![]() But thanks for the clarification! Actually though, in a few posts before post #43, when I quoted Grey and Tensor, which was about the 'light in it's own frame' Singularity, and then you found their replys, which forced me to defend, and I was then warned by Captain Swoop about moving into ATM territory, after which I simply reverted back to, and stayed on, the very mainstream....light is Constant at 186,282.4 mps and has a specified distance and specified travel time as seen in 'Earths Frame' for our Local Neighborhood...............which is 100% Irrefutable!!! SO, once again, the 'second truth' Must be a "Problem"...because... Quote:
Just asking KenG to respond to my posts rather than play Jeff and I against one another should not have closed that thread (But oh well, so be it), as we were just getting to a point where some things could have been remedied. But, I will tell you this...one of the main problems is...thinking that the 'at rest observer of SR' is equal to the "Earth Frame Observer" is NOT correct!!! And even agreeing to Alpha Centauri being ~ 4 light years distant is NOT even allowed in Relativity...you are not doing Relativity when agreeing to that! There are definitely some other things KenG did in that thread that I will be addressing in one form or another... ![]() But, in that thread I very purposely and carefully made sure that 1. I stayed in Earths Frame. 2. just used the Astronomy definition of light being Constant "c". 3. Tried to keep the whole conversation about Local known distances with no expansion of the universe.........BUT KenG used every trick in the book to use "Distance then" VS "Distance Now" to have to be about Global considerations, no matter how many times, jeff and I told him we were talking about Local!!! But, in one of his last posts, when he asked jeff this.... Quote:
Which just shows how Utterly undefined it is, trying to do anything 'in light's own frame', because it is ALL definitions in the division by 0 realm. He just made a "New" definition, that a person, without a spaceship, could travel Relavistically...and turn into more and more pure energy going from 0 to Infinity! [ETA: Also, just to clarify something, rather than open a new thread, Jeff Root was doing an excellent job in that thread............Until he made the mistake of putting himself on that train platform, and in the train!!!] And he also said...

BUT, all of this is irrelevent to what I am showing and defending in the first part of my post, which I stipulated right up front, and not one poster yet is even getting that.....they all want to start with... Realativity is already "Proven", which I pretty much expected. I toyed with just showing the very first part, and probably will have to do just that.

Actually it is these two in combination... So, here is the problem right here…A and B are both “Motionless” and he (Einstein, OR it may have been Lorentz before him) “Assumes” a full Lorentz Transform of A and B’s “Nows”, just because there is a light source halfway between them. That imaginary light source halfway between two observers is meaningless as pertaining to their “Nows”!!! In addition to that, since Einstein was working in an “Empty Universe”, there was “never” a distance established between A and B!!! So Relativity ends up with A and B, with the ability to be an “Infinity” away from each other

What I think that you are missing is that each observer can have a clock and a notebook, and that they are allowed to meet up later and say what they observed at various times. There is no need to pretend that there is a universal "now". SR very explicitly does not assume any universal now. It only ever asks "What time will observer A see on his own clock wen the light arrives from event X". This formulation entirely avoids the concept of a universal "now", which is important, as one of the key results is that there can exist no universal "now". |

How can a scientist, on their planet, in their Rest Frame, in Andromeda, sinc a T=0 time, with a scientist here on earth, in our "Earth Rest Frame"??? ETA: and even if there were a light source halfway between, those two scientists would still be ~2.5 million light years distant from each other, right?

Are you just saying that you did not know about these methods, or do you not think that they are valid? Or, a perfectly acceptable method is to stick a light bulb halfway between them, and turn it on. Both observers then set their clocks to zero when the flash arives. Why do you not think that this method works? It results in all observers in the same rest frame agreeing that the clocks are synchronised. Edited to add, I see that you rather sneakily changed the situation, and moved from asking how two observers in the same rest frame can synchronise, to asking how two observers in differing frames can synchronise. Of course, they can't, which is the whole point. If they are not at respect to one another, they are not going to agree on what "now" means. Can I take this shift to mean that you've noticed that synchronisation for stationary observers is not a problem? |

If you say that A and B are both motionless, you must specify in respect to what. In this case, they must both be in the same inertial frame of reference, and at rest in respect to it. This being the case, the Lorentz transformation does not apply. The Lorentz transformation applies only when one observer is in uniform motion in respect to the other. Your statement is therefore based on a false premise. Einstein's deliberations always involved one observer in non-accelerated motion to another, i.e. two different inertial frames of reference.

If a Super Nova went off in M31 right as the light bulb went off, halfway between M31 and us, how long would the SN photons take to reach us, and what would that mean to the two supposedly sinked clocks? Actually, if that SN goes off right when the scientist is M31 gets that light signal from the light bulb, his clock will read 0 and ours will read 0 too, and then it takes 2.5 million light years to get here, so our clock would read 2.5 million years later. So, what did it accomplish to even do that? Trying to make M31's time "now" equal our time "now" is meaningless.

