AlphaNumeric. I sometimes forget what a point scoring idiot you are, looking for every trivial chance to put someone else down. Next time I'll say SOLID matter so you can't score points off of it. Of course, this is just down to BB dogma anyway so it's not as though we were talking about something real. Both our galaxy and the Andromeda galaxy are attracting each other gravitationally, so both are moving towards each other at accelerated speeds, so not normal speed as you would have realised had you given it 1 second's thought, which is asking a lot of you. Not being a trusting person I checked the wiki and found we are approaching each other at 100-140 km/s. They used a figure quoted from space.com . hypertextbook comes up with 130 km/s. Where was your figure from? The BB has serious problems with it. Just because someone can identify distant star clusters, how does this equate with their personal knowledge of the BB? They believe it because that is what they have been taught. not because they have done any research on it, or in most cases, ever given it a moment's thought. My insults can't be that bad if you quote them back to me. A pity they don't have a text book which you can quote insults from. Why don't you display any knowledge which could not have been quoted from a text book or an internet site? An educated 12 year old with a search engine could do as well as you do. A PhD student who spends all his time on internet forums? Like a pig with wings.
