Will the Universe Ever End? Does Cosmic Fine-Tuning Demand Explanation? Details Share I look up and I look down and I chill with awe. I look up to the universe and envision hundreds of billions of galaxies. I look down to the atom and imagine minuscule, infinitesimal particles and forces. This is reality.
