what exactly is the universe

[OneIn1]

Also if sound is how humans communicate [standard to us] - what is the standard form of communication for ALL of this? .

Humans communicate mostly with body language, i think about 55%. which isnt hard to conceive if you think about how u cant have a conversation with another species, or humans who dont speak ur language for that matter, so through evoluton we relied on the body for our tool of communication.

There is also no air in outer space so sound cannot travel unlesss.....u assume it is still there but is not receivable or conceivable by our minds and devices.

I think information is the language of the universe.
