The Attempt at a Solution

i would assume you have to use a solid to communicate but I'm not sure how it would work

You touch your helmets together and speak loudly. You want to have as much surface area contacting as possible, so if the helmets are nearly spherical it might not work.

I would first like to clarify that sound waves do require a medium to travel through, but this medium can be any substance - solid, liquid, or gas. In this case, the medium would be the space suits that you and your friend are wearing.

To communicate verbally, you can use bone conduction. This is a method where sound waves are transmitted through the bones in your body, bypassing the need for air as a medium. Since you and your friend are in close proximity, you can tap on the space suits or helmets to create vibrations that will be transmitted through your bones and be interpreted as sound by your inner ear. You can also try speaking directly into your friend's helmet, as the vibrations from your voice will travel through the space suit and be heard by your friend.

Another option would be to use sign language, as your movements and gestures can be seen through the transparent visors of your space suits. This would require some prior knowledge of sign language, but it would be an effective way to communicate without the need for sound waves.

Overall, it is important to remember that sound waves can travel through any medium, including solids like your space suits. By utilizing bone conduction or sign language, you can effectively communicate with your best friend despite the broken communicators.
