from a human perspective, information is a central phenomenon of
this world. every one depends on it. nothing goes without
information. though, it is not possible to take hold of it. info
neither is material, nor is it energetic - but always refers to
it. that means information needs material or energetic carriers,
as for example electrons in a cable. sound waves are transmitted
through the molecules of the air. a satelite works with
electro-magnetical waves. a lot of animals recognise information
via ultrasound or even by using electro-magnetical fields.
