Dark energy what is it? Dark energy is a unknown energy said to take up 70 percent of the universe. The energy is a repulsive gravitational effect that is causing the universe to accelerate out-ward. No one knows exactly what dark energy is or where it comes from. Dark Energy is a new idea. Little is known about dark energy‚ yet it takes up a huge amount if the universe. Scientist were able to show the universe was expanding at an accelerated rate by measuring the red-shift of an object by comparing

The universe is made up of 93.5% of Hydrogen atoms‚ 6.3% of Helium and 0.2% of other elements. By looking at the spectrum of hot stars‚ upper solar atmosphere and solar wind‚ an abundance of Helium is determined. Only from the 1920s there were methods of calculating what elements were present in a gas by just observing its spectrum‚ due to the fact that different elements absorb and emit different wavelengths of light. (2) Gamow thought that nuclear fusions took place in the first minutes after

theory is perhaps the greatest discovery of all time. The Big Bang is a cosmological model that explains how the universe came to be and is based on known and well-tested laws of physics. However‚ the Big Bang theory does not explain why the universe was created. Three particular observations led scientists to believe in the standard hot Big Bang model: The expansion of the universe‚ the cosmic background of radiation and the abundance of light elements. Before these discoveries were made‚ the

English Renaissance drama grew out of the established Medieval tradition of the mystery and morality plays. These public spectacles focused on religious subjects and were generally enacted by either choristers and monks‚ or a town’s tradesmen (as later seen lovingly memorialized by Shakespeare’s ’mechanicals’ in A Midsummer Night’s Dream). At the end of the fifteenth century‚ a new type of play appeared. These short plays and revels were performed at noble households and at court‚ especially at

the age an origin of our universe? The issue to be discussed in the following paper is the 3 theories of how the universe started‚ the Doppler Effect‚ the age of the universe‚ the origin of the universe‚ red shift/blue shift and dark matter/dark energy. The Doppler Effect is a change in frequency and wave length of a wave. It’s caused by the change in distance between the thing creating the wave and whatever it’s measuring‚ seeing and hearing the wave. The universe was created over 14 billion

Measures of Astronomical Distances • Let’s view the Universe in terms of kilometres – The size of the observable universe is roughly 130‚000‚000‚000‚000‚000‚000‚000 km ! - Obviously measuring astronomical distances in km is inconvenient. - We need much BIGGER units of distance: • Some commonly used distance units: 1 ly (light year) = Distance traveled by light in 1 year = 9.46 trillion km 1 AU (astronomical unit) = average distance between the Sun & Earth = 150 million km A unit of distance‚

accept the gruesome nature of them. Everyday people do this with subjects that on the surface don’t seem to be disturbing‚ but when you delve into the facts behind them‚ are very unsettling. Roach directly compares “dissection and surgical instruction” to “meat-eating” in that they both “require a carefully maintained set of illusions and denial” (21). Meat-eating is inherently disturbing in that you are eating something that used to be alive. Personally‚ I was always disturbed with the idea that

scientific theories that attempt to explain how our universe began. The information contained below will attempt to outline the Big Bang theory and the Cosmological Argument. In 1929 an astronomer named Edwin Hubble discovered that the universe is expanding the same in all directions and from this conceived the Big Bang Theory (Craig 30). Everything in the universe is expanding outward. This implies that at some point in the past the entire known universe was contracted down to a single mathematical point
