I thought that the one that landed just off the Yucatan Peninsula was responsible for offing the dinos?

Yap.. that was only a small one... about 16km in diameter. Crater is about 175km across.

The "wall of fire" is just conservation of energy.  All that massive kinetic energy has to go somewhere. Most of it goes into ignition. The wall part comes from conversion of momentum. It aint just gonna stop moving cuz the earth is in the way- it'll just go around us. Hence the "wall"...

I guess you have to think about how big this rock really is. We're talking like 300 miles long. That mean when it actually hits us
the other end is still way out in outer space. This rock is the size of the state of Washintonish. I watched the vid and thought the scale seemed
off until I thought more about it. It would be amazing to watch that make the beast with two backser come though.

i wonder if there would be enough time for tidal reactions prior to impact?

[NAKID]

It would likely be flash boiling the ocean immediately before impact..

That is my favorite Pink Floyd album by far.

It would only be cool to have the Floyd playing at the end of time if Roger was playing with them.
