If the fireball was seen from Maryland to Boston, that must have been a BIG chunk of rock.

You'd probably be shocked at how tiny the rock really was.

1) These things are moving at incredible speeds

2) They are incredibly high up, probably 20 times higher than they "look." When one of these disappears from view over the horizon people will absolutely insist it must have hit "just over the next hill" when in reality it never got closer than 60 miles to the ground.

Not a single poster took this seriously as a grave threat to life on this planet. Who did your lobotomy?

So what would a serious person do about it?

Oh, I'm well aware that it was likely 60-100 miles up. That's my point -- that it was emitting luminous energy visible from 100 miles away, along a track that stretched hundreds of miles. That's a lot of kinetic energy, indicating something significantly bigger than a bread basket (but most likely much smaller than the Russian meteor).

"There is no "our way". The only thing that could cause an increased incident of meteors is if somehow there is more debris everywhere, not just here."

Arguably, there is no, "our way". There is however, "our vicinity." Think of a flak explosion from a single WWII anti-aircraft shell. When it would detonate in proximity to an aircraft, it would send shards of shrapnel in all directions, with just as many shards blasting directly away from the aircraft as directly towards it at the instant of detonation. Since the aircraft was in continuous motion as well, those shards that may have been projected directly at the aircraft at the moment of detonation were no longer moving directly at the aircraft the instant after, but rather at something of an oblique, so in that regard, I suppose you could technically state there was no true, "our way."

Having said that, some areas of the European sky were far more heaviily defended by flak than others, and I'm not sure you would have been able to persuade any pilots to fly into high densities of flak by explaining to them that none of the shards of shrapnel were really going to be headed "their way," or that the overwhelming majority of the shrapnel in each shell would in fact be blasting "away" from them.

You could read Lucifer's Hammer for a depiction of how the planet would likely react to an NEO object actually striking, and how the surviving populace would react.

Then develop a plan in the back of your mind in the event an NEO likely strike.

Which brings us to the heart of the problem with asteroid defenses: the Klendathu, they are us. The capability to deploy asteroid defenses and/or the capability t o mine asteroids also confers the capability to use asteroids to bombard and destroy most life on the Earth. This is an upcoming problem which is already becoming a topic for international disputes.

You’re probably joking but I’ve had a vague, lurking suspicion that we’ve entered a cyclical period of high frequency for this sort of thing. Some will say we’re seeing more because more people are looking, that awareness is heightened, sort of like that “summer of the shark” hysteria of a few years back. Don’t know about that.

I do know this sort of video comes in almost every week now to the point that formerly very uncommon sightings of larger meteors or “fireballs” are now not so uncommon. The Mayans appear to have been bloodthirsty pagans who practiced human sacrifice among other social niceties, so they’re easily dismissed by presumably advanced societies such as ours. But, they were very advanced in astronomy, all else aside. The “end of an age” might just build slowly for all we know.

And calendars and time it would seem. Perhaps a cycle that we’re just now finding out?

That’s a pretty good disagreement, by the way. I’m aware of all this but my context was based on the presumed assumption that the frequency of meteors is increasing long-term. For that to occur there would need to be more meteors everywhere in the inner solar system, not just in the vicinity of Earth. I’m sure you can agree with that.

Most everyone should read ‘Lucifer’s Hammer’ at some point in their adult lives. I’m not sure we, as a country, have enough good people left that would be able to continue to ‘control the lightening’.

Actually I stopped in the middle of that book because I found it too depressing. I’ve been meaning to take it up again, however. Notice how the chances went from millions to 1, then to thousands, then to hundreds, and then they stopped reporting the odds altogether. Nevertheless, the odds are still millions to 1 of a real occurance within our lifetimes.

It IS a depressing book. But the ending isn’t all that bad considering how it could have turned out. The antagonists are not dissimilar than those in ‘One Second After’.

I spent a while trying to figure out how far inland a 1500ft tsunami in the GOM would actually go.

Alright then, I don’t want a spoiler but the hint of a better ending helps. If you want to read a real depressing book that is not fiction, I suggest “The Black Book of Communism”. It’s highly peer-reviewed and riddled with ugly details. I’m forcing myself to read it but I don’t want to.

I saw this thing! It crossed over Manhattan a bit south of me as I was walking down Broadway in the high nineties. It went from west to east and looked greenish, like a neon green, and then it appeared to burn out and disappear, like a huge shooting star.

It looked like it was only a few blocks south of me. Quite low in the sky. But the article says these things are deceiving.

I stopped in my tracks and said “What the he!! was that!” No one else had noticed it. I told someone later I thought I saw a drone.

It would go up the Colorado river and create *another* sea in the Hill Country... but probably also splash North past Waco.

By the way there’s supposed to be a comet late this year, brighter than the moon for what they say. If it survives that is, since it’s sun-grazer. Don’t know how many know this yet. Comet Ison.

Pressure the government to repurpose our ICBM arsenal. It’s the only defense we have at present. Then support the Russian initiative that is presently being discussed to make this an international priority.

“That’s a pretty good disagreement, by the way. I’m aware of all this but my context was based on the presumed assumption that the frequency of meteors is increasing long-term.”

