Comets and the Big Bang

It worries me that we are saying that the comets are a problem for the Big Bang. I understood that comets were thought to have condensed when the planets did somehow along with the Sun's birth. If secular astronomers say that, they have a problem with how the comets are still here after so much time and have to postulate the Oort cloud. But I don't believe they would say that comets originated in the Big Bang. I would hate to have us set up a straw man argument when that is what evolutionists do so often. --John Baab 19:57, 16 January 2008 (EST)

Interstellar Comets

I thought the removed comment about 'no interstellar comets' was useful. I believe Danny Faulkner pointed out that we can tell the origins of comets by their orbits, and an interstellar comet would have a hyperbolic orbit instead of an ellipse. Thus, we could tell which comets were from interstellar space and which comets were from the vicinity of the sun. If I recall, the official lists of comet orbits only show one or two comets that might be borderline hyperbolic orbits. If comets are orbiting so far out from stars like the Oort cloud postulates, it would seem that we would have more interstellar comets than we do (this could be wrong). Thus, I believe it would be wise to include something about the lack of interstellar comets. Perhaps an astronomer could help us here. --John Baab 19:57, 16 January 2008 (EST)
