What does Einstein's General Theory of Relativity describe?

• The speed of quantum particles

• The curvature of space-time due to mass and energy

• The fixed positions of stars in a galaxy

• The chemical composition of black holes
  

What causes gravitational time dilation?

• The relative motion of objects

• The curvature of space-time in a strong gravitational field

• The presence of a magnetic field

• The expansion of the universe

According to general relativity, how does time behave in stronger gravitational fields?

• Time becomes irrelevant.

• Time moves faster.

• Time behaves unpredictably.

• Time moves slower.

Gravitational time dilation is most noticeable near which of the following?

• A black hole

• A neutron star

• A satellite in geostationary orbit

• A planet’s surface

What is a Rogue Planet?

• A planet orbiting two stars

• A planet with an unusually high number of moons

• A planet with no star or solar system, drifting in space

• A planet located outside the Milky Way galaxy

Why might rogue planets still retain an atmosphere?

• Due to the presence of strong magnetic fields

• Due to their proximity to a star

• Due to frequent collisions with asteroids
  

• Due to their own gravity and internal heat

What does the Big Bang Theory describe?

• The collision of two galaxies

• The origin and evolution of the universe from a singularity

• The creation of black holes

• The formation of planets in the Solar System

What is the Cosmic Microwave Background (CMB)?

• The sound waves created by stars in the universe

• The light emitted by the Sun and other stars

• The reflection of starlight from distant galaxies

• The remnant heat radiation from the Big Bang

How was the universe's accelerating expansion first observed?

• By analyzing black holes

• By detecting gravitational waves

• By studying distant supernovae

• By measuring the CMB's fluctuations

Which exoplanet is closest to Earth?

• Proxima Centauri b

• Kepler-452b

• 51 Pegasi b

• HD 209458 b
