It is suspected that a large swarm of meteors collects in a special resonant orbit. The period of the comets resonant orbit is estimated to be about two thirds that of the dark star's period. Noah's Great Flood was likely caused by Earth impact of one of these long- period comets. Accordingly, a meteor from that comet-swarm may have caused the Great Flood. A meteor from the swarm may have a better opportunity for Earth impact when Nemesis is at its far-point.
Earlier dates are more risky.
Only a concerted effort focused on detection and neutralization of this dangerous comet-swarm can avoid an impending environmental catastrophe of proportions similar to the biblical Great Flood. Another astronomer used a collection of long-period comets' far points to predict two undiscovered planets. One of them has an orbit similar to that proposed for Vulcan. Its orbit is the same in terms of period, inclination and the angle where its orbit cross the common plane of most orbits of the Sun's planets. Vulcan is anticipated to be a dark star about the mass of Jupiter.
