    Fact: The Earth goes around the Sun... once every 365.4 days. Not thousands of years.
    ...
    ADD: Earth's speed as it travels around the Sun... approx. 110,000 km per hour (68350.8 mph).

    you are correct but what you're talking about is the EARTHS REVOLUTION.

    what i am talking about is the earths ORBIT in relation to the solar system. every 62 million years we are closest to the edge of our solar system. most scientists agree that this is where we are most likely to get large amounts of radiation and it just so happens that our extinctions are concurrent with this orbit. it is also believed that these times also started mutations and changes in our evolution.
    our orbit is up and down is the universe.

    You understand... our Solar system is made up of 4 terrestrial planets... 4 jovian planets and a dirty ball of ice and rock... and a few other objects revolving around one medium sized star, right? The Earth is in a relativily fixed orbit around the Sun and does not stray towards the edges of the Solar System.
    Are you talking about the sun's movement in the Milky Way Galaxy? Or are you suggestng that the Earth's motion takes it off of the plane of the ecliptic?
    Either way... mass extinctions on Earth have NOT occurred every 62 million years:
    65 Million years ago... a comet took out the dinosaurs.
    200 Million years ago...
    250 Million years ago... the Great Permian Extinction (see previous message for suspected causes)
    360 Million years ago...
    444 Million years ago...
    488 Million years ago... took out the Trilobites.
    ...
    So the extinction pattern is:
    44 M, 84 M, 110 M, 50 M, 145 M, 65 M.

    our orbit moves up and down in relation to the milky way. the 62 million years is when significant changes in evolution took place. all the extinctions (we've had 3) were caused by global warming. the one that wasn't was the extinction that took out the trilobites which some scientists say we were closest to the edge of the milky way and a super nova blast of gamma radiation caused that extinction.
    there's a NAKED SCIENCE program discussing extinctions on the national geographic channel on 11/3 i think you'd really like. it discusses what we've been talking about. :)

    If I'm home and I remember... I'll watch it.
    Otherwise, it takes our Solar System about 250 Milion Years to make one revolution... and this is at a speed of about 220 Kilometers per second. As for affects on out little planet... the Sun and the planet itself exerts the most influence on us. All of Earth's Mass Extinctions have been cause by events on the Earth's surface... not because of it's position in the Universe. These events... comet impact and continental drift... are random in occurrance.
    Sure, someday the galaxy WILL be a major factor... as the Milky Way and Andromeda galaxies collide in a couple of billion years from now... but, by then, the Earth will have probably seen several hundred mass extinctions... if life even survives.
    As for Gamma Ray blasts... Those are servere. If they occur close enough to us... we are doomed. They can blast the complete atmosphere off of the planet... basically turning Earth into Mars. Again... Gamma ray blasts... random events... not run in cycles.

    please try to watch that program. i think we could have a good discussion about it. i saw part of it and TIVO'd it for the 3rd.
    i agree that some scientists believe exactly what you say. i side with the others that believe the permian extinction was global warming after the discovery in greenland in 1998.
    you won't get all scientists to agree about anything. each one has their own theory and different evidence they believe prove it. i guess it all depends which one you side with.

    side note: do you know where roland is? i need to talk to him and he can't receive PMs.

    Let us look.

    Kind of ironic since "Earth" originally meant stationary, unmoving, the centre of the universe.

    we're really flying through our revolution. that's where we had the disagreement. there's a diference between revolution and orbit. i'm trying to find out if a complete orbit is 62 million years; or 124 million years.
