Er, no they haven't.
Er, I think I have read them all, and Err, yes they do all basically agree.
As one who appears to often misinterpret articles/papers etc, when they fail to support your model, you obviously have done the same here.
Er, no they haven't.
No.Do you have a paper published explaining why a pencil falls down or not?
Yes.Can I assume you've had more than five years to write one?
No. But guys like Albrecht Giese explain it.Do you explain it in your book
I don't know. Maybe tashja could ask the profs why a pencil falls down.and if so, why hasn't the physics community caught on yet?
I can address these questions, and you should believe what I say because I back it up with references to Einstein and the evidence.If you can't address these questions, why should anyone believe anything you say.
No they don't. And lying about it does you no favours.paddoboy said:Er, I think I have read them all, and Err, yes they do all basically agree.

Prof. Lovelace:
Please accept my apologies for the delay in my reply.
Do two photons traveling side-by-side, only one micron apart, attract each other via their gravitational interaction (by their warp of space time) by their ("stress-energy tensor) or any other terms you prefer?
Interesting questions!
Einstein's theory of gravity says that gravity is curved space and time. Normally, mass is the dominant thing that causes this curvature, but other things, like pressure, can also cause curvature. More precisely, the "stress energy tensor," which includes energy, momentum, and stress (pressures and shears), determines the curvature of spacetime. Photons have no mass, but they do carry energy and momentum. Electromagentic fields also have stress (pressures and shears). All of these are ingredients in the "stress energy tensor," so they must have gravitational effects. A quick web search turned up a paper that looks into this:
http://journals.aps.org/pr/abstract/10.1103/PhysRev.37.602
They find that light does interact with light gravitationally, but not necessarily in precisely the way you would expect from Newtonian physics.
Assuming that you are saying {with (1)} that photons do mutually attract, is it conceptually possible that a Black Hole could have no rest mass as it is only "zillions of photons" orbiting the center "like a swarm of bees" due to the mutual warping of space about that point?
I don't think you could use this idea to say a black hole might have no rest mass, though. A black hole's horizon has a size that is proportional to the hole's rest mass. A black hole with zero rest mass would have zero size.
A black hole's rest mass can actually be measured. For instance, by looking carefully at the orbit of stars moving around the hole, you can infer the hole's mass. This is a way to measure the mass of the hole in our galaxy's center.
Another trouble is that relativity says that all objects with zero rest mass move at the speed of light, while all objects with nonzero rest mass move at speeds less than the speed of light. So if you think of a black hole as a point particle (by looking at it from very far away), it has to have rest mass if it's moving slower than light.
So I don't see a way around black holes having rest mass. However, it's an open question precisely what happens inside a black hole. We don't have a full theory of quantum gravity yet, so exactly what's going on inside.

...plague proportions wherever you chose to spread your fairy tails.
Man, curb your spellchecker!
Woah! I only mentioned in the passed decade, but Einstein is in the century territory. Surely everyone must be really really dumb at this point not to "get it".
Do you have faith in humanity? Can you teach us the great wisdom of Einstein?
And no. You didn't address the questions to any truthful amount.
As great as the great man was, he was not infallible. But more to the point, your reputation for misinterpreting, mangling, and misunderstanding what others have said is observed in plague proportions wherever you chose to spread your fairy tails.
Read my previous post, and of course we will both be judged by our peers on this forum.
I'm only too happy to be met with critique criticism and disagreement. But note that these are not my ideas, I'm referring to Einstein, and I'm not happy to be met with unmoderated abuse from people who say things like misinterpreting mangling misunderstanding dumb not truthful etc in order to dismiss what Einstein actually said and trash the thread. Please read this page of the thread, note how it is being deliberately trashed, and moderate accordingly.Farsight... just a bit of advice...
are hardly "trolling"... in fact, both make good points. Einstein was not infallible, nor are his ideas necessarily the "only truth".
If you are looking for a place to soapbox your ideas without critique, criticism, or disagreement... then this is not the forum you are looking for.
Sure, because you seem to like the attention and you like the opportunity to declare yourself an expert and seem smart. You seemingly don't like having to do the actual work to produce evidence for your claims, since in your history on the internet you have never done a physics problem with any details, even when you make specific claims about how physicists do specific problems (e.g., your dark matter claims).I'm only too happy to be met with critique criticism and disagreement.
Yes, you "refer" to Einstein, but it is clearly a matter of contention as to whether or not your claims are the claims of Einstein. Since you never discuss Einstein's actual physics and it seems that you cannot do physics, it seems unlikely that your claims are Einstein's claims.But note that these are not my ideas, I'm referring to Einstein,
It is not abuse to ask you for some sort of evidence that your claims are true. For example, you claim that inhomogeneous space is the key to understanding gravity, yet you never produce an example of how we could use inhomogeneous space in a physics problem involving gravity. Additionally, when you have not told the truth, it is not abuse to point out that you didn't tell the truth. When you provide a citation that makes the opposite claim of what you say the citation is saying, it is not abuse to point out that you are producing, at best, a misinterpretation of that source.and I'm not happy to be met with unmoderated abuse from people who say things like misinterpreting mangling misunderstanding dumb not truthful etc in order to dismiss what Einstein actually said and trash the thread.
This is mendacious, I've referred repeatedly to Einstein's Leyden Address where he said "empty space" in its physical relation is neither homogeneous nor isotropic, and I've referred to Inhomogeneous Vacuum: An Alternative Interpretation of Curved Spacetime, I've responded repeatedly to PhysBang's requests to explain how inhomogeneous space results in gravity, such as here. I have told the truth, I haven't provided a citation that makes the opposite claim of what I say the citation is saying, and I don't dodge hard questions.PhysBang said:...It is not abuse to ask you for some sort of evidence that your claims are true. For example, you claim that inhomogeneous space is the key to understanding gravity, yet you never produce an example of how we could use inhomogeneous space in a physics problem involving gravity...
What I discuss is physics, PhysBang's diatribe is not.PhysBang said:...If we cannot use inhomogeneous space to do this, then it is not physics.
But I do understand what Einstein was talking about with the inhomogeneous space, and so can you, because you too can read where Bez says gravity is not really a 'force', but just a manifestation of the curvature of spacetime. Note: not the curvature of space, but of spacetime. The distinction is crucial. So the space in the room you're in isn't curved. So what is it? Inhomogeneous.Referring to someone is not the same as citing/quoting/understanding them nor their ideas...
