Flickering Stars: Could Aliens Be Sending Us Signals?

[dropcap]W[/dropcap]hen scientists go out looking for research funding, it helps if their projects aren’t all that exciting. Excitement usually goes with the most speculative, cutting-edge science, but funding agencies usually prefer to put their money on projects that seem likely to bear fruit. “You pretty much have to demonstrate that you’ve already done half the work to demonstrate it’s feasible,” says Lucianne Walkowicz, a postdoctoral fellow in astrophysics based at Princeton University.

By that standard, Walkowicz’s latest project shouldn’t be getting any funding at all. She wants to conduct a search for extraterrestrial intelligence (SETI), not by doing anything so conventional as listening for radio transmissions á la Jodie Foster in Contact, or watching for flashes of laser light. Instead, she wants to see if ET’s are somehow manipulating the light coming from their stars so that they wink at us — a long shot if ever there was one, especially since she has no clue how they might go about it.

But thanks to a program titled “New Frontiers in Astronomy and Cosmology,” funded by the John Templeton foundation and administered by the University of Chicago, Walkowicz is getting her chance. Cutting-edge research is what this program is all about, and the question “Are We Alone in the Universe?” is one of the major areas it aims to address.

The odds of a discovery with Walkowicz’s project may be long, but the search technique is quite straightforward. “Our premise,” she says, “is that up until now, we’ve had a preconceived idea of what a SETI signal would look like.” It would basically be the sort of signal we know how to create, and understandably so, since searching for a signal from some entirely unknown technology would be kind of difficult.

If aliens were so advanced that they could cause their star to appear to flicker, however, it wouldn’t matter how they did it, and it would be easy enough to see with existing <a class=”StrictlyAutoTagAnchor” href=”http://www.etupdates.com/tag/technology” title=”View all articles about technology here” >technology.
