even more disturbing is the fact that if they were so advanced and had evolved past fighting each other, wouldn't they be wary of other civilizations - why would they broadcast their presence?

Another thing to think about is, "they" probably never even considered Radio Waves or any type of communication we've achieved. So they would have no way of even conceiving how our methods of technology is powered, likewise with us trying to decode an alien signal.

Nice to see they aren't wasting any time on this, but 1,500 light years away?
I also read an article recently where a scientist claimed that any radio signals could be encrypted and not picked up by the equipment we are currently using.
Edit- I see this has already been questioned.

Why wouldn't aliens use radio waves? Sure they would have other tech, but they possibly still use radio too. Perhaps they are able to use radio waves in ways that we don't know about yet.

Perhaps it's an ancient civilization that long ago reached Technological Singularity and it's just artificially intelligent robots building bigger and more intelligent robots and what we see are giant superstructures as part of a natural AI progression. The biological life may be long gone. Is that not, theoretically, where we are headed ourselves? Imagine if left alone for thousands of years to continuously outdo itself. Hmmm.....
That's possible. On the other hand, wouldn't it be better to keep evolving smaller instead of larger? Nano-technology would need far fewer resources to itself. Depending on hos small they got, they could probably pull particles out of the air & use them directly as fuel or building blocks.
Just my 2 cents
True for certain aspects of technology, but not if it's a Dyson Sphere- it would have to be larger than the planet from which it's capturing power.
A Dyson sphere is a hypothetical megastructure that completely encompasses a star and hence captures most or all of its power output.
