how stupid is belief that asteroid killed dinos?

2013-02-13 9:56 pm
since the theory was proposed in 1980 to last year it was thought an asteroid collision caused the dinosaurs deaths. but get this, not until 180,000 years later. latest article suggests it may be only 33,000 years later.
can you imagine an event that does effect you for 1000s of years later? its absurd.
更新1:

I am not refuting an asteroid hit nor dinos dieing from it. it is just baffeling that we hear this theory as fact and we are to believe that an event 180,000 yrs ago would effect us today? I suppose you say the first theory had an error range of 1/2 million years to fit the event to happening at the same time?

There was some research a few years back that suggested the two events were seperated by around 300,000 years: http://www.sciencedaily.com/releases/2009/04/090427010803.htm

And there is some research that suggests the Chicxulub crater is not actually an impact crater at all but volcanic (as was originally believed before the asteroid bandwagon started rolling): http://www.ncgt.org/newsletter.php?action=download&id=16

I think you misunderstand the times given.

The recent study does not say that it happened 33000 years later, but happened within a 33000 year window. Having it all happen within 3 minutes would still be consistent within the evidence.

Large dinosaurs were already on the way out. There was a climate change due to massive flood lavas which happened before the asteroid strike and the asteroid strike almost finished them of. It appears that some dinosaurs in what is now Southern Australia which had evolved to withstand cold might have survived for some period afterwards. Southern Australia was once attached to Antarctica.

Dinosaur fossils occur below the K-T boundary. The K-T boundary in most places contains a relatively rich layer of iridium. Iridium is rare on the surface of the Earth but common in asteroids and meteorites. Dinosaur fossils are not seen above this iridium layer.

So explain away the iridium layer.

Well not all Dinosaurs probably died off immediately but cold, lack of food and their inability to adapt to new circumstances led to their demise.
Eventually their breeding threshold was reached and there wasn't enough to comfortably reproduce.
As a species they were finally doomed.

It is a PROVEN FACT that an Asteroid killed the dinosaurs.

They even know where the Asteroid struck.

It left a very very large Crater. Today the Crater is full of water and we call it the Gulf of Mexico.

This sounds like a lame legal defense for a dinosaur. "Your honor, this document clearly proves that I am not dead!"

It's not stupid, it's a very well supported scientific theory.

>>since the theory was proposed in 1980 to last year it was thought an asteroid collision caused the dinosaurs deaths. but get this, not until 180,000 years later. latest article suggests it may be only 33,000 years later.

That's your inability to understand error margins in calculating events. We cannot say exactly what year the asteroid hit, and we cannot say exactly what year the last dinosaur died out. It is also not the case that the impact wiped out all the dinosaurs immediately. Climate change resulting from the impact did that over some considerable time period. It is not absurd, it's just your inability to comprehend the relevant science.

>>I suppose you say the first theory had an error range of 1/2 million years to fit the event to happening at the same time?<<

Not to fit, no. The error range is what it is, and if they overlap there's a good chance the events are related. That's how ALL scientific data is analysed.

Have you ever heard the concept of margin of error? Try to measure your penis with a 0.1% error and then come back.

Well, it was a comet not an asteroid but it would've been more the straw that broke the camels back. The asteroid impact reduced the population enough that they could not survive the climatic changes initiated by the impact as well as by other factors. Eventually, they died out because they could no longer adapt, they lacked the genetic diversity needed and this could easily take tens to hundreds of thousands of years before their final demise. It's said that in extinction, one plus one equals three, the impact is one of many factors that precipitated their demise.

You're misunderstanding the data. The impact scenario was strengthened by those findings, not refuted.

You might want to reconsider acting so arrogant, and calling others "stupid" when it's clear that you're the one who needs to do a little more reading.
