Spacetime Spacetime Lorentz factor formula, Non-Euclidean geometry, general relativity,Gravitational lensing 1 / 10 Which type of geometry is used to describe spacetime in general relativity? Non-Euclidean geometry Euclidean geometry Cartesian geometry Topological geometry 2 / 10 What is the shape of spacetime in the presence of a black hole? Flat Curved infinitely inward Spiral Cylindrical 3 / 10 What is the curvature of spacetime caused by? Speed of light Electromagnetic force Gravity Thermal energy 4 / 10 What does time dilation predict about a moving clock compared to a stationary one? It runs faster. It runs slower. It stops. It moves backward. 5 / 10 Which scientist formulated the concept of spacetime in the theory of relativity? Isaac Newton Albert Einstein Galileo Galilei Niels Bohr 6 / 10 What happens to spacetime as you approach the speed of light? Time speeds up and distances shrink. Time slows down and distances contract. Time remains constant and distances expand. Both time and distances remain constant. 7 / 10 Which phenomenon is explained by the warping of spacetime near a massive object? Doppler effect Gravitational lensing Wave-particle duality Photoelectric effect 8 / 10 A light beam takes 500 seconds to travel from the Sun to Earth. What is the distance between them? 5 × 10⁸ km 3.0 × 10⁸ km 7.5 × 10⁸ km 1.0 × 10⁸ km 9 / 10 What is the Schwarzschild radius directly proportional to? Object’s volume Object’s velocity Object’s energy Object’s mass 10 / 10 If a spaceship travels at 0.8c (80% of the speed of light), what factor will time slow down for passengers on the ship compared to those on Earth? 25 0.6 0.8 0.36 Your score is By WordPress Quiz plugin
