physics

• Event horizon

  The event horizon is the theoretical boundary around a black hole beyond which no light or information can escape, making any event occurring there forever unobservable from the outside.

• Escape velocity

  Escape velocity is the minimum speed an object needs to achieve to break free from the gravitational pull of a planet or other celestial body without further propulsion.

• Gravitational pull

  The fundamental force of attraction that exists between all objects possessing mass in the universe, often used metaphorically to describe a strong, irresistible influence or attraction.

• Zero gravity

  The state in which the effects of gravity are not felt, typically experienced by objects or individuals in freefall or orbiting a celestial body.

• Critical mass

  The minimum amount of something required to start or sustain a particular process or effect.

• Static in the air

  An atmosphere that feels tense, uneasy, or emotionally charged, often signaling an impending conflict or significant event.

• Ripple effect

  A ripple effect describes a situation where an initial action or event produces a spreading series of indirect consequences or results.

• Butterfly effect

  The concept that a very small, localized change in a complex system can have large, unpredictable consequences elsewhere.