You did not answer my question. I am talking about when to use the Lorentz transformations. I read your OP and am no wiser. You speak of both A and B being "motionless". Define "motionless". I said that this means both are in the exact same inertial frame of reference. And then the Lorentz transformations do not apply. What are you talking about? Please explain your position clearly.

Why are you doing this? If you are going to insist on using M31, then let's at least change the universe around and make it stationary with respect to us. You do understand, don't you, that you cannot argue about stationary observers otherwise? Now, you have just stated that we have an event at observer 1 when his clock reads zero. Observer two sees this when his clock reads 2.5 million years, but what of it? He notes this, notes that observer 1 is 2.5 million light years away, and concludes that observer one would have seen it when observer 1's clock read zero. Given that he knows that the clocks are synchronised, he can go further, and say that, for obserer 2, the supernova happened at T=0 also. Both observers agree that the supernova happened at T=0, on both of their clocks. How on earth does this invalidate any synchronisation? |

Russ,
I think I see where you are going with this. If I am not missreading all this you are trying to seperate Space and Time into two different mathmatical entities. However I need to point out that even if 2 objects were motionless (a violation of Conservation of energy in that Entropy is 100%) that they will percieve events of the other object delayed. Even if you go down to the Phlank scale, the smallest unit of Time is 1 and Distance is 1. Ergo it's impossible to get a division by 0 error in a lorenze transformation. It always takes some portion of time for information to travel some distance. Which is why it's called SpaceTime. I don't see how you can mathmatically seperate the two. Nor do I see how what your saying actualy invalidates Relativity. If anything what you are saying supports it. There is always a Time lag, even at small scales.

I am starting to suspect that RussT is not using "synchronise" to mean what everyone else means. sing words in a nonstandard way, and not defining the new meaning is all too common among proponents of ATM theories, and causes much confusion.
RussT, do you understand that having synchronised clocks does not mean that all observers will see the same time on their clocks when they observe an event? The fact that observer 1 sees event x at time t=Y1, and observer 2 sees the event at t=Y2, where Y1=/=Y2 does not mean that the clocks are unsynchronised. It seems very likely now, I think, that you don't understand what physicists mean when they say synchronised, and that you are arguing against your own misunderstanding. Do you have a physics degree? This question is not relative to your arguments, but probably is relative to your understanding of the mainstream view, so I think it is acceptable when we are examining whether you have mixed up the meaning of terms. |

This basic thought experiment goes way back to Maxwell in the mid to late 19th Century. Basically A and B are on the same x axis. So the distance by which they are separated is along that x axis. The light source is not “halfway between” A and B. The light source is at A and a mirror is at B, which reflects the light back to A. This was also the basis of the Michelson/Morley experiment. The statement Lorentz made about it is contained in his 1895 book. A few pages of that book were translated and published in the early and later copies of the book “The Principle of Relativity”, here: http://i40.tinypic.com/n4jol0.jpg The basic principle would be like two guys riding on an open flatcar on a train. With the train stopped in still air, a sound “beep” traveling from A to B would take the same amount of time to go from A to B as a reflected sound “beep” would take to go from B to A. But if the train is moving, and B is at the front end of the flatcar, the sound of the “beep” will take slightly longer to get from A to B than it would take to get from B to A, because it is the air that regulates the speed of the sound “beep”, and the air is stationary with the embankment, while the flatcar is moving through it. In the Michelson/Morley and Lorentz thought experiments, the “ether” took the place of “the air” and the light beam was “the sound beep”. The “ether” was supposed to be universally stationary as A and B moved through it, along the x axis. The "ether" was supposed to regulate the speed of the light. Einstein based his 1905 theory on Lorentz’s 1895 theory, but Einstein didn’t use an “ether”. |

By the Way...do you have a degree? Like you said though, it is all about the material being covered, and critical thinking....I agree!

Distances: then or now? Starting with Post #13... Second.......LOL, I didn't do this, mainstream science did this from the very beginning of figuring out that light was Constant at 186,282.4 mps.... From our very decidely mainstream view "Earth Rest Frame" does seperate Time and Space, better known as the specified distance light travels in specified amounts of time, depending on known distances!!! Relativity doesn't even recogonize the term "Light Year"

Okay.......here is the set up...
You and I are in the Utah Salt Flats, dead of night, no moonlight. We are 5000 feet (Nearly a mile) apart. Halfway between us is a light source. When the beam is switched on and both beams hit our belt, our clocks both register 0 Now, because our clocks are both saying 0 'simultaneously'... do you now believe that both of our "Nows" are together/simultaneous??? Just give a Yes or No answer!!!!!!!!! Don't switch anything....no explanations!!!

RussT, stop the word games here, you clearly understand what is meant here and what Fortis is saying. In the rest frame of the light source and in which both observers are the two observers are synchronized.

Because obviously, NothernBoy thinks so, since he thinks this is legitimate in Relativity!
