Obviously not the Roman Empire, but if we did could we see 2017 from 2018, or 5 mins into the past? Say if it were (theoretically) around the Andromeda galaxy or past the sun?

Hey AskScience! I was just reading about Wollf's law and was wondering if the same thing applied to your muscles?

When anticipating a loud noise, does the body do anything outside of instinctively cover the ears?

Posted: 21 Nov 2015 05:54 AM PST

Is there some sort of mechanism inside of the ears that can reduce sound damage, or are the hands just about it?

Why do falling mortars seem to defy the Doppler effect?

In this video: @0:35, @0:56, @1:24. @2:21 the pitch of the dropping mortars sound lower as they fall closer to the soldiers. What exactly is going on here?

What would be the thickness of a mobius strip?

Posted: 21 Nov 2015 03:20 PM PST

EDIT: I've realized I meant to ask about the width of a mobius strip, not it's thickness

if not, why is gravity unique in this respect, do we even know?

I can't wrap my head around why black holes are supposed to be holes and not, say, spheres the size of a marble or a soccer ball. Don't they have a surface?

This is the article that led to my question:

http://www.cnn.com/2015/11/20/politics/air-force-gunship-lost/index.html

The plane was ok after the maneuver, and even landed ok. What factors lead it to be permanently incapacitated?