The evidence tends to indicate that is a subjective and a false assumption. If by long term you mean the long term experience of the Solar System, then the assumption must be in gross error, because we have obvious evidence that there has been no reoccurrence of the Late Heavy Bombardment in the Solar System. Secondly, the existence of the inner planets of the Solar System make it self-evident that their coming into existence increasingly thinned out the population of matter within their gravitational influences over time. This decrease in the frequency of bombardments overall is corroborated by the ages, sizes, and frequencies of crater formation on the bodies with little or no atmosphere or plate tectonics.

In the case of shorter time periods measured in decades, centuries, millenia, and millions of years, any presently undetermined variations in bombardment frequencies can be attributed to disruptions of the Oort Cloud by stars passing close by the Solar System, collisions in the Oort Cloud and the Asteroid Belt, and perhaps encounters with interstellar debris fields. In each case, the variations in meteor populations would still be governed by non-uniform distributions resulting from natural forces.

Within the period of human history, there is no evidence that one period of time experienced a greater frequency of bombardment oveerall than another period, but it can be inferred there likely should have been due to encounters with meteor showers as a consequence of coincidence with the orbital paths of comets and asteroids.

In the last hald century, the counts of crater formation on Luna and Mars doees not indicate any significant changes in bombardemnt frequencies.

“For that to occur there would need to be more meteors everywhere in the inner solar system, not just in the vicinity of Earth. I’m sure you can agree with that.”

On the contrary, you are postulating a distribution of the meteors in the inner Solar System which cannot exist in the preseence of the Solar gravitational field, the planetary gravitational fields, the forces of the Solar Wind, and electro-static forces. The planets formed as they did due to the harmonic wave distributions resulting from the gravitational forces, Solar Wind forces, and electro-static forces; see Bode’s Law. There is every reason to expect an interstellar debris field would not have a relativley eveen distribution of meteors in a field the size of the inner Solar System. Even if there did exist such a debris filed and the Solar System encountered it while orbiing the hub of the Milky Way Galaxy, such a debris field would become disrupted and non-uniform in distribution upon encountering the gravitational fields of the Solar System and long before passing through the Oort Cloud on its way into the outer Solar System. The inner Solar System would then encounter the disrupted population of meteors as a series of streams or torrents between quiet periods between those streams and torrents. Again, the debris filed could not enter the inner solar system as an intact field of meteors. You simply cannot have “more meteors everywhere in the inner solar system” because the various mentioned forces remove them from some regions of sapce eveen before they can arrive in the inner Solar System. Any new debris field created within the inner Solar System by something like a collision between asteroids will immediately begin to dissipate into a non-uniform pattern due to the differences in the forces acting upon them.

You may want to familiarize yourself with the Shiva Hypothesis.

"This cycle of doom has relevance to the present-day impact hazard, as the Solar System passed through the Galaxy's central plane in the last few million years, and by some accounts a barrage of comets recently dislodged from the Oort Cloud should be approaching the planets now. "

What is old has become new again, at least with respect to the authors of those articles. The concept that the mass extinctions are due to periodic passages of the Solar System through the galactic plane has been around for more than a half century. I’ve been a proponent of the idea for that long. Science is beginning to catch up with the speculation in the last couple of decades, but they still have a way to go with the presentation of empirical evidence to support our earlier speculations.

In addition to the evidence of iridium, other tracers are coming into use such as fullerenes or Bucky Balls, extraterrestrial osmium, and other novel approaches. There is a probable mega impact site likely buried under the Antarctic icecap for one example to be proven.

Another speculation used in science fiction and now gaining more interest in science is the likeliehood of the existencee of rogue planets in interstellar space between the stars. These are planets who do not orbit a star or orbit a brown dwarf and or each other in the vast spaces between the visible stars. It is already known that stars have come close enough to the Soalr System in past ages to gravitaionally disturb the Oort Cloud, but intersteellar rogue planets remain undiscovered and speculative for the present time. Their existence near the Oort Cloud would certainly greatly increase the opportunities for destrablizing the orbits of objects in the Oort Cloud. So, it would appear we have barely scratched the surfacee of some very real possibilities for objects that could be responsible for raining destruction upon the inner Solar Systeem upon occasion.

I saw it! I was driving home in south-eastern PA. Suddenly there was a quick flash, and I watched it as it flared for about three seconds then went out. At first I thought it was a jet on fire, then realized it was going way too fast. I then thought I’d never seen a meteor that size and gunned the engine to get to a valley, because that was going to be like a nuclear blast if it hit land.

Some of the geological papers have suggested the tsunami from the Dinosaur killer made it as far upstream in the Mississippi River Valley as Southern Illinois and St. Louis, Missouri or higher. Along the gulf Coast it supposedly went inland into the lower halves of the states.

I can believe that. The Mississippi embayment was a shallow sea then wasn’t it? Wonder how far it would travel with the current coastline.

Really, I was talikng in terms of more reasonable proportions. A change in the number of meteors over the course of a few years, not millions or billions of them. And for such an increase, they would have to be more or less scattered randomly through the inner solar system. I didn't say exactly evenly distributed. This, I'm saying only because there have been suggestions that we are getting more meteors as of late.
