So I don't see why zero is more special or "absolute" than any other number. And nothing that happens in the Andromeda Galaxy 2 million light years away can have any effect on me for 2 million years, and nothing I do can have any effect on Andromeda for 2 million years. So even asking "what are things like right now on Andromeda?" is a ambiguous question. Does it mean how things look in my telescope when light left Andromeda 2 million years ago? Or does it mean Andromeda 2 million years in the future when something I do here can make a change there? So what does "right now" even mean?
