I seem to stand corrected on the plants being dead. I still don't agree that it was the flames that killed them, I would imagine the ash clouds could have, but dead they seem to have been. However, I would still like to know what the plants sprung up again from if they were all dead. Seeds buried in the ground that only emerged once the ash clouds had dissipated? Will look into this more at some later time.

If this is homework, we're not supposed to help by doing your assignments for you. Have you tried running the code yourself? What output did you get? Try running it here, see what it does for yourself: http://codepad.org/ Edit: For clarity, add \n after %d, as such: "%d\n". Also, you'll need to put the code in a main function, just like a real program.

Science programs tend to exaggerate a lot of things. After all, they're made partly for entertainment. The notion that it was "all gone" doesn't hold water. If it was all gone, why do we have plants now (sorry for sounding like a creationist)? I dare say 65 million years is a short span when it comes to evolving new plants from scratch, so there must have been something left. Another sign of this is plants such as fern, that were around from before the event, surviving until present. It might very well be like Moontanman said above, that most mammals were insectivores. This would also allow plants to grow back, since they had nothing that would use them as food until later. But suggesting herbivores didn't survive because there were no plants, I personally have a hard time seeing that.

I'll have to ask for your source on this. While a lot of plants (and animals) died and went extinct, not "all vegetation" was burned to a crisp. If, indeed, all plants were burned, wouldn't it also be likely that animals everywhere were scorched to death as well? Why would the molten rain effect only plants? http://en.wikipedia.org/wiki/Cretaceous%E2%80%93Paleogene_extinction_event#Terrestrial_plants

They're plotting evil schemes. Honestly though, they're cleaning. They first rub their front legs (I guess you could equate it to arms) over their bodies to gather any particles that might be stuck there. The dust sticks to their legs, and they then rub it off their legs, which is what we see when they're rubbing their hands together.

That's a bit optimistic. There are still a range of diseases we don't have a vaccine for. So even if we did use everything in our arsenal, we would still get sick. And that is mostly a good thing. Exposure to germs and other nasty little buggers solidifies our immune systems. Of course, there are some diseases that you really don't want anyway. Also, even if we do had vaccines for everything, I doubt it would be economically sensible to use them for everything, including harmless and mostly harmless diseases. Edit: Oh! And as far as eradicating diseases through vaccination, polio is a good example. But polio was also a very dangerous thing. http://en.wikipedia.org/wiki/Poliomyelitis

Way to comprehend there, stud.

I'm curious - which object has ever been named a black hole for the sole reason of being incredibly bright?

This seems the most accurate for me. Where I'm from, we've mostly discarded the idea of a god, but we haven't exchanged it with aliens in any way. Sure, there are a few who claim to have seen aliens or been abducted, but they don't even have the numbers to be counted as a minority. If anything, it seems to me we (where I live) have exchanged our gods for science, reason, and reality shows.

Sure, since we've found objects very much resembling the black holes that general relativity predicted, through observing their effects on other bodies, gravitational lensing, and the radiation they emit. But then again, I'm guessing that to you, "in the lab" would mean actually putting a black hole in a lab and running tests on it, so I can probably guess what your enlightened comeback will be.

Really? By who?

There's a difference between hypothetical and fictional. You might want to look into that.

You don't exhale pure carbon dioxide. The air around us contain around 20% oxygen. Our bodies convert some of it to carbon dioxide, but our breaths still contain 14-16% oxygen (most accurate number I could find). And since you're basically "pushing" air towards the flame, it gets more oxygen.

Yeah, I got it now. However, see second edit in my last post. It hangs after very few inputs, and gives me an error message saying the program takes too long to respond.

Hello. File "<stdin>", line 1 Hello. ^ SyntaxError: invalid syntax Unknown error. How are you? File "<stdin>", line 1 How are you? ^ SyntaxError: invalid syntax Unknown error. Who are you? File "<stdin>", line 1 Who are you? ^ SyntaxError: invalid syntax Unknown error. This doesn't work. File "<stdin>", line 1 This doesn't work. ^ SyntaxError: invalid syntax Unknown error. Edit: Oh, never mind! I just found the run button. Edit again: I've tried it a few times. And every time, after 2-4 inputs, it hangs up on me.

One could also say that we're all part of this god, since we're all part of the universe. The implications, of course, is that we might as well remove God from the equation.

Am I understanding this right; The nuclear forces in stars are due to gravity because gravity caused the gas clouds to pull themselves together to form stars? Then iron smelting works are responsible for car accidents, because iron is used when building cars.

We are also born with the power to scream real loudly, until our parents wish they had put on a rubber. Doesn't prove there's a god. We'll get back to you on that. Neither answer requires a god though. What makes you think there's a "who"? Why not a "what"?

Starts off well enough. Oh, you dropped the ball that soon! Yes, it's called chance. Let's say we have a bag with 10,000 blue balls and one red. I claim I can pick out the red ball. I reach my hand down the bag and pick out... a blue ball. I do it again. Surely this time, I'll pick out.... another blue ball. Well, let's try this again. And again. And again. And again ad absurdum. Doing this enough times (chances are around 10,000 times), I'm bound to hit the red ball. By your own logic, I can claim I'm psychic, because that's exactly what I predicted. No excuses, that's EXACTLY what you're saying. So basically, I'm psychic because of some quantum reality and relativity. When, in real reality, being psychic is all about flinging as much excrement against a barn door as possible, then see what sticks. You're deluded.

Why would it have "burned up all vegetation"? There was no global-wide fire. The skies were covered with ash and the like, and plants had problems growing. That doesn't mean every single plant died or couldn't grow. The event wasn't black and white to the point that "x died and y lived". Lots of animals died, both carnivores and herbivors, as well as lots of plants. But a lot of everything managed to survive, including plants.

Surprisingly, no.

A crap, I missed the whole running bit! Twice! Sorry, I take it all back.

Can you really assume that? I'd think that if the rain is falling straight down, with no wind (vertically), it would fall from straight above.

Why would you hold it tilted to one side if the rain is coming from above?
