Ah, Internet questions. Where would everyone be without them? Most likely everyone would get a lot more shit done. But hey, they're fun. Like this question: Could a feather kill you? Reddit asked, and this video answered.
The idea here is that a feather could potentially be damaging without the Earth's atmosphere getting involved. Without the atmosphere, both a hammer and a feather would fall at the same rate. So, if that feather were dropped from far enough away, could the force do some serious damage to the hypothetical person standing underneath it?
Luckily, YouTube channel Brass Tacks provided an answer. That answer is, yes. But it's complicated. Watch the video and check out the math in the description. It's legit.
