Very interesting surmisings. New creation... big-bang like... it would be very much like God to do that! Nuclear effects that would need the modern age to more fully reveal!
Not being dogmatic about it, but oh my what investigation down that alley might determine. One of the more astute of the big-bang creation theorists is Hugh Ross at http://www.reasons.org Reasons To Believe. Correlate the big-bang theory with the Shroud — look for identical markers — well, as long as it is to the glory of God not the glory of the investigators, at the worst it is another path that did not pan out.
I am of the opinion that it was not so much a ‘big bang’ creation moment as it was a phase shift to what God has created for those who are in Christ. The realm already existed, Jesus merely left ‘here’ and stepped into ‘there’. He stepped back and forth for forty days following that first step, too. I happen to believe the Christophanies occurred during that forty days before His ascension.
