In some inertial reference frame, two events happen one second apart at a distance of 1 astronomical unit apart. Identify all of the following three statements that are true about the two events: 1) There exists an inertial reference frame in which the two events occur at the same time 2) There exists an inertial reference frame in which the two events occur at the same position 3) There exists an inertial reference frame in which a beam of light emitted at the first event reaches the second event.
