It's been done. You're wrong.
I see it went over yours too.

Not really sure what you mean there. 1c (or c) is twice the velocity of .5c, so the distance traveled is twice that of a .5 c object. c is an absolute velocity, so .5c is also an absolute velocity, measured in the absolute frame of light which travels at c.
It is like trying to talk to someone in a Monty Python sketch, only it is not funny.
I wouldn't be laughing if I were you either, your world is crumbling! Literally!! Mass evolves to space! Mass gets less dense over time! The earth came from the sun!

Trolls tend to follow certain patterns of behaviour that may include:
- Posting of similar responses and topics repeatedly.
- Avoiding giving answers to direct questions put to them.
- Never attempting to justify their position.
- Demanding proof or evidence from others while offering none in return.
- Vanishing when their bluff is called, only to reappear in a different thread arguing the same point.
- Deliberately derailing discussions onto tangential matters in order to try to control the flow of discussion.

Hmmm, wonder why MotorDaddy gets preferred treatment. He seems to conform to all these indicators.
I see nothing that he adds to the discussion. If I were .... never mind.
Preferred treatment?? I get banned faster than Chinglu at a anti-Chinaman festival!
Not surprising. I notice you deny none of the points in the anti-Troll rules.
James, you are making the same mistakes that I keep replying to and telling why you are making the mistake. You fail to understand your problems and then you come back and repeat the same conceptual mistake again and again, which causes me to have to repeat my self over and over. You're wrong, by definition.
Let's start from scratch of what we know and determine motion, shall we?
There is two rockets in space. There is no change in distance between the rockets.
Do you agree so far?
Motor Daddy:
I write two or three detailed posts, including an explicit addressing of the questions you asked me, and this is the best you can do? Is it time for you to run away again?
Do you have any response to what I wrote, or are you just going to dishonestly pretend I never wrote it?
I will point out your errors when I feel inclined to do so, and I will post inconvenient reminders of where I tried to educate you previously. But I will not waste my time on you since you are obviously unwilling to learn and/or incapable of it. Besides, things have got to the point where I doubt your good intentions and your capacity for honesty, and that does not make for a useful learning relationship.
I'm not interested in playing your personal attack game.
I don't for a moment think that MD is intellectually dishonest or evasive for sticking to his views. And I might note that the personal comments have come from others than him in most cases.
In her book - Science: A Four Thousand Year History” (2009), Patricia Fara of Cambridge University wrote that “there can be no cast-iron guarantee that the cutting-edge science of today will not represent the discredited alchemy of tomorrow”. I think there's a message in that for all of us.
Or have we reached that unique position today, where we are finally at the end of all knowledge ?
My words were offered for your benefit since you don't do math. I think there were just the right amount of words to say what the formulas would otherwise say. Once you understand the way forces act on the pendulum, you will get past your misunderstandings about relative motion.A lot of unneeded words.
Unless you understand how the forces are transmitted, and that they add, you will lose sight of the relative nature of all motion. Presumably you would not argue that there is an absolute force in the universe. As I said earlier, acceleration is the instantaneous slope on the velocity curve, that is, it's relative to the velocity an instant earlier. But to make this easier for you, I traced out the forces involved so you could reason through the errors in your thinking.When the pendulum swings it indicates an acceleration.
Hardly. You would certainly need to understand how forces acting on a body will add, in the vector sense. Without that much of basic principles, you could not begin to answer the question you asked in the OP. You're still lacking in quite a few things you would need to know to solve the equations of motion for the pendulum before, during, and after the acceleration of the car.That's all you need to know.

I already explained it 27.5 times, James, what more do you want? Evidence? I'm not in the manufacturing business, I'm in the theoretical development department.
I already responded, James.
What more information do you want?
The way I see it (because after all, perception is reality) you have suffered the agony of defeat and you have no choice but to turn to negative comments. I'm not interested in playing your personal attack game.
Except that Motor Daddy's world view is demonstrably wrong. IF this were just a disagreement about equally valid theories it would be different.
I notice that the pseudoscience types all seem to come to each other's aid and yet they all disagree. Each has their own weird ideas. I attribute this to an attitude that all ideas are equal. An idea that is popular in early grades of public school, but when we get to the real adult world it is completely false. All ideas are not equally valid or even equally acceptable. Somebody earlier said that the science advocates were guilty of "argument of appeal to authority". When the argument is contrary to overwhelming evidence it is wrong. There is no middle ground. Motor Daddy is wrong and there is not even a minuscule possibility he is correct. His ideas do not meet any level of validity. It is time we all abandon this notion that all ideas are equal, that all arguments are equal and that everyone deserves a hearing. If I needed the advice of a doctor I am not going to ask the guy that changes the oil in my car about my condition. Nor would you.
There are no absolutes in spacetime. Ten minutes of research will show that. Sticking to wrong views is what most of this thread is about.I don't for a moment think that MD is intellectually dishonest or evasive for sticking to his views.
That doesn't change the fact that there is no absolute motion.there can be no cast-iron guarantee that the cutting-edge science of today will not represent the discredited alchemy of tomorrow
Anyone who declares that there is absolute motion is at the end of quite a bit of knowledge. Similarly, anyone who dismisses the world body of knowledge as something . . . unreliable? unproven? . . . has already reached the end of that road, insofar as their personal journey in science is concerned.Or have we reached that unique position today, where we are finally at the end of all knowledge ?
