Which of the following is not a prediction made by the theory of relativity?

[bobprobe2001]

a. No material object sent outward from Earth can reach or exceed the speed of light.

b. Observers in different reference frames will always see their own lengths and masses as "normal", and see their own clocks running normally.
Observers in different reference frames may disagree about the time and distance between two events.

c. Observers in different reference frames may disagree about the basic laws of nature.

d. E = mc2

The answer is c., because one of the postulates (or assumptions) of special relativity is that the laws of physics are the same in all inertial frames of reference. Two observers will separately find that the laws of physics (i.e. conservation of energy, conservation of momentum) hold true; they may disagree on things such as the simultaneity of events but each observer will still be "correct" from the viewpoint of his or her own frame of reference. It is because there is no preferred frame of reference (the basic laws of nature are the same) that two observers can disagree on simultaneity.
