Stars Ride the Milky Way Arms
Here is our Milky Way:
This map is about 1,000 pixel wide, at 1 pixel : 100 light years scale. For the light (at its speed 300,000 km/sec) it takes 100,000 years to cross the Milky Way. White surfs are arms of the galaxy, and these arms are very stable, they last billions of years, and they whirl very slowly: as you can see, no arm has completed a full round yet in more than 10 billion years of the Milky Way lifetime. But our Sun has made about 4 round trips just during the last billion years. Computer simulation just for two arms shows how arms remain stable with stars passing by:
There is something enigmatic about these arms that seems to attract stars. It appears that time inside the galactic arms runs a bit faster than outside the arms, and such difference in time flow creates gravitational effect:
Stars really surf these arms: when they enter an arm, they turn along the arm (by green arrow 1), and when exiting the arm, they are pushed away from the arm (by green arrow 2)— and the ride is over, until the next arm! Besides that, the Milky Way is not flat, even its arms are thick tubes, and stars periodically rise over and dive below the galactic plane on their way around.
If you want to learn more, for example, how the propulsion system of flying saucers is based on the same physics/gravity as of our Milky Way, check out Time Matters or Beyond Cutting Edge with Bob Lazar. Refresh by Yourself eBook on Amazon! if you don’t see all 52 chapters.
