None strong enough, not until Nazi Germany started broadcasting more powerful signals, if I am not mistaken.
Ours would be weak and quite attenuated by then. Really fuzzy and hard to pick apart from background noise
Let's be honest, this signal is basically a PBS broadcast warning that 95 light years away is a very primitive planet, and to avoid it at all costs. Instead, take the IG-70 off ramp, rimworldly.
Awesome! So the first thing they are going to find out about us in about 15 years is from propaganda in Nazi Germany. Great first impression.
Now it looks to be of terrestrial origin. Why you don't talk about this crap until you have more proof.
I think in their defense, they tried to keep it internal, until some outside party found it and decided it was being secreted away.
And let's be honest, cosmology has to, and does, leave a lotta wiggle room for creative semi-educated spitballing. Proof isn't really a requirement.
Extraordinary claims always should be met with demands for extraordinary evidence. I need peer review and replication
Pretty much the only scene I remember from Contact was the aliens sending the transition back to us and everyone freaking out.
