Einstein's Theory of General Relativity and Black Holes

What was the main issue with Newton's theory of gravity that Einstein's theory resolved?

• It couldn't explain the orbit of Mars.

• It failed to predict the orbit of Mercury accurately.

• It didn't account for the existence of black holes.

• It was unable to describe the motion of comets.

How does Einstein's theory of general relativity describe gravity?

• As a result of the Earth's rotation.

• As a magnetic field around planets.

• As a curvature of SpaceTime caused by mass.

• As a force between two masses.

What happens to light in a curved SpaceTime according to Einstein's theory?

• It stops moving entirely.

• It travels in a straight line.

• It bends around massive objects.

• It speeds up significantly.

What did Carl Schwarzschild calculate in 1915 regarding black holes?

• The conditions under which a black hole forms.

• The speed of light in a vacuum.

• The distance between the Earth and the Sun.

• The curvature of SpaceTime around the Earth.

What significant discovery was made in 2015 related to black holes?

• The measurement of the speed of light near a black hole.

• The discovery of a new planet near a black hole.

• The detection of gravitational waves from colliding black holes.

• The first photograph of a black hole.
