Relative gravity entropy

How was Albert Einstein's Special Theory of Relativity initially received by the scientific community?

• It was immediately accepted as a groundbreaking theory.

• It was largely ignored or met with ridicule for being too radical.

• It was seen as a minor correction to Isaac Newton's theories.

• It was praised by politicians for its traditional approach.

What was a significant limitation of Einstein's Special Theory of Relativity that he sought to address?

• It only applied to objects moving slower than the speed of light.

• It did not account for the effects of magnetic fields.

• It only applied to observers moving at a constant speed in a straight line, not in accelerating frames or in the presence of gravity.

• It failed to explain the behavior of subatomic particles.

What was Einstein's key realization from his thought experiment about a falling window washer?

• Falling objects accelerate at different rates depending on their mass.

• In free fall, an observer would feel weightless, similar to being in space, implying an equivalence between gravity and acceleration.

• Air resistance is the primary force acting on falling objects.

• The speed of light is constant regardless of the observer's motion.

What was Einstein's profound insight regarding gravity and spacetime, which led to the General Theory of Relativity?

• Gravity is a force that pulls objects towards each other.

• Gravity is a result of the curvature of spacetime caused by mass and energy, making the shortest path between two points a curved line.

• Gravity is an illusion created by the observer's motion.

• Gravity only affects objects with significant mass.

How does Einstein's theory of gravity differ from Newton's?

• Newton believed gravity was a force acting within space-time, while Einstein saw it as a mysterious force acting at a distance.

• Einstein proposed gravity is a mysterious force acting at a distance, while Newton believed it emerged from the interaction of space and matter.

• Newton viewed gravity as a mysterious force acting at a distance, whereas Einstein's theory describes it as emerging from the interaction of space and matter.

• Both Newton and Einstein agreed that gravity is a force that affects the underlying space and time.

Which statement accurately summarizes the relationship between space-time and matter in Einstein's theory of general relativity?

• Matter tells space-time how to move, and space-time tells matter how to curve.

• Space-time tells matter how to move, and matter tells space-time how to curve.

• Space-time and matter are independent entities that do not influence each other.

• Matter and space-time both move and curve independently.

What phenomenon provided crucial early evidence supporting Einstein's theory of General Relativity?

• The consistent elliptical orbits of all planets around the Sun.

• The precession of Mercury's orbit, which could not be explained by Newton's equations.

• The observation that light always moves at the same speed regardless of the observer's motion.

• The discovery of black holes, which were predicted by Einstein's equations.

How does gravity affect time according to Einstein's theory?

• Time speeds up in stronger gravitational fields because light has a shorter distance to travel.

• Time slows down in stronger gravitational fields because light travels a longer path in curved space-time while maintaining a constant speed.

• Gravity has no effect on the passage of time; it only distorts space.

• Time passes at the same rate everywhere in the universe, regardless of gravitational influence.
