    I love this sort of stuff. bunny


    When a huge meteor collided with Earth about 2.5 million years ago and fell into the southern Pacific Ocean it not only could have generated a massive tsunami but also may have plunged the world into the Ice Ages, a new study suggests.

    A team of Australian researchers says that because the Eltanin meteor – which was up to two kilometres across - crashed into deep water, most scientists have not adequately considered either its potential for immediate catastrophic impacts on coastlines around the Pacific rim or its capacity to destabilise the entire planet’s climate system.

    “This is the only known deep-ocean impact event on the planet and it’s largely been forgotten because there’s no obvious giant crater to investigate, as there would have been if it had hit a landmass,” says Professor James Goff, lead author of a forthcoming paper in the Journal of Quaternary Science. Goff is co-director of UNSW’s Australia-Pacific Tsunami Research Centre and Natural Hazards Research Laboratory.


    And from the tsunami modelling:

    5. Concluding statement

    Asteroid and comet impacts into Earth’s oceans are common geologically. Shoemake r et al.(1990) estimated that ‘‘on average’’, a 1-km diameter or larger object strikes the Earth once per 100,000 years. In a given million-year period then, tsunami larger than 100m should shoal over some regional shoreline several times.

    This is cool though. Clever idea. Don't know why nobody thought of it before.

    How Paintballs Could Save Earth from Giant Asteroid Impact

    Quote
    An epic battle between paintballs and a giant asteroid could one day save the Earth from an apocalyptic space rock impact.

    The novel asteroid-deflecting scheme proposes that a cloud of paintballs shot into space could knock a dangerous asteroid off a collision course with Earth.

    Sung Wook Paek, an MIT graduate student, says a spacecraft could fire two rounds of pellets full of white paint powder at an asteroid to cover as much of the rock's surface as possible. The strategy, unveiled Friday (Oct. 26), won the 2012 Move an Asteroid Technical Paper Competition, sponsored by the United Nations' Space Generation Advisory Council.

    The initial force from the paintballs would nudge the asteroid slightly off course, Paek says. And the pale paint job resulting from the splattered pellets would more than double the space rock's sunlight reflectivity. More photons bouncing off the asteroid's surface would enhance solar radiation pressure and bump it further off course.
