I am 30. I am right in the middle of my lifetime, more or less. And I wonder if half a life is enough to grasp Physics by the horns and learn all about nature? I totally love physics, the beauty and mystery that the universe truly is. I actually feel empty without reading or seeing something about physics everyday. I truly believe I have no other purpose in life but to keep staring at the sky in awe, all the time. What do you think? Is one lifetime too little to grasp the most beautiful mystery of our times, Universe and space?
