Star Charts vs Star Motion

[junglelord]

I have seen several discussions on the forum about the motion of the local body of stars.
For instance I was reading about Sirus and its distance from the sun and it passing us a few million years ago.

The greatest catastrophic event that ever occurred to the Earth was the K-T event sixty-five million years ago. Sixty-five million years is a very short time for a star to travel as the Sun, traveling 20 Km/second, has gone only 4 1/3 light years in that time. If the star that encountered the Sun is traveling the same velocity as the Sun but in an opposing direction, it would be about 8 2/3 light years away from the Sun. The star Sirius is 8.7 light years from the Sun.

The solar system's formative planetary order has been changed by a disturbance caused by an encounter with a star (Sirius) sixty-five million years ago when Neptune and Uranus were between Mars and Jupiter. In that disturbance Neptune lost four of its five satellites that became free bodies around the Sun and interacted with other bodies of the solar system.

It is said by the Dogon that the system of Sirius has a third companion and that this Sirius C has the same orbital period as Sirius B but a greater orbit. If this is true, then the unusual nature of Sirius B should be taken into account.

If Sirius B is the jovian planet of that system, then Sirius C is the saturnian planet of that system with an orbital distance about twice Sirius B. An orbital calculation of the mass for the system of Sirius with Sirius C at twice the distance but the same period as Sirius B gives a calculated orbital mass of about 5.5 solar masses for Sirius A.

How close to being correct is the map below? Can you put this into spiral motion?
I have a minds eye view of what must be happening...it would be nice to have a video.

Sixty-five million years is a very short time for a star to travel as the Sun, traveling 20 Km/second, has gone only 4 1/3 light years in that time.

Shoudn't that be 4 1/3 thousand light years.

20km/sec is only 0.0000667 of the speed of light (300,000 km/sec) so it should have travelled that percentage of the distance light has travelled.

0.0000667 x 65,000,000 = 4,335

However, I understood main stream theory expects the sun to be travelling at closer to 220km/sec which would make it around 47,000 ly travelled.

I would like to add I'm not convinced stars are orbiting the centre of anything. My belief is that the stars are ejected from the centre of the galaxy in a similar structure to a catherine wheel.

Pause this around 36 secs.

The only direction we are travelling is away from the centre which also means we are travelling away from all nearby stars as well as the galaxy expands. Not entirely sure if this fits in with the EU or not.

I never even bothered doing the "math" for that statement, which I pulled from the Earths Resonance thread.
Besides that static star chart, who anywhere, has a dynamic motion chart of the local 20 stars? The sun is moving in the general direction of the star Vega. (Alpha Lyra). Or so I read.

I do know that Constellations change over timescales of 10's of thousands of years, because the stars in the neighbourhood of the Sun all have different velocity and directions. Again, or so I read.

I found this one for instance in how we will see the Big Dipper in 5000 years

I thought that potential star motions would be based on assumptions anyway. Is there any way of measuring their movement accurately in the relatively minute amount of time we have been charting them?

As I mentioned before, I am not convinced we are orbiting the centre of the galaxy. I find it hard to accept that it is possible for the force at the centre of the galaxy to be able to organise the arms into ordered structures accross thousands of light years. IMO it's far more likely the structure is determined initially as stars are ejected from the centre as it spins, and we are therefore all moving away from the centre at similar speeds. In addition, we would also be moving away from each other as we spread out.
