Raechard -> RE: If you were a Science Teacher.... (7/8/2007 8:15:29 AM)

...but would not the location of earth be needed as its a key datum point you are measuring from. So earth would either have to be at the centre or the edge of the universe right?




Raechard -> RE: If you were a Science Teacher.... (7/8/2007 8:29:56 AM)

You need two formulas as there are two unknowns. Formula one will give the relationship of earth to the edge or centre of the universe. Formula two will give you the distance accross the universe by substituting formula one for one of the unknowns. etc. zzzzzzzzzzzzzzzzzzzzzzzzzzzzzz.




mnottertail -> RE: If you were a Science Teacher.... (7/8/2007 9:18:17 AM)

the center is a moving point since we more or less agree that the universe is still expanding in all directions, and there is nothing besides the universe, since we really don't have the concept of nothing, because there is no measurment for that, let's just say it is a big motherfucker, it has a without (kinda) that defies description as wholly as its within.  Hell---there is still ponderable matter that we can't ponder yet (think dark matter or whatever it is gonna be).

Isn't the centre of the universe the centre. Now you are all just confusing me on purpose. 




mnottertail -> RE: If you were a Science Teacher.... (7/8/2007 9:38:10 AM)

you can work with the center as fixed as a model in your mind as well as the fact that it may not be expanding equally in all directions, but in fits and starts, kinda like them electron microscopic blobs that pinch off and run end to end like a water balloon.

In any case, we are talking the universe and need not quibble about a few million light years of distance over a period of time...

I will gladly agree that it is for all intents and purposes fixed and some distance from us, who we know is on the outer edge of our spiraling galaxy




Raechard -> RE: If you were a Science Teacher.... (7/8/2007 9:41:53 AM)

Formula one needs to take into consideration the drift of the centre point from the earth or

...considering the differance between the size of the earth and the size of the universe the error is acceptable in the final analysis.




Raechard -> RE: If you were a Science Teacher.... (7/8/2007 9:43:53 AM)

I concur

I just love being an amatuer scientist.




mnottertail -> RE: If you were a Science Teacher.... (7/8/2007 10:11:21 AM)

Schlau, aber nicht wahr------ there are only so many significant digits of use.  Heisenberg has some implications here------

3.1416 is good enough for fitting metal parts, but hardly sufficient for electrons.  22/7  is probably too exact for what we can measure in the metaworld of the universe (not each ponderable object). but trust me, geometers do not calculate the weight of the world based  upon what has been left over for material when you shit, and what has been consumed and transformed.  That is Dr. Phil's job.

And you can quote me----

I'd try the best as i could however with the whole creationism vs big bang i'd be too focused on that. Anyone want a funny way of looking at it watch Lewis Black's Red White and screwed. I can't tell you how many 7 day creation people i had had clam up or say its the devil's work in relation to dinosaur fossils. Of course Anne Rice was nice enough to tie it all together with a pretty black ribbon in Mnemnock the Devil. Long and short of it Evolution did happen but god does exist and jump started the whole thing

Oh, darling-----is this our FIRST fight?

Dodd, D.M.B. (1989) "Reproductive isolation as a consequence of adaptive divergence in Drosophila pseudoobscura." Evolution 43:1308–1311 is a pretty clear example of Allopatric speciation by geographical isolation. Read the paper, you can do it too!


Haven't read it you will be surprised to hear but the clue is in the title. 
"reproductive isolation" "adaptive divergence"  ie still a fly with slightly different characteristics.
What is needed is a new species. ie something that is not a fly. 
Dont forget geneticists have bred counless thousands of generations of flies...and all they end up with is...more flies lol

Eager beavers that they are Darwinians define as a different species a sub group of a given species if that sub group cant mate with the main group.
How desperate is that when you consider all of the many millions of genuinely different species that have been and still are extant.

(hold arms out wide) It's THIS big.




popeye1250 -> RE: If you were a Science Teacher.... (7/8/2007 10:52:01 AM)

And no matter how big the Universe is wouldn't it have to "end" at some point?
And what would there be at the "end" of the Universe?
Some good answers in here thanks.




Raechard -> RE: If you were a Science Teacher.... (7/8/2007 10:55:36 AM)

At the end of the universe is the giant skirting board.

There in lies the quixotic answer to the universe, if you think of the ponderable part as a balloon being blown up, or as some envelope, there is no without, it is the void, indescribable, unmeasurable, with out form or function-----unmeasureable, since we have the tools of space and therefore the artifice of time and gravity, form and function to help us fathom, what is outside the universe is void, not zero, void, no quantum foam, no nothing---at least that is where we are now,  kinda like telling me what a highschool science teacher is without using any of those concepts or their near neigbors. (it defies
description, it is that big (and I say that as the buddha laughing)

LOL, at least that, but in the parlance here--------hard limit to what is without the void.  Said so much better than I, and he didn't even have to resort to the word cocksucker in describing it.





Raechard -> RE: If you were a Science Teacher.... (7/8/2007 11:14:45 AM)

The idea I’ve always liked is that space is a sheet of fabric and objects placed on the sheet of fabric cause a depression in the fabric and so other objects get drawn into them which is gravity; the bigger the object the bigger the depression and so the greater the pull of gravity. The fabric can also be folded many times with holes in the fabric leading to shortcuts to other parts of space.




Raechard -> RE: If you were a Science Teacher.... (7/8/2007 11:17:40 AM)

We only see a small part of space just like people before us only saw a small part of the earth and therefore thought it was flat.




mnottertail -> RE: If you were a Science Teacher.... (7/8/2007 11:18:23 AM)

This is coined Minkowski space by Al Einstein, in fact you see the Nova stuff or whatever and it is always shown as divisible grids, like a fish landing net.  Yup, that is the effect that we fathom, there is a fabric to the universe, which we pitifully describe as space-time.
