Did a Cosmic Impact 12,800 Years Ago Actually Happen? A Younger Dryas Impact Hypothesis Review
发布时间 2022-07-23 18:05:27 来源
摘要
When we think of the Younger Dryas, the cold period that began around 12,800 years ago and ended around 11,600 years ago, most of us will instantly think of a cosmic impact event.
But the Younger Dryas Impact is still a hypothesis, a hypothesis being a suggested explanation for an observable phenomenon, or a reasoned prediction. To be upgraded to a theory, it needs to be a tested, well-substantiated, unifying explanation for a set of verified, proven factors.
Now to many people, the call for it to be called The Younger Dryas Impact Theory has already been made yet the vast amounts of work done, by various teams of scientists on Younger Dryas Boundary sediments are still not unifying.
In this video I try to condense the main points and evidence for and also against the impact hypothesis (YDIH), knowing full well this medium is not a peer reviewed paper, so forgive me for being brief, leaving out some detail and evidence, but believe me when I say I’ve spend most of this week reading literally hundreds and hundreds of pages of scientific papers on this subject, hence a lack of videos.
Now, as a disclaimer, this video was extremely hard to research and make and because there are so many papers on the subject, so many interpretations of the data, so many disagreements, arguments, opinions and so on, well I tried my best to give an honest impartial take. If I get anything wrong, factually, not regarding your opinion or interpretation, please get in touch.
