Re: acceleration

Hi cavediver,

I have another one of those questions I don't want to be a stupid question so I will ask it.

The explanation for the rock falling and the expansion of space between earth and stone dropped trigered my question.

If expansion as has been explained to me several times is true.
Everything is fixed with nothing moving only space expanding between those fixed objects

Could you explain to me how that two of those objects that are 2.5 billion light years apart at present could end up in the same place?

God Bless,

Re: acceleration

Thanks Percy,

Note that the speed with which distant mites are receding from each other has little to do with the speed or direction at which they are walking, because the expansion speed is so much greater than their own.

I understand that in our Milky way stars, planets, moon, sun, and other stuff moves around in our galaxey.

Sorry Percy, I will try to be clearer in my thoughts in the future.

Now am I to understand our entire galaxey moves around, or is it stationary with space expanding between it and all the other galaxies?

I understand that we have a star that is saying good-by to our galaxey as it is streaking toward escape from our Galaxey at well past excape velocity.

Re: acceleration

Thanks Percy,

Percy writes:

In the balloon analogy, the mites walking around on the surface of the balloon were analogous to the galaxies moving around within the universe, so yes, of course, our galaxy is moving. And so is the nearby Andromeda galaxy. The Andromeda and Milky Way galaxies are on a collision course with an estimated time of impact about 2.5 billion years from now.

But that raises more questions.

Since they are 2.5 billion light years apart and are expeced to collide in 2.5 billion years. That means that they are traveling at light speed toward each other.

If expansion is true and expansion it taking place at light speed and is accelerating, they would never be able to collide.

If there is zero expansion and they are traveling at light speed toward collision that can happen in 2.5 billion years.

Or am I missing something there?

glaring mathematical mistake Percy and Cavediver pointed out.

I was quite satisfied with the answers I got from Percy and cavediver. And Percy pointing out my blunder. Too bad you had to waste a rant.

I am still waiting for information from you.
