Krypton (planet) - Krypton (planet) The fictional planet Krypton was the birthplace of Kal-El, better known as Superman. The planet, presumably named after the chemical element Krypton, was created by Jerry Siegel and Joe Shuster for the syndicated daily newspaper strip in 1939 and later brought into the comic books. Krypton no longer exists in the DC Comics universe, as it exploded as a result of highly unstable geological conditions. The entire civilization and race of Krypton perished in the explosion, except for one sole survivor: the baby Kal-El, who was placed in an escape rocket by his father Jor-El and sent to the planet Earth. "Old Krypton" There have been two versions of Krypton (so far) in the history of Superman. The first version developed gradually over the.

Kryptonite - redefined by writer John Byrne, the pre-Crisis DC Universe was home to a variety of elements called Kryptonite. Kryptonite was produced from the material of Superman's home planet Krypton, when it was destroyed in an explosion. Kryptonite is usually found in the form of a glowing green rock or metal, but crystalline forms have also made appearances (most notably Jewel Kryptonite, see below) along with different-colored variants such as red kryptonite. These different forms may represent multiple allotropes or isotopes of Kryptonite, or a more exotic variation in composition based on currently unknown particles. Near the end of the run of the Pre-Crisis Superman, all known Kryptonite on Earth was transmuted into iron, but Kryptonite can be synthetically manufactured by a variety of unknown means and additional material left over from.

Planets in science fiction - themes of science fiction. During the first decades of science fiction, Mars was the most common planet and the most romanticized of our solar system whose surface conditions seemed closest to being amenable to life. Percival Lowell's idea about canals of Mars was taken at face value then. Currently Mars is depicted mainly as a target of terraforming. See Mars in fiction for more details on the red planet's numerous roles. During the early-to-mid 20th century, Venus was also a popular subject. Venus is very similar to Earth in its size and surface gravity, and its surface is hidden by a thick cloud layer. Venus was usually depicted as a warm, wet, jungle- and marsh-covered world where life was plentiful, with often thinly-veiled allegories of the European colonization of Africa. Venus.

Discoveries of the chemical elements - believer in phlogiston, he didn't realise that he had prepared a new element, and thought that he had managed to prepare air free from phlogiston ("de-phlogisticated air"). However, he was the first to isolate oxygen, even if he didn't realise what he had: Oxygen 1771 Joseph Priestley Chlorine 1774 Karl Wilhelm Scheele Manganese 1780? Hjelm Molybdenum Tellurium 1782 Mueller von Reichenstein Tungsten 1783 The recent discovery of the new planet Uranus by William Herschel had caused a stir, so the newly discovered metallic element was christened uranium in its honour. Uranium 1789 Martin Heinrich Klaproth Zirconium Strontium 1793 Martin Heinrich Klaproth Titanium 1797 Martin Heinrich Klaproth Yttrium Chromium Columbium Tantalum The next element was discovered just after the discovery of a new class of astronomical objects: the new element was named.
Clark Kent - Smallville while Jeb rode as the leader of a band of bandits. Eventually, he discovered he had a son out of wedlock from years ago and allowed him to join his gang. Unfortunately, he turned out to be a murderous sociopath and Jeb approached his estranged brother to arrange a trap to stop his son. Unfortunately in springing the trap, the son mortally wounded his father before being killed himself and Jeb fully reconciled with Nate before dying. Nate remained in Smallville and the Kents have stayed for generation up to Jonathon and Martha who discovered Kal-El who arrived from the destroyed Planet Krypton..

