Gravity is a 2013 science fiction thriller film directed by Alfonso Cuarón, who also co-wrote, co-edited, and produced the film.It stars Sandra Bullock and George Clooney as American astronauts who attempt to return to Earth after the destruction of their Space Shuttle in orbit.
3 Body Problem is an American science fiction television series created by David Benioff, D. B. Weiss and Alexander Woo and the third streaming adaptation of the Chinese novel series Remembrance of Earth's Past written by former computer engineer Liu Cixin.
Conversely, as two massive objects move towards each other, the motion accelerates under gravity causing an increase in the (positive) kinetic energy of the system and, in order to conserve the total sum of energy, the increase of the same amount in the gravitational potential energy of the object is treated as negative.
Cosmic Sin is a 2021 American science fiction action film [4] directed by Edward Drake. The film stars Bruce Willis, Frank Grillo, Brandon Thomas Lee, Corey Large, Perrey Reeves, C.J. Perry, Lochlyn Munro, and Costas Mandylor. [5] Cosmic Sin was released in the United States on March 12, 2021, by Saban Films.
The gravitational potential (V) at a location is the gravitational potential energy (U) at that location per unit mass: =, where m is the mass of the object. Potential energy is equal (in magnitude, but negative) to the work done by the gravitational field moving a body to its given position in space from infinity.
The gravitational potential energy is the potential energy an object has because it is within a gravitational field. The magnitude of the force between a point mass, M {\displaystyle M} , and another point mass, m {\displaystyle m} , is given by Newton's law of gravitation : [ 3 ] F = G M m r 2 {\displaystyle F={\frac {GMm}{r^{2}}}}
For a few days in October 2023, the capital of the science fiction world was Chengdu, China. Fans traveled from around the world as Worldcon, sci-fi ’s biggest annual event, was held in the ...
Neutron star mergers, and their potential to cause extinction events at interstellar distances due to the enormous amounts of radiation released, also feature on occasion. Neutronium, the degenerate matter that makes up neutron stars, often turns up as a material existing outside of them in science fiction; in reality, it would likely not be ...
