Who among the following scientists was associated with the theory of Relativity?

The correct answer is Einstein.

Key Points

• Albert Einstein is best known for his Theory of Relativity, which revolutionized the understanding of space, time, and gravity.
• The Theory of Relativity includes two key components: the Special Relativity (1905) and General Relativity (1915).
• Special Relativity introduced the famous equation E=mc², establishing the relationship between energy (E), mass (m), and the speed of light (c).
• General Relativity extended these ideas to include gravity, describing it as the warping of space-time by massive objects.
• Einstein’s work laid the foundation for modern physics, influencing fields such as cosmology, quantum mechanics, and astrophysics.

Additional Information

• Special Relativity: This theory focuses on the relationship between space and time for objects moving at constant speeds in the absence of gravity. A key concept is that the speed of light is constant for all observers.
• General Relativity: This theory explains gravity as the curvature of space-time caused by mass and energy. It predicts phenomena such as black holes and gravitational waves.
• Gravitational Waves: Predicted by Einstein in 1916, these are ripples in space-time caused by accelerating massive objects. They were first detected in 2015 by the LIGO observatory.
• Time Dilation: A phenomenon from relativity where time appears to move slower for an object moving at high speeds or in a strong gravitational field relative to an observer.
• Legacy: Einstein received the Nobel Prize in Physics in 1921, not for relativity, but for his explanation of the photoelectric effect, which was crucial for quantum theory development.
