That can happen? Sounds pretty risky. We should have lockdowns.
Manganese crust looks dense and very rich.
What’s it taste like?
Perilously close!? Did our planet survive?
Once you voiced the standard evolutionary 4.5 billion etc.all credibility was lost. Science demands better than fitting unobserved and non repeatable/ testable historical anecdote called evidence to a presumptive narrative..
But anyway. Something did something sometime....
Oops! We missed by it this much ‘’.
I red that last week. It does explain some mysteries in Earth’s climate history.
I’m assuming that I am missing something obvious, but how did these isotopes of manganese and iron traverse the distance between the earth and this supernova in a timeframe that would make it contemporaneous with the supernova event??
Read a paper once that explained how the location of our solar system in one of the arms of the Milky Way was in pretty much the “sweet spot” for the possibility of life on Earth.
For stars located too close to the center of the galaxy, with a relatively heavy population of stars, the occurrence of nearby supernova is too common (even if only a couple of times every million years) to allow the evolution of living systems.
For stars located too far out on the spiral arms, nearby supernovae are too rare to allow the accumulation of significant amounts of elements higher in atomic number than iron - and a variety of those elements are absolute requirements for the kind of living systems found on Earth.
But if you’re in exactly the right location - and their hypothesis was we are - you get just the right occurrence of nearby supernovae to allow the incredbiy long period of time it takes to get to sentient creatures.
Let’s go ask Nancy Pelosi what it looked like.
Were “Women and minorities affected the worst” than white males by this event?
That blowed up real good.
>So not only do we now know that there definitely was a SN explosion in Earth’s vicinity about 2.5 million years ago, we also have the very first detection of the unstable 55Mn isotope.
Typo 53Mn
Oddly enough, this puts it very close to the day of birth of one Nancy Pelosi....hmmmm…….
Looks more like chocolate cream pie
Since nobody was around to see it then it is based 100% on theory.
The cover story for the Hughes Glomar Explorer was it was going to mine manganese nodules from the sea floor.
The real purpose of the ship was to recover the Russian missile sub K-129, from a depth of 18,000 feet:
