Today in science class we were talking about waves, you know, sound waves and radiation and other types of waves. So, the science teacher was saying that sound is basically just a mechanical latitudinal wave. So then, I asked him if sound travels in a vacuum. He said no, because there is nothing in a vacuum. No air or nothing. I asked him why, and he said that he didn't know. I understand that space doesn't have any air in it, but how can there be nothing at all? There must be something in the vacuum like air, right? Can you tell me, I was mind blown today. I always thought that in space there was a different form of air, or something that sound could go through, but nothing is crazy!!! Please Explain, I hope you can...
