Masters Of The Universe Origins

    There are following modern theories put forward to explain the origin and the evolution of the universe.

  THE BIG-BANG THEORY:

    It is the most acclaimed theory proposed by Georges Lemaitre of Belgium in the 1930s and later strongly evidenced by George Gamow, which explained the modern big bang theory.

  CONCEPT OF BIG-BANG THEORY:

    According to this theory, at the beginning of the universe, the whole matter of the universe including its size and matter and radiation was once concentrated in an extremely dense hot fireball.

    At about 15 billion years ago, vast explosions occurred, and the primeval atom distant grated giving rise to space and time and the expansion of the universe continues.

    It will continue today and it will further continue to go.

    The expansions of matters further formed galaxies and these galaxies are continuously expanding and moving away from each other in an accelerated velocity and in the process cooling the universe.

  WHAT IS RED SHIFT THEORY:

    Light is formed from the sand of colors, called the spectrum.  Violet color has the shortest wavelength and lies at another end.

  CONCEPT OF RED SHIFT THEORY:

    The movement of a star or galaxy affects its light as seen by the observer.  When the star is approaching the observer, the light shifts to the blue end of the spectrum and red end.

    When the star deceives away, this is known as more dop effect or Doppler shift.  This shows that the galaxies are moving away with a state of the rapid and accelerated state of expansion.  The astronomical observation was thus named redshift.

  STEADY STATE THEORY AND WHAT IT SAYS:

    Bondi, gold and Fred Hoyle developed this theory.  According to this theory, the number of galaxies in the observable universe is constant and new galaxies are continuously created out of empty space.

    Which fill up the gaps caused by those galaxies, which have crossed the boundary of the observable universe.  As a result of its the overall size of the mass of the observable universe remains constant.

    Thus, a steady state of the universe is not disturbed at all.

  CONCEPT OF PULSATING THEORY:

    According to this theory, the universe is supposed to be expanding and contracting alternatively i.e, pulsating or oscillating at present the universe is expanding.

    According to this theory, this is possible that certain time, the expansion may be stopped by the gravitational pull and get contracted again.  After it has been contracted it will explode again and this alternative expansion and contraction give rice to the pulsating universe.
