Einstein's Legacy: The Ultimate General Relativity Challenge Quiz

General Relativity predicts that the bending of light is caused by the gravitational attraction of massive objects. This phenomenon is often referred to as gravitational lensing.

Time dilation in General Relativity occurs due to the warping of spacetime in the presence of mass. Clocks in strong gravitational fields run slower compared to clocks in weaker fields.

The "Einstein Cross" is an example of gravitational lensing, where a massive object (like a galaxy or black hole) bends and distorts the light from a background object, creating multiple images.

Einstein's General Theory of Relativity describes the behavior of matter and the effects of strong gravitational fields. It is a theory of gravitation that supersedes Newtonian gravity by accounting for the curvature of spacetime caused by massive objects.

The LIGO and Virgo collaborations detected gravitational waves in 2015, providing direct evidence of their existence and confirming a key prediction of General Relativity.

The Einstein field equation describes how mass and energy determine the curvature of spacetime. It's a foundational concept in General Relativity, linking the presence of matter and the curvature of spacetime.

The observed orbit of Mercury showed discrepancies that were explained by the effects of General Relativity. These discrepancies were not accounted for by Newtonian gravity.

In the context of General Relativity, acceleration due to gravity is equivalent to the force of gravity itself. This equivalence is a fundamental concept in the theory.

The Equivalence Principle in General Relativity states that the inertial mass (resistance to acceleration) of an object is equal to its gravitational mass (the force it experiences due to gravity). This principle is a foundational concept in General Relativity.

Arthur Eddington's observations during a solar eclipse in 1919 provided some of the earliest experimental evidence confirming Einstein's General Theory of Relativity, specifically the prediction of light bending by gravity.

General Relativity predicts the existence of event horizons around black holes. The event horizon is the boundary beyond which nothing, not even light, can escape the gravitational pull of the black hole.

Albert Einstein presented his General Theory of Relativity in 1915, fundamentally changing our understanding of gravity and the universe.

General Relativity predicted the existence of gravitational waves, which are ripples in spacetime caused by the acceleration of massive objects. The LIGO and Virgo collaborations confirmed the existence of these waves in 2015.

General Relativity explains the motion of planets and other celestial bodies in gravitational fields. It describes how the presence of mass warps the spacetime around it, influencing the motion of nearby objects.

The key differences between General Relativity and Special Relativity are:

Special Relativity: Formulated by Albert Einstein in 1905, Special Relativity deals with the physics of objects moving at constant speeds in straight lines (inertial frames of reference). It does not include the effects of gravity. It introduces the concepts of time dilation and length contraction for objects moving at speeds close to the speed of light.

General Relativity: Formulated by Einstein in 1915, General Relativity extends Special Relativity to include acceleration and gravity. It describes gravity not as a force but as a curvature of spacetime caused by mass and energy. This theory applies to all frames of reference, whether inertial or accelerating.

The correct key difference not listed in the options is:

Special Relativity deals with inertial frames of reference, while General Relativity includes both inertial and non-inertial (accelerating) frames of reference and incorporates the effect of gravity as a curvature of spacetime.
