Alien Earth 13 light years away

...loaded with nukes. If they're anything like us you know they will do the same thing. We have to get them before they get us. They've seen our broadcasts of Laverne and Shirley, they know what we're capable of.
 
crazy how far away that is, and how close it is, relatively.

there's nothing there, though. if life on those types of planets were so common, we would probably know about it. there would be some crazy alien mofos running around somewhere

Because life would have to develop exactly the same way and in the same time frame as our planet? 😕

eh, I meant somewhat evolved life. considering the title is "alien earth." some creepy crawlers maybe

I suppose some sort of "life" is possible
 
Given the time window of how long "intelligent" life has been on Earth, the likelihood of the Alien Earth also having "intelligent" life at the same time is practically nil. That means it's ours for the taking!!!
 
I don't doubt for a second there are tons of Earths everywhere with life, maybe some not as primed as ours, maybe some well beyond. One thing for sure is none of them have figured out how to break or approach light speed or we'd probably know by now.

Maybe it will never happen and the planet will go extinct before we see it happen, and same goes for those planets.

IMHO of course.

think of the timescales. Say the dinosaurs had become intelligent and got as far Roman tech before they died. Even if it took 1 million years for each cycle there has been enough time for hundreds of civilization to evolve and die just on earth.

Now with another planet, who knows how old it is or at what stage it is at. Not only are we separated from any life forms there by space but also time.

That's not necessarily true. Even if a civilization broke the speed of light barrier through some cool science-y way, it doesn't mean that we'd have heard of them. The galaxy is a damn big place. Even with FTL technology, what're the odds that they would have discovered this tiny speck in this remote corner of the galaxy right about now?

And I would imagine that, if FTL technology is even possible, it's still more difficult to travel longer distances than shorter ones. I mean, maybe 1 in 100 civilizations are smart enough and last long enough to develop FTL travel - out of those, how many are able to go more than a few hundred light years in any direction? How many are able to travel significant distances within our galaxy? How many can travel to other galaxies?
 
No need to go faster than light.

13 light years away would only take a ship a little over 5 years travel time with 1g constant acceleration half the way there and 1g deceleration for the latter half.

Although on earth it would appear to take almost 14 years to get there due to relativity.

You would think we wouldn't be too far from being able to launch a unmanned probe capable of such a trip.
