What If Dark Matter Really Doesn't Exist?

sonar67 writes "According to The Economist: 'It was beautiful, complex and wrong. In 150AD, Ptolemy of Alexandria published his theory of epicycles--the idea that the moon, the sun and the planets moved in circles which were moving in circles which were moving in circles around the Earth. This theory explained the motion of celestial objects to an astonishing degree of precision. It was, however, what computer programmers call a kludge: a dirty, inelegant solution. Some 1,500 years later, Johannes Kepler, a German astronomer, replaced the whole complex edifice with three simple laws. Some people think modern astronomy is based on a kludge similar to Ptolemy's. At the moment, the received wisdom is that the obvious stuff in the universe--stars, planets, gas clouds and so on--is actually only 4% of its total content. About another quarter is so-called cold, dark matter, which is made of different particles from the familiar sort of matter, and can interact with the latter only via gravity. The remaining 70% is even stranger. It is known as dark energy, and acts to push the universe apart. However, the existence of cold, dark matter and dark energy has to be inferred from their effects on the visible, familiar stuff. If something else is actually causing those effects, the whole theoretical edifice would come crashing down.'"

    ...only 7% of scientists believe in a personal god.

    Yeah, good ol' meaningless statistics.

    Guess what? I'm a scientist, I believe in God, and I've *never been surveyed* about it. In fact, most scientists I work with have never been surveyed either, and many of them believe in God as well.

    Why isn't it? Anti-religionists seem to think everything, including anything within religion, should be "provable", no matter what. The underlying problem with this mindset is that (for the most part) religion relies upon faith - so there's no need to rely upon physical evidence. Finding the ark, the shroud of Turin, proving the Red Sea could be parted with scientific facts, does it really matter? Either you believe or you don't. Do you really have to prove God exists before you'll believe?

    Just remember what Pascal said: If you believe and you are wrong, you've at least led a good life; if you believe and you're right, heaven is on your way. If you don't believe and you're right, you've lived your life the way you wanted to; but if you're wrong....which outcomes pan out the best?

    "The USS Make Shit Up"
    ----------------------

    I was stranded on a planet, Just me and Spock
    We met a nasty nazi alien who locked our asses up
    We found a hunk of crystal and a metal piece of bed
    We made a laser phaser gun and shot him in the head

    Bust a move, Tog

    I was standing on the bridge when Sulu came to me
    His eyes were full of tears he said "Captain, can't you see
    the ship is gonna blow do something I beseech"
    I grabbed a tribble and some chewing gum and stopped the warp core breach

    And I say,
    Bounce a graviton particle beam off the main deflector dish
    Thats the way we do things, lad, we're making shit up as we wish
    The Klingons and the Romulans pose no threat to us
    'Cause if we find we're in a bind we just make some shit up

    And though he's just a child, and some think him a twit
    Wesley is the master when it comes to making up some shit
    He's the guy you want with you when you go out in to space
    Now if only he could beam those pimples off his face

    And if you're at a party on the starship Enterprise
    And the karaoke player just plain old up and dies
    Set up a neutrino field inside a can of peas
    Hold on to Geordi's visor and sing into Data's knee

    And I say
    Bounce a graviton particle beam off the main deflector dish
    Thats the way we do things lad, we're making shit up as we wish
    The Klingons and the Romulans pose no threat to us
    'Cause if we find we're in a bind we just make some shit up

    Sisko's on a mission to go no bloody place
    He loiters on a space station above Bajoran space
    The wormhole's opened up and now they come from near and far
    We'll keep the booze but please send back the fucking Jem-hadar

    What is with the Klingons, remember in the day
    They looked like Puerto Ricans and they dressed in gold lame
    Now they look like heavy metal rockers from the dead
    With leather pants and frizzy hair and lobsters on their heads

    And I say
    Bounce a graviton particle beam off the main deflector dish
    Thats the way we do things lad, we're making shit up as we wish
    The Klingons and the Romulans pose no threat to us
    'Cause if we find we're in a bind we just make some shit up

    Well, I was stuck on Voyager, pounding on the door
    When suddently it dawned on me I've seen this show before
    Perhaps I'm in a warp bubble and slightly out of phase
    'Cause it was way back in the sixties when they called it "Lost in Space"

    We were looking for a way to make the ratings soar
    So we orchestrated an encounter with the Borg
    Normally you'd think that that would get us into shit
    But this one has a smashing ass and a lovely set of tits

    And I say
    Bounce a graviton particle beam off the main deflector dish
    Thats the way we do things lad, we're making shit up as we wish
    The Klingons and the Romulans pose no threat to us
    'Cause if we find we're in a bind we're totally screwed but nevermind
    We'll pull something out of our behinds, we just make some shit up
