We do get tagged quite a bit (like from 100 to 300 tons every day), but we have a layer of atmosphere to thank for the good-sized particles burning up before they thump our noggins.

We could be just as worried about some relatively close star going supernova and flooding our solar system with radiation. Pleasant thought.

If you get me started on theoretical physics, I will be posting bigger messages than Walter Oobleck :)

N.e.o's are relatively common, as grandpa says, it's just that they're too small to do any real damage. I can't remember the average strike rate for objects on the scale of the one that wiped out the dinosaurs, I think every 100 million years maybe?

Yes, they've narrowed it down to that.:grinning:

Way back when...locally here, the navy wanted to bury something or other in the ground so they could communicate with submarines without the subs having to go up to antenna depth...they could remain fast, black and never come back. Project Sanguine...Project Seafarer...and eventually Project Elf...extremely low frequency radio...I think...waves. Anyway, it came and went. There was this show on wimple-radio, WMPL, may it do ya fine, called Hot-Line. People could call in with complaints both large and small. I remember one old lady calling in...this was when it was somewhere between the Sanguine/Seafarer timeline...and she did not want any of those waves interfering with her, no sir. She did not elaborate but I suspect she imagined problems unimaginable. Cue today...when your cell phone can pick up whatever kind of waves are sent your way. The medicines we take do no simply go away. They go into the drain via our systems...and there they migrate to various places, perhaps some of them finding their way to the water supply. What is that, strike two? That's not enough, there was this once in Iowa, Coralville Resevoir, we're building nearby, go down to the water and sing P.J. Harvey tunes and see all these dead fish. Spring. Rain. Run-off. Farmers in the field, go the other way. Friend laughs and says if I'd had some blood work done pre-arrival and another after six months, no wonder what the results would be. Strike three? Then of course you got all the BildungsRomans and that conspiracy, fluoride or something. We can't get no relief.

Ah, we've been hit plenty of times in the distant past, and as has been said we get pelted by relatively small (small car-sized and less) objects every day.
It's possible that there's something rather large out there with our name on it - and according to a quick search it was 2014 DX110 that came within 33,000 miles of Earth, while 2012 DA14 went by at just 17,200 miles from the surface and another late last year came inside the orbit of the moon (at ~215,000 miles) - but FWIW I have a theory that anything really big that can hit us already has.
I'm probably wrong on that score, but I hope I never get to find out for sure. :smile2:

I believe that the Earth will be struck by a meteor gigantic enough to change all of our lives forever. My reason for believing this is that I believe the Bible predicts it in Revelation 8:8...

And the second angel sounded, and as it were a great mountain burning with fire was cast into the sea: and the third part of the sea became blood... (KJV)

You are right, we will be hit again, but my reason for believing it is that space, as unfathomably huge as it is, is packed full of potential missiles. Throw enough stones at a tin can as far away as you can physically throw, blind folded, and eventually you'll hit it. Keep throwing for 4.5 billion years and you will hit it a large number of times.

We are lucky to be smack bang between 2 monsterous gravitational powerhouses - Jupiter and the sun - because they skew meteorites courses often slinging them away, sometimes pulling them into themselves. But not all will be skewed away, some will inevitably come through at the right angle.

Lol so we don't have anything to worry about?
Well, sure.

Supernova in the neighborhood.
Anomalous solar flares that wipe out satellites.
Meteor collisions.
Earthquakes causing nuclear accidents. We've had one recently, and we still aren't grasping its reach.
Supervolcano eruptions.
Viral pathogen pandemic.
Nuclear weapon mishap or terrorist attack.
Zomb... forget it. I'm tired of that one.
Alie.... skip that one too.

Lots to worry about. Always has been. Europeans immediate prior to the 14th century Black Death plague: "Hey, we got anything to worry about?"

That's why we got scotch.

Here another question i was going to ask in here.
Do you guys think there is intelligent life out there?
I say yes. I think it's pretty arrogant of us to think we are the only beings when there are an estimated over 100 billion other galaxies and surely there are planets there that can support life as we know it and define it. But, like Stephen Hawking says, we should hope to heck that they aren't making contact with us, because that makes them more advanced than us and could spell trouble for our little marble.
