If there was a civilisation on a planet like earth in the galaxy of Andromeda, could we telecommunicate?

Question

With the level of intelligence and technology there is today, could NASA type radio systems be able to communicate to life in another galaxy. What would be the fastest method of doing this?

Or would it be like a "message in a bottle" in the vastness of Space?

Answer 1

Andromeda is too far away for us to communicate with.

What does 2.5 million light years mean?

If we sent 'Hi! What is life like over there in Andromeda?' and they answered 'Hey! How are you? It is getting warmer here with less rain. What's up with you?'... Their answer would arrive at our receiving station over 5 million years later. I don't think we want to wait so long!

;-D Let's talk to our astronauts on Mars first, OK?

Answer 2

We could, but chances are either our civilization or theirs will burn out by the time messages could reach each other. But you have to ask yourself a question, assuming that we could communicate with each other in "real time". Why would you give our location away to a civilization that is most likely more advanced than us? It has all types of implications. Say that they are slightly less advanced than us, say 60 years behind. They would have just recently discovered the varied function of radio communication, basic basement-sized computers which would have done very little to help their search, no space travel, and 1940's level science. No threat in that, but chances are, no communication.

Let's say that they have a similar technological level to ours (very slim chance of this). They would be able to do everything that we can, and communication would be a very safe thing to do. But more likely than not, they would be hundreds, thousands, or even millions of years ahead of us, and there's no telling what kind of technologies they would have developed, capabilities they would have, etc. If they were anything like us, the discovery of a new land would spark economic and political interest, and they might seek our planet, for any number of different reasons.

I think communicating with another, likely more advanced species is risky at best.

Answer 3

Andromeda Galaxy is about 2 million light years away. The fastest known electromagnetic energy is light, which travel one light year in a year (hence the term "light year"). So even if we could beam some kind of message with complete accuracy to a star in the Andromeda Galaxy it would take 2 million years to get there, then another 2 million years for an answer back (if they received our signal and decided to answer).
Is it possible? Yes.
Is it feasible? No.

Answer 4

Well, this question would imply some sort of a two way radio. Maxwell designed how it would work, Marconi showed that long distance communication possible and since then different people have contributed to the transmission. In the huge range of possible ways to transmit and receive data, the other side would need some sort of mobile phone or whatever and would need to speak the same language to make ledgible communication. Go back and watch another episode of Star Gate.

Answer 5

It would only take 4.4 million years to get a reply from any message we sent to Andromeda, at the speed of light. That would seem to suggest as little small talk as possible, nothing in the way of "Hi, how are you?". A better question would be "What is the meaning of life, the universe, and everything?". If they know the answer, It might actually be quicker than building a supercomputer to figure it out ourselves.

Answer 6

the probabilities that we are able to even discover the collision with andromeda are very slender. it rather is now no longer even a collision, which you would be able to communicate. Galaxies are in particular empty section -- no longer something is going to "hit" some thing. Odds are our image voltaic technique would be thrown spectacular right into a wildly eccentric orbit for awhile, and probable we are able to outlive. or maybe we are able to be ejected from the galaxy completely: ah, peace at very final. we are able to watch the milkdromeda chaos from a distance. even nonetheless to extra on the instant answer your question: I doubt we'd ever build a colossal "deliver" to take all of civilization a techniques from earth. extra probably we are able to colonize diverse planets interior the sunlight equipment, and then just about quite extra a techniques-off planets, so we are extra spread out and characteristic a extra ideal threat of surviving as a species. that is doubtful that we are going to ever flow away the galaxy autonomous of a parent action picture star and be useful to outlive. the situation might the full energy fundamental to help and finished planet's worth of persons come from?

Answer 7

Since Andromeda is 2.2 Million light years from here, NO.
Not only would a signal take 2.2 Million years to get there, but we don't have the power for such a signal.
The furthest we can send a signal right now, with the Arecibo radio telescope is about 40,000 light years.

Answer 8

The Andromeda Galaxy is about 2.2 million light years away. That means that a radio message would take 2.2 million years to reach them. Assuming they got the message and replied immediately, their response would reach us 2.2 million years after that. I would say that would make a "teleconference" all but impossible.

Answer 9

No problem! All you need is a powerful enough transmitter and a lot of patience( a message will take 2.2 million years to get there and the same to get back). Until we can use wormhole or other methods of avoiding the light barrier we are limited to 300,000 kms/s.

Answer 10

message in a bottle man. Thousands and millions of years from now the waves could reach some intelligent life. we'll all be dead though.