Superman - Synopsis The story of Superman's origin is a science-fiction update of the common origin story of various culture heroes eg. Gilgamesh, Moses, and Jesus, who, to save them from death as babies, are spirited away from the place where they are threatened. Superman was born as Kal-el on the planet Krypton. While still a baby he was put into a spaceship alone by his father, Jor-El, and his mother, Lara. The ship launched moments before his home-planet exploded. His spaceship landed on Earth. He was adopted by a family in Smallville, Kansas, and was raised there until, as an adult, he moved to Metropolis. In the original series of Superman comics (1940s to 1985), Superman is the real person, and Clark Kent is a phony front he presents to the world,.
Supergirl - published by DC Comics. During the 1950s, the character of Supergirl was introduced as the last survivor of a city of the planet Krypton, which had somehow survived the explosion of the planet and drifted through space for about fifteen years. When the inhabitants of the colony were slain by Kryptonite, Supergirl (whose Kryptonian name was Kara Zor-El) was sent to Earth to be raised by Superman. Throughout the 1950s Supergirl's existence on Earth was kept a secret, but she was revealed to the world in the 1960s. She maintained close ties with her cousin Superman while pursuing her own career as a superhero. She took on the Earth name of "Linda Lee" for her secret identity. During the Crisis on Infinite Earths, Supergirl bravely sacrificed her life to save the.
Superman (movie) - by Richard Donner and executive produced by Alexander Salkind, with music by John Williams. Warning: Wikipedia contains spoilers. As in the comic series, Superman is the last survivor of the planet Krypton who as an infant was sent to Earth by his parents Jor-El (played by Marlon Brando for a payment, notorious at the time, of $4 million for eight minutes' screen time) and Lara. He's raised by Jonathan and Martha Kent in Smallville and upon reaching adulthood takes a job as a reporter for the Daily Planet newspaper in Metropolis. It is in Metropolis that he first appears publicly as Superman. He gives an interview to Lois Lane and comes to the attention of Lex Luthor, a criminal mastermind who has secret headquarters in Metropolis' subway system. Luthor has reprogrammed.
Reciprocal System of Theory - because of these violations of the energy conditions, caused in general by the coupling of scalar fields to gravity, "the conflict between quantum physics and gravity is now becoming acute," and he suggests that physicists "banish scalar fields from [their] theories" altogether, as the simplest solution to the problem, though he admits that it would not be the easiest way out due to the crucial role scalar fields play in many important physical theories today. In contrast to the turmoil that the evidence of dark energy has induced in the state of affairs in mainstream physics, a similar outward, gravity-like motion has always been an integral part of the RST from the beginning, and is a major component in the RST's calculations and explanations of both the large-scale structure of the.
Weights and measures - up to this day. Just to underline the importance of agreed units, the NASA Mars Polar Lander in December 1999 crashed on the planet Mars instead of staying in orbit, due to miscommunications about the value of forces: different people used different assumptions about the unit of measure (newton versus pound). Enormous amounts of effort, time and money were wasted.

Phantom Zone - shared universe retcon with Crisis on Infinite Earths in the 1980s. It was discovered by Jor-El used on the planet Krypton as a method of imprisonment of criminals. The Phantom Zone criminals first appeared in the Superboy stories and soon began appearing in the Superman stories. The inmates of this dimension are cast into the dimension and reside in a featureless state of existence from which they observe the regular dimension clearly. They do not age, not need any substinance and largely not affected by the regular dimension. As such, they survived the destruction of Krypton and focused their attention on Earth seeing as how most of the surviving Kryptonians now reside there. Most have a particular grudge against Superman seeing as how his father created the method of their own.
Mon-El - stories, the fictional character Mon-el is a Daxamite from the planet Daxam. He landed on Krypton and was given a map to Earth. He then went into suspended animation. After a few years he landed and met Superboy. They became good friends. Under Earth's yellow sun he had powers like Superman's. Daxamites are affected by lead and Kryptonite in the same way as Kryptonians. After heavy lead exposure he was dying, so Superboy put him in the Phantom Zone to stop his dying. In the 30th century Brainiac5 created an antidote to lead and released him so Mon-el then joined the Legion of Super-Heroes..
Lex Luthor - later a back-story finally filled in how Luthor lost his hair, and that Luthor's hatred of Superman stemmed from a childhood incident where a teenaged Superboy used his superbreath to extinguish a fire that had broken out in Luthor's lab. Unfortunately for him, during this rescue attempt chemicals were spilled, causing Luthor to go prematurely bald and destroying Luthor's successful attempt to create new life through chemistry which might have also cured Superboy of his susceptibility to kryptonite. Luthor attributed Superboy's acts to jealousy on the Kryptonian's part and vowed revenge. First he tried to show Superboy with a series of grandiose technological projects, only to have them all go dangerously out of control and requiring Superboy's intervention. Unwilling to accept personal responsibility for this accidents, Lex rationalized that Superboy was.
