"Fantasy is the impossible made probable. Science Fiction is the improbable made possible."
95% of the plants dying
A study reveals that over the long term the sun is getting brighter by about 1 percent for every 100 million years. It might not sound like much, but as the heat is turned up, CO2 levels in the atmosphere will fall as a result of those heat dependent chemical reactions. In about 500 million years' time, CO2 levels will have fallen to just over 40 per cent of today's level. Consequently, Most plants will struggle to get enough of the gas for photosynthesis. 'About 95 per cent of plant species will start to get into trouble. Pine, fir and tropical forests will give way to grasslands, shrubs and cacti that thrive on relatively low levels of CO2."
Twice round the galaxy
In 678 million years, our Sun, and its solar system, will have orbited three times around the entire Milky Way Galaxy, since the dawn of humanity.
One Quattuordecillion Years From Now: Protons and neutrons decay
Although we think of protons as being stable particles they are actually subject to decay on extremely long time scales. The half-life of a proton is uncertain (because it's so long) but it's in the neighborhood of [10 to the power of 45] years.
One Sexdecillion Years From Now
The total mass of the universe is somewhere between 200 and 500 sexdecillion kilograms.
In the coming times, we may frequently witness such news which is a result of Realistic Speculation about possible future events, based solidly on adequate knowledge of the real world, past and present, and on a thorough understanding of the nature and significance of the scientific method.
Science fiction expresses the dreams that, varied and modified, later becomes the visions and then the realities in scientific progress. Unlike fantasy they present probabilities in their basic structure and create a reservoir of imaginative thought that sometimes can inspire more practical thinking. We keep on looking for technologies that are in themselves ingenious and that have the potential to change our established ways of doing things. Best of all, we like technologies that expand our sense of what it might mean to be human. Most of us came to technology through science fiction; our imaginations remain secretly moved by science-fictional ideas. ... Robots first appeared in Karel Capek's play R.U.R. in 1921. Indeed, it is more useful to ask, What hasn't SF predicted? But the prescriptive power of science fiction has functioned both positively and negatively. Older computer scientists and electrical engineers such as Marvin Minsky and Seymour Cray, born in the mid-1920s, pursued a vision of humanlike artificial intelligence and mainframe computing popularized by science fiction after World War II.
The world of Science Fiction
Science fiction is a modern genre. The feature that distinguishes science fiction from earlier speculative writings and other contemporary speculative genres such as fantasy and horror. The genre formally emerged in the West, where the social transformations wrought by the Industrial revolution first led writers and intellectuals to extrapolate the future impact of technology. By the beginning of the 20th century, an array of standard science fiction "sets" had developed around certain themes, among them space travel, robots, alien beings, and time travel. The customary "theatrics" of science fiction include prophetic warnings, utopian aspirations, elaborate scenarios for entirely imaginary worlds, titanic disasters, strange voyages, and political agitation of many extremist flavours, presented in the form of sermons, meditations, satires, allegories, and parodies-exhibiting every conceivable attitude toward the process of techno-social change, from cynical despair to cosmic bliss.
Subgenres of Science fiction
Hard science fiction, or "hard SF", is characterized by rigorous attention to accurate detail in quantitative sciences, especially physics, astrophysics, and chemistry. Many accurate predictions of the future come from the Hard Science Fiction subgenre, but inaccurate predictions have also come from this category.
Soft" science fiction is the antithesis of hard science fiction. It may describe works based on social sciences such as psychology, economics, political science, sociology, and anthropology.
Military science fiction is set in the context of conflict between national, interplanetary, or interstellar armed forces; the primary viewpoint characters are usually soldiers.
- A setting in the future or in an alternative time line.
- The discovery or application of new scientific principles.
Time travel is the concept of moving backwards and/or forwards to different points in time, in a manner analogous to moving through space. Additionally, some interpretations of time travel suggest the possibility of travel between parallel realities or universes. Although time travel has been a common plot device in fiction since the 19th century, and one-way travel into the future is arguably possible given the phenomenon of time dilation in the theory of relativity, it is currently unknown whether the laws of physics would allow backwards time travel. Any technological device, whether fictional or hypothetical, that is used to achieve two-way time travel is known as a time machine.
Nanotechnology refers broadly to a field of applied science and technology whose unifying theme is the control of matter on the atomic and molecular scale, normally 1 to 100 nanometers, and the fabrication of devices within that size range. It is a highly multidisciplinary field, drawing from fields such as applied physics, materials science, colloidal science, device physics, supramolecular chemistry, and even mechanical and electrical engineering Nanotechnology can be seen as an extension of existing sciences into the nanoscale, or as a recasting of existing sciences using a newer, more modern term.
Faster-than-light communications and travel refer to the propagation of information or matter faster than the speed of light. "True" FTL, in which matter exceeds the speed of light in its own local region, is considered to be impossible by the physics community because of the special theory of relativity, which prohibits a particle with subluminal velocity to accelerate to, or exceed, the speed of light in a vacuum. On the other hand, what some physicists refer to as "apparent" or "effective" Faster Than Light is the hypothesis that unusually distorted regions of spacetime might permit matter to reach distant locations faster than light taking the "normal" route (though not faster than light moving through the distorted region).
A robot is a mechanical or virtual, artificial agent. It is usually an electromechanical system, which, by its appearance or movements, conveys a sense that it has intent or agency of its own. A typical robot has some degree of intelligence, ability to make choices based on the environment, or automatic control/ preprogrammed sequence. The word robot can refer to both physical robots and virtual software agents, but the latter are usually referred to as bots to differentiate.
- A setting in outer space or involving aliens or unknown civilizations.
- Political or social systems different from those of the known present or past.
With the new scientific and technical developments in order to prognosticate freely the techno-social changes, we may experience a seemingly endless variety of staggering scientific feats, but a large class of people will not be surprised at anything. They will have been through it all before in fictional form, and will not be too paralyzed with astonishment to try to cope with contingencies as they arise.
