Have astronomers discovered an alien megastructure?

There's also the matter of 1,500 light years, which means that if they're a thousand years ahead of us we won't out know about it for 500 more years.  Think about it, we have less than 200 years since we first began broadcasting,  they won't hear us for another 1,400 years or so.  But if they're building structures that can block 20% of a stars output, they have to be using "free energy". we have just started with quantum mechanics so I'll guess that in another 1,500 years, if we survive, we'll probably doing that too.
