CORE DEFINITION

When a celestial body (such as a satellite) orbits another larger celestial body (such as a planet), if it gets too close, its own gravity cannot resist the tidal forces of the larger body, and it will be torn apart (forming a ring). This critical distance is the Roche limit.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

The death distance of attachment. When attaching to a strong entity (such as a major client or platform), maintaining distance is key to survival. If you get too close, your internal structure (independence) will be torn apart by the other's immense gravity (tidal forces), turning you into their ring (vassal).

Anchor fast decisions

When a satellite orbits a planet, if its orbital radius is less than the Roche limit, the tidal gravitational force exerted by the planet on the near side of the satellite exceeds the satellite's own gravity, causing the satellite to be torn apart, and the debris often forms a planetary ring.

Gravity Assist

A gravity assist, gravity assist maneuver, swing-by, or generally a gravitational slingshot in orbital mechanics, is a type of spaceflight flyby which makes use of the relative movement (e.g. orbit around the Sun) and gravity of a planet or other astronomical object to alter the path and speed of a …

Orbital Velocity

The orbital velocity of a celestial body, generally a planet, natural satellite, artificial satellite, or a star in a multiple star system, is the speed at which it orbits the barycenter of the system, usually a more massive body. It can be used to represent the average orbital speed as the body completes one revolution, or its instantaneous orbital speed, i.e., its speed at a specific point in its orbit. The speed of a body at any point in its orbit can be calculated from its distance to the central body; the orbital energy of the body is independent of its position, and is equal to the sum of kinetic energy and potential energy. Thus, under ideal conditions, the orbital speed v {\displaystyle v\,} is: In general: …

Gravitational Lensing

Gravitational lensing, according to general relativity, occurs when light from a background source passes near a gravitational field (such as a galaxy, galaxy cluster, or black hole), causing the light to bend as if through a lens. The degree of bending depends mainly on the strength of the gravitational field. Analyzing the distortion of the background source can help study the properties of the intervening gravitational field acting as a 'lens'. Depending on the scale and effect, gravitational lensing can be divided into strong and weak lensing. Orest Khvolson (1924) and Frantisek Link (1936) are considered the first to discuss this effect in papers, but it is usually associated with Einstein, who calculated it in 1912 and published an article on the subject in 1936. In 1937...
