The Universe

By FilipR.
  • The Big Bang

    A large explosion that gave birth to all space, time, and matter. It released so much energy while exploding that it's still expanding today.
  • The Universe Shaped

    One millionth of a second after "The Big Bang" the Universe starts to expand and it starts to get shaped. As the particles expand the areas closer to the center start to become less dense and they also start to cool off.
  • The Basic Elements Formed

    Things like protons and neutrons crashed together to make the first nuclei. Hydrogen, helium, and lithium were formed. In about 300,000 years the nuclei might have the ability to sustain electrons in their electron shells.
  • The Radiation Era

    During this era radiation took form. Things like x-rays, UV, Gamma, microwave, and radio became transmited throughout the entire universe. As the universe expands the wavelenghts stretch out.
  • The Era of Matter Domination

    As the universe expands the wavelenghts in lght stretch out and matter seems to be unfazed. Some neutrons become electrons and they fix themselves with the hydrogen, helium, and lithum nuclei to make atoms.
  • The Birth of Stars and Galaxies

    As the hot ring of the expanding universe gets farther away from the center the cooling and densing from the matter condesnses and groups. They clump together which cause gravity pulling more and more atoms to the particles. After some time enough atoms are gathered and ignite int stars. These then use their gravity to make galaxies.
  • The Birth of the Sun

    The Sun was made on the outer rings of the Milky Way Galaxy. It is composed of gasses that are being pulled in a spiraling motion.
  • Earth Life Forms

    As the Earth is being maded it slowly starts to cool even though thousands of meteors impact it every day. It cools to a point were an atmosphere is made and where single celled microorganisms florish in the Earths many volcanic ecosystems.
  • Primitive Animals Appear

    The single celled microorganisms evolve into things like flat wroms or jelly fish. In the next 570 million years shelled creatures will arive.
  • The First Mammals Appear

    These new mammals evolved from reptiles and other aquatic organisms that developed mammilian traits. Things like orginized bones, ex. inner ear, were developed.
  • The Dinosaurs Extinction

    Once the dinosaurs are about done on there turn for being the dominate species an astroid hits the Earth in Northern Mexico which causes every dinosaur on the planet to die. Small mammals start to have a chance at life and they begin to diversify.
  • Homo Sapiens Evolved

    The human's longest ansector came from Africa and it descended from apes.
  • A Supernova Explodes

    A star explodes in a dwarf galaxy known as the Large Magellanic Cloud that lies just beyond the Milky Way. It was a blue supergiant 25 times more big than the Sun.The explosion gives off all of the stars elements and once the elements scatter they are picked up in cosmic dust clouds and they become heavier elements like gold or lead.
  • A Crab Supernova Appears

    Chinese, Japanese, and Native American people talked about the appearance of a supernova. It wasn't writen in Europe, most likely as a consequence of lack of study of nature during the Dark Ages. The remainss of this explosion are able to be see in the Crab Nebula. Inside the nebula, astronomers have found a pulsar, the ultra-dense remains of a star that exploded.
  • Galileo Builds the First Telescope

    Five years after the appearance of the great supernova of 1604, Galileo builds his first telescope. He sees the moons of Jupiter, Saturn's rings, the phases of Venus, and the stars in the Milky Way. He publishes the news the following year in "The Starry Messinger."
  • Isaac Newton Describes Gravity

    When Newton was only 23 years old he understood that gravity holds people onto the Earth and it is also the reason why the moon acts the way it does. These laws were now set to govern the universe.
  • Albert Einstein Publishes his Theory of Relitivity

    He described how the speed of light is the ultimate speed limit in the universe and it is the key to binding all other theories of space and time to unlock the secrets of spacetime.
  • Edwin Hubble Discovers that the Universe is Expanding

    Edwin Hubble discovers that the universe is expanding. He uses a 100in. telescope to help him in his research in things like the farther galaxies are from the center of the universe the more red they become because of the heat left over from when the universe expanded there.
  • Discorery of Quasars

    Allan Sandage and Thomas Matthews find sources of intense radio energy, calling them Quasi Stellar Radio Sources. Four years later, Maarten Schmidt would discover that these sources lie at the edge of the visible universe. In recent years, astronomers have realized that they are gigantic black holes at the centers of young galaxies into which matter is heated to high temperatures and glows brightly as it rushes in.
  • Discovery of Microwave Background Radiation

    Scientists at the Bell Telephone Laboratories discovered microwave radiation that bathes the earth from all directions in space. This radiation is the afterglow of the Big Bang.
  • Discovery of Pulsars

    Pulsars were the first known examples of neutron stars, extremely dense objects that form in the wake of some supernovae. The crab pulsar, the tiny star in the middle of the Hubble Space Telescope, is the remnant of the bright supernova recorded by Native Americans and cultures around the world.
  • Light from Supernova 1987A Reaches Earth

    The light from this star first hits Earth after 170,000 years of burning. The US and Japan were the first countries to detect it. Also things called neutrions were released and were sensed to tell where the supernova was.
  • Hubble Space Telescope Launched1990 A.D.

    The twelve-ton telescope, equipped with a 94-inch mirror, is sent into orbit by astronauts aboard the space shuttle Discovery. Within two months, a flaw in its mirror is discovered, placing in jeopardy the largest investment ever in astronomy.
  • The Big Bang Confirmed

    Astronomers used Cosmic Background Explorer satellite (COBE) to detect microwave radiation in the universe and all the data transmited gave 100% evidence of "The Big Bang Theory".
  • Hubble Space Telescope Repaired

    Astronauts aboard the space shuttle Endeavor succeed in correcting Hubble's flawed optics, ushering in a spectacular new age of astronomy from space. Hubble's greatest legacy so far.
  • The Stellar Era Ends

    Astronomers assume that the universe will gradually wither away. During the Stelliferous Era, from 10,000 years to 100 trillion years after the Big Bang, most of the energy generated by the universe is in the form of stars burning hydrogen and other elements in their cores.
  • The Degenerate Era

    At this time all of the visible mass in the universe is released from degenerated stars that have collapsed into neutron stars, black holes, or have become white dwarfs. Energy in this time is made from proton decay or from particale annihilation.
  • The Black Hole Era

    After proton decay starts to stop all that will be left are black holes of different masses that are actively evaporating.
  • The Dark Era

    After there is no more proton decay and black holes have evaporated only the waste products from these processes remain. Mostly photons of colossal wavelength, neutrinos, electrons, and positrons that came form proton decay or from black hole evaporation. For all intents and purposes, the universe as we know it has dissipated.
