What is the difference between how digital information encoded into a hard drive and how information is coded into DNA? It just seems strange to me how you are able to encode information/data into a physical object.
When you load a game from a disc into an Xbox 360, example being Call of Duty, what is the information on the disc classified as? Is it just a different form of application software like Google Chrome or are you just loading a bunch of game files from the disc?
Is digital information that travels across the internet massless? If we were to take out the cables(and maybe the electrons)from the equation, is the digital information taking up physical space?
Because they are massless, could you theoretically fit an infinite number of Photons into a small space? There is probably an equation that proves this wrong but I'm curious.
Are there any other things/objects in our universe that are massless other than Gluons and Photons? I guess energy is massless, but it's not so much a thing, more-so a property.
Are photons(when described as a particle) considered objects? You can't see them on an individual level, but they hit you and interact with gravity. Might be a silly question, but was just debating it with a friend.
