Let's say we colonize Andromeda. How would we communicate with a planet in Andromeda? The messages will literally take millions of years to arrive.

>Andromeda 2.537 million light years
>fastest man made object ever in space 25 miles per second
>would take 18.875 billion years to reach Andromeda
>Andromeda–Milky Way collision in about 4 billion years

Without FTL travel, by the time you get a ship to Andromeda it will be part of the Milky Way.

>How would we communicate with a planet in Andromeda?

The same way we colonized it. Duh.

well theres plenty of ways to go faster then 25 miles per second

If you have the technology and knowledge to colonize Andromeda, you already have an answer to you question.

Quantum entanglement communications

Just send messages in FTL mail delivery ships.

Contact the shuttle service, kids.

By the time individuals got to andromeda, the languages would have diverged so much we probably couldn't communicate even with an instant signal. Also, what arrives in andromeda will probably a new subspecies of humans or a new species altogether.

Solar Light Houses

Basically, we have large flat panels that orbit the sun. When we want a message to be sent, we open/close shutters on the panels to block/allow light. They bascially bang out 1s and 0s slowly to turn the sun off/on to the observers on Andromeda.

This is the only way you can circumvent signal attenuation.

someone do the math, how fast to you need to be to be going to reach Andromeda in less than 4 billion years?

engineered worm holes?

Remember that it's also coming towards us, take that into account when you determine the time to reach it.

This seems the answer for even solar-system-to-solar-system communication. Theoretically it'd only need to be big enough for whatever form of particle we use to communicate.

But if Andromeda and the Milky Way are accelerating toward each other, that would shorten the amount of time we would reach Andromeda... we would obviously make it there in less than 4 billion years.

Take your pedophile cartoons back to .

Hahaha

Don't. The new MODS are weeb degenerates.

Fuck them.

>Getting mad at weeb images on Veeky Forums

Time telepathy, using genetic material delivered by a comet full of extremophiles, sent via a wormhole.

Presumably, using the same science fiction magic that got the colonists there in the first place.

Or, alternately, we just don't communicate with them.
