Before the Big Bang

by Jack Le Moine

From the latest happenings in things historical. This article Ask Ethan: Could The Universe Be Infinite? was published 14 days ago in Forbes . The article’s author is Ethan Siegel.

Important facts cited in the article:

• Big Bang occurred 13.8 billion years ago.
• Observable Universe is 46 billion light years in all directions.
• Cosmic Microwave Background tells us that universe must extend at least 250 times more than that or (46 x 250 = 11,500) 11.5 trillion years in all directions.
• The universe existed before the Big Bang.
• The universe was expanding “inflating” before the Big Bang.
• This inflation caused the universe to reach some critical something which caused the Big Bang to happen.

This begs the question: if going forwards in time the universe expands then going backwards in time the universe contracts. What about the time when the pre Big Bang universe was so small it had the space of a sub-atomic point? It was so near zero to be zero?
