The Big Bang... What is it??

Image
Astronomers combine mathematical models with observations to develop workable theories of how the Universe came to be. The mathematical underpinnings of the Big Bang theory include Albert Einstein's general theory of relativity along with standard theories of fundamental particles. Today NASA spacecraft such as the Hubble Space Telescope and the Spitzer Space Telescope continue measuring the expansion of the Universe. One of the goals has long been to decide whether the Universe will expand forever, or whether it will someday stop, turn around, and collapse in a "Big Crunch?" Background Radiation According to the theories of physics, if we were to look at the Universe one second after the Big Bang, what we would see is a 10-billion degree sea of neutrons, protons, electrons, anti-electrons (positrons), photons, and neutrinos. Then, as time went on, we would see the Universe cool, the neutrons either decaying into protons and electrons or combining with protons to ma...

Acoustic waves reveal that some stars spin faster at the equator than at the poles

Spinning around: the green arrows represent rotation speed in the stellar convection zone. Differential rotation is inferred from the oscillatory motions of the star seen as orange/blue shades on the right side of the figure. (Courtesy: MPI for Solar System Research/MarkGarlick.com) An international team of astronomers has observed latitude-varying rotation in the outer layers of 13 Sun-like stars and shown in great detail that the Sun is not alone in displaying this curious behaviour.  Othman Benomar  at New York University, Abu Dhabi and his colleagues made the discovery by measuring distinctive patterns of acoustic oscillations in the stars. Their discovery could help to advance our understanding of the elusive mechanisms which play out deep within the Sun and other stars. By observing the movements of sunspots across the Sun’s surface, astronomers have known for some time that our host star’s equator rotates 30% faster than its poles – a phenomenon known as “differenti...

Why do Japanese Fear Number 4 ?

Image
  Tetraphobia    is a   fear   of the number   4 . It is a   superstition   found most often in   East Asian  areas like   China ,   Japan ,   Korea , and   Taiwan . An elevator in Shanghai – floor numbers 4, 13 and 14 are missing The Chinese word for  four  (四, pinyin: sì, jyutping: sei), sounds very similar to the word for  death  (死, pinyin: sǐ, jyutping: sei). Chinese people take care not use the number 4 during important holidays, or if someone in the family is sick. Numbers such as 14, 24, and so on, are not used because they also have the number 4 in them. Buildings sometimes do not have floors with these numbers, apartments and hotels do not have rooms with number 4, 14, 24 and so on. Table number 4, 14, 24, may be often left out in wedding dinners or other social activities in ...
