What then is Curved Space?
Curved space results when you take away some measure of space from a full flat space. In classical terms, our ordinary space is flexible, almost like rubber, and curved space is a fundamental property of our universe. Space is literally bent, it is curved by gravity. Gravity does not actually pull at objects as if strings are attached, instead it curves the space objects move within. Or to say it properly, gravity is the curvature of space-time. An example is our own planet Earth, which rotates around the Sun because the space around the Sun is curved. There are no invisible strings attached. The Earth would follow a straight path if space itself were not bent by the Sun’s gravitational field. The same is true even of a thrown baseball. Gravity from the Earth doesn’t actually pull at the baseball, instead space is bent so the baseball makes an arc as it flies through a curved space. At times, Albert Einstein considered the idea that the whole universe is curved into some kind of a clos
