I bet you know all this but 4 light years sounds near but 1 light year is 6, trillion miles, light travels at 186 thousand miles per second so it’s going to take over 4 thousand years for a rocket to arrive and 4 thousand years to come home.The nearest star is only 4 light years away.
Radio and tv transmissions travel at the speed of light.
So far from not receiving any transmissions they’ll have watched all City’s success up to 2019.
There are over 10,000 stars within 100 light years never mind 200. They will have been receiving radio signals for 100 years and will shortly start receiving tv signals.
BrilliantIf anyone intelligent from another planet has visited Earth, they certainly aren't in the USA.
As an Aussie, you really should've kept a low profile when intelligent life is being discussed. ;-)The clever twats at NASA would disagree
The amount of meat you gobble I ain't going to argue mate.I doubt with the whole planet and indeed galaxy to choose from, they'd eat us, most carnivorous and omnivorous species taste terrible to meat-eaters.

I do. I was correcting the poster who said erroneously that no terrestrial signals will have got anywhere near a star yet.I bet you know all this but 4 light years sounds near but 1 light year is 6, trillion miles, light travels at 186 thousand miles per second so it’s going to take over 4 thousand years for a rocket to arrive and 4 thousand years to come home.
The maths are insane because any civilisation may have died out long before we get there, we have to come up with new laws of Physics before we can travel anywhere.
That’s what professors of Quantum Physics work on and why they don’t rule out Aliens travelling the universe if they are millions of years in advance of us.
Radio / TV signals they have to point at the right star and people need to be listening
