In case anybody might have the time and interest... ;-)

NASA's Kepler mission has confirmed the first near-Earth-size planet in the “habitable zone” around a sun-like star. - -

The Kepler-452 system is located 1,400 light-years away in the constellation Cygnus.

1400 light years, we would need some kind of StarGate to get there in a hurry !

Very true. Just if you happen to get even any hint of such a thing available, please notify me, too. ;-)

This is also being discussed over in the other science thread.

Lets focus on this putative planet and see if they sent us any kind of message 1400 years ago.

Would surely be interesting, but dunno, whether the Arecibo radio telescope is able to cover the correct direction or not. If it is, then I suppose some of our WUs already may serve the purpose.

Well dunno what is the usual speed of radio transmissions in the UK, but generally...

Radio waves are a type of electromagnetic radiation, and like all other electromagnetic waves, they travel at the speed of light. But it also depends upon frequencies and wavelengths. It is much more likely that laser signals would be used. See this link.

That's an interesting concept. How could they not send it at light speed. So far as we know information cannot travel at faster than light speed. Even if they used semaphore flags if we were to spy them from Earth it would have been a message crafted 1400 years ago.

As I said; a good question. How do you send a message from this distant planet at speeds slower than the speed of light ?

The computer composing and posting the message may operate at other than what you would consider the speed of light. But once it was broadcast or written on a billboard it would travel to eyes, ears and receivers on Earth at the speed of light.

Maybe the idea was, that they put a letter in their nearest local Royal Mail pillar box 1400 years ago?

There is a precedent. I hear that the Chinese Postal Service is proud of the fact, that it has carried mail for 6000 years, without anything ever getting permanently lost. ;-)

And this makes one wonder, why nobody has checked the Tycho crater on the Moon. I gather, that Surveyor 7 was closest of all Luna, Surveyor and Apollo landings there, but even that was about 29 miles north of the rim of Tycho. ;-)

In your infinite wisdom, why don't you ask somebody to read and explain to you the last three messages in this thread and their references plus meanings?

In the meantime, for us others, let us recall that the mentioned Tycho crater TMA-1 actually was #2 in a sequence of 3... ;-)

"2001 A Space Odyssey" was simply an entertaining science fiction film that centred around a black monolith found in the moons Tycho crater, known as Tycho Magnetic Anomaly One (TMA-1). There would be no reason why NASA would go there for real.

I know it's your name, but no need to be so snarky!

Because NASA knows the difference between science fiction and scientific fact. Other than having a vivid imagination A.C. Clarke had no inside information regarding an artifact on the moon or elsewhere. Some of today's youth have grown up believing in space fairy tales.

"The Sentinel" is a short story written by Arthur C. Clarke in 1948 and first published in 1951, which was used as a starting point for the novel and movie 2001: A Space Odyssey in 1968. Man didn't set foot on the moon until a year later.

Do you have a source for this claim? Or a lot of experience with today's youth? Or is that just an opinion based on your perception? :-)
We have nothing to fear but fear itself. Apart from pain. And maybe humiliation. And obviously death. And failure. But apart from fear, pain and humiliation, failure and the unknown and death - we have nothing to fear. Who’s with me?
