Good, sensible assessment posted by loveoneanother in #439.

Hello Nick.....thanks for the post and the link

I know this might come across as a little bit 'out-there' but i feel i've been really blessed as a result of this thread. I can't tell you how excited i am to be learning about comets, asteroids, meteors and the like and i really feel that a door has been opened to a greater understanding of how things mesh together. (What an incredible light-bulb moment it's been to discover that comets may actually have been responsible for bringing the building blocks of life to this planet.....i mean, how can one not get excited about the possibilities of that little nugget ! )

Also, in true synchronistic style, a poster always seems to appear on the thread at just the right moment to guide my thinking down yet another amazing path of discovery. To be fair to everyone, i investigate every path put before me with the same adventurous enthusiasm, always excited about the possibilities. Some paths lead into cul-de-sacs but that's ok, it's all part of the enjoyment i get from the journey. Then there are other paths of discovery and understanding that present themselves that take me in just the right direction i need to go at that particular moment in time.

Ever since you first posted on this thread, i've always had this sense you were one of those 'guardians of the knowledge' type posters, possibly holding one of the keys of understanding that i needed to be aware of. I must admit, at first i didn't get it. How the dickens do you get from ham-radios to comets ? Well, you'll be pleased to hear i've been doing my reading and i think i get it. Well, in my own limited way i get it !

I don't want to take the thread too far off the ISON topic so I'll leave it there if that's ok but know you have my thanks for sticking around and for prompting me to look in a certain direction.....it's been much appreciated. Here's a few links and whatnot to some of the stuff i've been reading and looking at.....it's been great and i'm loving every minute of the learning process

(The first quoted piece is an extract of a much bigger tutorial which i'm finding absolutely brilliant in helping to develop my understanding of this fascinating subject. Please use the link that follows the quoted text to read more.....if you're interested in this sort of stuff you won't be disappointed i promise ) :

Meteor scatter or meteor burst communications

Meteor scatter or meteor burst communications use a form of radio communications system that is dependent on radio signals being scattered or reflected by meteor trails.

Meteor scatter communications is a specialized form of propagation that can be successfully used for radio communications over paths that extend up to 1500 or 2000 km.

Meteor scatter or meteor burst communication provides form of radio propagation that can be sued when no other form of radio propagation may be available. While data has to be transmitted in bursts and there may be delays, it provides a very useful form of non-real-time communications that can be used in many circumstances.

Meteor burst/communication basics

Meteor scatter or meteor burst radio communications relies on the fact that meteors continually enter the Earth's atmosphere. As they do so they burn up leaving a trail of ionisation behind them. These trails which typically occur at altitudes between about 85 and 120 km can be used to "reflect" radio signals. In view of the fact that the ionisation trails left by the meteors are small, only minute amounts of the signal are reflected and this means that high powers coupled with sensitive receivers are often necessary.

Meteor scatter propagation uses the fact that vast numbers of meteors enter the Earth's atmosphere. It is estimated that around 10^12 meteors enter the atmosphere each day and these have a total weight of around 10^6 grams.

Fortunately for everyone living below, the vast majority of these meteors are small, and are typically only the size of a grain of sand. It is found that the number of meteors entering the atmosphere is inversely proportional to their size. For a tenfold reduction in size, there is a tenfold increase in the number entering the atmosphere over a given period of time. From this it can be seen that very few large ones enter the atmosphere. Although most are burnt up in the upper atmosphere, there are a very few that are sufficiently large to survive entering the atmosphere and reach the earth.

This is another great place i found that is helping my understanding in how they track meteors that enter the Earth's atmosphere.....

Hi guys....the Earth is now (January 15th) passing under what was ISON's inbound path and as nothing much seems to be happening (quelle surprise!!!) i reckon we're done here

I just wanted to say i look forward to sharing the next NEO roller-coaster ride with you all (well.....there's bound to be another one along soon.....right !)

Here's an amusing blog to end the thread with.....see ya

Comet ISON Fireballs Are Raining Down On Earth



No, they’re not. Really, they’re not.

Although, if you believed everything you watched on YouTube or read on Twitter, Facebook and the “alternative” forums and blogs, you might think that.

