Exploring abrupt climate change and pandemic induced by comets and asteroids during human history

Other Ancient Impacts

Horrifying event witnessed by humans -- Brown University says desert glass is from space -- not "grass fires"
In wake of Halloween last week a very, very scary scientific paper was published. “Widespread glasses generated by cometary fireballs during the late Pleistocene in the Atacama Desert, Chile,” creates a rebuttable presumption that horrific cosmic airbursts — without leaving craters — have indeed occurred in human history, a central contention here at the…
American cosmic airburst in late Roman times revealed by University of Cincinnati
Meteorites, silicious vesicular melt glass, Fe and Si-rich magnetic spherules, positive Ir and Pt anomalies, and burned charcoal-rich Hopewell habitation surfaces demonstrate that a cosmic airburst event occurred over the Ohio River valley during the late Holocene. A comet-shaped earthwork was constructed near the airburst epicenter. Twenty-nine radiocarbon ages demonstrate that the event occurred…
Tusk leaves keyboard for unparalleled excavation in Hashemite Kingdom
This is an easy Monday post. The Tusk was a minor co-author of a paper with extraordinary implications to science and faith published today in Nature’s Scientific Reports. The lengthy journal article has been under development since 2014 when I first traveled to Jordan to join the wonderful Trinity Southwest University at Tall el-Hammam….
Long published field evidence supports Bronze Age Bavarian impact
The Chiemgau impact in Bavarian Germany stands out as a particularly sympathetic “martyr” crater. The evidence for a Bronze Age euro-apocalypse is sincerely published and well established as a legitimate hypothesis based on decades of meticulous fieldwork, but entirely dismissed because the proponents believe the impact was relatively recent in geological terms. The authors…
Hmmm...
Avi Loeb is no household name, but he wants to be. The chairman of the Department of Astronomy at Harvard has appeared on more than 50 podcasts since the start of the year. Given a minimum of one hour per podcast, I’d ask for a week’s pay back if I were Harvard. The guy…
Iturralde Crater may be not be an "impact" crater
…the impactor would have encountered the atmosphere at velocities of approximately 20-50 km/s, and the released energy of the airburst would have been comparable to or greater than any known nuclear explosion. From Wikipedia: The structure was identified on the basis of Landsat imagery in 1985.[2] It is located between the Manupari and Madidi…
Hat tip from Steve Garcia posted December 31st on the Tusk
Only at the Cosmic Tusk can you expect to see a major global announcement by NASA scooped by six weeks. Thanks to our blog’s most dedicated contributor, Steve Garcia: You heard it here first. See other, non-prescient, contemporaneous coverage here: NBC:  Immense crater may have been found deep under Greenland’s ice sheet PhysOrg: NASA finds possible…
A year later, not a word on Alaska paper in Nature with evidence for repeated cataclysm
It’s hard to be cynical enough in this game. I noted today that “Science Communicators,” a recently discussed poorly adapting subspecies, have yet to mention this blockbuster paper in Nature Reports one year ago. Specifically, there is credible preliminary evidence contained by the bucketful that there was a catastrophe prior to the Younger Dryas…
Catastrophic panspermia induces 9 of 10 species within human history
Panspermia 2013 The Tusk recieved an extraordinary paper recently and immediately pinged our digital acquaintance for commentary, world treasure: Dr. Chandra Wickramasinghe. “Chandra, I hope you are well. A friend of the Comet Research Group\YDB team just sent around an announcement of the following discovery: https://phys.org/news/2018-05-gene-survey-reveals-facets-evolution.html A large-scale genetic comparison has discovered that 90%…
Seven Ages Audio Journal
I had a blast last week joining the hosts of my favorite new podcast: Seven Ages Audio Journal. Like the Tusk, veteran podcaster Micah Hanks and his science bros Jason Pentrail and James Waldo attempt the difficult balance between hard science, responsible speculation and perhaps some entertainment. I think they recognized me as a…
