Snip
Didn't I just suggest Centripetal/Centrifugal Force would do
that??
If not, that is what I was trying to do!
Centrifugal force is what spreads the galaxy apart--it is not what
holds it to its center.
... and *what does Centripetal Force do* , Mark??
Centrifugal force pushes rotated objects out--does not hold them in.
... and *your* answer to *the question I actually asked of you* (the
question I've highlighted above) is ...??
I just told you what it does. It pushes an object rotating around some center
outward.
No, you didn't, you told me what *Centrifugal force* does. I asked you
what *Centripetal Force* does. Can you see how one word is spelt
different to the other??
I don't care how it's spelled. People still don't know what they are talking about.
For you edification ....
Centrifugal force .... https://en.wikipedia.org/wiki/Centrifugal_force
and
Centripetal force .... https://en.wikipedia.org/wiki/Centripetal_force
So, if you even bother to read those link, you might realise they are
different forces acting upon an object!!
