The laws of physics mandate the rocks will NEVER match the speed of the jets that are accelerating them.>>
And why NOT...IF the water molecules behind that rock are FASTER (as you say) and they are pounding into the back of that rock? Why would the rock not be accelerated by that?
I don't want you to just jump back into this discussion and pretend there are not important questions you have so far NOT answered.
>>Virtually all of the water will accelerate to a speed five orders of magnitude (100,000x) faster than the escape velocity of the rock. Keep in mind, the escape velocity mentioned is at the surface of the rock.>>
Totally irrelevant if at some point the rock and water molecules are at nearly the same speed. That rock WILL capture them if they are close enough and slow enough (relative to the rock).
>>The water will accelerate faster than the rock for as long as there is an equal force applied to both of them. >>
Once the water gets to the speed of the jets it will no longer be accelerated...same goes for the rock. The time it takes will be different...but SO WHAT? You seem to be under the delusion that the rock NEVER gets up to the speed of the jets. And this could happen EITHER inside the chasm during the 10 mile (now 50 mile...with Brown's new model) trip up the chasm...or after all of it is in space.
>>Go ahead.... explain what force is going to accelerate the rock up to the same speed as the water without also accelerating the water.>>
I did. 17kmps jetting water will not speed up the water already going 17kmps but it would speed up 10kmps rocks. Got it? Did you run your statement past any physics PhD's before you made it? I gave you a very good analogy. Tossing a log into a stream...at first the water rushes by the log, but eventually the log and the water are going about the same speed. RIGHT?
Indy:>> It is true a single packet of water would go further in a given time and it would keep being ACCELERATED to faster speeds so long as it is going slower than the jet. But the same is true of the rock...it just takes it longer to get up to that speed (((( Pi comments "to get up to that speed" means ACCELERATED. ))) of the jet. When it DOES get up to that speed (((( ACCELERATED )))) then it is going the exact speed that the water is...so it can easily capture by gravity that water which is nearby the rock . AND once in space, even if some water is faster (starting behind the rock) then as the water catches up, it could be captured as it collides with the rock or other water around the rock. Your claim is untrue that the rocks could never obtain a cloud of water vapor surrounding them. >>
Pi>>All of this has already been addressed.>>
That is simply an UNTRUE statement. You want to play word games AS IF I have said that acceleration is not needed. NO...my point (and you KNOW IT) was that HOW LONG IT TOOK for that rock to be at the same speed as the water IS IRRELEVANT. Stop playing word games and START being truly responsive and ADDRESS what you CLAIM you already have...but have NOT.

Like I said before...the TOUGH STUFF you ignore. This was something I wrote BEFORE you replied to other stuff I wrote. I should NOT have to repeat over and over stuff just because you are afraid to admit I've made a point that you have no answer for. After SOME point it is fair for me to be b-ing (complaining) about your failure to reply to my fair points and questions. And YOU should stop YOUR b-ing about my calling for you to actually reply to my tough stuff...rather than just taking little pot-shots when you think you see an opportunity to score some point of your own. You'd like to see yourself as a tough debater...but you aren't tough enough to readily take your medicine when a non-scientist (me) shows you to be wrong.
>>The first strategy is to make a guess at how much time will be needed to provide a substantive response. If the time is brief, I'm much more likely to address it. If it's going to take a couple hours or so I may only get to one or two per day.>>
Doesn't take 2 minutes to write "yeah, Indy, I have to admit...eventually that rock will be sped up to the speed of the water and it will gain a sail." NOT DIFFICULT...except for the pride part.
>>Yeah... if you complain, then I review the priorities. When you think it's that great .... even when it isn't.... it's pretty clear I should move it up on the priority list (as in post #39).>>
So MOVE IT UP.
