An Exceptionally Simple Personal FAQ
Garrett Lisi

Over the past month I have been asked many questions about my personal history and opinions on life, the universe, and everything. I have also received many emails of encouragement from the general public, which have been wonderful and completely overwhelming. This blog comment thread will collect my responses to questions about my history and opinions, in chronological order. If you would like to offer your own opinions, encouragement, or discouragement, feel free. There is a separate, Exceptionally Simple FAQ that has descriptions of E8 Theory suitable for the interested reader.

To my mind, the creation of universe can't be anything else that this geometrical form or structure. I imagine that the laws of our universe are included in this structure and revealed by it, and I think this beautiful structure was born from the nil to our reality in this exceptional instant we called the Big Bang.

But I have a question for you : do you think that the laws included in this structure could exist before the Big Bang ?
