A spacetime diagram is a graphical illustration of locations in space at various times, especially in the special theory of relativity.Spacetime diagrams can show the geometry underlying phenomena like time dilation and length contraction without mathematical equations.
In physics, spacetime, also called the space-time continuum, is a mathematical model that fuses the three dimensions of space and the one dimension of time into a single four-dimensional continuum. Spacetime diagrams are useful in visualizing and understanding relativistic effects, such as how different observers perceive where and when events ...
The Mr. Fusion Home Energy Reactor is the name of a power source used by the DeLorean time machine in the Back to the Future trilogy. It can be seen for the first time at the end of Back to the Future when Doc pulls into the McFly's driveway after a trip to the year 2015. It was a piece of technology he was only able to obtain due to his ...
Any movie that involves the space-time continuum and the laws of physics is bound to be a trip and a half—and Netflix's slasher ... Lucy is able to wrangle the Sweetly Slasher back to the future ...
A temporal paradox, time paradox, or time travel paradox, is a paradox, an apparent contradiction, or logical contradiction associated with the idea of time travel or other foreknowledge of the future. While the notion of time travel to the future complies with the current understanding of physics via relativistic time dilation, temporal ...
If using a system of units where the speed of light in vacuum is defined as exactly 1, for example if space is measured in light-seconds and time is measured in seconds, then, provided the time axis is drawn orthogonally to the spatial axes, as the cone bisects the time and space axes, it will show a slope of 45°, because light travels a ...
The film was followed by two sequels, Back to the Future Part II (1989) and Back to the Future Part III (1990). Spurred by the film's dedicated fan following and effect on popular culture, Universal Studios launched a multimedia franchise , which now includes video games , theme park rides , an animated television series , and a stage musical .
Keller and Nelson have argued that even if past and future objects do not exist, there can still be definite truths about past and future events, and thus it is possible that a future truth about a time traveler deciding to travel back to the present date could explain the time traveler's actual appearance in the present; [88] these views are ...
