quote:Originally posted by thebrain13Does light always have to move at c from you, even if its not traveling directly towards, or away from you? For example, if you drew a line from you, to a photon one light year away, and the photon was traveling perpendicular to the line. Would the photon be seen as traveling c from you, or at c from its starting point?
quote:Originally posted by thebrain13Many of einsteins thought experiments, featured light that never hits you.
quote:Just because something happens, not involving you doesn't mean it doesn't happen. There is plenty of light not traveling directly towards me, we are assuming I can view it with accuracy, just like Einstein does, just like many theorists do, about almost any theory. The question has arisen, this does happen. Either you know the answer or you dont. If you can answer it than do it.
quote:More precisely you could say if light isn't moving directly toward or away from you, it is always seen as moving under c.
quote:Originally posted by thebrain13 QuoteI am not talking about light traveling in the same direction as you. I know that light will always pass you at c. However light isn't going to be passing by anything in my example, its traveling perpendicular to you.once again for you to see light in a vacuum, for it to be viewed and measured its has got to be traveling towards you and therefore passing you.

quote:Originally posted by thebrain13Since you no longer view light to be constant if it is not moving directly toward or away from you, how is non c moving light, affected by your relative motion? How fast would you view light in this case. Lets say you were traveling at .99c relative to a starting point, a flash of light starts from the same starting point perpendicular to your motion at the same time, how fast do you see the light traveling relative to you, and how fast do you see it traveling relative to the starting point? Now what if you were traveling at .1c?
quote:Originally posted by thebrain13ukmikey redshifting wont change its velocity. So how does bouncing off something change the experiment?
quote:The velocity of an object is simply its speed in a particular direction. Since velocity is defined as a vector, both speed and direction are required to define it.

Where m is measured distance dimension.S is time-unit.When time unit is 1s it is 1s it cannot be anything else.But this is the whole essence of relativity – what may appear as 1 second to you, may appear as 10 seconds to someone else, or 0.1 second to another person (all assuming they are in different inertial reference frames). Likewise, what may appear as 1 metre to you, may be 10 meters to someone else, and 0.1 meters to another.George
quote:Originally posted by heikkiHi, A_s.I havent read that mentioned theory of relativity and your wrotes is kind strange for me. When time-meauring unit is 1s it is 1s at all points, everywhere.But, now i must says goodbay at this forum. It seems that you and other else who speak this forum, have read some theoryes and scient-books and then my thoughts are not same-kind than these books are, so then happend un-necessary different understanding.I hope you nice life forward.
