apparently she sutained no life-threatening injuries while doing this, thereby revealing that Burnham is secretly a Jedi.
Later on, we see
Discovery's warp core fall for ~8 seconds (although admittedly it scrapes the sides on the way down, because... yeah... why would you want a smooth ejection system for a warp core, I guess

). Assuming it fell under gravity, it has travelled ~300m
before it leaves the ship.
Discovery, based on its canonical length of 750.5m, is only ~75m tall.
Never mind the cavernous open spaces we are somehow expected to believe fit
inside the ship.
Even if we assume everyone and everything was falling very slowly, the ship is shown to be
impossibly big.
Spacedock big.
TARDIS big. It's farcical. It's impossible to take seriously.
