Enlightening Revelations

There's one thing that can move even faster than light: the expansion of the universe itself. The observable universe is incredibly awesome, even if it is a very small fragment of a potentially infinite entity. The light from stars that died long before our planet was born continue to reach Earth. Photons from the CMB (cosmic microwave background) may be around 13 billion years old. but they are from a region that is now 46 billion light years from Earth- or 440 "yottameters", the largest unit in the metric system- assuming that the cosmic inflation rate is constant. If intelligent life still exists in our solar system in a billion years, those observers might discover "new" galaxies and stars when their light finally arrives at Earth. It is possible to observe objects that are travelling away from us at "superluminal" velocities that are quicker than light speed. These objects aren't moving through space faster than light themselves, which is impossible according to known physics. Rather, space-time itself is outpacing light speed. Beyond the observable universe, you won't just find more planets an d stars and other forms of material....you will eventually find every possible thing. The Milky Way does not sit still, but is constantly rotating. As such, the arms are moving through space and the Sun and the solar system travel with them. The solar system travels at an average speed of 515,000 mph. There could be as many as 40 billion Earth-sized planets orbiting in the habitable zones of Sun-like stars and red dwarf stars within the Milky Way galaxy. The Universe was born during a period of inflation that began about 13.8 billion years ago. Like a rapidly expanding balloon, it swelled from a size smaller than electron to nearly its current size within a tiny fraction of a second. Fifty trillion neutrinos from the Sun pass through your body every second.
