Cosmos
The white section is the known part. I label the white part K for Known. The dark part is the unknown part. No information is reaching the known part from the unkown part. I label the black part U for Unknown. According to this picture Cosmos would be: Cosmos = K + U. I drew this picture to find out if Cosmic Background Radiation is cosmic. According to this reasoning Cosmic Background Radiation is NOT cosmic. What do you think? Is this a paradox? Is there something wrong with the reasoning?
