What is the geocentric model of the universe?

The model in which the Sun is at the center and all planets orbit it The model in which Earth is at the center of the universe and all other celestial bodies orbit it The model in which every galaxy has its own center The model in which the Moon is at the center of the solar system

What did Nicolaus Copernicus propose in 1543?

That the Moon causes Earth's seasons The heliocentric model — that the Sun, not Earth, is at the center of the solar system That planets orbit in perfect circles at constant speed That gravity decreases with distance

What did Galileo discover when he turned his telescope toward Jupiter in 1609?

That Jupiter has a Great Red Spot That Jupiter has rings like Saturn Four moons orbiting Jupiter, proving not everything in the sky orbits Earth That Jupiter is made of gas

What did Isaac Newton publish in 1687 that explained why planets stay in orbit?

His theory of special relativity, showing that space and time are linked His law of universal gravitation, showing that every mass attracts every other mass His three laws of planetary motion based on telescope data His discovery that light is made of particles called photons
