ELI5 the anti MP3 push from 2002

Okay so I was watching The I.T. Crowd and there was a sticker that on the door that says “MP3 is not a crime” and I looked it up and I couldn’t really understand anything I was reading (maybe it’s been a long day).

The articles reference something called Napster, legal battles, consumer rights in music media, MP3s (remember those?), MUSIC (the organization, ig?), and I couldn’t understand much of the words or the situation.

Anyways, would love a simplified explanation because it does seem fairly interesting and, from what I did pick up, something relevant as video game companies stop making physical copies of games so that no one really “owns” what they buy.

ELI5: Einstein’s theory of relativity, how does the biological time change??

Title basically, i just watched interstellar for the first time yesterday, and while i can understand the theory itself, i don’t understand how the biological time changes. For example, lets say i’m someone in space where 1 hour there is 10 years on earth, my organs would age 1 hour yet on earth for someone they will age 10 years? Like are organs, cells, our body bounded to a “general/universal” time where they age almost at the same rate for all humans but somehow differ when in different places of space or what?

Sorry if i’m not making it clear but this has been something i always thought about ever since i heard of the theory lol
