Of course whether fictional characters act within the laws of physics is a moot point, but that’s not really what I’m saying. I could be wrong, but I’m pretty sure that most people view interstellar travel, as portrayed in sci-fi media, as something that one day could happen. There’s even a...

True, but I think that a lot of people believe that there may be ways to "cheat" this, like finding some way to get form A to B without actually traversing space (wormhole or something), and most scifi goes in this direction (oh we are folding space). I guess what I'm saying is that the issue...

Thanks for the reply! What you're saying makes total sense, and I think I've been kind of clumsy trying to explain my confusion/question here. Where all of this came from was FTL travel in scifi media, so let me try to use a hypothetical from that to better explain my concern. Assume that Han...

Interesting! Also, I'm just curious, because this is what's really throwing me for a loop. If you were able to travel to a distant planet nearly instantly using some kind unknown method, "when" relative to the world you traveled to, would you arrive there? Because I feel like in order to...

Thanks for your detailed response! I know that my language is clumsy here, but I think I did get the answer I was looking for, which is basically that FTL travel, like we see in sci-fi media where people travel halfway across the galaxy and then back with no apparent time dilation, just as if...

Hmmm but if we’re talking about coordinate time, we’re only talking about an abstract mathematical concept correct? So statements like “Bob and Mary both experienced biting into their food at the same time” don’t really make any sense, because here, we’re talking about two separate people...

Thanks Dale! This terminology is actually really helpful for me to try to explain what I’m trying to ask better. So if you wouldn’t mind indulging me further, I would like to express my question a bit better with two scenarios… scenario 1: Bob and Mary both live in the same neighborhood...

Hi Everyone, Just a disclaimer, I'm not a physicist or a physics student, just a layperson with an interest in physics. So please forgive any lack of understanding on my part :). Anyway, I recently started trying to gain a better understand of what time is in the real world, because some...

Hey Everyone! So disclaimer, I'm not involved with physics professionally or educationally, it's just a hobby I like to think about, so please excuse my ignorance :). Anyway, I had a thought, and I was wondering if you guys could elucidate it. Imagine that we have a hypothetical telescope...
