Question

From the given information, find the speed of this fame with respect to the Sun-Earth rest frame.

If the Sun blows up at some instant and four minutes later we on Earth sit down
to eat lunch, those two events are separated by a spacelike interval. The Sun's
blowup cannot possibly have influenced us at the time we sat down, because it takes
8 minutes for light to reach us from the Sun. And since the interval is spacelike,
there must be a reference frame in which the two events are simultaneous. Find the
speed of this frame relative to the Sun-Earth rest frame.
