I'd have a look-see into the heart of the Milky Way

That would be a good trip, but I'd like to stay a bit away from the centre, massive black hole and the like. Also the density of stars, asteroids, black holes would make it a very dangerous region!

Personally, I would LOVE the ooportunity to explore the Edgeworth-Kuiper Belt, the Scattered Disk, the Oort Cloud i.e. the 3 dimensional space in between here and Proxima Centauri. REASON: to unravel once and for all, the TRUE census in the immediate solar neighborhood of all the MAJOR objects (substellar BDs; substellar mass clouds; and planets) that may as YET be unaccounted for.
Can I come ?

I don't know if you have seen this abstract, map of the universe.

There would appear to be a lot of detail missing from our veiw outerplot MPC

A lot of the information you have just given about Rigel Kentarus is available from Solstation.com.
I find the theory of the proxima moving group by Anosova et al (1994) mind blowing !

My favorite 3d model of the orion arm doesn't include the Proxima moving group.
It would be interesting to see.
You may find a project of mine interesting.

Yeah, it was brought to my attention by a pal of mine. There is some jarring problems with Proxima i.e. it is a very active flare star indicating it may ONLY be a billion (i.e. 1 Gyr) old or so. Whereas in the case of BOTH Alpha Centauri A and Alpha Centauri B, they are at least 4.85 Gyr (some actually say ~6.5 Gyrs) old. UNLESS we are missing out on something here or hmmm...could Proxima have been a "captured" companion?

Okie dokie Zephyr I'll do so and let you know what I think soon enough.

Hehehe SURE thing why not? while we are on it...and maybe a couple of CHICKS, toys, water beds and some viagra to keep us entertained throughout the trip as well h34r:

:P I would most definately be in on Zubrins page! I would ask the momo2nd I arrived, what is your definition of success? And reply, motion to redirect. Spread the word. :P

Hi everyone, I'm new to this most interesting forum. Just a few words.
rajasun; If your post which followed was a few words, I know a few kids who would like you to write their essays.

But truthfully, it was very very informitive, interesting, and an awful lot to digest.

I can't honestly say I know whiether or not Proxama is a member of the Alpha Centauri system, but I do know it is very close to the other two, and it is commonly accepted that it is a companion to at least one of the other two.

Quote:
Now let me also take the opportunity to address a long-standing controversy over whether our very own Sun can support a remote, ULTRACOOL, VERY LOW MASS (VLM), DIM companion with a separation up to projected distance of Proxima from the Alpha Centauri AB pair.
I hope what followed that was not a plug for the Nemises theory, although I saw nothing specificly addressing Nemises. It appeared to me you were simply addressing wheither or not our Sun COULD support a companion star based on it's gravity well. Which if is what you are convaying, I can't think of anyone who will disagree.

Quote:
The gravity well of the Sun will end when its gravity at a certain point in space equals the gravity from another star.
It makes since, and perhaps even goes without saying, but it becomes thought provokative when you consider the nearest surrounding stars.
You gave Alpha Centauri as an example that the gravity well would be exactly halfway if it were a lone star, (assuming you are refering to star A which is nearly equal to our Sun in mass, gravity, and energy output). But since there are two other stars in the vicenity and even though they are smaller then our Sun, that gravity well should favor Alpha Centauri over our Sun and by quite a bit.

Which by the same token, Our Sun's gravity well extending toward Barnard's Star should greatly favor our Sun, seeing how Barnard's star is like what a tenth of the size of our Sun.
I can see that same truth with most of the nearest stars, which are red dwarfs much like Barnard's Star.
And I would suppose Sirius, a blue giant about twenty times the size of our Sun
would be favored in the gravity well.

But I'm curious about a red giant such as Lacaile 9352, which has a bigger size then our Sun, but isn't nearly as dense.
Or a binary system where the combined mass isn't so overwhelming as Alpha Centauri, such as Luyten 789, or Struve 2398, or perhaps even the Groombridge 34 pair. That gravity well thing is interesting indeed.

You gave a lot of math which is way over the head of my limited high school graduate understanding with Alpha Centauri, reguarding a possible 4th companion,
and the position of star C.

Perhaps you can make it more simple for people like me by giving a compairison.
Say our Sun was Alpha Centauri A. At what distances and positions would star B, C, and the theorized brown dwarf companion be in relation? Using our Solar system as reference.

Guys, guys,
I believe I said in the introduction of this space travel senero that you either provide a partner, or are willing to pair up. Procreating would be required on this journey, but please don't procreate too much.

And if you are going to bring viagra, you will need a means of birth control as well.
After all the voyage would be very long and boring, with little better to do, but we don't want an overpopulation of little ones either.

Victoria,

I'm not seeing where your posting has to do with the rest of the string, unless I missed something. Was it a response for a different string? If so, I can move it for you.

I wouldn't mind seeing Antares, but yes I am glad that procreating is allowed, who is supplying the Viagra?

Finally the haze has cleared, the absurdities are left far behind and I am now focusing on happy trails. All who have partaken in the invention of my neverending journey should be honoured. A legacy? A pioneer vs. volunteer. I would seek a place for chaenge

This journey will take the rest of your life and still not be complete. Although you will get to visit at least a few stars before you die, it will take years, and for some of the little bit farther ones, decades to get to them.
Not true. As you get closer to the speed of light, relativistic effects kick in - time slows, distances get shorter...So you could go to another star in a matter of weeks/days/hours...however years will pass by back on Earth. For a photon of light, time is stopped completely!

You wouldn't need to go faster than light!

Personally, I'd head for the 4th planet around the star Altair...looks pretty nice from what I've seen in "Forbidden Planet"!!!

You haven't seen "Forbidden Planet"? Great movie, my friend.

No, no McDonalds franchises on that planet, pal! (...yet!)

By years, and decades, I did mean back here on Earth. Yes for those on the ship the journey will seem like weeks, months, or years depending on just how far one travels.
I believe I placed in the scenero that we will travel at 5 times light speed.

As for procreating, not just allowed, but encouraged (to a reasonable point) and we will have to supply our own Viagara, unless one of our passengers is a pharmacist. (which is not a bad idea the more I think about it)
After all Viagra is expensive (except in Canada) and I'll be hard pressed to afford my own. But then that pharmacist would come in quite handy.

Excellent! however, is it possible to have an extensive DVD collection so we don't go mad...wait a sec - encouraged procreating...ok the DVD's are not required

To further demonstrate, I can only recomend (if you have Java)
Solstaion.com (my favorite)
or
Anders Anderson's 3d starmap (play with it, it's fun )
