- No object or signal can move faster than the speed of light.
- According to the special theory of relativity, which was developed by Albert Einstein in 1905.
- Space and time are relative, and all motion must be relative to a frame of reference, according to Albert Einstein's theory of relativity.

Consider the following statements:(a) No object can move faster than t...
Explanation:
Statement (a): No object can move faster than the speed of light
- This statement is based on Einstein's theory of relativity, which states that the speed of light in a vacuum is the ultimate speed limit in the universe.
- According to this theory, as an object with mass approaches the speed of light, its mass increases, requiring more energy to accelerate it further. This results in an infinite amount of energy being needed to reach the speed of light, making it impossible for any object with mass to exceed this speed.
Statement (b): Space and time are relative and all motion must be relative to a frame of reference
- This statement is also derived from Einstein's theory of relativity, which revolutionized our understanding of space and time.
- In this theory, space and time are interwoven into a single continuum known as spacetime. The concept of a frame of reference is crucial in relativity, as motion is always measured relative to a specific frame.
- This means that an object's velocity, acceleration, and even its position in spacetime are all relative to the observer's frame of reference.
Conclusion:
Both statements (a) and (b) are correct, as they are fundamental principles of modern physics and have been validated through numerous experiments and observations. The theory of relativity has had a profound impact on our understanding of the universe and has stood the test of time in explaining a wide range of phenomena.
