Very interesting point that extraterrestrials may not be emitting anything we can detect, either. Oh well.
Anybody that might be listening would know why the earth is beginning to become quiet.
However, its probably best if we don’t attract any attention. Better to get a covert look at them first. Hopefully they’re dumb, edible, and slow.
NOBODY with the brains and talent to need to communicate across cosmic distances would do so with radio waves or any other sort of electromagnetic radiation. That would be like me trying to get messages to Germany by splashing stones in Baltimore harbor and hoping the Germans could read the message on the ripple waves when they got there. The whole premise of SETI is idiotic and a colossal waste of money.
Maybe Viagra and they'll SEE All Us!
WOOF!
It doesn’t really make any sense that they would be using radio. Space is radio signal noisy.
I always had the vision of us scanning the horizon with binoculars looking for smoke signals while the aliens are transmitting digital radio.
Expect a visit soon.
Aliens are just now reciving Dick Clark’s Bandstand show.
They would detect us the same way we would detect them - by noting our oxygen rich atmosphere.
You're hoping that the aliens are Shmoo?
The Star Trek universe had a race of beings on a planet orbiting Alpha Centauri, which was roughly at the same technological stage we are, except that at some point, they developed a paranoid streak, so all their communication and entertainment was through landline, and most of their civilization was underground, thus explaining why we never saw or heard of them. Except for the underground thing, we’re pretty close to that as well. A lot of the news and entertainment we consume these days travels across the internet instead of the air, and what little we still push through the air is of such low wattage that it may not be making it past the ionosphere.
Communications to and from the moon during the Apollo missions was very effectively conducted on not much more than 1/4 of a watt.
Of course, there wasn't anyone else using that frequency at the time. But still....
BS. Old-style transmissions are undetectable after a few light-years anyway. The nearest star is 4 light years away.
(What is stronger? the signal or the background noise?)
Well.......okay, then.
