Boyd Bushman of Lockheed Martin drops two stones off a high tower... He gets any man off the street to bring him the one that hits the ground first...
Guess what? One hits the ground first... so much for Galileo and Newton
Here is a good one... from NASA
"Numerous space physics and plasma theories are being revised or overturned by data gathered during the Tethered Satellite System Reflight (TSS-1R) experiments on Space Shuttle Columbia’s STS-75 mission last March."
So it seems even NASA says old school science is out the window LOL
"Perhaps the most significant finding," Stone said, "is that tether currents proved to be up to three times greater than existing theoretical models predicted prior to the mission. With the amount of power generated being directly proportional to the current, this bodes well for technological applications." "Reversing the direction of current flow puts the system into an electric-motor mode," Stone explained. This harnessed energy could furnish thrust for reboosting a space station, satellite or Shuttle in a decaying orbit.
[..]
Tethered Satellite System investigators have just begun to scrutinize the data from STS-75. They expect that it will reveal more answers to questions about the workings of the Earth's upper atmosphere, its physics and the electrodynamic applications of tethered systems in space.

Now just a darn minute here. I have always said the neutral point is at 43, 495 miles from the moon and I use Werner von Braun and the Apollo astronauts as a source of information. I make no calculations of the moon's mass. None.
I would respectfully request a clarification or retraction of your statement above yfxxx. Thanks.

Perhaps for the record you could state those qualifications so we may know what your expertise is yfxxx? Thank you, it would make it easier to judge your position

I don't recall seeing John provide any calculations or formulas for his 43k. I believe that this is a misstatement. I could be wrong, and just missed it...but like John says, he is referencing texts from 64, as well as Von Braun. I think that, given your position, you would be best to debunk him by showing how Von Braun was wrong, or that Mr. Lear misinterpreted the information that he read?
I mean, in the end, all you are doing is arguing with a lay person who is using a very, very respected physicists own statements. Your argument, then, is not with John, but with Werner Von Braun.
Just a thought. It would seem that in your fervor to debunk John you are starting to misrepresent information.

If you think its Bull say your peace and Move Along!
Id like to see some of you fools post your credentials for all to see.
But wait that would be fair play wouldnt it and most of you wouldnt have a leg to stand on in comparison. One again I believe John's genuine and most members calling him out consistantly are nothing but trolls and naysayers whom should belong too the world is flat club. And I thought there were rules against personal attack threads. So what gives mods?

I don't know how the moon was formed but I believe it was towed or 'placed' into orbit around the earth many thousands of years ago. Perhaps tens of thousands of years ago. Whoever did that managed to place it in 'rotational lock' so that one side of the moon faces earth at all times.
[...]
Of course, the idea that it 'broke off from the earth' or was wandering in space and 'captured by earths gravity' is flat out nonsense, a fairy tale for the uninformed.
Some have proposed that the moon is a gigantic space ship. I wouldn't disagree with that.
However, Mr. Lear does not apply said laws correctly[*]. With these incorrectly applied laws, he can only arrive at von Brauns "neutral point" value, if he assumes that the moon's mass (and therefore surface gravity) are much higher than the textbooks say. And since Mr. Lear trusts von Braun (as I do), he concludes that the moon's gravity is indeed higher than what "established science" says.

As far as I can tell, Mr. Lear's credentials as a physicist or astronomer, which are the only ones relevant in the recent discussion on this thread, are absolutely non-existent.
If you think its Bull say your peace and Move Along!
So you think everyone on ATS should have the right to post "Bull" (as you called it) without being challenged?!
Id like to see some of you fools post your credentials for all to see.
I just did, a few minutes ago.

!!! If nonsense had gravity, your post would have collapsed into a black hole!
Just for the record, Mr. Lear: What are your credentials as an astronomer or physicist? If there are none, why should anyone regard statements like yours above as anything else than the incoherent ramblings of a disturbed mind?

Honestly, I mean no disrespect. I am fairly blunt and straightforward, so don't misinterpret my delivery.
I don't understand the duplicity. If you agree with Von Braun, and you agree with his 43k distance, then what about the distance that your scientific discipline predicts? Am I missing something?
you, John and I go to a hotel while out of town. We are told that we get a group rate of $30 (but you or john sleep in the tub, as there are only two beds ). We pay $10 each and go upstairs. Shortly, the bell hop runs up and states that there was a discount tonight and it is only $25. So, he keeps 2, and gives us each 1 back (totalling $5, right?).
If you figure that we each paid $9 net (equaling 27), and the hop kept $2, then that is only $29...where did the other dollar go?

Um, that only works in a vacuum. You know, like space and on the moon. There's more acting on an object than gravity... when you're under an atmosphere, that is. Remember
Reading into that a bit much aint ya? Why didn't you link to it?
How is that related, in any way, to the science being discussed here?
Interesting nonetheless so, thanks.

Nobody disputes the "43k" figure of von Braun. What is in dispute is Mr. Lear's "theory", which takes this value and uses it to arrive at a much higher moon mass (or surface gravity, which is equivalent in this context, because Mr. Lear accepts the textbook value for the moon's size).
[..]
To say it again: I do not dispute von Braun's claim, that the Apollo spacecraft experienced an accelerational "neutral point" at ~43,000 miles from the moon. What I do dispute is Mr. Lear's reasoning that this fact leads to the conclusion that the moon has a higher surface gravity than said by all textbooks.
[...]
[*]Technically, he uses Newton's law of gravity in a way which applies only in inertial frames of reference, when he should in fact apply the (much more complicated) laws of motion for a non-inertial (in this case, rotating) frame of reference.
[...] my arguments about the dynamics of the earth-moon system, and how the textbook values for moon gravity, von Braun's observed "neutral point", and calculations of Lagrangian points all agree with another.

Just because he strikes a nerve with his presentation and you can't refute it, resorting to such tactics as you display, while quite common amongst the scientific community when trying to discredit their peers or their peer's theories, is really getting old in here

I can (and did) perfectly well refute his claims about the moon's gravity. However, it's obvious that not all people understand my arguments. May bad. If you think that the "scientific theories" of someone whose track record includes lots of "great piloting" but no science are more believable than those of many accomplished physicists, it's your choice. But is it a good choice ?
