In his book Rocks From Space, O. Robert Norton has a pretty good description of what the impact was like around the globe. The waves generated washed northward to what is now the Dakotas. Pretty much the entire world was set on fire from the heat. I think I’ve read somewhere that those studying the event now think the main object hit at a fairly edge on angle, more tangential, rather than coming more or less straight down from the sky. I’m not entirely sure how something organic or living could survive intact the forces involved if it were knocked literally from Earth’s surface in to space. That’s an interesting thought. Something that does not make sense with that hypothesis is that the meteor that struck in what is now known as the Yucatan, hit the ocean, not land. How would this lead to worldwide fires, and the supermassive tsunami that would have formed would have doused any fires. |

How would this lead to worldwide fires, and the supermassive tsunami that would have formed would have doused any fires. I suspect that something estimated to be about 6 miles in diameter with an impact velocity of 12 miles per second is going to generate enough heat to vaporize a good bit of the water at and around the impact zone. That probably reduces the wave by a bit. It seems I read somewhere that the wave reached only as far as the I-20 / I-30 line in Texas. The heat and air wave from the blast reaching further. That and the heated ejecta was thrown out higher and further than the wave reached. It seems some of the amino acids can survive a high heat exposure. |

I have also read that a small fraction (∼12%) of material ejected from Chicxulub completely escaped Earth. Apparently, the fires were started by all the static electricity from the debris around the globe. The debris from the Chicxulub impact "deposited a tremendous amount of energy into the atmosphere. Power levels in excess of 37.5 kW/m2 for more than 20 minutes in the atmosphere produced ground-level power levels in excess of 12.5 kW/m2, which was sufficient to ignite wildfires on several continents." agupubs.onlinelibrary.wiley.com/doi/10.1029/2001JE001532Sounds like the lightning was beyond imagination. |

vegasjames HankRocks geoff59 1dave hummingbirdstones RWA3006 Pat The 'unusual meteorite crashed in a Costa Rican rainforest' may not be so much be an 'unusual event' but instead an event rare for modern humans to observe and be able to analysis what has come down to Earth from space... No doubt, there are some unusual, and alien looking creatures, in the oceans today... from somewhere over time. Many strange things show up in our most beautiful rock formations... agate and other mineral specimens today... some from formally living organisms and geologic processes many millions of years ago. Everything has come from 'space' at some time in the past, no? I believe God is pretty big.

vegasjames HankRocks geoff59 1dave hummingbirdstones RWA3006 Pat Over the history of space rocks impacting Earth, the 'unusual meteorite crashed in a Costa Rican rainforest' may not be so much be an 'unusual event' but instead an event rare for modern humans to observe and be able to analysis... probably a good thing we can, I believe. No doubt, there are some unusual, and alien looking creatures, in the oceans today... from somewhere over time. Many strange things show up in our most beautiful rock formations... agate and other mineral specimens today... some from formally living organisms and geologic processes many millions of years ago. Everything has come from 'space' at some time in the past, no? I believe God is pretty big. Yes, before Earth formed an atmosphere the Earth was hit much more frequently by meteors. It is even believed that our moon was formed by a planetary body colliding with the still molten Earth ejecting a large part of the molten Earth that out where it condensed in to the moon.
Octopi are considered by some scientists to be alien creatures.
Technically, Earth is a space rock as we are floating around in space.

I'd sure like to see and comprehend it all. |

Interesting article there about the unusual genetics. There are many things deep in the sea that have yet to be discovered or studied. Who knows what has evolved down there in the dark cold... perhaps something unusual derived from material riding a rock from space. These creatures' ancestors' remnants were siliconized in some of the most beautiful stones we polish. It's hard to image the time scale of things. www.montereybayaquarium.org/stories/deep-sea-creatures |

It is a rare treat to see them out scuba diving. Partially because they blend in so well.
