Gravitational wave

work and do studies on the big bang but mainly I am a professor the Astronomy and Physics Department at Harvard University. What type of work have you done on astronomy? Well, me and my team of radio astronomers had found the imprint of gravitational waves from the Big Bang.…

A tsunami is a seismic sea wave. Displacement of water forms a sequence of waves and this generally happens in an ocean or a large lake.Tsunamis are different because normal waves are caused by wind or tides, which is actually generated by the gravitational pull of the Moon and Sun. According to Source 1, the first recorded tsunami was back in 7000-6000 BCE and this was in Portugal but the primary cause is unknown. Since then there have been many tsunamis that have caused damage, two of the…

One can easily compare and contrast the idea of “faith” and the idea of “belief” by simply looking their definitions up in a dictionary. I will explain the two concepts, however, because some people – for whatever reason – question the importance of dictionaries and their place in an intellectual environment. First and foremost, all faiths qualify as beliefs, but not all beliefs are faith. If this is confusing, it follows the same logic behind the following statement: “all boys are people, but…

structure growth in the Universe as a function of redshift. This map, spanning 3/4 of the lifetime of the Universe will complement the single snapshot at z ≈1100 made by WMAP and Planck. By combining the use of Redshift measurements (4.1), Weak gravitational lensing (4.2) and Baryonic Acoustic Oscillations (4.3), both Dark Energy (DE) and Dark Matter(DM) will be investigated in the following tasks: 1. Construct a three-dimensional Dark Matter map to a depth of z=2. See Figure 2. 2. Measure…

and the same remains true even at the massive scales of the Universe. These clouds of gas and dust can be billions of miles across (Chinn, 2010b), and as such, require significant events to occur to displace them. The movements of galaxies and shock waves from supernova explosions are examples of events that can cause the gas and dust clouds to be…

The following paper is on each of four subjects: black holes, dark matter, dark energy, and the multiverse theory. The first subject is black holes, which are regions of space having a gravitational field so intense that no matter or radiation can escape. Their existence is greatly debated over, and it still has not been determined whether they exist. The second subject is dark matter. Dark matter is a placeholder that cannot be seen. It accounts for 27% of the matter in the universe, but like…

nuclear fusion it didn’t need to produce ("ABOUT SUPERNOVAE."). The second case occurs when the star can no longer begin nuclear fusion and its mass begins to melt into its core where it eventually gets so heavy the star can no longer support its gravitational field and explodes under its own weight ("What Is a Supernova?"). According to NASA Science, as long as the star’s core is three time the mass of the star itself it will start becoming a black hole by first creating an event…

holes, to which she replied, “It is all about two things: gravity and internal pressure within the star.” I was aware of the gravity factor but had no idea about internal pressure. She further explained that these two things oppose each other- the gravitational force will try to contract the star and the internal pressure will act outwards. When both of these are balanced out, the star will maintain its size and will neither expand nor collapse. However, if a star runs out of fuel, and therefore…

the naked eye, a radio telescope is used that detects the radiation. Electromagnetic energy describes the different kinds of energies released into space by stars such as the Sun. They include: Radio waves, TV waves, Radar waves, Infrared radiation (heat), Light, Ultraviolet light, X-rays, Short waves, Microwaves, Gamma rays. However, all kinds of electromagnetic radiation, like harmful gamma rays, are released from the Sun, our atmosphere stops some kinds from getting to us. The ozone layer is…

the Development of the Four Fundamental Forces Nature has a total of four fundamental forces. The forces include gravitational, electromagnetic, strong nuclear and weak nuclear force. Gravitational force is the force of attraction between all masses. Every object in this universe is pulling upon other objects. Many scientists came up with logics to explain the science behind gravitational forces. The first one to try was Aristotle in around 330 BC. Aristotle believed Earth and the heavens were…
