Here's an absorbing question for you. If LIGO could aim its lasers straight up, in the night sky, how bright and what color would they be?
Well the input laser strength is 10W, not much, but it's wavelength is 1064nm. That's in the infrared. The human eye is quoted as seeing as around 400nm to 700nm, as low as 380 for werewolves and maybe 780 for vampires :-) ( with peak sensistivity at 555nm )
Alas, we wouldnt see it!
Cheers, Mike.

Well, you're right on several levels, but I think it was a trick question. Pointing straight up, you definitely wouldn't see them because they're coherent light, and without something to diffuse the light or be reflected off of, you won't see anything. (Think of a laser pointer. You don't see the beam in clear air, only the point when it impacts the wall/screen/cat/whatever.)

I am so slow sometimes ...... you know I think we could save the US taxpayer alot of money here!
We could just set up a row of deckchairs alongside the LIGO's. Equal numbers along each arm for greater sensitivity. Oh, and that would be deckchairs with cupholders. Tell the scientists to go home for the weekend. Get a volunteer group to watch the lasers. Of course you'd have to supply them with beer and pizza. Now if, after a while, enough of them think that a gravity wave has passed by - then we'll call it a detection!
Any volunteers to form a quorum? :-)
Cheers, Mike.

Some time ago, I started another Team Recruiting Thread on CPDN, since I saw that there wasn't one. It's been quite well received. Now, because some moderator says the 73 posts of the thread take too long to download on his ADSL, he's unilaterally re-spawned the thread, with none of the original wording of purpose or whatnot.
Suffice it to say, I flipped out so hard on him I suspect my account is toast. Good riddance, in which case.

It probably would have been nice if people had been given 24hrs to adjust to the change over before posts were deleted.

Hi everyone, is there room

Hi everyone, is there room for one more soul seeking asylum from CAFE TROLLHAVEN?
This looks like such a nice place.
I,ve been exploring the science here for the last few days And have been surprised at how interesting it is.
It,s ironic that someone being nasty over there showed us where you all had gone!
I had no idea where everyone had dissapeared too. LOL
RE: Hi everyone, is there

Welcome, take a seat, and shoot the breeze! :-)
The science is very absorbing!
Cheers, Mike.
