No one can hear you scream in space. They can’t hear you laugh or cough or clap your hands, either.
Sound is defined as vibrations that travel through a gas, liquid, or solid (e.g. the floor of the apartment upstairs) that is heard when those vibrations “shake” the eardrum of a person or animal.
So despite the loud booms of spacecraft exploding in movies, explosions in space are silent. However, secondary sound effects may be heard. Debris striking a hull or window of a spacecraft might cause a vibration inside that generates sound. Astronauts onboard the Space Shuttle reported hearing loud bangs as the metal structure of the vehicle shook during jet firings. A spacewalker banging on the hatch could be heard by those inside. Would touching helmets together work? Probably not much, considering the thickness of the glass, but combined with lip reading, it might help!

I am phasing out MailChimp because the format is too time-consuming and has a rather low limit on the number of emails I can send. I'll keep sending Science Snacks to those of you who are subscribed at least until the end of this year
, but I won't be adding more subscribers via MailChimp. Instead, I will encourage interested folks to sign up via WordPress, jump to the blog through my website (MarianneDyson.com) Science Snacks Blog tab, or be notified via links I post through Twitter/FaceBook/LinkedIn/Goodreads and especially my Amazon Author page
which anyone with an Amazon account can follow. So please follow me on Amazon
