“It’s okay, Honey, we have about five billion years.”

“Is five billion years a long time?”

“Yes.”

“How long?”

“Well, if you started counting and counted every second for the rest of your life, you might never reach five billion and we’re talking years, not seconds.” Then adding, “Years are much longer than seconds.”

Never before has anything so far away come even close to naked-eye visibility. The explosion was so far away that it took its light 7,500,000,000 (7.5 billion) years to reach Earth! In fact, the explosion took place so long ago that Earth had not yet come into existence. Source: NASA website
