How does the same event appear different when observed from different positions?
Depending on their positions relative to the events, taking it that one of the events are closer to each observer. Therefore, each observer will see the event closest to them first, making it appear that the events happened in a different order.
Can two events be simultaneous?
2 events at the same time are known as simultaneous events. Simultaneous events for a particular observer is when the 2 events are at the the same time axis for the observer. For a different observer having some relative motion to the 1st observer, the 2 events will not be simultaneous.
Is simultaneity possible?
There is no absolute fact as to whether two spatially separated events are simultaneous. There is only a fact of simultaneity or its failure relative to an inertial frame of reference. That a moving clock slows and moving rod shrinks is something most of us get used to with a little thought.
Are two events simultaneously simultaneous?
Two events are not necessarily simultaneous to all observers. The consideration of the measurement of elapsed time and simultaneity leads to an important relativistic effect. Time dilation is the phenomenon of time passing slower for an observer who is moving relative to another observer.
What does the Earth-bound observer see as time moves?
The Earth-bound observer sees time dilate (get longer) for a system moving relative to the Earth. Alternatively, according to the Earth-bound observer, time slows in the moving frame, since less time passes there.
Does elapsed time depend on who observes it?
Elapsed time for a foot race is the same for all observers, but at relativistic speeds, elapsed time depends on the relative motion of the observer and the event that is observed. (credit: Jason Edward Scott Bain, Flickr) Do time intervals depend on who observes them?
How is the passage of time different in different frames?
The passage of time is different for the observers because the distance the light travels in the astronaut’s frame is smaller than in the Earth-bound frame. Light travels at the same speed in each frame, and so it will take longer to travel the greater distance in the Earth-bound frame. Figure 3.
