    3d Map Universe
AI Thread Summary
A sci-fi author, Rusty Williamson, is seeking assistance in plotting a course with distances and galaxy stopovers between the Coma Wall, Earth, and the Great Attractor. He has explored various online 3D and 2D universe maps but hasn't found suitable options. Respondents provide a link to a detailed digital universe map from the American Museum of Natural History and emphasize the vast distances involved, noting that 400 million light years is a small scale in cosmic terms. They also highlight the challenges of obtaining data in the direction of the Great Attractor due to dense galactic material, which complicates observations. Rusty acknowledges these difficulties and plans to revisit the suggestions after a brief delay caused by home remodeling.

Hello,

I'm a sci-fi author and need to plot a course with distances and galaxy (cluster and super cluster) stop overs between the Coma Wall, Earth and the Great Attractor. I've looked at a few online 3D universe maps and 2D maps but have not found anything ideal. Any suggestions?

Thanks so much for any help you can offer!

How about this one:

Don't know, whether you've already checked it.

400 light years is exceedingly close by. That's just a tiny fraction of the nearby stars within our own galaxy. It's about 10,000 light years to the center of our galaxy, for a sense of scale. The Coma cluster is over 300 million light years away. The closest nebula (the Helix nebula) is about 700 light years away.

Still, fresh_42's answer should be a good one. If that doesn't get you what you need, let us know.

That might be useful but some points. As already pointed out, 400ly is nothing in space terms.

Second, it's very difficult to get any data in the direction of the great attractor. Thats beyond our galaxy in the same direction as the centre of the galaxy, which is dense and hard to look through. That's the reason when you look at maps of the universe, it looks like a dumbbell. We simply can't observe very well within the plane of the galaxy.
 
Thanks for the replies! Work on book sidelined by home remodeling... [:-(] I'll check all this out in hopefully a few days...sorry.

Forget map showing Great Attractor...I forgot we can't see in that direction (unless I'm behind the times).

Thanks,
Rusty

PS: Whoops...sorry, I meant 400 million lg on OP.
 

Thread 'Are Clone Ships a Better Alternative for Space Colonization?'

We've just had an interesting thread about generation ships, but I don't think that that is the most reasonable way to colonize another planet. Fatal problems: - Crew may become chaotic and self destructive. - Crew may become so adapted to space as to be unwilling to return to a planet. - Making the planet habitable may take longer then the trip, so the ship needs to last far longer than just the journey. - Mid-flight malfunction may render the ship unable to decelerate at the destination...

Thread 'Looking for story advice on ancient aquatic reptile breeding grounds'

I'm looking to pick the brains for a fantasy story of someone who knows a little about how ancient aquatic reptiles (~65Mya) might have migrated to breeding grounds in ancient Atlantic Ocean and its shores. The premise is that such creatures, last seen 65 million years ago, managed to survive through the ages on the shores of mid-Atlantic islands - now gone - and ended up in (relatively) modern times. The questions are mostly about how their migration patterns for breeding might have...

Thread 'AI Consciousness?'

I know this topic is extremely contraversial and debated, but I'm writing a book where an AI attempts to become as human as possible. Would it, eventually, especially in the far future, be possible for an AI to gain a conscious? To be clear, my definition of a consciousness being the ability to possess self-created morals, thoughts, and views, AKA a whole personality. And if this is possible (and let's just say it is for this question), about how long may it take for something to happen...
