Study examines best way for aliens to contact Earth

TORONTO - Two astrophysicists from McMaster University want the search for alien life to focus on where E.T. would try to call us if he could.
Rene Heller and Ralph Pudritz’s paper, The Search for Extraterrestrial Life in Earth’s Solar Transit Zone (external - login to view), is quickly making global headlines.
They suggest we look at what potential outsiders can see about Earth from outer space, and then use that to search for them.
The Toronto Sun caught up with Pudritz for a phone conversation from Germany on Thursday:
Q: What exactly are you and Heller proposing?
Pudritz: “It all starts with the idea and the question of how do we find (extraterrestrial life)? People have been very successful hunting for planets around other stars. The most successful way we have of doing that is ... if a planet moves across the disk of a star, the light from that star will drop by a very small amount because it’s being blocked by the planet. That’s called a transit.
Now if you imagine ... seeing the Earth transiting, then the question is what observers in the galaxy would be able to see ... They won’t know there’s people on it of course, but they’ll know it’s habitable.”
Q: What do you suggest we do within Earth’s transit zone?
Pudritz: “By doing this calculation for the type of technology we have now, we estimate that there would be about 10,000 to 100,000 interesting target stars in this transit zone that could be looked at. That would take in itself an enormous amount of telescope time using our current technology. So this is a very ambitious project. It’s a rich area to examine that has not been looked at by any systematic survey. That’s what we’re saying: Look there, use current technology.”
Q: Is it possible we’re missing signals as we speak?
Pudritz: “It’s not even obvious, it’s not even clear that a civilization would necessarily want to transmit. There’s so many factors that we just do not know: How such civilizations would work, if they would transmit, etc. These are all questions we have absolutely no knowledge of and so in our paper, we just try to stay clear of those questions as there’s no way of really answering them.”
Q: Do you often wonder about possible forms of intelligent life out there?
Pudritz: “It’s a very human question. It’s maybe the ultimate question ... There’s two parts to it — is there life in the universe and is there intelligent life in the universe?
The very simple microbes? It would be very surprising if they didn’t show up because we’re learning more and more about them. But intelligence? That’s a million-dollar question.”

The chance that aliens, long, long ago decided to contact Earth specifically (Why?) are zero, zilch, nada. Even a relatively close star would have sent their signal when we were still knapping flint and no one would bother transmitting to primitives. Maybe, we intercept a signal from a civilization from the past. Maybe we send something back that gets there long after our civilization is gone. The relativistic problems that prevent us from distant space travel also prevent two way communication. We had either better get used to the idea that we are effectively alone (even if we do intercept a signal) or hope that Einstein was dead wrong (and he still ain't yet, a century on).

How would aliens on another planet so far away even know that we (aliens to them, of course) were so primitive?

Precisely. The title of the thread is absurd. Nobody is trying to specifically communicate with us.

How do you know they are communicating with us specifically? They could just be sending messages out hoping that someone, somewhere, will receive them. They could be sending messages out in lots of different directions at random hoping for some to be received, and some of those messages could just happen to reach Earth.

They don't know. They are not. If we hear anything, it will be random, at best. Aliens are not going to contact Earth, full stop. If they did send out signals to "whoever is out there", they did it long, long ago with no possibility of a response.

How do you know there aren't aliens living around 50 light years away whose signals would take only 50 years to get to Earth? We could easily receive those messages and then send some back and it'll only take 50 years for our messages to reach them, providing we make our signals strong enough to get to their planet.

Carl Sagan sent this message to 'the aliens', the return is included and I like the fact theu have big brains and a small body compared to us having a large body and a small brain.

Some folks believe aliens have been communicating with us for centuries...........we just haven't figured out what they are tying to tell us.

You don't understand that?

How embarrassing for you.

Well...........if I had to take a wild guess...........it might be the logo for one of their sports teams.



On the other-hand, this one is clearly telling me I should grow some dope.

Yeah, okay. I bet that they look like garden gnomes, too.

I don't know why the hell they'd want to contact us. Maybe ask us how to make good Mexican food?

Aliens should, for their own happiness, just stay way far away from this planet.

Otherwise, our negativity is liable to just bring them down and cause all kinds of grief they likely don't need.

STAY AWAY. SAVE YOURSELVES!!!!

The best way for aliens to contact earth would be banks.

How in fuk would any of you know when you had been contacted. I'm pretty sure you've all been dabbled with by aliens.

Oh that's easy. They say get your s hit together before you come lookin for us.

I had one as a bipolar, multisexual, self slaking alien lover. Who put the bot in the bot she bot?

It was a hoot watching him/her change from Conservative wild thing to quasi-religious Liberal self flaggellator and finally into hot Newish Democratical sexual labour enforcer!

The whip knows no politics, human! Your buttocks will melt as I flog your nether regions and wrap you in leather! Feel the sweet, sweet kiss of the lash and stand in awe of an alien sunset!

It was sort of a 'Lady Chatterly's Alien Lover' thing.

Crop circles are one of the things which make me proud to be British, along with the Queen, Churchill, Only Fools and Horses, Blackadder, the red telephone box, Big Ben, fish and chips, the mini skirt, PG Tips, the Spitfire and the Aston Martin CX75.

Is that the kind of book you would wish your wife or servants to read?

There is no "best" way to this situation at the moment.


If they made contact with us in any fashion, the majority of humans would try to kill them, because of fear or whatever.... Id try and kill them too, to be honest and im not sure why. A lot of people reading this would try also.


The best way for aliens to contact Earth is to wait another 100 years at the minimum.

Maybe, their first contact procedure is to log on to an internet forum as a new user.

If they're booted off as spammers, they move on in search of intelligent life.
