Dr. Aikin, I have a couple questions for you:

1) Was there anything surrounding the universe before the rapid expansion of space? Or is that question impossible to answer because space itself came from the big bang?

2) Could you explain in layman's terms what is inflation theory, its implications, and what kind of experiments were done to prove the inflation theory?

3) If all the energy and matter is conserved in the universe, then where did it all come from? I.e where did the initial singularity of the big bang come from?

Thanks a bunch for doing this AMA!

Dr. Gupta, what are your thoughts on consciousness? Is consciousness something that has emerged from physical neural networks in the brain or is it something abstract that has no physical root?

Dr. Greene, you mentioned in one of your documentaries that quantum entanglement may one day be designed to "transport" humans from one location to another. As a student of philosophy, I am disturbed by the implications of this from the standpoint of consciousness. If I were to recreate an exact physical replica of myself, what would happen to my consciousness? Can my consciousness be dissolved in one location and recreated using quantum information in another? How does quantum entanglement affect human consciousness?
