<p><pre><code>    &gt; Jason Wright, an astronomer from Penn State University, is set to publish an 
    &gt; alternative interpretation of the light pattern. SETI researchers have long
    &gt; suggested that we might be able to detect distant extraterrestrial 
    &gt; civilizations, by looking for enormous technological artifacts orbiting 
    &gt; other stars. Wright and his co-authors say the unusual star’s light pattern 
    &gt; is consistent with a “swarm of megastructures,” perhaps stellar-light 
    &gt; collectors, technology designed to catch energy from the star.

I guess the theory is that an advanced civilization would be building particle accelerators on the scale of solar systems, or maybe constructing wormholes?
