Supernovae 2
The spacetime diagram shows five stars which go supernovae at spacetime points
A, B, C, D, and E.
These supernovae are observed by astronomers on the Earth, and also by
scientists aboard a fast moving spaceship, the trajectories of which
are also shown on the spacetime diagram.
Answer the following questions:
-
In which chronological order do the five supernovae occur in the
Earth frame of reference?
-
In which chronological order do the five supernovae occur in the
spaceship frame of reference?
-
In which chronological order do the astronomers on Earth see
the supernovae?
-
In which chronological order do the scientists on the spaceship see
the supernovae?
-
Is the chronological order in which supernovae B and D occur
the same in all frames of reference? Explain.
