Origin of the Universe

                     There are many "haka-haka" about the origin of the universe. Maybe some of this is true, but most of that theory are not totally true. Some of the theory is the big bang theory, Black hole, The Inflation Universe Theory and many more. The common theory is the big bang theory because some of the information is true. But we are not sure of that information.
                      There are many scientist debating about the origin of the Universe. Just like the famous scientist named Einstein.
Origin of the Universe - The Big Bang Theory                  Most scientists now believe that the answer to the first part of the question is that the Universe sprang into existence from a singularity -- a term physicists use to describe regions of space that defy the laws of physics. We know very little about singularities, but we believe that others probably exist in the cores of black holes.
               The second part of the question, as to what existed before the Big Bang, has scientists baffled. By definition, nothing existed prior to the beginning, but that fact creates more questions than answers.Once the singularity was created (however it happened), it began to expand through a process called inflation. The Universe went from very small, very dense, and very hot to the cool expanse that we see today. This theory is now referred to as the Big Bang, a term first coined by Sir Fred Hoyle during a British Broadcasting Corporation radio broadcast in 1950.
                     Interestingly, there really wasn’t any sort of explosion or bang as the name suggests, but rather the rapid expansion of space and time. It is like blowing up a balloon, as you blow air in, the exterior of the balloon expands outward.
                      Some of the other theories argue that the Big Bang theory is based on a false premise -- that the Universe is built on an ever expanding space-time. Some, instead, prefer to build theories on a static Universe, which is what was originally predicted by Einstein’s theory of general relativity. Einstein’s theory was only later modified to accommodate the way the Universe appears to be expanding.

Origin of the Universe - The Inflation Universe Theories
            The Big Bang Theory provided an atheistic explanation for the origin of the universe, but its obvious simplicity was subject to multiple attacks. As a result, the original theory is no longer the dominant scientific explanation for the atheistic origin of the universe. While the original Big Bang Theory is now "dead," from its ashes have emerged the various Inflationary Universe Theories

.
Origin of the Universe - Theism vs. Atheism
               In general, theists attribute the origin of the universe to some sort of transcendent, intelligent Designer. Atheists envision a natural, undirected process by which universes spring into existence spontaneously. Prior to the 20th century most atheists believed the universe was eternal. This changed however as discoveries throughout the 20th Century rendered that view untenable. Einstein’s theory of gravity which has been thoroughly validated by extensive experimental confirmation and Hubble’s astronomical observations preclude an eternal universe. We now know beyond a reasonable doubt that the universe began at some point in the finite past. 


Origin of the Universe - Long Ago and Far Away...
           Attempts to exclude a Creator from the "origin of the universe equation" have been long on theoretical calculations and short on common sense. The various models merely move the questions of where, why and how did everything get here to "long ago and far away." Atheists are tenacious in their efforts to ignore the necessity of a First Cause, Intelligent Designer, Creator God. But as Aldous Huxley put it so eloquently, "Facts do not cease to exist because they are ignored." And it seems that atheists must ignore a great deal in order to maintain their atheistic cosmogonic position.



                       The explanation in the top is the explanation of the theory how Universe created or the Origin of the Universe. All we know is only God created all the system the we found anywhere. Maybe scientist did not believed about God so they searching in their own to find the origin of Universe.






Planets in the Solar System

                    There are 9 planets in solar system, one of that is the Earth the place where we live. In the past days it was announced that Pluto is not part already in solar system. Or in other word Pluto is not a planet now. We can consider it as a star. There are eight/nine planet, one of that is the Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.
                    Solar System consist of sun and those celestial object bound to it by gravity, all of which formed from collapse of a giant molecular clouds approximately 4.6 billion years ago. Of the retinue  of object that orbit the sun, most of the mass is contained within eight  relatively solitary planets whose orbit are most circular and lie within a nearly flat disc called the ecliptic plane.Mercury, Venus, Earth and Mars is the four smaller inner planets, it also called the terrestrial planet, are primarily composed of rock and metal. The four outer planets is the Jupiter, Saturn, Uranus and Neptune, also called a gas giant, are composed largely  of hydrogen and helium and are far more massive than the terrestrial.
                   The four inner or terrestrial planets have dense, rocky compositions, few or no moons, and no ring system. They are composed largely of refractory minerals, such as the silicates, which form their crust and mantle, and metals such as iron and nickel, which form their cores. Three of the four inner planets Venus, Earth and Mars have atmosphere substantial enough to generate wether; all have impact crater and tectonic surface features such as rift valley and volcanoes.

MERCURY
            -is almost negligible atmosphere consists of atoms blasted off its surface by the solar wind.Its relatively large iron core and thin mantle have not yet been adequately explained. Hypotheses include that its outer layers were stripped off by a giant impact, and that it was prevented from fully accrediting by the young Sun's energy.
VENUS
            -has no natural satellites. It is the hottest planet, with surface temperatures over 400 C.most likely due to the amount of greenhouse gases in the atmosphere.No definitive evidence of current geological activity has been detected on Venus, but it has no magnetic field that would prevent depletion of its substantial atmosphere, which suggests that its atmosphere is regularly replenished by volcanic eruptions.



 EARTH
         -is the largest and densest of the inner planets, the only one known to have current geological activity, and is the only place in the Solar System where life is known to exist. Earth's atmosphere is radically different from those of the other planets, having been altered by the presence of life to contain 21% free oxygen. It has one natural satellite, the moon, the only large satellite of a terrestrial planet in the Solar System.
 MARS
           - (1.5 AU from the Sun) is smaller than Earth and Venus (0.107 Earth masses). It possesses an atmosphere of mostly carbon dioxide with a surface pressure of 6.1 millibars (roughly 0.6 percent that of the Earth's). Its surface, peppered with vast volcanoes such as Olympus Mons and rift valleys such as Vallie's Marinesis , shows geological activity that may have persisted until as recently as 2 million years ago. Its red colour comes from iron oxide (rust) in its soil. Mars has two tiny natural satellites thought to be captured asteroids.
                  The four outer planets, or gas giants, collectively make up 99 percent of the mass known to orbit the Sun. Jupiter and Saturn are each many tens of times the mass of the Earth and consist overwhelmingly of hydrogen and helium; Uranus and Neptune are far less massive and possess more ices in their makeup. For these reasons, some astronomers suggest they belong in their own category, “ice giants.” All four gas giants have rings, although only Saturn's ring system is easily observed from Earth. The term outer planet should not be confused with superior planet  which designates planets outside Earth's orbit and thus includes both the outer planets and Mars.
JUPITER
          - strong internal heat creates a number of semi-permanent features in its atmosphere, such as cloud bands and the Great Red spot.
SATURN
           - has 60% of Jupiter's volume, it is less than a third as massive, at 95 Earth masses, making it the least dense planet in the Solar System. The rings of Saturn are made up of small ice and rock particles.
URANUS
              -(19.6 AU), at 14 Earth masses, is the lightest of the outer planets. Uniquely among the planets, it orbits the Sun on its side; its exile tilt is over ninety degrees to the ecliptic. It has a much colder core than the other gas giants, and radiates very little heat into space.
NEPTUNE
            -is accompanied in its orbit by a number of minor planet, termed Neptune Trojan, that are in 1:1 resonance with it.
                 


                     This is the eight planet in the Solar system. Can you observe that Pluto is considered not a planet. that is the list of the planet can be found in the solar system.
