How do 2 objects of different weights fall and touch the ground at the same speed and time?

Question

Imagine 2 objects, 1 is a 50kg dumbbell and 1 is a 1g feather, how is it possible that they will fall and touch the ground at the same speed and time assuming they are dropped from the same height?

I must be understanding this completely wrong.

Edit: I definitely understood it completely wrong because I did not know it only applied to objects in space. That makes much more sense.

Answer 1

One way to imagine why they can’t fall at different speeds is to imagine a small thing tied to a big thing. The small thing would fall slower and hold back the big thing that wants to fall faster, but also a small thing tied to a big thing is an even bigger thing that should fall even faster. The only way the whole thing works is if the small thing falls at the same speed as the big thing and the even bigger thing
