the universe

What tells us to talk about the size of the universe of science clearly shows that the universe is widespread and massive world, but nevertheless may be a small point of trillion bucket, as described by the US International newspaper "The Epoch Times" site, which dealt with this subject. If we look at the other side of the question: "How much larger universe?" It is "How are young people in it?", It would be amazing to imagine the scope of the space around us, which scientists estimated that a piece needs to be 93 billion light-years away. How the size of the star? The diameter of our sun is about a hundred times Earth's diameter. The biggest star of a known size "in Wi-Kanis Majoris" (VY Canis Majoris) about two thousand twice the size of the sun, drip equivalent to about 2.89 billion kilometers of the sun compared to 1.384 million kilometers in diameter. To put it in the perception of the earliest human measure, if the passenger jet traveling at a rate of natural speed of about 885 km / h, it will need to be about 1,100 years to revolve around the star once. How many galaxies in the known universe? Scientists counted more than one hundred thousand galaxy to make a three-dimensional map of the universe is known, according to astronomer Karen Masters in "Ask the astronomer" at the University of Cornell, but the total number of galaxies is unknown, although some appreciated by about two hundred billion galaxies. To understand how big a billion used software engineer at Microsoft, Google and Apple companies, Gayle McDowell to Wakeman, appreciation of the existence of a hundred billion galaxies in the known universe to make comparisons. I wrote McDowell says, "If you have dollars, you are closer to the net, Bill Gates fortune (estimated fifty billion dollars) from the galaxy to the total number of galaxies," or "if subjected to a diet and lost ten pounds (4.5 kilograms), the amount of weight they lost impact on the total weight of the world's population (the total weight of each person on the earth's surface) more than the impact of our galaxy on the total number of galaxies in the universe. The Milky Way galaxy Ahadjm- -the medium needs to cut about a hundred thousand light-years away, so the spacecraft will need to be two hundred thousand years to travel from the galaxy to the other party and its tip back if they are going the speed of light. How many planets in the galaxy? Assistant professor says in astronomy, planets, John Johnson, of the California Institute of Technology that there are at least a hundred billion planet in the galaxy, and our galaxy is intended only here, can imagine the total number of planets in the galaxy in the universe?
