Document Summary
Our entire universe should be large but not in nite. Our visible horizon may only make up a small part of it, parts of our universe could still be in the false vacuum state. According to this picture, the sequence of events is: Tiny bit of false vacuum will eventually transform into our universe, it in ates faster than light. A tiny bit of the false vacuum will eventually transform into our universe. First, however, it in ates very rapidly (faster than light) An original seed (perhaps only millimeters in size) can rapidly in ate itself into a bubble billions or trillions of light years in size this way. Then, the false-vacuum energy in this bubble converts itself spontaneously into all the matter and light in our universe. Our visible universe (13 billion light years radius) is just a small part of our whole universe in a false vacuum.
