Timeline of the far future

Timeline of the far future
What the Earth might look like seven billion years from now, after the Sun has entered the red giant phase. While predictions of the future can never be absolutely certain,[1] present scientific understanding in various fields has allowed a projected course for the farthest future events to be sketched out, if only in the broadest strokes. These fields include astrophysics, which has revealed how planets and stars form, interact and die; particle physics, which has revealed how matter behaves at the smallest scales; and plate tectonics, which shows how continents shift over millennia. All predictions of the future of the Earth, the Solar System and the Universe must account for the second law of thermodynamics, which states that entropy, or a loss of the energy available to do work, must increase over time. Stars must eventually exhaust their supply of hydrogen fuel and burn out. Key[edit] Future of the Earth, the Solar System and the Universe[edit] Astronomical events[edit] See also[edit]

KIC 12557548 History of detection[edit] The existence of the planet was first evidenced in data collected by the Kepler spacecraft. However, the light curve of the star, a graph of its stellar flux versus time, showed that while there were regular drops in stellar flux approximately every 15 hours, the amount of light being blocked covered a wide range, from 0.2% to 1.3% of the starlight being blocked.[2] Rappaport et al. (2012) proposed various possible phenomena which may have caused the anomalies in the light curve, including two planets orbiting each other,[6] and an eclipsing binary orbiting the star in a larger triple-star system.[2] However, the authors found the hypothetical binary planet system to be unstable[2] and the latter scenario to be poorly supported by the data collected by Kepler.[2]

Medical astrology Medical astrology (traditionally known as Iatromathematics) is an ancient medical system that associates various parts of the body, diseases, and drugs as under the influence of the sun, moon, and planets, along with the twelve astrological signs. Each of the astrological signs (along with the sun, moon, and planets) is associated with different parts of the human body. The underlying basis for medical astrology, astrology itself, is considered to be a pseudoscience or superstition as there is no scientific basis for its core beliefs.[1] Overview[edit] History of the Earth The history of the Earth concerns the development of the planet Earth from its formation to the present day.[1][2] Nearly all branches of natural science have contributed to the understanding of the main events of the Earth's past. The age of Earth is approximately one-third of the age of the universe. An immense amount of biological and geological change has occurred in that time span. The first life forms appeared between 3.8 and 3.5 billion years ago. The earliest evidences for life on Earth are graphite found to be biogenic in 3.7 billion-year-old metasedimentary rocks discovered in Western Greenland[3] and microbial mat fossils found in 3.48 billion-year-old sandstone discovered in Western Australia.[4][5] Photosynthetic life appeared around 2 billion years ago, enriching the atmosphere with oxygen. Life remained mostly small and microscopic until about 580 million years ago, when complex multicellular life arose.

List of human positions - Wikipedia "Posing" redirects here. For municipality in Bavaria in Germany, see Pösing. Human positions refer to the different physical configurations that the human body can take. There are several synonyms that refer to human positioning, often used interchangeably, but having specific nuances of meaning.[1] Basic positions[edit] While not moving, a human is usually in one of the following basic positions: List of timelines From Wikipedia, the free encyclopedia This is a list of timelines currently on Wikipedia. §Types[edit] §General timelines[edit] §History[edit]

Astrological symbols Astrological symbols are images used in various astrological systems to denote relevant objects. A number of such images are shown below. History and origin[edit] Symbols for the classical planets, zodiac signs, aspects, lots, and the lunar nodes appear in the medieval Byzantine codices in which many ancient horoscopes were preserved.[1] In the original papyri of these Greek horoscopes, there were found a circle with the glyph representing shine( ) for the Sun and a crescent for the Moon.[2] The written symbols for Mercury, Venus, Jupiter, and Saturn have been traced to forms found in late Greek papyri.[3] The symbols for Jupiter and Saturn are identified as monograms of the initial letters of the corresponding Greek names, and the symbol for Mercury is a stylized caduceus.[3] A.

Future of the Earth Conjectured illustration of the scorched Earth after the Sun has entered the red giant phase, 7 billion years from now.[1] During the next four billion years, the luminosity of the Sun will steadily increase, resulting in a rise in the solar radiation reaching the Earth. This will cause a higher rate of weathering of silicate minerals, which will cause a decrease in the level of carbon dioxide in the atmosphere. Chartjunk An example of a chart containing gratuitous chartjunk. This chart uses a large area and a lot of "ink" (many symbols and lines) to show only five hard-to-read numbers, 1, 2, 4, 8, and 16. Chartjunk refers to all visual elements in charts and graphs that are not necessary to comprehend the information represented on the graph, or that distract the viewer from this information.[1][2][3] Markings and visual elements can be called chartjunk if they are not part of the minimum set of visuals necessary to communicate the information understandably.
