Final answer:
According to the theory of special relativity, c. no inertial frame exists where event 2 necessarily occurs before event 1 by acceleration or deceleration; it depends on whether the events are causally connected and their separation in spacetime.
Step-by-step explanation:
To answer the question of how to find an inertial frame in which event 2 occurs before event 1, it's necessary to understand the theory of special relativity. In the theory of special relativity, the sequence of events can be different in different inertial frames of reference, depending on their relative motion. However, if event 1 and event 2 are causally connected and event 1 causes event 2, then all inertial observers will agree on the order of these events. If the events are not causally connected, their order may differ in different frames of reference, provided that the separation between events is spacelike, meaning that they cannot influence each other due to the limit imposed by the speed of light.
Regarding the specific answers provided:
- Accelerating towards or away from events does not create an inertial frame since an inertial frame by definition must not undergo any acceleration.
- An inertial frame where event 2 occurs before event 1 can only exist if the events are spacelike separated and thus there's no definite order that all observers would agree upon.
The correct answer to the question is:
c) No inertial frame exists for this condition
One cannot find an inertial frame of reference where event 2 occurs before event 1 by simply accelerating or decelerating. It inherently depends on the nature of the events themselves (causally connected or not) and their separation in spacetime according to the theory of special relativity.
