  • Black holes are formed when massive stars die. The intense gravitational force that they exert allows nothing to escape.

    Black holes are one of the most active research topics in all of astronomy. Scientists around the world are exploring the link between black holes and their parent galaxies, looking for the "missing links" between supermassive and stellar-mass black holes, examining the environment around the black hole at the center of the Milky Way, and " listening "for the signature of black holes merging into gravitational waves.

    Isaac Newton: an apple a day keeps the moon in orbit
    Sir Isaac Newton publishes his universal law of gravitation in a three-volume work known as the Principia. Their calculations explain the orbital motions of the Moon, planets, and comets, and allow scientists to calculate the masses of astronomical objects. A century later, two scientists apply Newton's laws of gravity to calculate that a star of sufficient size and density could prevent light from leaving its surface, creating a "dark star."
    Albert Einstein extends his theory of relativity to include the effects of gravity. His equations show that gravity is a "warp" in space-time caused by matter. The more massive an object is, the more it warps the space around it. Known as general relativity, it provides the theoretical basis for black holes.
