i am studiyng about Extraterrestrial life ,called alien life , is life that occurs outside of Earth and that probably did not originate from Earth . These hypothetical life forms may range from simple prokaryotes to beings with civilizations far more advanced than humanity . ^{[1] [2]} The Drake equation speculates about the existence of intelligent life elsewhere in the universe. The science of extraterrestrial life in all its forms is known as exobiology .

The concept of extraterrestrial life, and particularly extraterrestrial intelligence, has had a major cultural impact, chiefly in works of science fiction . Over the years, science fiction communicated scientific ideas, imagined a wide range of possibilities, and influenced public interest in and perspectives of extraterrestrial life. One shared space is the debate over the wisdom of attempting communication with extraterrestrial intelligence. Some encourage aggressive methods to try for contact with intelligent extraterrestrial life. Others—citing the tendency of technologically advanced human societies to enslave or wipe out less advanced societies—argue that it may be dangerous to actively call attention to Earth.

BLACK HOLES

A black hole is a region of spacetime exhibiting such strong gravitational effects that nothing—not even particles and electromagnetic radiation such as light —can escape from inside it.The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole. The boundary of the region from which no escape is possible is called the event horizon . Although the event horizon has an enormous effect on the fate and circumstances of an object crossing it, no locally detectable features appear to be observed. In many ways a black hole acts like an ideal black body , as it reflects no light. Moreover, quantum field theory in curved spacetime predicts that event horizons emit Hawking radiation , with the same spectrum as a black body of a temperature inversely proportional to its mass. This temperature is on the order of billionths of a kelvin for black holes of stellar mass , making it essentially impossible to observe.

SPACE SUIT.

A space suit is a garment worn to keep a human alive in the harsh environment of outer space , vacuum and temperature extremes. Space suits are often worn inside spacecraft as a safety precaution in case of loss of cabin pressure , and are necessary for extravehicular activity (EVA), work done outside spacecraft. Space suits have been worn for such work in Earth orbit, on the surface of the Moon , and en route back to Earth from the Moon. Modern space suits augment the basic pressure garment with a complex system of equipment and environmental systems designed to keep the wearer comfortable, and to minimize the effort required to bend the limbs, resisting a soft pressure garment's natural tendency to stiffen against the vacuum. A self-contained oxygen supply and environmental control system is frequently employed to allow complete freedom of movement, independent of the spacecraft.

im  a mechanical engineering student and a budding inventor,  already being involved in many engineering projects , i soon will be desinging armours and protection of spacecrafts. the great scientist stephen hawking himself  congralated me on my hypothesis of black holes when i presented mine.

already into developing life saving engineering solutions , i will be desiging lprotection of space crafts and space suits.im also  into researching in the field of  astronomy , even was mentioned in the magazine called all about space. and im also doing research in astrobiology for extraterrestrial life.

do support me for science and peace
