Dark Matter and Dark Energy Dark Matter and Dark Energy are important. They can help us know how the universe began. These two are the mysteries of the universe; they compose about 90% of the universe. They are mysteries because we believe that they exist but we can’t see them or detect them. People question whether they manifest to be the same thing. Astronomers know very little about their constitution so they cannot assume they are related. Dark Energy is a mysterious force that drives the
long run opportunity for growth and profitability. They have high relative market share and high Growth rate. PULSAR 150 and 180cc are the fastest growing and have potential to gain substantial profit in the market. QUESTION MARKs: they are also called as wild cats. Usually, they are new products with potential for success but there cash needs are high and cash generation is low. PULSAR 200 & 220 cc, DISCOVER 135cc, XCD 125cc -there aim has been to improve the organization reputation However, their
team of astronomers announced then retracted the alleged discovery of an extrasolar planet around a pulsar star (Lyne and Bailes 1992). Planets are extremely hard to detect as they are a very faint light source and the light from its parent star is much brighter and essentially blocks out light from a planet (Winters 1996). It was not until 1992 when the first exoplanets were confirmed orbiting a pulsar star (Wolszczan and Frail 1992). Finally in 1995, the first exoplanet orbiting a main sequence star
Chapter 1 Relativity and Gravitation 1.1 Introduction Einstein’s General Relativity (GR) is the standard theory of modern gravitation. It forms one of the key pillars of theoretical physics and has been enormously successful in its ability to explain real physical phenomena. The theory emerged out of an attempt to incorporate Newtonian gravity into Special Relativity (SR) and shortly after its inception in 1916, was successfully tested in the solar system where it instantly confirmed the predictions
When driving their cars in cities other than the one that they live in, how can people find out the way to their destinies? Perhaps they will use maps and compasses, or they can ask the pedestrians for instructions. Such ways will definitely work, yet, nowadays, a new way of navigating, the global positioning system, has arose, gradually gaining its popularity among car drivers and travelers. Behind the booming of using global positioning system stands the General Relativity, a theory that enhanced
