    The other problem is the ship signal they traced would have been frequency shifted by the same amount as the time dilation. They would have had to compensate for that to even detect the signal.

    It was 1 hour : 7 years I think. So about a factor of 60,000. So if a ping was once a second it would be once every 42 days. And if it was a 1MHz transmission it would be at about 17Hz.

    So they somehow realized the once a second 1MHz signal was now a every 42 day 17Hz signal at 1/60000 the power. But didn’t realize that there was time dilation involved.

      They knew there would be time dilation. They literally discussed it just before they went down there. They just thought they could get it done in a few earth-years rather than decades.

      They did know about the time dilation, though? They weren’t surprised by the fact that there was time dilation, they just didn’t fully grasp what the results would be.
