Suppose a spaceship is moving at a constant speed of 0.8c.
Then the ship sends a pulse of light to the same direction as of the ship.
Questions:
a) Will the speed of this pulse of light be c or c-0.8=0.2c ?
b) How is it to interpret from the ship's frame of reference?
c) How is it to interpret from the frame of reference of a stationary viewer
who is in a distance at a right angle parallel to the ships route when
the light knob was pushed?
Re: The real twin paradox. ... You have multiple reference frames in the problem as originally stated. ... There would be no paradox from that frame of reference. ... This is because each CHANGE in velocity is also a change of iFoR.... We can look at things from the viewpoint of a ship as long as it is ... (sci.physics.relativity)
Re: Expanding the gedanken ... different frame of reference the events would not be simultaneous. ... the ship occupy two spaces at the moment physically. ... Maybe you've not exaplined the scenario well enough ... (sci.physics.relativity)
