curved space and relatavistic effects
« on: April 17, 2006, 07:29:00 AM »
since space and time can be warped, all in the universe is not as it seems. time and distance are dilated and what we percieve to be curvature may only be since light is refracted by warped space therefore gives the idea of curvature.
reality is what we percieve. is the earth flat? maybe yes, maybe no. it is all in the eye of the beholder.
does light travel in a straight line? not near large gravitational fields, or when pasing from one medium to another, thus our brains are fooled by illusions..
is the speed of light only constant in a vacuum or does it change when entering a denser medium? maybe yes, maybe no.
there are many unanswered questions out there. great to see at least some people putting up an argument. :lol:

light does change speed in a medium, its not a maybe, it does.

Refraction is a demonstration of this.

This "maybe it is, maybe it isn't" talk is all so much hot air.  When we say "The Earth is flat" or "the Earth is spherical", it's pretty clear that these terms are using the local metric of spacetime to describe what we mean by "flat" and "spherical".

There's no ambiguity.  I encourage others not to take this thread seriously.

we assume light changes speed on refraction only because we will not accept that frequency, thus time itself changes. the speed of light appears to change, but does it really?????? or does frequency change?

Well, considering the speed is directly proportional to the frequency, they both very obviously change.

thats correct unimportant, but in classical physics only wavelength and speed actualy change whilst frequency remains constant. as einstein said, the speed of light is constant in a vacuum.
what about a different medium? do we measure this speed relative to ourselves, or if we could get inside the medium, would we still measure the speed as the same or different. this poses many more questions than answer.
such as. is the distance between earth and moon a long distance awya or a long time? is the curvature of space around the masses enough to make a rocket move through a very long curved path, which we percieve as a straight line?
its not impossible and we should all keep an open mind.

I agree with Erasmus. What the hell are you talking about?

Ask your questions there and I wish you the best of luck to understanding the explanations.

Physicists know the answer to your dilehma about light traveling below "c" in certain mediums. I have pondered about this question myself, found the explanation, but was unable to understand it.

There are many unanswered questions, but there are also many answered questions that you think are unanswered. If you really want to learn something I suggest going to the physics forums rather than the flat earth forums, no offence.
