Massive collapsing stars radiate most of their binding energy (about 10^53 ergs) in the form of neutrinos. The rate of such collapses in our galaxy is expected to be greater, perhaps by a large factor, than the supernova rate. John Bahcall estimates a rate of about one collapse every 11 years in our galaxy. Stellar collapses might not exhibit the conspicuous optical show of full-blown supernovas but can still be potent emitters of neutrinos. According to Juan Collar, recently of the University of South Carolina but now with the University of Paris, stellar-collapse neutrinos may have played a role in biological extinctions on Earth in past eras, notwithstanding their very weak interactions with ordinary matter. Although stellar collapse parameters are poorly known, Collar has ventured to calculate the effect of a hypothetical low-dose, high- linear-energy-transfer (the energy dissipated by a radiation per unit length through a biological sample) neutrino flux on terrestrial animals; he suggests that collapse neutrinos may well cause a catastrophic level of cancerous malignancy, with ensuing large- scale loss of life, at a frequency (on the order of 100 million years) consistent with known major extinctions on Earth.

Which pirate ship? Give me space time coordinates and me and my merry band of time traveling midgets will go and try and save her. Might have to leave Grumpy behind. If we go save her will you babysit Grumpy. Won’t be a second. Heck we can even be back before we leave. If we aren’t back before you expect us, Grumpy is your problem.
Not neutrinos, it was El Caminos what kilt them. They died from eating the Astroturf out of the beds.
“Dont ever ever look into a black hole. If you do the dinosaurs they killed will rush out and eat you.”
That would make the most awesome sci-fi movie!
I see a big problem with this theory.
Wouldn’t Neutrinos wipe out all species equally?
But many species survived this time frame.
The theory would have to explain why many species survived, while others didn’t.
They seem too small and cute to do that
Time for my Neutrino joke:
And the Bartender says, “We don’t serve faster-than-light Neutrinos in here!”...
So a faster-than-light Neutrino walks into a bar...
“Grumpy is your problem”
Oh, you’ve talked to my neighbors.
My Grandma’s pirate ship was the SS Lutefisk.
One word reply:
ZomBeavers
Better than Sharknado in campyness with 99% less production value.
A truly awesome horrible movie. A cult classic without a cult yet.
I went to the Wikipedia entry for "black hole" and then checked out some other languages to see if anything sounded better.
In French it would be "trou noir."
In Indonesian it would be "Lubang hitam."
In Basque it would be "Zulo beltz."
In Turkish it would be "Kara delik."
I kind of like Kara delik. Someone who goes crazy thinking about black holes would be psycho delik.
Hey now, it was a serious offer. My merry band of midgets need the X Y Z and T locations based on the center of the big bang to locate this ship. Everything moves you know. If you can not provide them, I am sending them to a fetishists house that wants them to clean his house in lederhosen. His name is Tod.
I kind of like theories that have some kind of non-kinetic kill-off of dinosaurs, such as a massive burst of radiation or a massive C02 release like the one from the Lake Nyos but on an even huger scale.
I always imagined that if a huge meteorite hit, there would be lots of completely crushed and dismembered dinosaurs instead of ones that got buried slowly in falling particulates, dying of cold and hunger.
Just kind of interesting to consider the alternatives.
But I will say this: A large asteroid strike has to be near the top on the drama scale.
OK.....OK.....
Just a minute......doing the computations.......six carry the three.....the sum of the interior angles.....15% discount for senior citizens......
She’s in the bingo parlor again.
It was taxes by those damned DINOS (Dinosaurs in name only) politicians.
I believe in yer Asiarean their known as "gangnam style."
A course, those guys don't get along with yer ebonicites, so ya might wanna keep lookin'.
Hey! I know her!
Red hat and coat, long curly hair, great mustache, never puts her right foot down....
Yeah, we go WAAAAY back!
Neither the article title nor the excerpted text appear in the 1996 link.
The excerpt actually refers to an old physics paper by Juan Collar that was mentioned in a January 1996 NYT science news story. In the NYT article Collar admits the idea is "purely speculative", and it included the following quote: "As long as we don't take our theories of extinction too seriously they are fun and perhaps even instructive."
The paper was soon criticized for errors and there was no followup.
Ahhhh!!! Codfish soaked in Liquid Plumber.....That stinky tradition ended with my generation in our family.
"Neutrinos, electrically neutral particles that sense only gravity and the weak nuclear force, interact so feebly with matter that 100 trillion zip unimpeded through your body every second. They come in three known types: electron, muon and tau.
Yes it is!
Seems very unlikely.
