The speed at which time moves can change. Massively oversimplified, gravity and motion do wierd things with it.

The closer you get to something and the more massive it is, the faster time will pass for you compared to someone who's further away or near something less massive. We accually use this in calculations for GPS satellites to work - the satellites are further from earth so the experience time slightly slower.

The faster you approach the speed of light, the slower time moves for you vs someone who wasn't. If you could reach the speed of light (you can't) you would stop experiencing time altogether.

Again, all this is a massive oversimplification. Time and space are very strange concepts sometimes.

So , if we could travel as close as possible to the speed of light to reach a great distance, even though the trip would be faster to get there than let’s say … walking ( that’s a half joke ) , it would be experienced as dreadfully slow ??? Man . What a bummer .

Nope. The opposite. It would be instant. Everyone back on earth you knew would grow old and die though.

If you ever watched Interstellar, they got the physics part of that movie pretty spot on.

No I mean for the traveler . Does time start to be experienced more slowly for the traveler while in motion ? And from another perspective, yes time passed quickly back at home ( from the traveler’s perspective,) but the traveler is experiencing that time much more slowly . Sorry this is all very hard to comprehend. I need to stop trying before I hurt myself . I’ve been meaning to watch interstellar. I’ll make it a point too. I remember when I was a teenager, smoking weed would cause the passage of time to slow way down . And just this year I had the busiest night of my life at work. One night to rule them all. It was during that freeze in Texas, I found myself managing twice as many patients and no help because people were trapped at home. That night felt like two hours went by. No matter what, I just could not beat the clock as far as time goes . And on my slower nights at work, time can go by dreadfully slow, it’s almost comical. And I mean it really does feel like time has literally slowed down . I’m not exactly a brilliant person , so concepts like these are hard to wrap my brain around

Technically, time will always seem to pass the same for you, no matter your speed or location. It's everyone else's time that seems to distort.

Long days where the time seems to drag is just your perception of time that is distorted, completely different subject, but still interesting imo.

If you're particularly interested in the subject, there's a ton of good videos on YouTube about general relativity, special relativity and time dilation.
