According to Einstein's theory of relativity,

which of the following statements best describes the relationship between space and time?

• Space and time are independent entities.

• Space and time are absolute and unchanging.

• Space and time are relative and interconnected.

• Space and time are perpendicular dimensions.

How does Einstein's theory of relativity challenge Newtonian physics?

• It proposes that gravity is a force that acts instantaneously.

• It suggests that time is constant and unaffected by motion.

• It predicts that objects in motion experience time dilation and length contraction.

• It confirms that the speed of light varies depending on the observer's frame of reference.

What is the fundamental concept behind Einstein's theory of general relativity?

• The equivalence of inertial and gravitational mass.

• The existence of a stationary, unchanging universe.

• The concept of absolute space and time.

• The principle of conservation of energy.

In what year did Einstein publish his theory of general relativity?

• 1905

• 1915

• 1920

• 1930

What is the fundamental concept that underlies Einstein's theory of special relativity?

• The principle of conservation of energy and momentum.

• The constancy of the speed of light in a vacuum.

• The existence of hidden variables governing particle behavior.

• The idea that space and time are separate and absolute dimensions.
