The white hole -  A theory concepts Baperookamo, CC BY-SA 4.0, via Wikimedia Commons From Einstein's theory in mathematics, in the theory of general relativity, it is a rare item, a white hole. The white hole, the twins, the black hole was first invented in the 18th century, the geologist John Mitchell. In those days, the black hole, which is not considered to be a real Einstein-so, it was believed that they did not exist. At the same time, Einstein's general theory of relativity predicts the path of a concept called a white hole. More specifically, it is the mathematics of the general theory of relativity says that the white hole is possible. If you have to take the math of a black hole, and literally, turn on it, and you will get a white hole. Or even a white hole is a black hole for time. Thus, the black hole will not allow a non-issue for the end of a question of crossing the event horizon, an imaginary boundary around a black hole, and there is no matter, it can end whenev...

Birth History of Our Solar System Welcome to my blog, "Astronomy knowledge point".  As we look around our own solar system, we need to keep in mind some of the features that we'd like to forget.  To begin with, it all revolves around the Sun in the same direction. That is, if you look at the surface area of the solar system, for example, from the above, all of the world around us and would be rotating counter-clockwise around the Sun. However, there are a few exceptions to these rules are simple, and sometimes it seems that, on a whim, that it is moving clockwise, when viewed from above. Otherwise, yeah, all of which are rotating in the same direction.  Another thing to keep in mind is that if you look at the planets in our solar system, " says the orbit of Neptune, you'll find that all those planets revolving around the Sun in approximately the same plane, that is, in fact, what we call the ecliptic. However, the Neptune's, as you can see, it has an abundanc...
