text: Theoretically, YES, but practically NO. sound propagation can only hapen through particles.. atoms or molecules to pass on the vibrations/energy by hitting each other. Space is not entirely empty, so in theory sound could travel, but in reality the transmission would be unnbelievably poor. Space has a sensity of arounf 1 atom per cubic cm!\n\n\n"Space, the final frontier. These are the words that might come to mind when you gaze up at the stars on a clear night. But wait a second, what is that dark stuff that separates all the stars? If you said it is space then you are partially correct. Outer space is divided into many levels and the one that separates the stars is called interstellar space.\n\nIt is often a misconception that space is a vacuum or simply empty. Space is a nearly perfect vacuum, even better than the best ones made in labs on earth, but it is not devoid of everything. The fact is that space is filled with tiny particles called cosmic dust and elements like hydrogen and helium. This applies for interstellar space also and all the previously mention particles make up what is known as the interstellar medium.\n\nThe interstellar medium is mainly made of lone hydrogen atoms. They do not even exist as pairs as they do "
