Protoplanet Theory, The Solar Nebula

The natural sciences develop, people take more interest in the surrounding world, and the role of religion becomes smaller. The heliocentric model of the Solar system replaces the geocentric model. The Great Voyages are changing the worldview and creating the bases for the colonialism.

These protoplanetary disks span about 0.14 light years and are probably similarto the Solar Nebula.

As a result of high boiling points, only materials such as metal and rock could exist as a solid near the Sun. Hence, the planets of Mercury, Venus, Earth, and Mars reside closest to the Sun. In contrast, Jupiter, Saturn, Uranus, and Neptune form beyond the , a location cool enough for frozen, volatile compounds to remain solid. In a nutshell, this is the Nebular Hypothesis.7

Clair Cameron Patterson was responsible for determining the current estimated age of the Solar System. For hundreds of years, the age of the solar system was always being debated and changed. These dates were all incorrect but they stood the test of time until Clair Cameron Patterson showed up on the scene.

Thoeries of the Origin of Solar System 1

The disk of the Milky Way is born. The first third generation stars (Population I) form. These stars can have Earth-like planets around them. It is still 4 billion years to the formation of the Solar System.

Solar system origin: Nebular hypothesis - CMI Mobile

The age of the Solar System has been studied throughout the world for hundreds of years and is a question that will likely never have an answer with complete certainty. Existence as we know it, did not develop from a timeline. Mankind has had an intrinsic motivation to know how we came to be, where we came from, and why we are here existing. Attempts have been made throughout the course of history into how the solar system formed, specifically how long formation would have occurred. Without the use of something convenient such as time travel, academics were restricted to the information available to them. This article will touch on some of the more prevalent theories pertaining to the age of the solar system, and divulge into their utility over the course of human history. Solar System theories will be divided pertaining to age and formation into two categories, early attempts and recent theories. The early attempts such as those from biblical eras, will briefly discuss theories that have been disproven. While more recent theories developed in the latter portion of human existence, will reflect those that are still relevant today. Five main theories presented are; Vortex, Nebular, Patterson, Apollo Missions, and Late Heavy Bombardment. Our team chose to focus on those five because, they each contribute aspects into the general question of the age of the solar system – as well as providing insight into the ever large daunting task of establishing a definitive age with limited resources. Through these theoretical advances, theories are able to be evaluated and reconsidered, allowing progressive understanding in regards to the age of the Solar System.

How Was the Solar System Formed? – The Nebular Hypothesis

The Earth is bombarded by meteorites. The orbits of Jupiter and Saturn synchronize, causing Uranus and Neptune to change orbits. The inner Solar System is swarming with comets. Massive numbers of objects hit the Earth demolishing most of its surface. If life had allready started, it was now destroyed. The large craters on the Moon are formed.

Research Essay “On the Origin of the Solar System”

Currently there is no single ’origin of life’ theory, but several contradictory hypotheses. We do not even know exactly when life started. Possible outline is likely to be following: First prebiotic chemistry produces building blocks of life and then, at the presence of suitable energy source, these monomers build up self-replicating RNA-chains and other biological macromolecules. Finally first living cells are formed from the biomolecules. Still, different hypothesis do not agree of the order or in what conditions these steps happened and structures developed.
