Tsunami Hit New York City Region In 300 BC

Hugh Pickens writes "Scientists say that sedimentary deposits from more than 20 cores in New York and New Jersey indicate a huge wave crashed into the New York City region 2,300 years ago, dumping sediment and shells across Long Island and New Jersey and casting wood debris far up the Hudson River. Steven Goodbred, an Earth scientist at Vanderbilt University, says that size and distribution of material would require a high velocity wave and strong currents to move it, and it is unlikely that short bursts produced in a storm would suffice. 'If we're wrong, it was one heck of a storm,' says Goodbred. An Atlantic tsunami is rare but not inconceivable, says Neal Driscoll, a geologist from Scripps Institution of Oceanography, who is not associated with the research. The 1929 Grand Banks tsunami in Newfoundland killed more than two dozen people and snapped many transatlantic cables, and was set in motion by a submarine landslide set off by an earthquake."

    Your analogy is REALLY flawed. Being Black doesn't imply a certain rational framework, or adherence to a certain theory. As far as I know, no ethnicity has a defining body of theory, that once they change their minds, they change their race.

    I just stopped believing that the Earth Revolves around the Sun, therefor I ceased to be white.

    Your statement is rather silly, since basically your saying that no group that holds a view contrary to science, reason, or evidence, should be discredited, even if this opens a very large can of worms, since there are so many contradictory views. This is especially true when you make a statement of an ontic nature, which is falsifiable such as the claims of the young earthers. Either the world is 3000 years old, or it isn't, and proof would exist that would prove or disprove one or the other claim. Faith never plays into it.

    Intolerance would be saying "never tolerate religious group x", which is almost as bad as racism, even if it is much more prevalent than racism. Though oddly religious groups seem much less tolerant than anyone else, since your are a bad bad person if you don't align with their sexual, social, or ideological mores.

    I have nothing against religion, or the religious as long as they don't try to muck with my life, or tell me what do based on what their supreme deity of choice told them, since that argument has no bearing on my life. If they keep their ideas away from me, I'll happily ignore them. UNTIL, that is, they try to pass of faith for reason because of religious arguments. The second they say something disprovable, it is fair game, and they shouldn't complain when someone attacks it with evidence, science, and reason.

    I cannot scientifically disprove God or gods, but I can easily disprove the world being 3000 years old, or similar claims.

    There is no right to be wrong, especially when you try to spread falsehood as unassailable truth (there is no such thing as an unassailable truth, truth should be attacked at every chance we have, just to make sure truth is REALLY truth, and some some pleasing falsehood that makes us happy).

    Umm, sorry you got the math wrong.

    It is the tsunami WAVE that travels at 1000km/h. There is no way the water itself travels at that speed. (It is almost the speed of sound. Do you really believe tsunami waves cause ocean to fly hypersonic?)

    Think of the sound: it travels at 340m/s, which does NOT mean that the medium (air) travels at that speed.

    The correct way to estimate tsunami's energy, I believe, is to calculate its *potential* energy. I.e., (200km*pi*1m^2)*1000kg/m^3 * 9.8m/s^2 * (roughly) 0.5m = 3*10^9 J.

    Multiply by 2, because waves tend to have 50:50 mix of potential & kinetic energy, if my memory of classical mechanics is correct.
