You know, we’ve made attempts to contact alien civilizations. Of course, given the vast distances involved, they could hardly have succeeded yet, even if there are intelligences out there to receive them.
I wonder, though, do our scientists believe that these intelligences will be friendly. The known history of advanced civilizations contacting primitive ones has not been happy for the primitive ones.
The quarantine barrier is imposed from without ... look all you want, but you can only see what light and other signals are approved to pass through the the quarantine barrier. Maybe in a few centuries things will change ... meanwhile, hang by your thumbs and write if you get work.
In fact, that's what I like about their idea.
The eventual 'shotgun' pattern developed by the laser beam over great distances and the sensitivity of their new equipment in detecting 'lased' light.
In some ways distance, to a certain point, is a help with this method.
