Hummmmm, does this have any connection.

Will be something like this -----v

Man doesn't have the technology or capacity to detect signals 3 billion light years away, and nothing anyone can say will ever convince me otherwise.

Yes I do...built the SOB in my garage one rainy weekend. Been detecting light every since.

Its light from 3 billions years ago that has just reached earth. Not hard to detect when it has come to your doorstep. Every time you look up at night you are seeing the the sky as it was thousands and thousands of years ago. Looks nothing like that anymore in reality... many of the stars you see are not even alive anymore but just has millions of years of light still left coming this way before we physically see that they have died.

Rednecks seriously discussing high tech technology, the FEDS and what they are up to, MARS and "light years....

It just doesn't get any better..

I'd put us up against some city slicken Berkley College grads any day.

I know that's right. Especially since "SOME" of us are right most of the time...

You ain't kiddin!! Only Google has a chance .
We've got rocket scientists, to famous detectives, and everything in between. Hell, we've got a Webster Troy!!

This was the only conspiracy that actually made my skin crawl. Glad we made it thru that 36 hour window.

Any dead bodies pop up in this deal yet?

I understand the concept, what I don't buy is the idea that we can measure a figure like 3 BILLION LIGHT YEARS....and get within any kind of reasonable accuracy. I mean how could you ever confirm/verify something like that? I've no doubt that we can detect any number of weird anomalies in any number of different ways, but how do you verify the source/distance of anything like that with any real accuracy.

Whatever technology we have to do that...I don't feel, can really accurately be "calibrated", for lack of a better term.

Short answer, astrophysics. Longer answer: https://en.wikipedia.org/wiki/Cosmic_distance_ladder

The method science has of "calibration" as you put it is through conducting experiments and noting how the results compare to expected outcomes. Designing meaningful experiments for any one of the hard sciences is a field unto itself...and I just so happen to work as one of the engineers who designs space instrumentation electronics that conducts these kinds of experiments. You are correct, scientific measurements are not perfect but we know enough now to ensure that they are pretty darn precise...and the level of scientific scrutiny these kinds of results go through prior to publishing is pretty mind boggling.

Galileo's method was to hang a thin rope in his line of sight to the star and measure the maximum distance from which it would wholly obscure the star. From his measurements of this distance and of the width of the rope, he could calculate the angle subtended by the star at his viewing point

Galileo was doing a lot back in the 1500s, I cant imagine how much we have gone from there.

Ah, the ole "I don't understand it, therefore it must be impossible"

Thanks for your reply....but 3 billion light years?

Thats a figure I can't get my head around, given the "size" of a light year...and the size of a billion of those...

I'm allowed 1 conspiracy theory, aren't I?
