Supposedly, according to Einstein or somebody, the universe is curved, right? Any electromagnetic radiation emitted from Earth will eventially boomerang and return from whence is started, much attenuated of course.

In the future, would it be theoretically possible (not necessarily feasible), with a super-sensitive radio apparatus, to pick up the original news broadcasts of the attack on Pearl Harbor?

My answer is probably No, but I can't say why. More than once, I've given away 1930s radios, and the recipient asks, in jest, "Can I pick up Pearl Harbor on this thing?"

Additional info:

The futuristic radio would be super-sensitive, but also super-selective. Of course, to receive Pearl Harbor announcements, we would temporarily suspend all broadcasts from Earth than might interfere with our reception.

You would also have to something about noise. Due to the square law (twice as far from a reference, one fourth the singal, light, noise, whatever. three times, one ninth, etc) You might pick up the signal, but it would be buried under wo much noise (more today than 1941, I'll bet). I think the right thing to say would be "It might have, but it can't now."

Lewis, I'm going to remember that line -- I might need it in the future!

Well this is interesting... I've always contemplated this concept with variations for years.
I think you could hear it or tune it in.
Yes.. of course why not?

If a signal is broadcast from NY and it hits my antenna first here in NJ and a little later in CA and later in Japan... it doesn't disappear... right?.. it keeps going..
NASA sends radio signals to control martian rovers that takes months to get there... so ... sure.. I feel we could tune it in if we had a sensitive enough receiver.

Just like audio. When Lincoln gave his Gettysburg address... the people in the front of the crowd heard him first and the people way way far in the back heard him too but just a bit less volume and a tad later... right?... so those words didn't just stop at the last person in the last row... there was a farmer over the hill.. and a frog in the grass further away that heard it too and a bird ... and so on... and in fact ... I today am just standing a lot further away.. and IF my ears were sensitive enough I technically ought to be able pick up that whole speech... if I could somehow isolate and hone in on it... right?

Sorry about thre multiple postings (something to do with a time delay or maybe a brain fart) but several years ago, I don"t recall just how many, I read an article(Readers Digest?) about some people in England receiving TV test patterns from a TV station in Texas (Or maybe it was the other way around) which of course was pretty remarkable. What was even more remarkable was that the Texas TV station no longer existed and had been off the air for several years at the time the pictures were being received in England. Am I really reading and writing ths tonight or did I do it in 1954?
