The Milky Way Galaxy is 120 000 light years in diameter and Andromeda is little bigger;
160 000 light years diameter.
The Milky Way contains 294 billion stars but Andromeda 406 Billion stars.

but I agree that the Milky Way is little more massive than Andromeda due to Dark matter.
The collision that will happen for the sister galaxies will create the giant elliptical galaxy Milkomeda.

The 100 billion Galaxies were all created by Jehovah, the Lord for His Father Eloheim.

So to sum up if this new model is applied on a universal scale does this necessitate a rethink on the size of the universe and the speed of expansion (ps im new to this so please be gentle).

um in response to greg “showing that the Sun is moving at 600,000 miles per hour around the center of the galaxy, or 100,000 m.p.h. faster than past calculations suggested. ” means that the speed is relative to the center of our galaxy in this article
if they were to measure the speed of our sun relative to our universe they would find varying results bevcause our sun revolves around our galaxy at some periods our sun would apear to move away from the center of the universe faster then when our solar system is at its oppoisite end of our galaxy and moving towards the center of the universe thus showing a slower speed away from the center but getting the fine measurments out of the way is the best way to start measuring, 100,000 kms is a huge difference and will go a long way in the future in plotting speeds and points in the universe

Well, the headline’s misleading because nothing has changed except our measurements. But anyway, in regards to what Greg has posted, considering this is the same article, paragraph 3 pretty obviously refers to how they calculated the statement in the first paragraph, which you already agreed was correct.

And it’s an accelerating expansion of spacetime. There is no frame of reference for us outside of the visible portion of spacetime we reside in, so we can’t tell if the whole of spacetime is moving or not. We can just tell it’s expanding, because it’s moving away from us at an accelerating pace.

In the first paragraph you correctly state a reference point for the calculated speed “Sun is moving at 600,000 miles per hour around the center of the galaxy,”.

However, in third paragraph, you fail to mention the reference for which speed you refer: “determine the speed at which our sun is moving,”

So my point is, when you say speed, you must really tell us “relative to what”. The flaw in your argument is that you are assuming the center of the Milky Way galaxy is “fixed” and thus non-accelerating.

So my question is, if you include the possiblity that the entire reference system is accelerating, doesn’t that throw off the entire neat little package of assumed circular motion for which you have inexplicitly assumed!

Tell me how the speed measurement corrects for or accomodates an accelerating galaxy in an accelerating universe?
