If i drop two objects, does everyone agree they land at the same time?
Special relativity tells us simultaneity is relative. So if I drop a hammer and a feather on the Moon, could an observer in a rocket see them land at different times?

In a uniform gravitational field, all local observers in that frame see the same simultaneous impact. This is actually a consequence of the Equivalence Principle: gravity and acceleration are locally indistinguishable. The relativity of simultaneity applies to observers in relative inertial motion in flat spacetime. Here, everyone shares the same accelerated frame. Their clocks tick at the same rate relative to the event. Simultaneity isn't relative in this case it's locked in by the shared gravitational field.
