Question

Based on what you know about Einstein and relativity, select all of the correct statements from the following list.

1. Curved space near massive objects causes other objects to orbit them.
2. General relativity is an extension of Newton's laws of motion.
3. Uniform motion through space is detectable without outside objects if approaching the speed of light.
4. Mass and energy are related.
5. Neither theory of relativity (general or special) has been experimentally tested.
6. The presence of mass curves space.
7. The speed of light you observe depends on your frame of reference.

Answer 1

Curved space near massive objects causes other objects to orbit them. True.

General relativity is an extension of Newton's laws of motion. General relativity can't be derived from Newton's law but Newton's law can be derived from general theory of relativity.

Uniform motion through space is detectable without outside objects if approaching the speed of light. False.

Mass and energy are related True.

Neither theory of relativity (general or special) has been experimentally tested. False

The speed of light you observe depends on your frame of reference. False.
