Nuclear energy must be a consideration for the future with the rapidly depleting supply of fossil fuels. This type of energy can be created through nuclear fission and nuclear fusion. Nuclear fission is the splitting of a heavy atom into two or more parts, releasing huge amounts of energy. The release of energy can be controlled and captured for generating electricity. Nuclear fusion involves bombarding hydrogen atoms together to form helium. In the long run, nuclear fusion has greater potential than fission.

The discovery of fission occurred during a time of great turmoil. Two German physicists then later verified by two Jewish refugee physicists discovered it. Italian Physicists Enrico Fermi later discovered the unique quality of fission that was induced by neutrons but also produced neutrons. This created the idea of a self-sustaining chain reaction, and the large amount of energy found within a nucleus was now accessible at a large scale (Nuclear weapons section, para 1).
As of now, 80% of global energy is provided by fossil fuels. Wind and solar energy sources are unlikely to completely replace fossil fuels in the coming decades due to infrastructure problems. A drop in global energy provided by oil starting sometime between 2012 and 2014 (Chris) is also expected. As a result of these circumstances more research must be done in other forms of energy generation in order to keep with energy demand as countries industrialize and populations grow. Despite claims that nuclear fusion will not be practically realized, research into nuclear fusion should be increased as it is not harmful to the environment, has nearly limitless fuel, and is inherently safe. Fusion power produces no greenhouse gasses and no long-lived radioactive products, making it a very clean energy source. According to the article “Safety and Environment,” “Fusion power does not produce any greenhouse gasses (GHGs) or other atmospheric pollutants during operation.” It has become an increasing desire for things, such as cars and companies, to become environmentally friendly or “green.” The fact that fusion power would generate no greenhouse gasses inherently is a big plus. Furthermore, according to the same article, “SEAFP concluded that fusion has very good inherent safety qualities, among which... no production of long-lived, highly radiotoxic products.” The radiotoxic products produced by nuclear fission pose a large environmental problem due to storage required. Fusion is much more environmentally friendly than fission because it lacks these products.

A star begins as nothing more than a very light distribution of interstellar gases and dust particles over a distance of a few dozen lightyears. Although there is extremely low pressure existing between stars, this distribution of gas exists instead of a true vacuum. If the density of gas becomes larger than .1 particles per cubic centimeter, the interstellar gas grows unstable. Any small deviation in density, and because it is impossible to have a perfectly even distribution in these clouds this is something that will naturally occur, and the area begins to contract. This happens because between about .1 and 1 particles per cubic centimeter, pressure gains an inverse relationship with density. This causes internal pressure to decrease with increasing density, which because of the higher external pressure, causes the density to continue to increase. This causes the gas in the interstellar medium to spontaneously collect into denser clouds. The denser clouds will contain molecular hydrogen (H2) and interstellar dust particles including carbon compounds, silicates, and small impure ice crystals. Also, within these clouds, there are 2 types of zones. There are H I zones, which contain neutral hydrogen and often have a temperature around 100 Kelvin (K), and there are H II zones, which contain ionized hydrogen and have a temperature around 10,000 K. The ionized hydrogen absorbs ultraviolet light from it’s environment and retransmits it as visible and infrared light. These clouds, visible to the human eye, have been named nebulae. The density in these nebulae is usually about 10 atoms per cubic centimeter. In brighter nebulae, there exists densities of up to several thousand atoms per cubic centimete...

Our sun is the central pivot point to which or entire planet and solar system is built around. With out it all life on our planet would cease to exist. Within this paper we will explore how our Sun and solar system formed and came to resemble what we see today.
Supernovas are extremely powerful explosions of radiation. A supernova can give off as much energy as a Sun can within its whole life. A star will release most of its material when it undergoes this type of explosion. The explosion of a supernova can also help in creating new stars.

I think that right now, fission is the only way that we can get more
The Industrial Revolution sparked a need for large sources of energy. Human and animal labor could not provide the power necessary to power industrial machinery, railroads, and ships. The steam engine and later the internal combustion engine provided the bulk of the energy required by the industrial age. Today most nations are still heavily reliant on energy that comes from combustion. Usually coal, petrolium, and natural gas are used. Some hydroelectric, wind power, and nuclear fission sources are used, but in the US they accounted for less than 20% of the total energy consumption in 1997 (1). Many experts are worried that natural resources such as coal and petrolium are being depleted faster than they are being replenished, which could result in an energy crisis. Nuclear fission produces highly radioactive waste that is expensive to dispose of properly. Nuclear fusion reactors would produce much less radioactive waste and would be more efficient than nuclear fission, but to date there have been no nuclear fusion reactors that have generated usable energy output. Why is fusion power, which could be very beneficial, so hard to come by?