But hang on! What about all the reports of fireballs at the moment? They’re everywhere!

Well, yes, there are lots of reports of fireballs at the moment, but a) not a great deal more than usual, and b) they have no connection to Comet ISON at all.

Ha! How do you know?

…because the sky is now monitored very, very closely for fireballs, not just by one group but by many, and if a piece of space rock is observed burning up as it streaks through the sky in a fireball by more than one of these groups the previous orbit of that space rock around the Sun can be calculated, telling us where it came from. If we were being bombarded by debris from Comet ISON those pieces of debris would all be following the same path around the Sun – Comet ISON’s path – but that’s not what we’re seeing. THIS is what we’re seeing…



That chart shows the paths of objects around the Sun which produced fireballs on January 14th. See? All came from different direct directions. No link to ISON.

So, yet again, people who are, at best, totally ignorant about science or are, at worst, deliberately trying to scare and frighten people, are posting utter, utter BS about Comet ISON. If you see a YouTube post or read a Tweet or post on a blog or forum telling you that debris from Comet ISON is raining down on us, a) it’s not, and b) the person who said that is talking total rubbish, either because they just don’t understand the science behind it, or are trying to scare you. Don’t let them. Just remember that these are the same conspiracy theory nutters and fruit loops who predicted oh so confidently that Comet ISON would hit and destroy the Earth, or seed it with plague, or lead to civil unrest, or trigger earthquakes and tsunamis. None of those things happened.

Just remember that the people spreading this rubbish about Comet ISON fireballs are the same whackos who insisted that Comet ISON was a UFO, or a fleet of 3 UFOs, or an alien biosphere full of extraterrestrial ambassadors. Just remember that that the people making these YouTube videos are the same fruit loops who posted videos claiming ISON had turned Mars into a comet, complete with green glowing coma.

They were all wrong, and they were all lying.

And did any of these people apologise for getting it TOTALLY WRONG or LYING when ISON was proven to be JUST A COMET, as scientists had been saying all along? Of course not, don’t be silly.

They’re nutters, seriously. Don’t believe a word they say.

But what about a meteor shower? Will we see one of those?

Ah, now that’s a different matter. We were hopeful that we might see some shooting stars when Earth passed through Comet ISON’s dusty trail, but that now looks unlikely. Why? Well, I’ll let my fellow ISON observer Ian Musgrave explain in his brilliant blog post…

So, please, if you’re worried about fireballs raining down from the sky from what’s left of Comet ISON, don’t be. There’s depressingly little going on now. When Comet ISON fell apart as it rounded the Sun all that was left was a very thin cloud of very small grains of dust, so thin and small that searches by the most dedicated, skilful and patient amateur astronomers in the world, using kick ass telescopes and computers, have turned up nothing, NOTHING. And what’s left of ISON isn’t even anywhere near us, it’s way out of our planet’s orbital plane. Any ISON dust we encounter now was released before the comet rounded the Sun, and, as Ian explains in his blog post, ISON was an unusually ‘undusty’ comet, so there’s not much stuff to go through anyway.

Comet ISON is gone, folks. Let it go. Get out under the sky on the next clear night, look up at the stars, and enjoy the beauty of the universe as it is. There’s no need to decorate or corrupt it with tall tales of fireballs, UFOs or rubbish like that.

@loveoneanother #442. OMG. So true, thank you. But will any of the scaremongers fess up and apologise? Will they ***k.

Will it stop the next lot of mad rantings from those who don't know the difference between a CME, a vapour trail and a comet? Will it ***k.

So, who's spotted the next calamitous non-event for 2014? What is it to be? A coastal inundation from asteroid impact, the final collapse of the world's financial system, destruction of all electrical and communications systems by a massive solar flare, the Earth to swap magnetic poles or even change axis of rotation? Maybe some new unimaginable threat?

OK, I'll be laughing on the other side of my face if any of these happen, but it's a risk I'm prepared to take.

But with all the real wonders, mysteries and threats around us on this blue-green planet, why do we preoccupy our selves with so much made-up bull-sh*t? I don't know, but it just keeps on coming.

Don't forget the Project Avalon's strap-line: "...where science and spirituality meet". Perhaps a bit more science won't do any harm...?
