E.T. a machine

The Galaxy yes, the universe no. Other life forms don't have to be from our galaxy.

Besides, why do you think that an alien species would use radio signals as we do. Maybe the communicate through light or something we've never heard of. If you travel for light years radio communication (that only travels at the speed of light) would be extremely ineffective. You need something faster than light to stay in touch with your home world.

I just assume that at some point in their history they would have used radio communications. You have to start somewhere.

And of course, who knows with extragalactic lifeforms. I doubt we'll find any evidence of their existence or non-existence anytime soon.

Their radio transmissions may well have reached us when we were banging rocks together for communication and now they're using something bigger and better. I mean, it's a big timeframe we've got to deal with, not to mention a big universe. After all, you say the galaxy is only 100,000 light years across...and radio waves travel at the speed of light (or thereabout), that means that it'd take 100,000 years to get here from the other side of the galaxy. So, it's still a big ballpark.
