But most importantly, NASA has admitted there is no simulation available to predict the pieces' trajectory or speed.
Do you have a source for that? I'd like to check it out.
So, there you have it, folks. ISON is just a comet, it poses no danger to earth,
I've been keeping up with these ISON doom porn threads for a while now and, at times, I've wanted to hurl my iPad into a wall out of sheer frustration. The ignorance and blind conviction of some people on here is staggering.
See, I bet if we look back in ATS history this is how it started for Phage, an innocent sincere effort to educate.....lol Well done!

Probably because they don't state "Doom Porn" in the title? Also, they relate to ISON and if you haven't noticed there is plenty of discussion regarding this comet. Therefore, everyone is eager to separate fact from fiction and dispose of the fabrications. Isn't that what this site is about? Also, studying and being able to identify the misinformation only strengthens and distinguishes your understanding of the truth (hence you can quickly identify fallacies and eliminate them when used on the other side of a debate).

I'm sorry, but that's not quite true.
We might not be able to predict exactly how many pieces might form, but we can certainly can tell if they will change orbit or not:
By knowing the comet's mass, and it's velocity, we know how much energy it has.
In order for ANY piece of the comet, no mater it's size in mass, to change orbits, it MUST OVERCOME that energy already there.
And considering the velocity it has right now, the theoretic explosion would need to be on the order of many hundreds of megatons.
Any one (even with out a computer) can sit down and compute how much energy would be released if the entire comet was made up of something that could explode, and figure out how much energy that would impart.
Using the above formula, anyone, with nothing more than pencil and paper, and figure out the amount of energy the comet already has.
And unless your theoretic explosion can exceed the comet's mass times it's velocity (huge right now) squared, divided by 2, the pieces are not going to go anywhere too far from the orbital path it is on.edit on 26-11-2013 by eriktheawful because: (no reason given)
Thanks for clarifying that.
Once again, the truth proves to be far less doom-y than its fictitious counterpart.
