hi semi,

you know its funny with what parts of a non-typical word grab one's attention. never even thought of gy (do you mean because of gynecologist ?). i always see gym, like the kind you work out in.

I always thought it was GIM as in Kim. OR GIMP. Bring out the GIMP!

I thought it was supposed to be "Gym Eejet", where "Eejet" was dialect for "Idiot". I couldn't tell if he was presenting himself as an idiot who liked to hang out in gymnasia, or someone who felt like an idiot while in a gymnasium.

actually, i was thinking of the speed, more than light itself. since i recall that light travels at that speed, only when in a vacuum.

i dont know if i am completely sold on the special relativity stuff, but if true, i think that speed is a pretty big clue for us. dont know if we will ever figure it out, though.

Not just speed. Acceleration. The idea of acceleration and movement, or speed is fundamental to it's "relative" position in space.

light and the special theory of relativity deal only with non-accellerated motion. i just think both theories have issues that are not easily resolved, so i cant say that i think that either one of them are correct. although i have no doubt that they have had and do have a lot of value to them.

Wow you have been reading. Nice. But I was referencing a way to look at the physical world and think of how particle are reacting. Here's one for you. When light is created it instanesly occupies all inertial reference frames. In that context in never accelerates. It just exists until destroyed. But gravity can slow the "time" it takes to reach us.

hi rc,

most of my physics knowledge comes from my 2 years of very intense and exhaustive physics learning in school.

i dont quite get your last statement. you say that when light is created, it is in all inertial frames. but gravity can slow it down to reach us.

since light only travels at c, it can take billions and billions of years to reach us, because of DISTANCE.

i am not understanding the point you are making to me.

gravity "slows" light by forcing it to travel through more space. Instead of reaching you from a distant star at an exact straigt line, it curves around gravitational objects. Thus affecting the "time" it takes to reach you. I only brought that up because of an earlier discussion on space time. And what lead me to it was your comment on acceleration and special relativity. Which lead me to the thought that time exists from creation to destruction in all intertial references. Try it with a flashlight. Sure you can't measure pico or nano seconds with your eyes. But in this experiment light exists at once and is thus destroyed when you flip the switch off at once. But not to the universe, it is "relative" to you. And any other observer. Having said all that, if light did not exist in every intertial reference frame then the idea that mass cannot exceed the spead of light ceases to exist. If we could accelerate, and this goes back as well, a particle that could reach a light emitter before the light left, we would travel back before the light was created and thus back before an intertial reference point and thus back in time.

hi rc,

before i try to answer your posts, i thought i would post a url, which explained inertial frames of reference. wanted to make sure that we were both talking the same language.

We are on the same page as long as the definition applies to Einstein, not Newton Mechanics. And also referencing special versus general theory of relativity. If you read the whole article it seems tp reference or back up my statement.

Quote:
Einstein's theory of special relativity likewise assumes the equivalence of all inertial reference frames, but makes a different additional assumption, namely, that the speed of light is the same when measured in all inertial reference frames. This second assumption leads to counter-intuitive effects that have been verified experimentally, including:

time dilation (moving clocks tick more slowly)
length contraction (moving objects are shortened in the direction of motion)
relativity of simultaneity (simultaneous events in one reference frame are not simultaneous in any frame moving relative to the first).

Thus affecting the "time" it takes to reach you. I only brought that up because of an earlier discussion on space time. And what lead me to it was your comment on acceleration and special relativity.

gymee - i have no problem with that. if you increase the distance that light travels, then you increase the time it takes to reach its destination.



rc - Which lead me to the thought that time exists from creation to destruction in all intertial references. Try it with a flashlight. Sure you can't measure pico or nano seconds with your eyes. But in this experiment light exists at once and is thus destroyed when you flip the switch off at once. But not to the universe, it is "relative" to you. And any other observer.

gymee - i dont know how this is significant. but i have no argument that someone light years away wont see my light switch off and on at the same moments that i do.




rc - Having said all that, if light did not exist in every intertial reference frame then the idea that mass cannot exceed the spead of light ceases to exist.

gymee - i am reading a conclusion, but i cant see the reasons for this conclusion.


rc - If we could accelerate, and this goes back as well, a particle that could reach a light emitter before the light left, we would travel back before the light was created and thus back before an intertial reference point and thus back in time.

gymee - not quite following you, here.
