19. There’s Sound in Space
Sci-Fi fans often believe that there is sound in space thanks to all the larger-than-life heroes and villains that are spotted onscreen. Here’s the spoiler- because space as we know it does not have an atmosphere, sound waves simply do not travel through at all.
So, even an explosion would most likely not be heard at all irrespective of where it occured. Other planets however for example Mars do have an atmosphere and sound is audible there. With one difference, however- it is likely to have a higher pitch than what we are used to.
