Phil Plait - Saturn, Lord of the Rings

shuac says...

^ Interesting, I didn't know that so I looked it up.

http://starryskies.com/articles/2007/10/primal-future-moon.html

In summary:

  • Earth's rotation is being slowed by the friction between the oceans and the ocean floor
  • This will continue until (in a few billion years) Earth's tidal bulges align with an imaginary line running through the center of the Earth/Moon system
  • Earth's rotation will then cease slowing down.
  • when it does happen: Earth's day will be a month long (960 hours a day) and our month will be forty days long
  • those on the Moon looking back at Earth would see the same face of Earth – just as now we see only one face of the Moon.
  • to anyone still on Earth, the Moon will have moved far enough away that it appears much smaller
  • there would be no more solar eclipses

  • Phil Plait - Saturn, Lord of the Rings

    To add to that, as the moon slowly moves away from the Earth, it has a very small braking effect on Earth's rotation. What this means is.. eventually this will lead to both the Earth and the Moon becoming tidally locked, or with the SAME side of the Earth AND Moon permanently facing one another.

    It may be worth looking up how long this is going to take. I'm too lazy to figure it out right now. We're talking a super long time scale.

    It may be such a long time, that either humanity (as we currently know it) will be gone, or maybe our Sun will end it's life by the time that could come about. Something may even disrupt our solar system long before then. Such as our galaxy's destined collision with the Andromeda galaxy.

    I thought that too at first, but I think that's a sign post, or at least someone UP a sign post. Look at 0:40 in fullscreen.

    cuz I'm praying for rain
    I'm praying for tidal waves
    I wanna see the ground give way.
    I wanna watch it all go down.
    Mom please flush it all away.
    I wanna see it go riding down.
    I wanna watch it go right in.
    Watch you flush it all away.

    Run down of tax plans from Obama & McCain

    gwiz665 says...

    Why do presidental candidates HAVE TO change taxes? It seems to me that Americans need to have "tidal taxes" that swing back and forth with each president.

    No, I mean we're not being taxed enough for using fossil fuels. And at the same time, the USA is subsidizing energy industry directly, and giving them tax breaks, and spending billions on a defense budget that involves protecting strategically crucial oil reserves far from the USA. These subsidies probably outweigh the oil taxes.

    In reply to this comment by MarineGunrock:
    >> ^jwray:
    The U.S. should just place a large tax on all fossil fuel consumption, effectively forcing the industry to switch to nuclear/wind/solar/hydro/tidal. A hydro plant with a large reservoir that can regulate its rate of water passage could load-balance with a solar/wind plant.
    It makes perfect sense to tax all consumption of fossil fuels, to internalize the negative externalities of fossil fuel use. The regressivity of this tax could be nullified by a flat refund similar to this year's economic stimulus package.


    You mean you don't think that we are already being taxed on it?

    Windmill Destroyed By Wind

    Farhad2000 says...

    Saying that we should all switch to clean technologies is a very idealistic statement, yes it should be done, but it won't be done in the short term. I personally believe that nuclear power is right now the best short term alternative to continued consumption of fossil fuels, with a long term plan of switching to cleaner technologies.

    Nuclear power can be readily tapped into over the power grids and is substantial enough to supply entire cities, this not true for the various techs like solar, wind and so on. More development is needed in those areas. As for nuclear waste, it is a problematic issue but the waste produced is less readily influential on the environment if stored and disposed off correctly. I have read papers on research to actually break down the waste into something else. Other then that I wouldn't mind sending off a rocket or two to burn up around the sun (just an idea).

    But even then we are replacing one sort of pollution for another, instead of smoke stacks or nuclear waste we would have large wind generation farms, large tidal wave areas in the sea, or large fields of concentrated solar generators.

    However all these technologies still rely on a fossil fuel process for components, so what we term clean technology isn't really because various components are derived from fossil fuels, if not for power in their manufacture then for the manufacture of various parts like plastics and so on.

    The current taxes on oil etc in the USA are far too low.

    Lowest Of The Low "Black Monday"

    "Black Monday" by Lowest of the Low
    http://www.lyricsdownload.com/lowest-of-the-low-black-monday-lyrics.html

    Black Monday is coming around again
    And it feels like a friend that just won't take a hint
    'Cause it's hanging me up
    And it's hanging around

    And I'm feeling far too lost to feel too profound
    When the tone of my voice is the loneliest sound
    My heroes have all become pathetic clowns
    And I'm feeling far too lost to feel too profound

    My friend Kate, you laugh like a tidal wave
    But "Charlie don't surf" on your laughter on Black Mondays
    And the shadows I feel are the shadows in me

    And not even your face or your beautiful smile
    Or the curve of your breasts or your laughing bright eyes
    Could make me believe I'm a winner tonight
    When Monday morning is just out of sight

    I know a story
    About a man who couldn't see past his fingertips
    To reach out and touch it
    Was just too much like he needs it

    And I know a woman
    Who reached out to me and all she got were my barbed-wire hands
    And I won't be too proud
    If she can't depend on me when Black Monday starts coming around

    My friend Kate, you are sad and beautiful
    And the way I am has never been too good for us
    'Cause I'm too blind to hear, and I'm too deaf to see

    But I still have a voice that can call out your name
    With a gut full of beer and a head full of pain
    I can lie in your arms and be lovers again
    And thank God Tuesday morning is just hours away

    Do you know, I won't let you down?
    Rest your head when I come around
    Do you know, you can count on me?
    Laugh out loud, I see what you see

    What If We Had No Moon?

    Farhad2000 says...

    Well the gravitational pull of the moon created tidal waves, think of the primordial ooze of complex molecules that science believes lead to life, the constant movement would create collision between these and lead to more complex molecules forming, thus in my mind leading to more complex life forming.

    The Great Global Warming Swindle - full version

    Doc_M says...

    I'm not a climatologist, but I am a scientist and I'm still on the fence. There's evidence either way. The problem is not the science. The problem is that people, even prominent scientists, are not allowed to argue against it without risk to their reputation and career. Like the video says, if you disagree with what global warming activists say, they ostracize you and accuse you of being an industry stooge. MANY climatologists still support the cyclical warming/cooling theory. One thing is certain though, the vast majority of people who study this don't agree with Al Gore and his 20foot rise in oceans. Even the UN thing only proposes a mild increase. And the thought that there is not debate in science anymore about it is not correct. There is most certainly debate.

    That said, I still support the idea that we should improve our technology to lessen our effect on the planet in general. The fact is that we ARE working on these technologies already. We don't need to create a green religion to make it happen. Panicking about this sort of thing can be problematic. Take ethanol for example. Whoops. How much money has gone into promoting that goof?
    On the up side, wind/river/tidal generators are on the rise and new brilliant ideas are coming out quickly.

    The biggest thing people don't think about is which is true:
    High CO2 --> High Temp.
    High Temp. --> High CO2

    This video displays that consideration very well. The ocean contains a profound amount of CO2. Heating water decreases the amount of gas you can dissolve in it. Warm an ocean and you get a CRAP TON of CO2 pumping out (orders of magnitude higher than human CO2 release).

    good post.
