The theory of special relativity explains the connection between space and time to objects that move in a straight line at a constant speed. The objects move at the speed of light. When an object approaches light speed, its mass is endless and cannot move faster than light. The most crucial postulate of Einstein's special relativity is that the laws of nature do not change in each frame of reference.

Which of the following best explains the reason for taking three measurements at each light intensity instead of a single measurement? Select one or more: a. By taking three measurements at each light intensity, the investigator could identify any result that was not expected and repeat the measurements until the expected result was obtained. b. By taking three measurements at each light intensity, the investigator could eliminate any result that did not support the hypothesis. c. By taking three measurements at each light intensity, the investigator could be more confident in the accuracy of the measurements than if the measurement had been made only once.

Austin did a measurement for the speed of light in an experiment. He found that the speed of light is 4.0 x 1018 m/s in air. When Nancy Drew saw his result, she immediately informed him that he made a mistake. How did Nancy know? O Light cannot have a speed. O His result would be correct if the experiment was done under water. O His result would be correct, if the light medium was in vacuum, but not in air. O None of the choices is correct. O Speed of light cannot be greater than 3 x 108 m/s.
