[Star Wars]How long would Palpatine be falling for after Vader threw him down the death star shaft.

For extra context It is the equivalent of falling down a hole dug through a moon that was 160 km in diameter. I believe the shaft went all the way to the center of the death star.

Given that there was some kind of explosion visable a few seconds after he fell in at which time his screaming stopped, its safe to say the shaft isn't empty.

So he hit whatever is in it, probably exhaust gases, and wouldn't make it all the way to the bottom.
