    if a big enough asteroid were to slam into the ocean i wonder if it would cause half of northamerica and south america and all those other countries to be washed away? I doubt though

    What size is "big enough" ck27? Perhaps a diameter of 1 km? Or 10 km? or 100km? If an asteriod the size of the Moon collided with Earth, what would be the consequences? - say it crashes in the middle of the Pacific ocean.

    The pacific ocean i guess would be a little shallow for the impact of the moon. The tidal forces will be enormous and the earth will bulge towards it. Tides will reach inland as far as hundreds of miles.

    I doubt theres an asteroid the size of the moon though.

    A collision with an object the size of the Moon would generate enough heat to vapourize the oceans entirely. It would also shatter the Earth's crust like a dropped eggshell and melt rock to a depth of several dozen kilometers.

    As with the giant primaeval collision thought to have created the Moon, a significant percentage of Earth's crust and upper mantle mass would no doubt be blasted into space, and quite possibly condense into a second, smaller moon (or more than one). Even if Earth remained more or less in one piece, it would be reduced to a ball of lava wrapped in a cloud of superheated steam - and lose much of its water permanently.

    Come to think of it, an object anything like Moon-sized might not even be able to strike the Earth directly: if it approached gradually rather than head-on, it would be torn to pieces by tidal effects before actual contact was made. We'd get a massive bombardment of fragments instead, which would still render Earth lifeless.

    Something the size of the moon were to hit earth we could kiss every bit of life on this planet goodbye almost instantly

    Makes the Yellowstone supervolcano seem rather like popping a zit by comparison.

    Anyone heard the latest about Tau Ceti: that it has a much greater mass of debris surrounding it than the Sun? Any Earth-sized planet there will probably have endured such sterilizing collisions more than once.

    Too much UV? Tau Ceti is considerably cooler, and more orange in hue, than the Sun: its blackbody emission curve will be further towards the red end of the spectrum, and the UV flux correspondingly LOWER.

    Better to say too much IR.

    I guess if decide to land on one the of the so-called hypothetical planets that may be in the Tau Ceti system and it's close enough, it really doesn't matter how much IR or UV you get........You're going to fry anway!

    Funny how both impacts (the prevalent event in the Tau Ceti system) and supervolcanoes are firey, energetic events - and yet, on a global level, their most widespread effect would be to induce the cold and gloom of a cosmic winter. After fire comes ice, and dark levels all...

    Ever play Chrono Trigger? It's like when Lavos falls from the sky.

    Did you ever see the 50's scifi movie "Chronos"? If you did you would most likely fall out of your seat in the theater!

    Never heard of the movie. Who's in it? Is it anything to do with natural disasters?

    The Scifi 50's movie "Chronos" was so bad that it was funny and you would crack up watching it! That movie was a natural disaster..........

    If I'm still on Earth when the super volcanoe blows than my cover could be blown with the public because I'd have to go to my true body to servive the blast an all that. I know it'll blow soon because it's over due to blow.

    Your true body? Considering the name you've chosen, MewSkitty, are you a Pokemon?

    Given your prodidgous rate of posting so far, you could be the new Jadedflower.

    Mewskitty is not a pocket monster. But it won't survive the Yellowstone blast whatsoever.

    An amusing angle on this story: We've all heard of the "California sliding into the ocean" stories. Many psychics claim the future shoreline will be Nebraska (if you care to listen to psychics). Where do we test our megaton bombs?
    Underground, right? What are these energy releases doing down there? Can they possibly be cracking some underground faults to the extent that Yellowstone might wake up and blow half the US into oblivion. I believe it has been shown that the last "supervolcano" that blew brought the entire human population of this planet down to a measly 10,000 or so. Not that we can do much about it. Maybe ask our great warriors to test their bombs on mars? Jaja
