Sweet, i'll have to check em out.
So guys, I refuse to let this thread die, lets talk about something you guys think is cool/interesting....anyone got anything they want to discuss? if not i can always find something to ramble on about like i normally do. lol. How about one of these-
Tunguska
The yellowstone super volcano
The asteroid that was given almost all the responsibility for the dinosaur extinction and the new evidence that puts that in doubt.
The altering of dna by viruses and how they influence evolution.
The Yellowstone Caldera, now that is a scary thing!
I have read that if that thing erupts, it is pretty much goodbye to the majority of life as we know it.
And as for your thoughts on Dinosaur extinction, and the programme you watched on........nat geo was it?? What other examples do they give for the extinction, I mean, I haven't seen the programme but in my opinion it was a whole heap of things, but it was the asteroid that triggered most of it.
One of the worlds largest crater holes (this is from memory so I don't mind if someone wants to correct me) is in Mexico and it meassure's 170 kilometers in diameter. I'm no good at maths but that must be about 120km from one side to the other. Now that is huuuuuuuuuuuge, so, on impact anything within 2000km give or take is practically dead, and most likely instantly, once the inicial impact has happened, the rest is leathal gases and radiation poisoning, killing most wild life, and trees ect...now in my opinon that would still not kill off everything, but the impact itself would most likely trigger massive earthquakes disrupting tectonic plate movement and in turn triggering volcanic eruptions, and big ones. Blowing hot ash in to the air and covering the surrounding land in meters and meters of ash, whatever doesn't die from suffocation incially will die eventually from the poisoning from breathing the toxic air.
There are many more factors to it, but that is a simplified version, and if anyone wants to build on it. feel free! So yeah, I'm interested to know what they are thinking killed the dinosaurs now! Please, if you have time let me know.
Darkdestruction420 when and if you have time, and enjoy reading you HAVE to read Bill Bryson's "A short history of almost everything" It is so full of information about these soughts of things!! And the way he has written the book makes it totally comprehensive! It is an easy read for whoever is interested. Such a cool book!
Anyway thats my 2 cents, anyone wanna pitch in!??
Now this is my opinion with a few scientific "facts" in there aswell, I am not claiming that this is exactly what happened, it is basically what i have come up with just thinking about it, and reading heaps.
