Madara nearly died lmao , he himself admitted that.
And speed keeps on increasing when you fall with the Acceleration of 9.8m/s².
So,
Speed at impact:442.72 m/s
or1593.79 km/h
Time until impact:45.18 s
Energy at impact:9800000.00 joules
So unless Might guy was producing energy of that much , Madara dies.
