Physicists throw around the term time as if it were some thing changeable, let alone even a a thing itself.
Time is a constant measurement. A second is a second, and always will be. I don't get how in some situations time can "slow down."
No, what they mean is it takes less time to get somewhere basically, the faster you go. They just put it into the term you described above for the layman.
Like, I could walk to your house, or I could drive. Driving takes less time, even though it's the same distance. The earth, people, etc. move at the same pace, but you're moving faster. It all appears normal until you approach light speed, then it gets weird.
Now, remember I said everything around you moves at the same pace, except you, because you're moving faster? Well, if you go fast enough, near light speed, and everything around you moves at it's normal pace, it's almost like they're standing still. They move so much slower than you do, in relation to your speed, that time appears to slow down, or stop altogether.
If you could go the speed of light, for an hour, you could theoretically go into the future, due to what I explained above. You'll be moving ridiculously fast. Faster than the hand on a clock moves, faster than the blink of an eye.
The sattelites that gives us the internet that you're on, or that track gps signals do this. In order to accurately tell you where to go next, they have to track your signal, gather information, and send info back to tell you where to turn next. And they have to do this way before you even approach where you need to turn, so it seems instantaneous.
They are actually moving faster than you are on the ground, sending information faster, and processing it faster, at lightning speed. So on the ground, it feels instantaneous, but actually, what's happening already happened way before you receive the information.
There are more examples of this, and I'm no expert, but this has been scientifically proven, it's backed up by Einstein's equations, and it proves how time travel could be possible.(well, at least forward time travel. Backwards time travel is still unlikely)
It's not like time is linear by any means, or that time exists, but that the faster you move compared to your environment, the slower everything will move around you, only because you are moving a million times faster. It's like showing a fbf animation at 24 frames per second with only 5 frames of animation. The frames move so much faster than your eyes can read them, that the animation appears only a second long. If you lower the fps than it will appear longer.
That's the basic concept, tho I'm no quantum physicist, so I can't really elaborate much further, but that's basically how I understand it. Could be missing something, but yea.
