laws of time disprove all witness testimony?

[Begrudge]

Every time you move or stop moving the rate at which you experience time changes. So, how can a witness say they saw something happen at a specific time, when the correlation of time is up to the observer? Like if you are on the sun and you got your watch on and have a magical telescope that lets you see super clear to earth and you watch a murder and note the time in a log and then return to earth the time at which you saw that would actually be a few minutes off the actual time so if you cannot really know when something happens how can witness testimony be a respectable defense in a non-bias defense system taking into account all reasonable assumptions?

The time disparity between the observer and the observed is negligible with respects to on-Earth encounters. Even if you were on the Sun, you would see events as they are happening on Earth, only 8 minutes behind. That is why if you ever actually sit on a Grand Jury or Jury, when times and dates are discussed, they use terms such as "On or around *insert time and day here*"

a reasonable assumption, like the witness was not 93 million miles away?

What if the universe already ended, and we just haven't seen it yet because it's so far away? :OOOOOO

Hey, its possible.

It's possible the sun disappeared right now. But we won't know for eight minutes if it has because even gravity is subject to the speed limit of C.

No, it isn't Gravity doesn't travel in any traditional sense. In addition, >c velocities are possible. The issue is switching between <c and >c velocities. Not to mention that c is the theoretical "speed limit" only in the sense of motion relative to, for lack of a simpler way of describing it in the context of a forum post, "self". Walking towards a wall while shining a flashlight on it will cause relative velocities >c, but not "objective" velocites >c. Gravity is a state of matter, and can travel faster than c without any problem. For example, if you were to shine a laser that was bright enough to be seen from the moon, across the moons apparent face, and you were to wave that laser from left to right, the actual speed at which the apparent spot of light _appears_ to travel across the moon would be faster than c, but there's no problem because nothing actually travelled at all, all that happened is that the point of luminescence changed locations at a >c rate. However, nothing's actually travelling in that scenario (other than the light from the laser to the moon and back to your eye, which happens at or near local c, depending on conditions). The "point of light" which you see, isn't an actual object or wave, and can move at any particular speed it wishes. If you calculate the distance between earth and any given star, and determine how far it "moves" from our viewpoint over the course of an hour, it will "move" much farther in that hour than light possibly could. However, that's just apparent motion, not actual motion. The star doesn't actual change positions faster than C, although it's apparent position from your viewpoint on earth travels much faster than c. Gravity isn't an object or wave, it's a property of spacetime, and its effects propogate instantly, although of course gravity itself isn't capable of impelling objects faster than c (unless they are objects that already travel above c, e.g. tachyons). Gravity's apparent field-of-effect propogates instantaneously.

In any case, time dilation is negligible between two points on planet earth which are within eyesight limitations, so that's irrelevant. However, eye-witness testimony isn't (and cannot be) exact due to a variety of other relative factors, but we've been aware of those since before science. Examples include: misconception, lack of light, confusion, personal agenda, etc. This is why witness testimony, in most courts throughout the world, is worth very little without corroboration.

I think the worst part is that people just have awful memories. People claim they can look at someone for maybe five seconds while he rushes out the door after committing a crime and ID him two months later in court? Yeah, right. Even if you had time to stare at his picture for 30 minutes you wouldn't be able to accurately reconstruct how he looks a mere five minutes after not seeing it anymore.

Also, particles that gain energy as they decrease in velocity? Wooooaaahhh!

Or burned to a crisp.

It seems to be the "I know enough vague details related to science and physics to make others blatantly aware that I have no idea what I'm talking about" thread.
