Replying to Comet ISON

I hope this guy is right. Though he may be downplaying the comet's potential. It is feasible to believe that an object big enough, could cause possible damage if in fact that object makes impact. Possible impact without anyone noticing? Look at what happened in Russia. Plus, it is rather hard to rely on NASA solely because of lack of info and non-disclosure issues. ISON has the potential to cause meteor showers, I mean ISON is certainty larger than Haley's comet, which every year causes the Leonid showers.




and what if Mars altered its path just a fraction of a percent? Couldn't this cause its returning course to differ significantly than what was perviously stated?


Me bought a telescope.

I'm not a scientist, so I know little to nothing and I mean nothing, not just science but cooking, everything, I am just fascinated by comets. Does anyone know anything about this comet?
