GPS Will Save Us From Rouge Comets

[zboss]

God forbid everyone's magnetic compass went out of whack for days/weeks and they didn't have good old GPS there as a backup.

But will it do anything about different blue or green comets?

[Don C L]

Personally I like the mauve or pastel comets...

[skipmac]

Darn. You guys beat me to the draw.

Day-um. Everyone's quick on the quip.

As to concerns about equipment functionality during solar fluxes, you can also subscribe to this; but be forewarned, it might make you paranoid: http://www.swpc.noaa.gov/products/al...s-and-warnings

The comet was able to mess with the Mars magnetosphere because Mars has an incredibly weak magnetic field. So weak compasses aren't worth having. In ever so many hundreds of millions or billions of years when the radioactivity of the earth's core subsides enough that the core can solidify then that will happen to us too.

Should I worry about this, I'm 71 years old?

I'm more worried about mascara meteors.

Worry about that? Nah, before that happens so much calcium will have been transported into the mantel by tectonic plate subduction that there won't be enough left on the surface to support life generally.

I'm just sayin'.

We will still have the stars and planets and I have my old Davis plastic sextant. The tropics would be a lot less crowded without GPS.

I'd worry more about the GPS system going down than comets!

Oh, and if you want to put things on your worry list, how about:
(1) the level of CO2 in seawater, raising the acidity of the ocean, killing reefs
(2) the massive trash fields in both the Atlantic and Pacific Ocean
(3) mercury levels in Tuna and other species of fish
(4) melting glaciers, raising sea levels

Ok, I could go on, until I get to the one about the aliens and the Bermuda triangle, but those are already covered in other threads........

I really like this post. When I get into debates with Global Warming deniers, I often say, ''OK, lets just say Global Warming is a myth. We are still Royally ......up Earths environment.'' They usually deny that too.

This is what I suspect a rouge comet might look like.

Now, if you're talking about a rogue comet, that's an entirely different animal.

LOL

I'm 73 and it is worrying the hell out of me. Is it even a topic.
