Astronomers and other researchers have been making a concerted effort to search the cosmos for alien intelligence for decades now. But what about putting on a porch light for any alien astronomers who might be performing the same search from the other side of the galaxy?


We spend tax dollars on dumber things, at least this has the potential for some fun.


A new study out of MIT proposes using a high-powered laser to send a signal into space that could stand out from the massive energy of our sun and basically announce "we're here!" to anyone who might happen to be looking.


Instead of fishing for contact with a life form we determine to have a low threat value, they're saying F it, throw a net and hope we catch something.


"If we were to successfully close a handshake and start to communicate, we could flash a message, at a data rate of about a few hundred bits per second, which would get there in just a few years," Clark said.


"One day we might receive a signal from a planet like this, but we should be wary of answering back," Hawking said in the 2016 CuriosityStream series Stephen Hawking's Favorite Places. "Meeting an advanced civilization could be like Native Americans encountering Columbus. That didn't turn out so well."

I'm all for it, whatever happens, it would be exciting.

Time to add some flavor to the furture.

I for one welcome our new alien overlords.
I’m sure they’re smarter than us, even though they treat us like cattle.

Respect your evolutionary elders!

It’s like a bug flashing something shiny at a bird flying overhead. We’re probably just going to end up as lunch.

I'm hoping for at least a month long battle.

Surely they'd try and minimize collateral damage to harvest resources....unless we're the resource.

But if they just blew up the whole planet, it would suck all the fun right out of it.

The nearst star is four light years away at minimum that would be a back in forth conversation of intervals of four years. From there on out the stars get further and further away.

That's sad considering aliens are already here. Sad noobs.

Certain forms of communication has already been established with the ET's...so why waste the money building a laser that could potentially be harmful to the airborne pilots that fly our military and commercial airlines?

Same problems with lasers as with any other kind of light. It's pretty pokey in the context of the entire universe. And as coherent as it may be when it shoots out of the gun, it's probably gonna dissipate and fade pretty quickly into the rest of the noise.

Chances would probably be much better using some other kind of massless or negative mass energy transfer. If such a thing is ever found to exist.

Otherwise... multi-dimensionality? If the aliens are sitting right next to us, the laser is shooting in the wrong direction.

Although in this scenario, it's more likely that we're the fish. One of the solutions to the Fermi Paradox is that in the universe jungle, the prey keeps quiet to avoid the predators.

It wouldn't be boring.

Maybe we should learn to communicate properly with each other first, or maybe even the different species on the planet.

Frb121102 blows out the background radiation when it swoops by.

It parts the red shifted CMB sea. Then boom! Big energy spike. Then gone.

We see it pretty well.

He may no longer be with us but does it makes his opinion any less scary

Stephen Hawking's Most Provocative Moments, From Evil Aliens to Black Hole Wagers


“Such advanced aliens would perhaps become nomads, looking to conquer and colonize whatever planets they could reach,” he said. “Who knows what the limits would be?” And in the 2016 documentary Stephen Hawking’s Favorite Places, Hawking reiterated his views: “Meeting an advanced civilization could be like Native Americans encountering Columbus. That didn’t turn out so well.”


I want to say turn that dam light on, but lets hope if its answered we dont suddenly ALL become homeless

Eight years minimum. Four years to get there, four years for their answer to get back to us, plus whatever time it takes for them to decide id they want to answer us and what they want to say.

You forgot the beuracratic 50 years it'll take us to decide what to say in the first place, then the 20 years it will take to decipher the inbound reply.

There is no real intention to find life. Nasa and Seit secret mandate is to prove to us how devoid of life there is in the cosmic void.

This is a great thread... I wish there were more like it being ATS and all. All there are is political threads, hopefully it dies down now that the midterms are over.

Anyway I hope if we do attract aliens then they bes be a nice kind that can help us out if there are mean ones.

Right. We think every lifeform in the cosmos is as technologically dull as we are. Mankind needs to develop ways to identify and communicate with the aliens that are visiting our Earth realm all the time. Even though they have no interest in us, they might respond with a "hello" somehow.

Hello to you too.

It may be wise to launch the signal(s) a reasonable distance from planet EA*RTH and watch the signal for responses.
Considering not all are peaceful or biologically compatible with this planet potentially who may not already have access to planet EA*RTH.
