    since all motion is relative (a body can only move in relation to another body, multiple bodies, or a fixed point within a measurable field as viewed by an outside party- another 'body'), one could image the earth as being stationary and the sun traveling around the Earth. Of course, this requires a much more complex imagining of the motions of the other bodies, which is why it is seldom used (it is far simpler and easier {and therfore more useful} to iomagine or solar system from a fixed perspective which imagines the sun as 'stationary' relative to the orbits of the other bodies). However, one could imagine Earth as the stationary body around which Sol moves while the other bodies orbit Sol and, technically, one wouldn't be incorrect, but rather adopting a non-standard frame of reference for the observation of the movement of the heavenly bodies.

    Using this frame of reference, we see that rather than the solar system spinning around a black hole, the black hole orbits the the Earth, getting ever closerand pulling other bodies near to it.

    Standard? Definitely not. Useful? Not really? Needlessly complex a model/visualization? A poor choice for a frame of reference for any real application? Perhaps. But technically not wrong...


    Next week: we all orbit a single electron....

    Let us romove all other bodies from the heavens. How do you know whether the sun or the Earth has is moving? Yo can't tell until you adopt a given framof reference and observe how any given body moves in relation to another body or a fixedpoint.

    It's like asking whether Earth rotates clockwise or counter-clockwise.

    Copernicus is point to his preferred frame of reference

    Challenger has been defeated

    Some interesting statistics:

    Only 47 percent of Americans can correctly answer the question, "How long does it take for the earth to travel around the sun one time?"

    20 percent believe the sun rotates around the Earth.

    20 percent think the Earth circles the sun once a day.

    More than 90% CAN'T explain what a molecule is.

    More than 75% have no clue what thins the ozone layer.

    Only 2% understand what a "scientific theory" is.

    64% have no idea what the "scientific method" is or the meaning of "scientific inquiry".

    40% of Americans feel confident about the leaders in the scientific and medical communities. Less than 12% feel they are knowledgeable about science.

    Less than 40% believe in the science of evolution (more than 80% in all other industrialized nation).

    46% said God created man the way he is now less than 10,000 years ago. Statistic unchanged since 1982.

    63% believe antibiotics kill viruses.

    87% of scientists state that evolution is the result of natural processes with just 32 percent public agreement.

    the near consensus among scientists about global warming is not mirrored in the general public. While 84% of scientists say the earth is getting warmer because of human activity such as burning fossil fuels, just 49% of the public agrees.

    Scientists are the third most respected profession (after the military and teachers) (funny – science gives the military weapons and tells teachers what to say, they good ones anyway)

    77% of scientists agreed with the claim that government scientists were not allowed to report research findings that conflicted with the Bush administration’s point of view.

    By this time, everyone knows that less than 6% of scientists identify themselves as Republican

    Oh, that home schooling.

    The sun orbits the earth once every day
    That's not incorrect, as I have shown ;)

    It does, depending on the frame of reference ;)

    There was a mole in the he Cambridge University Light Entertainment Society who sold the script last year, enabling the3 Stanford team to defeat them in the annual drama competition...

    The Oz One Layer, or Oz: Layer One was the first level of hyperspace accessible throught the Wizard's Tower during last week's acid trip. It was thinned by the increase in pressure in Oz Two Layer brought about by rapid expansion of gasses released from the Lion after eating too much menduo

    The Ory, was a common term of endearment for the orator at the MOLES performance. A scientific ory was a student majoring in any of the physical sciences

    A scientific meth od is when one reaches a given meth batche's ld50. A proper inquiry must be performed utilyzing volunteres to dtermine the specific LD50 of a gfven batch

    This is significantly higher than our recent presidents

    Or that the last president (prior to current) was knowledgeable about English either

    The science of Eve's lotion is a company secret. Rmours still abound, however, that she buys at Wal-mart and puts into plastic bottles from Target.

    32% believe John McCain was there...

    83% suspect these numbers are made up, as no source is cited

    While numerous lab tests show that Eve's lotion is made w/ 100% natural ingredients, 32 percent of people interviewed objected to defining 'natural' as simply 'not supernatural'

    Sears reports record AC sales...

    Yours was the fourth post in this thread..

    32 percent of those scientists were female. Of them, 80% oppose bush and a further 12& responded 'trimmed' or 'landscaped'

    100% of my requests for alink to original; poll have gone unanswered

    93% of Americans don't care

    According to the US government, 2.9% of students are homeschooled, and yet you attribute huge percentages of Americans being ignorant to homeschooling.

    Clearly, YOU learned your math "skills" in public school. :eusa_whistle:

    You can't engage in speculation without any frame of reference. You have to take what is known then hypothesize about what may be.
    It is known that the Earth rotates around the Sun. If you think that perhaps the Universe or our Sun rotates around some larger Universe then you may speculate all you want.

    Or did I just make an "offhand" comment?
