Humans have been around far longer than 11,000 years.

You have no idea what you are talking about.

My point wasn't about radiocarbon dating. Or Argon isotope dating for that matter. Anyway, doesn't matter. I don't need to be in this thread.

I think it is a safe bet that by the time we are faced with this possibility (assuming we are still around by then), we will have advanced enough technologically to handle it. We are aware of the danger and there are people that are trying to solve this already. There was news quite recently about someone that had developed a theoretical solution already.

There are plenty of potential solutions that would be viable with today's technology. We would just need significant warning.

I didn't really see anyone implying that our technology is stagnant.

This article was just an announcement, and it's all over various news outlets.

There will no doubt be papers published in scientific journals, plus much review, debate, and further testing.

I know, but how are we supposed to take your criticisms seriously if your arguments and examples are all wrong?

If these numbers (which is a range, with a margin of error that is well within the capabilities of the tests used) are verified, they will be fact; as in we will be able to prove that the Chicxulub impact occured at a very specific (geologically speaking) time.

We already have several other facts on hand, namely that the Chicxulub event was an impact of an object 10+km in diameter, and that dinosaurs effectively disappeared from the fossil record at around this time.

If we can closely place the extinction event and the impact event, it will be nearly inconceivable that such an impact did not play a significant role.

Pretty sweet article. Can't say the dinosaurs didn't deserve it. Especially that disgusting Titanaboa. Snakes should never get that large, ever. Disgusting! biggrin.gif
