[1) A supernova is observed. Scientists say the original event occurred 4000 years ago using various techniques. You'd accept that.
2) A supernova is observed. Scientists say it occurred 100,000 years ago using the same techniques. You'd reject that.]
I reject #2 as science as it is unobservable. In order to study something in science one must observe the associated event.

That would depend, of course, on how far away the star was that went nova. Light, travelling at 186,000 miles per second, can take many millenia to reach Earth. Looking at the night sky is actually looking into the past, since the light we see from the stars each night...
Fuck it, wasted verbiage.
Em... unless you were alive 4000 years ago to see #1 happen, each are equally unobservable, which is where science's methods of observation and ability to draw reasonable conclusions kicks in.
So either you reject both theories (and, if you're unable to give a scientifically valid reason or concern, prove your fundie-ness), or you take both as fact. Which shall it be?
But #2 is observable in just the same way #1 is.
To clear this up: supernovas of a star that's 4000 light years away would not be observed for another 4000 years, since it would take the light from that event 4000 years to get here. The only supernova we could observe on earth as it happens is that of our own sun, and by the time we saw it, we'd all be dead.
Duh Mickey - If it exploded a billion, billion kilometres away 100,000 years ago we are observing 'the associated event' right now!
ez-c Isn't Alpha Centauri only 4 light years away? (oh and our sun's too small to do that, but it will turn into a red giant in 5 billion years os so)
The speed of light is 186,282 miles per second, to be within the nearest mile per second.
Sorry Mickey, but if you accept #1, you must accept #2.
Julian - Note where ez-c said "as it happens". ;-) We wouldn't see Alpha Centauri nova until four years and change after it happened.
For that matter, our own sun is about eight light-minutes away, so we couldn't even see it go until eight minutes after the fact.
SN1987 was observed. We saw the supernova happen. Then we saw the light spread out from it and light up the surrounding dust. We watched as the various nuclear products decayed and gave off their characteristic light colors right on schedule. Then the Hubble telescope measured the distance from the lighted dust to the supernova. Using high school trigonometry, we computed its distance as 169,000 light years away.
Biblical creationists have tried to explain it with changes in the speed of light or "space warps" (argumentum ad Star-Trekum), but have never worked out the math to show how these things, even if true, would have gotten the results they're looking for. They seem to have no problem with inventing stuff whole-cloth without observation or even much thinking when they need to.

One of them has actually been pretty clever at this. He produced a compression factor for space that is 0 on Earth and increases farther away. This describes a universe with a radius of about 15 light years, having objects in it correspondingly smaller, thus distant galaxies look small because they are small. The speed of light is slower in compressed space and becomes faster as it gets closer to Earth.
Twas me that made the original comments. What amused me the most about this was that I clearly said, "A supernova is observed," only for mickey to tell me that apparently such things are *unobservable*, lol! I'm sure those photos of SN1987A must have been faked then ;)
"In order to study something in science one must observe the associated event."
They...are (?). That's what "a supernova is observed" means. The light from the supernova just takes time to get to us, so...
“I reject #2 as science as it is unobservable.”
It’s the same 0bservations as number one, idiot.
“In order to study something in science one must observe the associated event.”
No. That would make every CSI episode one where the techs cannot solve a murder unless they witnessed it.
In science, repeatable observations are key, but they are NOT ‘eyewitness testimony.’ We can build up a database of observations that anyone can make, and the accumulated facts point to our conclusion.
It’s very much science.
Confused?
So were we! You can find all of this, and more, on Fundies Say the Darndest Things!
