Mechanism of Black Holes - Research Paper Example the term â€Å"black hole† refers to a region of space-time from which the gravitational pull is so strong that it does not allow anything, including light, to escape (Begelman, 2003), which implies that black holes cannot be observed. This essay will explore the concept of black holes, that is, all that is currently known about this phenomenon, how they are formed, and what can be learnt from them; similarly, this essay will also highlight how black holes are detected and how they are made. The appearance of an event horizon, the boundary in space-time through which matter and light are attracted inwards towards the mass of the black hole becoming trapped permanently, is the most distinguishable feature of a black hole. As noted earlier, not even light can escape from a black hole since anything that draws nearer and crosses the event horizon boundary is trapped due to the strong gravitational pull that defines black holes (Kormendy, Bender & Cornell, 2011); an event horizon is thus called since if an event occurs within the boundary, this information is never known to an outside observer. Einstein’s theory of relativity argues that the presence of mass distorts spacetime thereby causing the paths taken by particles to bend towards the mass and given that this deformation is so strong at the event horizon, no paths can lead away from the black hole because all matter is trapped inside, including light (Hooft, 2009). Precisely, an object falling into a black hole appears to slow down as it draws nearer to the event horizon but never really reaches it, due to the gravitational time dilation effect (Nrumiano, n.d). Similarly, an outside observer will experience all processes on an object nearing the event horizon as slowed down, and the emitted light will appear dimmer and redder due to the gravitational redshift effect; as soon as the falling object reaches the event horizon, it becomes so dim that it can never be seen. Black holes often form at the ends of the

Entrepreneurship Acunu Ltd - Assignment Example Using the above approach the objectives of Acunu Ltd could be described as follows: a) the firm emphasizes the use of information as a strategic tool for supporting daily operations of firms in all industries; in fact it is the rapid, even on real-time, process of information/ data on which Acunu Ltd focuses in order to secure its competitiveness in the UK market; b) Acunu Ltd has developed a unique software programme, the Acunu Analytics, which is able to offer data analysis support of high quality using advanced features, as described in the organizational website; the promotion of this programme, as the basis of its services, is among the key objectives of Acunu Ltd; c) Acunu Analytics, the key programme of Acunu Ltd, addresses businesses in all sectors; there are no specific criteria set by the firm in regard to the provision of its services; this means that the above programme can be applied in a quite wide business area; the approach used by Acunu Analytics for communicating wi th its potential customers can be characterized as generalist approach (Kozami 2002), not being limited on the basis of specific terms. A successful mission statement needs to be broad so that it cannot easily become ‘outdated if the business changes its objectives/ priorities’ (Lamb et al. 2008, p.35). Moreover, such mission statement would focus ‘on the market that the firm is interested to attract’ (Lamb et al. 2008, p.35); a description only of the goods/ services of a business would not constitute an effective mission statement. In Acunu Ltd there is no a clear description of the mission statement; after reviewing the organizational website the following mission statement would result: the firm aims to help businesses to secure their growth by using their data more wisely. As a concept, business vision is usually related to the identification of ‘a unique path for the business’ (Wenger 2007, p.19), i.e. a path that would make the business to secure its competitiveness.  Ã‚
