Orb

Orb

An orb is a spherical object or shape. The term is often used in various contexts, including astronomy, geometry, mythology, and photography. Orbs can be natural or man-made and can vary significantly in size and composition.

Astronomy

In astronomy, an orb typically refers to a celestial body such as a planet, moon, or star. These objects are generally spherical due to the force of gravity pulling matter into a shape that minimizes potential energy. The Earth, for example, is an orb.

Geometry

In geometry, an orb is a three-dimensional shape known as a sphere. A sphere is defined as the set of all points in space that are equidistant from a given point called the center. The distance from the center to any point on the sphere is called the radius.

Mythology and Symbolism

In various mythologies and religions, orbs often symbolize power, authority, and divinity. For instance, the orb and sceptre are traditional symbols of monarchical power in many cultures. The Holy Hand Grenade of Antioch from the legend of King Arthur is another example of an orb in mythology.

Photography

In photography, particularly in the context of paranormal investigations, orbs are often considered to be visual artifacts. These are usually caused by the reflection of light off dust particles, water droplets, or insects, and are often mistaken for supernatural phenomena.
