Gravity is the force that attracts two objects with mass towards each other. It's what keeps planets in orbit around the sun and holds us on the Earth's surface.

Radio waves are a type of electromagnetic radiation, which is a form of energy that travels through space. These waves have long wavelengths and are used for various communication purposes, including transmitting signals for radio, television, and even satellite communication. They are part of the electromagnetic spectrum, which also includes visible light, microwaves, and X-rays.
