Astronomy 10 Chapter 11 1. Both used to be normal stars but the white dwarf ran out of hydrogen, they are both subjected to gravitational theories. A Neutron star is a fluid of neutrons, as hot at its surface as the inside of the sun and has a greater magnetic field. 3. Because its density is so high, neutrons spin in the same way that electrons do so must obey the Pauli Exclusion Principle.
At the very start, the entire universe was about a size of an atom. It was termed by Georges Lemaitre as the “primordial atom”. As one of the pioneers of in the make of the big bang theory, Georges Lemaitre proposed this new theory. At that time, this theory has explained many difficulties that were met by the theories proposed previously. For example, a theory states that the universe is infinitely large with an infinitely amount of stars was met by the Olber’s paradox.
More than a century later, Einstein, came up with the theory of relativity. It states that nothing can travel faster than the speed of light, therefore, no matter can escape it. (O.N.L. 47-56) Karl Schwarzschild, in 1917 used Einstein theory to calculate that if a star of a curtain mass was to shrink pasted the critical point it would become a Black Hole. The theory is named in his honor, the Schwarzschild radius.
Due to today’s advanced technology, “the most powerful modern telescopes can detect objects billions of light-years from Earth”. Therefore, it proves that the early universe had been more crowded and different from the present universe. Although this theory has such evidence behind it, one major doubt arises: in a world ruled by the second law of thermodynamics, how is it possible to generate such complexity – as the tendency of the universe is to go from order to
The energy released is in the form of increased kinetic energy of the product particles and any radiation emitted. The energy released in a nuclear fission is very much larger compared to the energy released in a chemical reaction. Spontaneous natural nuclear fission reactions very rarely occur. Nuclear fission reactions are normally initiated by bombarding the nucleus with slow neutrons or thermal neutrons of low energy of about 10-2 eV. Nuclear fussion: Nuclear fusion is the process in which two light nuclei combine to form a heavier nucleus.

The writers of Genesis 1-2 wrote it in a way that presents the Earth’s creation as a factual account of God creating the heavens and the Earth. This account directly conflicts with the prevailing scientific creation theory, the Big Bang Theory. It explains that the universe was once in an extremely hot and dense state, which approximately 13.7 billion years ago expanded rapidly. This rapid expansion allowed the universe to cool over time, resulting in its present continuously expanding state. When these two creation
This new theory of energy transformed physics and opened the way for Albert Einstein's theory of relativity. In contrast to Einstein's Theory of Relativity, quantum theory deals with the tiniest things of which we know of, the particles that atoms are made of, which are called "subatomic" particles. In contrast to Relativity, quantum theory was the work of more than one person. The Theory of Relativity was proposed by the Jewish physicist Albert Einstein, in the early part of the 20th century, and is one of the most important scientific advances of our time. Although the thought of relativity was not introduced by Einstein, his major contribution to it was the recognition that the speed of light in a vacuum is a constant and an absolute physical boundary for motion.
Although the issue did not start to gain national attention until the early 2000s, scientists have been studying atmospheric gases and the effect that human consumption of fossil fuels has on the atmosphere and climate since the early nineteenth century (Rich). The overwhelming consensus among scientists today is that the climate is changing drastically and humans are causing it through specific, preventable actions (Rich). Global warming is caused by an increase in greenhouse gases, which, under normal conditions, it (the greenhouse effect) is what makes life sustainable by keeping the earth within a constant range of temperatures (Gore). About 30 percent of the light and the heat of the sun is reflected back into space, either by clouds, or by the earth’s surface (especially ice, which is particularly reflective.) About 20 percent of the light and heat from the sun is
There’s a lot more to big history than just substances, there is also our story and how we came to be and we call these modern scientific origin stories. We came from elements, which came from dying stars, which came from helium and hydrogen fusing together due to gravity, which came from the big bang; so technically, we came from the big bang. From this, we can tell that the big bang is the origin of our universe and that’s where all matter started. It is also the beginning of our modern scientific origin story since it’s where it all started and came from. One of the most important things about the big
