Dark matter  is an unidentified type of matter  distinct from dark energy ,  baryonic matter  (ordinary matter),  and neutrinos . It comprises approximately 27% of the  mass and energy  in the   observable universe .  The name refers to the fact that it does not emit or interact with electromagnetic radiation , such as light, and is thus invisible to the entire electromagnetic spectrum .  Although dark matter has not been directly observed, its existence and properties are inferred from its gravitational effects such as the motions of visible matter, gravitational lensing , its influence on the universe's large-scale structure , and its effects in the cosmic microwave background . Dark matter is transparent to    electromagnetic radiation  and/or is so dense and small that it fails to absorb or emit enough radiation to be detectable with current imaging technology.                                  Estimates of masses for galaxies and larger structures via dynamical and 

Tectonic plates are pieces of earth's crust and uppermost mantle,together referred to as the lithosphere.The plates are around 100 km (62 mi)thick and consist of two principal material:ocean -crust(also called sima from silicon magnesium) and continental crust (sial from silicon and aluminium).The composition of the two types of crust differs markedly,with basaltic rocks ("mafic") dominating oceanic crust,while continental crust consists principally of lower density granitic rocks. Geologists generally agree that the following tectonic plates exist on the earth's surface with roughly definable boundaries.Tectonic plates are sometimes subdivided into three fairly arbitrary categories: major (or primary) plates,minor (or secondary) plates, and micro (or tertiary) plates. Major plates : These plates comprise the bulk of  the continents and the pacific ocean .A major plate is any plate with an area greater than 20 million km. Minor plates : These smaller

The concept of supercontinent was first proposed by the Alfred Wegener (His full name is Alfred-Lothar-Wegener) in the year of 1912. He was born on 1 November 1880. He is a German polar researcher, Geophysicist, and Meteorologist. The reason behind he proposed this concept is he found some fossil's which lived on the earth. In all the continents but the distance between the continents are so long. That is the reason he proposed his concept of continental drift.  This continental drift was controversial and not widely accepted because he did not prove that how the continents are moved due to this reason every not accepted until the 1950's. After tectonic plates was discovered based on this tectonic plates the continents are moved. now we assume that how the modern continents was placed. Alfred-Lothar-Wegener FOSSIL Every 300-500 Million years the supercontinent was formed. In 300 Million years ago one supercontinent was formed it was named as PANGAEA. The word P

                                 Maglev trains need  cost Expensive infrastructure. That is nothing but it wants high-power supply and copper coils.To reduce these things the new transpotation technology is developed by SPACEX organization.It is low-cost  and it is very faster in speed while comapre to Maglev tarins. This technology is named as HyperLoop.The speed of this hyper loop is 1200 km/h.                                                              The reason behind  they named this to HyperLoop is train travel in the  tube's.All the infrastructure which is needed to this technology is placed in tubes.The first Hyper Loop preliminary design was released in the year of 2013 between Los Angeles to San Francisco area.In the year of 2016 MAY 13 it was successfully tested in Nevada(USA).    HYPER LOOP           Now so many of the countries were proposing this Hyper Loop technology.The European routes was put forward in JANUARY 2016 Between Amsterdam to Paris notional

Watson is an IBM supercomputer that combines artificial intelligence ( AI ) and sophisticated analytical software for optimal performance as a “question answering” machine. The  super computer   is named for   IBM ’s founder, Thomas J. Watson. The Watson supercomputer processes at a rate of 80  teraflops  (trillion floating-point operations per second). To replicate (or surpass) a high-functioning human’s ability to answer questions, Watson accesses 90 servers with a combined data store of over 200 million pages of information, which it processes against six million logic rules. The device and its data are self-contained in a space that could accommodate 10 refrigerators. Watson's key components include: Apache  UIMA (Unstructured Information Management Architecture)  frameworks , infrastructure  and other elements required for the analysis of  unstructured data . Apache's  Hadoop , a free,  Java -based programming framework that supports the processing of large data
