CAMBRIDGE, Mass. — Attracting aliens might be as easy as leaving a really, really big light on.
A new study from MIT suggests that the light from a laser could spark the interest from aliens if they exist.
The study's author, James Clark, says while that is difficult, it's not impossible. He says the lasers have already been invented, they just need a telescope that is big enough.
The powerful laser would be focused through a telescope aimed toward space.
