Definitely not. To use a spectrograph the object must either be emitting light, or reflecting light. Any form of dark matter would not or we'd have seen it.

I thought it would have to be hot like a star and emitting photons.  Maybe I'm getting it confused with a spectrometer.

[trostol]

lol is he now taking credit for social media?

[SciFiAuthor]

Wouldn't aliens already be able to detect it from earth or does shooting it at the sun amplify the ability to detect it?

Do you want to broadcast to advanced intelligences across the universe there's a weird angry species on this bright blue ball and take the 50/50 chance they don't liquidate us for fun?

If they had a sufficiently sensitive spectrograph aliens would detect all sorts of unnatural signatures if they turned their spectrograph towards Earth. We're lit up like a Christmas tree, so to speak. The problem is that we haven't been lit up for very long, the earliest indicators that show there is a civilization here only go back about 150 years. So civilizations within 150 light years might know we are here, but further out, they don't know yet.

The biggest problem is heat. Advanced civilizations will produce MASSIVE amounts of infrared light. It can't be avoided. We're not very hot here on earth, so likely we wouldn't be considered a threat until we produced massive amounts of heat. That means massive amounts of energy, and that might constitute a threat to an alien society.

Please tell me one of you archived the Sterling Allan episode so it isn't erased from existence. Too horrific to be forgiven.

[Dixon Bawls]

Take a drink every time Rich says "guess what?"

It just needs to either emit light or reflect light. Dark Matter in any form would not or it would be visible, it would no longer be dark.

what was the date on that one 

[Sean92008]

Richard's schematics for nuking the sun: 

LOL, really.

[Royal_Tenenbaum]

More Uranal jokes, please.

Uranus is right next to the outer rim.

[SaucyRossy]

Hahahaha

[Sean92008]

lost TuneIn for 20 seconds

[Royal_Tenenbaum]

what was the date on that one 

July 29 according to twitter.

[trostol]

lol i knew he was gonna take offense to that pocket protector thing

[SaucyRossy]

"We're talking people wearing pocket protectors"

RCH response "WE ALL WORE POCKET PROTECTORS"

[Royal_Tenenbaum]

That is Generations Richard. It's a movie not an episode. It is also shit.

[LadyFish]

Was he saying NASA didn't the sci-fi movie protocol when landing on Mars?

[trostol]

generations wasnt bad..problem is most of the NG movies just were..meh

[SaucyRossy]

This guest is a lot of fun, Richard is actually laughing out loud at some things he says and then the next moment it's a shocking reveal like a government detail following community college astronomy professors.

[PB the Deplorable]

Haha this guest out-filibusters Hoagie.

Hoaxie managed to find an egotistical crackpot on the same level he is, amazing.  Ugh

Man, that is all really fascinating.

One of my favorite stories along those lines was an episode of the old TV show Pete & Pete. In the show aliens had discovered earth through TV signals so an alien kid showed up in this little town who was obsessed with Johnny Unitas and I Love Lucy because those television signals had just reached his planet.

I don't think contact will be question, the only question now is how and when.

any aliens that visint me/us i want to look like  Sally Solomon

I think the Next Gen movies were all let downs. The show was so good. I agree with RLM's 2 Picard's theory. http://redlettermedia.com/plinkett/star-trek/star-trek-generations/

Would our heat "signature" increase if cold fusion works and allows for nearly unlimited power use?

Had to Google... would agree.

GEOMETRY IN THE DATA! UREEEEKA!

will take a look at it...indeed TNG was great as a show..as was most of DS9...the rest i am iffy on..i wish we had a new series

[Sean92008]

Or Lt Yar.  Actually, those Betazoid chicks are hot.
