Planet Nine Existence? something is moving Finding something without knowing where to look is not easy, and if it is not even certain that the thing exists it becomes even morecomplicated.Know it well Michael Brown and Konstantin Batygin, two astronomers rather convinced that in the extreme periphery of our solar system is orbiting, never observed by anyone, a planet at least twice the size of Earth. For years the two diehards argue that the existence of this "ninth planet" would help to explain the strange similarities in the orbits of some objects that orbit in the most remote part of our solar system. So far these are only theories and models of celestial dynamics, discussed by an astronomical consensus divided so far equally between enthusiasm and skepticism. So that for a long time are alternating studies in favor and studies that instead want to demonstrate the inconsistency o...
When people say that Isaac Newton completely transformed the field of physics, they really aren't kidding.Another of Newton's famous contributions to physics was his understanding of gravity. When Newton was first starting, scientists' concept of gravity was pretty much nonexistent. I mean, they knew that when you dropped something, it fell to the ground, and from careful observation, they knew that planets and moons orbited in a particular way. What they didn't know was that those two concepts were connected. Of course, just like with motion, we now know that there's a lot more to gravity than what Newton could observe. Even so, regarding describing the effects of gravity on the scale of, say, our solar system, Newton's law of universal gravitation is incredibly useful. And it all started with an apple… Probably. Odds are, you've been told the story of Newton's apple at some point. The story goes that one day, he was sitting under an apple tree in his ...
