The Theory Of Dark Flow Essay

959 words - 4 pages

Imagine a mystical, invisible influential power, pulling our galaxy far, far away from where it should be. Imagine the milky way being pulled millions and millions of km away. The planets pulled far apart from each other. This would ensure a certain demise of current life forms, forever changing our world. This is the effect of dark flow. Fortunately this appears to be occurring in distant galaxies, however observations have concluding our galaxy is too being pulled away in a specific direction. This highlights the essentiality of more research being conducted upon this unexplained force.

Good Morning class, today my chosen topic is the term dark flow.

Now dark flow is a basically a term used to explain astronomical observations, that appear to show certain areas of space accelerating and expanding at a rate that is abnormal in comparison to surrounding regions and the expectation of the acceleration rate that is formed from the basis of laws, rules and models.

However,these observations have profound controversy in the scientific arena, many scientists refuting the evidence.

Today we shall look upon both arguments for and against dark flow.

Firstly we shall look upon the formula that shows how acceleration is 'supposed' to occur.

Regarding the laws of physics, relative gravity should be able to explain how the galaxies are moving. Relative gravity involves the force of gravitational energy as a universal law. As Alok Jha states, "It encapsulates the idea that all the particles of matter in the universe attract each other through the force of gravity" (Jha, 2013). In other words, gravitational attraction extends to planets attracting each other, not having the ability to move without an outwards force being applied. Therefore, for galaxies to be moving at the high velocity they appear to be moving at, it is impossible to explain it away with universal gravity. The theory of universal gravity shows this, that it is represented as the force of gravity between the two objects (in this case the galaxy clusters) and thus being proportional to the mass of object one (galaxy one) and the mass of object two (galaxy two), divided by the distance from each other’s centres squared. Therefore this formula states that the two galaxy clusters force of gravity between them should remain proportional when divided their combined masses and squaring the distance between the galaxy clusters from their centre point. When analysing the data results, this is shown to be inaccurate, the gravitational force not remaining inversely proportional, instead appearing as too little for the force that is being observably exuded. Therefore, scientists have decided upon alternate explanations for where the additional force is coming from, causing the galaxy clusters accelerated movement. (Newtons Law of Universal Gravity, 2001).

So far there are two separate theories explaining the data showing ‘dark flow’. The first analysis of this data was conducted in...
