Origin of the Earth

the planets fall around the Sun. Each of these objects balances the Sun 's force of gravity

After its core hydrogen is depleted, a red main sequence star will go supernova after its red giant phase.

4. What is meant by the phase “looking out in the universe is looking back in time?”

Although all nine planets are a huge part of the solar system there's a lot more to the solar system than the nine planets. According to scientist the Solar System started out as an enormous cloud of gas and dust. Scientist believe that the cloud of dust and gas began to collapse under the weight of its own gravity and it did. The matter that was kept within itself began moving in a giant circle and at the center of the spinning cloud a tiny star began to form. The star eventually grew larger and collected more dust and gas that collapsed into it. Farther from the center of the mass that was being formed there was many smaller clumps of dust and gas that were also collapsing. The large cloud in the center eventually became the sun while the smaller clumps formed the planets, moons, comets and,

If the planets were indeed orbiting the earth, they would have to move in very complex patterns. Copernicus said a simple circular orbit would account for the planets' movements if they were orbiting the sun. This became known as the Copernican Theory. Copernicus was one of the first to come up with a new idea to support his observations instead of making his research fit his

As this slow contraction continues, the core temperature, density, and pressure of the star continues to increase. As the star shrinks it becomes so dense that it starts to compress helium. This results in the star to swell due to the hot core and leaving a relatively cool surface. Eventually the outer layers of the star expand outwards, increasing the size of the star. As the layers continue to expand, the surface temperature continues to cool, forming a relatively large star called a red giant.

The Ptolemaic view of the motions of the stars was earth centric, or geocentric. Ptolemy believed that all the planets revolved around the earth, the earth was the center of the universe. Copernicus on the other hand held the belief that the universe revolved around the sun, or that the universe was heliocentric. Copernicus also only considered there to only be six planets, as he didn’t count the moon like Ptolemy. Kepler held similar beliefs t Copernicus, and believed that the reason why a god-created universe only had six planets instead of seven was based on Plato’s idea of the five Platonic Solids. That just like there are only five forms of matter and five platonic solids, the universe must have been intelligently created in a similar

It should be easy to say that the Earth was created by a higher power. For a Christian this higher power is God. The Bible gives us the six day creation of the heavens and the Earth and all that dwell upon it. For anyone else, the higher power is some unknown power that science is still trying to figure out. There are a lot of theories in science about how the Earth was created. One of these theories is the big bang theory. The essay will compare the two theories and show how different they are.

1. What is the difference between a hypothesis and a theory? (Pages 2 – 3)

A logical argument for God’s existence or nonexistence is the cosmological argument. William Craig says in his book that there are three statements that give the cosmological argument form. Craig concluded that whatever begins to exist has a cause. The Universe began to exist therefore the Universe had a cause. What that cause was, is widely challenged. The argument against the existence of God includes the Big Bang Theory. The Big Bang Model is a broadly accepted theory for the beginning and evolution of our universe. According to NASA, it claims that twelve to fourteen billion years ago, the part of the universe that can be seen today was only a few millimeters across. It has since expanded from this hot dense state into the vast and much cooler cosmos that is inhabited. Remnants of this hot dense matter as the now very cold cosmic microwave background radiation can be seen which still pervades the universe and is visible to microwave detectors as a uniform glow across the entire sky. Those who say that God does not exist use this as their argument to explain how the universe was created. Those who support this theory say that the universe resulted from a big bang and everything that is in existence came from this phenomenon. In talking about the Big Bang Theory, Jeffrey Keen said, “In general, science accepts that both the structure of the universe and the laws of physics were created simultaneously at the beginning of the Big Bang, and have since remained constant

The Big Bang Theory is the name given to mark the event of the birth of the universe and is the scientific theory about what happen in the earliest moments of the universe, and how the universe was an extremely hot and dense of subatomic particles and radiation. The big bang let insights about how old the universe is and the universe is 14 billion years old and it has changed throughout its time.

     There are two different beliefs of how everything came to be. One is creation. Creationalists believe in what the Bible says which is that God created everything. Another is evolution. Evolutionalists believe that there was a "big bang" which brought forth everything. In this paper, I'm going to give the arguments that prove evolution wrong.

In the nebular hypothesis, the solar system started out as a cloud. The cloud of gas cooled and shrank into a sphere. The law of conservation of angular momentum caused the sphere to spin faster. Centrifugal forces caused some of the matter to fly off of the sun. This matter formed a ring around the sun. The matter that was originally a part of the sun cooled and condensed into the planets. One problem with the nebular hypothesis is that an unreasonably large amount of gravitational pull would be needed to condense the rings of matter into planets. Also, the Sun, although containing most of the mass in the solar system, has only a small fraction of the angular momentum.

After several hundreds of millions of years of slow, gradual migration, Jupiter and Saturn, the two inmost giant planets, crossed their mutual 1:2 mean-motion resonance of orbital motion. This resonance increased their orbital eccentricities to such an extent, that it destabilized the entire planetary system. The arrangement of the giant planets altered quickly and very radically. Jupiter shifted Saturn out towards its present position, and this relocation caused mutual gravitational encounters between Saturn and the two ice giants, which subsequently propelled the planets Neptune and Uranus onto much more eccentric orbits. These ice giants then ploughed into the planetesimal disk, scattering tens of thousands of planetesimals from their formerly stable orbits in the outer Solar System. This disruption almost entirely scatters the primordial disk, removing almost 99% of its mass, a scenario which explains the modern-day absence of a dense trans-Neptunian population. Some of the planetesimals were thrown into the inner Solar System, producing a sudden influx of impacts on the terrestrial planets: yes! It is the Late Heavy

Main sequence stars like our own sun enduring in a state of nuclear fusion during which they will produce energy for billions of years by replacing hydrogen to helium. Stars change over billions of years. When their main sequence phase ends they pass through other states of existence according to their size and other characteristics. The larger a star's mass, the shorter its lifespan is. As stars move toward the end of their lives, much of their hydrogen will be converted to helium. Helium sinks to the star's core and raises the star's temperature—causing its outer shell to expand. These large, puffy stars are known as Red Giants. The red giant phase is actually a prelude to a star shedding its outer layers and becoming a small, dense body called a White Dwarf. White dwarfs cool down for billions and billions of years, until they finally go dark and produce no energy at all. Once this happens, scientists have yet to observe, such stars become known as Black Dwarfs. A few stars avoid this evolutionary path and instead go out with a bang, exploding as Supernovae. These violent explosions leave behind a small core that will then turn into something called a Neutron Star or even, if the remainder is large enough, it is then turned into something called a Black Hole.
