I was just googling on how does radio waves travel in space and stumbled upon this reddit post If sound can't travel through space, how can radio waves? and the idea that sound can't travel in space caught my attention.
Although it makes absolute sense that sound needs medium to travel from one end to another, has this actually been tested in space somehow? if "theoratically" I was able to shout in a void space would I look like this dog?
I still have my doubts.
