Earth to The Bos and Phil: The true cross-sectional area of the potentially dangerous material is greater than that of the original comet itself

 

The Bos is Back!

Bos Mum on Mars

Update: Coma Just Dust…

Elenin: Sliding Spring backing off a bit…..

Elenin: Probability of Mars Impact 1-120 or so 

These media scientists are just too much. Below is bad astronomer Phil Plait validating the Napier Astronomical Model for the Younger Dryas Impact(s) and refuting The Bos’ claim that there is no way to have multiple incoming bodies explode in the atmosphere. In other words, Phil says just a comet whipping by is enough to unleash some unknown measure of hell on a planet — and it might happen next year.

But Phil Plait has never uttered a word regarding the Younger Dryas Hypothesis. I suspect this is because he so “astronomically correct” and throughly politicized that he has never had an original idea himself, and thus does not appreciate good solutions for problems when those solutions are not part of his canon.

Better to stay quiet than to be proven wrong, right, Phil? Good strategy, considering.

Earth to The Bos and Phil: The true cross-sectional area of the potentially dangerous material is larger than the original comet itself — and this rule applies yesterday, today and tomorrow.

And there’s still more. Comets aren’t generally very solid; you can think of them as loose piles of rubble held together by those ices. As the ice sublimates, the comet dissolves a little, and that rubble can escape. This material, usually [!] objects the size of grains of sand up to small rocks, orbit along very nearly the same path as the comet nucleus itself (which is why we get meteor showers). The gas expands into a large fuzzy cloud around the nucleus, called the coma (which is Latin for hair). Although the nucleus may be a few kilometers in diameter, the coma can be several hundred thousand kilometers across!

What makes this so very interesting is that the coma can be bigger than the predicted distance by which the comet will pass Mars. This means it’s entirely possible, even likely, Mars will pass right through this cloud of material. And the closer the comet gets, the more likely it is Mars will get pelted by the debris set loose from the nucleus itself. If that does happen, it’ll be the gods’ own meteor shower for the red planet.

There’s no plausible mechanism to get airbursts over an entire continent,” said Boslough, a physicist. “For this and other reasons, we conclude that the impact hypothesis is, unfortunately, bogus.”

    “A collision would also be spectacular, but the rovers may not fare so well.”

    One thing that adds to the risk is that the particles will be moving at a very high relative speed. The comet has a hyperbolic, retrograde orbit, so its velocity with respect to Mars will be 56 kilometers per second. Wow.

    A 56 kps impact!!!

    An impact of that velocity og something this large is an extinction event for Martian life…assuming there is any.

    Yeah Flipping Gods –

    Since C/2013 A1 is a hyperbolic comet and moves in a retrograde orbit, its velocity with respect to the planet will be very high, approximately 56 km/s. With the current estimate of the absolute magnitude of the nucleus M2 = 10.3, which might indicate a diameter up to 50 km, the energy of impact might reach the equivalent of staggering 2×10¹º megatonnes! This kind of event can leave a crater 500 km across and 2 km deep. Such an event would overshadow even the famous bombardment of Jupiter by the disintegrated comet Shoemaker–Levy 9 in July 1994, which by some estimates was originally 15 km in diameter.

    We would see the flash of a Martian impact that big on Earth under a noon day sun.

    Comet C/2013 A1 Martian 2014 impact energy budget versus peak human nuclear arsenal megatonnage

    20,000,000,000 C/2013 A1 Martian 2014 impact megatonnage (2X10 to the 10th)
    ……..30,000 Human world wide arsenal peak megatonnage 1972-75

    Orders of magnitude mean things…especially when there are six of them.

    can this large a strike break Mars from it’s current orbit and or it’s position to then to find another orbit?

  • Steve Garcia

    The last 5 minutes of the video are “indirect” views by cams, plus video of damage, as it happened and after.

    In seeing the people while this event occurred, some of them reacted instantly and some seemed to not even notice.

    What I came away with was thinking that those people were lucky – lucky that the object wasn’t any bigger than it was. It gave a glimpse of how quickly people can be affected by such things. Those people could have been incinerated by an object much larger, and they could have done nothing about it. All those big objects still are not known, so we can still be blind-sided.

    Another image that came to mind was Hiroshima. A sudden brilliant burst of light, and then death.

    In this case, no real damage was done. At 12,900 ya or at 536 AD that wasn’t exactly the case.

    “And in a single day and night. . .”

    Or perhaps even more quickly…
