Doctor Who is a beloved science fiction character who travels through time and space in his TARDIS, a time-traveling machine disguised as a blue police box.

A temporal paradox refers to the seemingly contradictory situation where two versions of the same individual coexist within the same timeline, often leading to complex and paradoxical scenarios.

String Theory suggests that time, along with other dimensions, is part of a multidimensional fabric known as spacetime, challenging the traditional notion of a linear timeline.

The event horizon is the boundary surrounding a black hole beyond which the gravitational pull becomes so strong that nothing, not even light, can escape.

A time machine is a fictional device that enables individuals to travel forward or backward in time, often depicted in science fiction stories and films.

Albert Einstein formulated the theory of relativity, which challenged classical notions of time and space and introduced the concept of spacetime.

The bootstrap paradox refers to the scenario where an individual travels back in time and provides the means for their own existence, creating a self-referential loop.

The butterfly effect refers to the idea that small changes in the past can have significant and unpredictable consequences in the future, often depicted in time travel stories.

H.G. Wells is considered a pioneer in the genre of science fiction, with his works such as "The Time Machine" and "The War of the Worlds" exploring concepts of time travel and the temporal continuum.

Temporal dilation refers to the phenomenon where time passes at different rates for observers in different frames of reference, as predicted by the theory of relativity.

In the film "12 Monkeys," the protagonist is sent back in time to prevent a deadly virus from being released, but his actions inadvertently lead to the outbreak.

The grandfather paradox refers to the scenario where an individual travels back in time and prevents their own birth, creating a logical contradiction.

Temporal branching refers to the idea that time can split into multiple timelines, each with its own unique set of events, as a result of actions taken in the past.

In the film "Interstellar," the astronauts travel through a wormhole and experience time dilation, with one hour on the distant planet equivalent to seven years on Earth.
