Title: Galactic spin and its effects on spacetravel
Post by: Angelfish on July 21, 2009, 07:14:34 pm
When looking at one of the lately user-generated maps, I noticed the galactic spin being displayed in it too. Now, I'm wondering whether that galactic spin would have any effect on spacetravel. For example, moving from Sol to the Wolf systems would take shorter than traveling to the lyrae systems.

What are your thoughts on this?

Presumably these coordinates are fixed in Hyperspace, and spinward/antispinward are just useful directions to know (sort of like east or west) in order to locate things.

I don't know how UQM treats it but in the real world, thanks to relativity, it wouldn't make a difference unless you're uncomfortably close to Sagittarius A.

If you're in the galactic plane, over a large enough time scale you would reach stars rotating toward you faster than stars rotating away from you if you traveled at a fixed, non-relativistic speed.

But you're not going to go in a fixed, nonrelativistic speed, in real life. You start with the velocity of wherever you started.

In HS, who knows? But you'd have to be basically crawling through HS for the extremely slow galactic rotation to make a noticeable difference.

If you call 500,000 mph "slow". But I suppose at the galactic scale this is slow. That speed is according to this (http://www.pa.msu.edu/feature/Halo2.html) site where they talk about a fairly recent scientific paper in the journal nature. This is possibly unveiling some interesting aspects of the Milky Way Galaxy.


And on an interesting side note:

"Reid and his team also determined that the sun is closer to the center of the Milky Way than previously thought. Our galaxy is moving toward its twin, the Andromeda galaxy, at about 100 km/second, although it's not known whether the two galaxies are on a direct collision course or will pass by each other."

That is according to this (http://www.windows.ucar.edu/tour/link=/headline_universe/olpa/MilkyWay_30Jan09.html) site.

Reminds me of an Isaac Asimov book. I think it was called Nemises. It talked about the chance of one star system passing through our solar system. Though the book over-looked some obvious points in the matter, it was still an interesting read.

The Milky Way is moving toward Andromeda, but moving through the Galaxy won't be affected by this
