I find his theory very intriguing. It centers around the blood of Christ anointing the right side of seat of the Ark. He believes the Dome of Spirits is the secret entrance to a subterranean passageway leading to where the Ark is hidden. Rood further suggests that the earthquake that occurred at the time of Christ's death, created a crack at the site of the Crucifixion that allowed Christ's blood which flowed from a Roman soldier piercing his side, to fall onto the right side of the Ark hidden directly below the site of the Crucifixion.
That would be miraculous! More likely, the blood of Christ, collected in a challis, was indeed used to anoint the Ark by those of the day who knew its secret location.
May sound far out, but he has put a lot of research into his theories and there seems to be evidence that backs many of his claims.
There is much more to learn in the video as he builds his case. :)
