So now there is sound in space?
Despite what you’ve not heard, there are actual sounds in space. Though not as we first thought about it. I’m sure you have all seen the bell in a jar experiment.
Due to the virtual vacuum in space, it’s not sound like you and I experience it (that being waves pulsing through the air), but there are electromagnetic waves that pulsate at the same wavelength as the sound waves we can hear.
Thanks to instruments on several NASA probes including Voyager have recorded these waves and translated them into a sound that we can actually hear.
I guess this means we can only hear anything once we translate it to sound waves.
