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.

Weather and Climate in Philippines

                     Weather and climate here in Philippines is not like other country. We all know that there are four season of weather: spring, summer, winter and fall or autumns. But here in the Philippines we only have three season it is the hot season (tag araw or tag init), rainy season (tag ulan) and cold season (tag lamig). Weather is different from climate, if we say weather it always tackle about  the condition of the atmosphere over a short of period of time. While climate is how the atmosphere behaves over relatively long period of time.
                       There are three distinct kind of climate: temperature, humidity and rainfall. Temperature refer to the temperature every month, it measure the coolest and heatest month of the while year. Humidityrefer to the moisture content of the atmosphere due to high temperature and the surrounding bodies of water. The combination of warm temperature and high relative and absolute humidities give rise to high sinsible temperature throughout the archipelago. And the most important climatic element in the Philippines. Rainfall distributed throughout the country varies from one region to another, depending upon the direction of the moisture bearing wind and location of the mountain system.
                       The climate, using temperature and rainfall as bases, the climate of the country can be divided into two major season. The rainy season from June to November and the dry season from December to May. The dry season may be subdivided further into (a)cool dry season from December to February and (b) hot dry season from March to May.




                         El Nino and La Nina is also part of the the climate. Weather and Climate is important to us in order us to survive. we are so lucky the we dont suffer any problem in our weather and climate not like other country. Weather and climate have also affect our life.

Importance of Earth Hydrosphere


         Does hydrosphere important to us? What is hydrosphere all about? if there no hydrosphere what would be the possible things that may happened to us? This is some of the question that bother my mind.
           Hydrosphere have an important role in this planet Earth, it help to manipulate the heat comes from the sun so that we cannot suffer an intense heat. We all know that hydrosphere consist of heavenly body of water such us oceans, lakes, rivers, streams, underground and frozen in glaciers. Hydrosphere also called as "water sphere". Ocean current also help to disperse heat. Water take a long time to heat up and also long time to cool down, its help to regulate temperature here on Earth so that they stay within a range that is acceptable for life to exist. Our planet also have water on surface, which is very unique. Only the have this kind of characteristic that why Earth also called "blue Planet" because of the water surrounded it. It made of fresh water like rivers and streams. The use of hydrosphere  to generally lost the heat to the space. Oceans serve to main purpose in the climate system. First, it is the large reservoir  of chemical that can contribute  to the greenhouse effect of the atmosphere, and help to absorb the solar radiation which hit the surface. This reservoir change very slowly limiting  how past the climate can change. Second, it work with atmosphere to redistribute the energy received from the sun such that the heat and lot or many energy is received from the sun transfer to the poles.

                  Hydrosphere not only can hep the planet or protect the planet from the heat coming from the sun, but it help also to the people to survive and exist their life to the better one. Water is so important in mans life, its the major needs of man. We cant live without water. Human use water in many ways like drinking and washing. Drinking water is obviously very important. This is the some of importance of hydrosphere to us.
                                 
                                       In our high school day we topic about the three primary state of matter on Earth it is the solid, liquid and gas.The distance of Earth from the Sun, by fortunate coincidence, is such that the amount of energy arriving at the surface of most of the planet is sufficient to elevate the ambient temperature to levels above the freezing point of water, yet insufficient to cause all of the water to evaporate into the gaseous state. The capacity of water to store large quantities of heat energy heavily influences the nature of the global climate. The presence of large bodies of liquid water and the atmosphere restrict the range of temperature fluctuations on Earth. These conditions have allowed the existence of the fourth component of Earth's system, the biosphere. Hydrosphere main purpose is to protect the Earth by the help of the water consist it. If there no hydrosphere we cant survive because we can directly received the intense heat coming from the sun , and that is very dangerous to us.

The hydrosphere has provide water for our crops. Crops have provided all our nutrient needs since life exist. The hydrosphere also provides us with water to hydrate our body. Without the hydrosphere we would not be living because it is simply how we survive on this earth.

Advantage and disadvantage of Science and Technology

                In our modern world Science and Technology are important,beside there are many people can't live without such gadgets or invention.But we all know that even its important to us but still there are many disadvantage in us,because of this technology we became dependent and also over using this technology can cause a cancer because of the radiation.Even in our environment it may cause damage.All good thing for us have also their side effect.Now we depend machine to do all our household chores and even our schools assignment and activities.Technology is important in order us to communicate  our love ones outside the country.
              Science is the key by which man go anywhere or travel everywhere at any time in the space and even in land or in the air.Its because of the great invention of our intelligent scientist.It is true that the most striking features of the present century is the process of science.We are lucky that there are many great invention have been born.Computer is one of the useful invention,but there are many teenagers addicted computers.Chatting,playing dota and many more is their priority instead of studying their lesson to be a successful one.We can see that this machine can influence in every aspect of their everyday life both for better and for worst.The advantage of science and technology are:
         1. Less work for human
                           -we don't need to work and work in order us to finish our job faster.We can use machine to help us in doing our work don't need our effort.
          2. Make life more enjoyable
                          -gadgets help people to forget their problems even in a few  minutes/hour.Modern technology now can help people to be more happier that  before,make life people enjoy their life to the fullest.
           3.Medicine easier to synthesize
                         -help the doctors to combine all ingredients needed effective medicine.Help in analyzing the right procedure in making medicine.
                4.Faster to do some jobs
                                   -machine help you to finish your job on time,and it can minimize your time in doing such job or task.You must depend the capability of that machine to do your work without any physical effort.

The disadvantage of Science and Technology

                                         Technology make people to be dependent,can't work without the the help of that machine.People become lazy,can't do in their own.They can't live without gadgets.Most people say that they can't live without computers,maybe that's true because even any school activities almost all student need computer and internet in making their reports and many more.But not that point that cant live without any gadgets,maybe others.Invention have also there disadvantage to us and even in our environment/society.Disadvantage follows:

           1.Environment is polluted and damage
                            -because of the technology and inventions that scientist invent in order  us to finish all our job on time and faster but still there are an effect that can  damage our mother Earth,they made our environment  more polluted because of
 the smoke that the vehicle produce and factories.
         



                                                                  
                                                                                                       2.More weapon created
              -easily in doing any kind of weapon with no license.Making weapon in an illegal way,they can easily make any  kind of weapon in just a minute in the help of such technology.

 3.People become lazy and don't work
                      -they depend on the technology,they usually use any invention to help or do their work.They become so dependent of all the gadgets that invented instead in using firewood in cooking but now we use electricity.
         4.Climate change
                         -the technology that being invented is the one reason for the climate change.Example is the refrigerator,it produce CFC that can make the ozone layer destruct or break the ozone layer that may result to climate changes.
