No, ISON is not going to spread the "black death" on earth.

But what if the super doomy black death comet-ey germs are protected by some kind of alien deep-space protecto-varnish that lets them survive their intergalactic plague spreading travels??

The protecto-varnish burns up in the atmosphere.....THEN revealing the doomy plague that is THEN succeptable to UV light.?

I swear, some superstitions just won't die. No, comet ISON's dust is not going to infect us with "the black death" better known as Yersinia pestis. Few organisms can survive the harsh conditions of outer space. Some extremophiles can, but the most "space worthy" organisms on earth are not sources of plague. Some of the largest sources for potential interplanetary contamination by our own probes traveling to places like the moon, for example, are about organisms hidden inside the spacecraft or in compartments that are shielded from the sun's unfiltered UV light.

It wouldn't stand a chance floating along attached to a cometary dust particle in space. And yes, the dust that reaches us from ISON (if any at all - the thing is under-performing expectations) will be quite small.

As you can see, if you solve for dust grain size, it is inversely proportional to the acceleration it experiences relative to the comet. The reason is simple; the dust tail is formed by solar radiation pressure, which has a greater influence over smaller particles. If a particle were to have left ISON on January 1, 2012, well before it was even discovered, and at a sun distance in excess of 8.6 AUs, it would need a total delta-V (change in velocity) of about 2265 m/s to reach earth on January 12, 2014, when we are potentially going to encounter some of ISON's dust.

(I manually set the virtual spacecraft in the sim to the exact same state vectors as ISON for that time, then saw how much delta-V was needed to reach earth on January 12, 2014 - the number is listed under dV applied as Tot and is in m/s - I tested it to make sure the course actually did bring the test particle to earth on January 12 2014)

That's 64195200 seconds later. For the sake of simplicity, let's say that the acceleration needed (alpha in the above formula) is simply the delta-V divided by the time to reach earth (it's really more than that - the closer it gets to earth, the more delta-V is needed to adjust the course to reach earth from the course the nucleus is on, so we're being generous to the final grain size in this assumption). That works out to an alpha of 3.528x10^-5 m/s^2. Solving for the dust grain size, that works out to about 10 microns. That is about the size of the dust grains that can therefore be expected to reach us on January 12th, provided there are enough particles of that size and accelerated by the sun's light along the right velocity vector to ultimately reach us.

Here allow me to prove you are full of shit!

Dear DR Astro,

don't take this the wrong way,

but you sir, are a firkin idiot.


stop talking about Yersinia pestis ,

this is an hearsay, you can find it in any medical book.

Dear DR Astro,

whats in question are,

1, the plagues happened after comets was seen, these comets were so bright, that people looked up, they where seen in the daylight, and night for days at a time,

2, the plague symptoms are the same as radiation poisoning,

3, comets have been found to soak in radiation from, either the SUN, or Cosmic Particles,

read this, quote," A team of U.S. and German astrophysicists have made the first ever detection of X-rays coming from a comet. Their discovery of a strong radiation signal -- about 100 times brighter than even the most optimistic predictions --

[link to heasarc.gsfc.nasa.gov]


so if you can stop talking crap for once in your life, and answer the firking questions,

(1) is it possible that comet ISON, is charging its self up with radiation,

(2) and that when we go through the so called dust of comet ISON, that the whole Earth could quite possibly end up with millions of people with Radiation poisoning,

you work on facts i presume,


the facts that the plagues followed closely by bright comets seen in the skys for days and days,
everyone looking up and seeing them.

paintings about them, books, writings all about it,

or are you going to fall back on the medical books to try and bulshit me into believing all those people died around the world because of a bacteria,
carried on a god damn rat,

no rats in iceland, yet they still got the plague,

theres a hole in your logic'
you who know all the answers,
you say that science is magic,
and you expect me to buy it,

this isn't fear mongering, this could be closer to the truth than you might think,

but your a loyal member of society,
who believes what he is told,

so once again you will pull the veil back down over the eyes of the people who are in the process of waking up to the truth,

which is so far away from your truth its scary,

Astro FAIL!

I expect a full apology from both of you in January.

I don't apologize to nobody. They apologize to me.

Everything is possible Mr. Astro.

It doesnt reads like this has to happen or will happen..but it could happen.

Then at least be willing to put your money where your mouth is. I agree to stop posting on GLP forever if your doom materializes and ISON poisons "millions of people with radiation poisoning." Will you agree to stop posting here forever if your doom doesn't come true?

Fat chance.

I see, so you lack the courage of your convictions. Thank you.

But, you are just wrong when you say that viruses, bacteria etc. cant survive in space.

Glad you agree.

I have great respect for you Dr Astro but, how the fuck would you know?

What? That you never make any sense?
