Agreed.
I said the tensile strength can be arbitrarily high, not infinite. It seems like you’re suggesting that the ability of the tidal force to break an object is unaffected by its tensile strength. But everything I’ve read says the opposite.
I’m not sure I can prove that. But it doesn’t...
How is this different from saying that there’s no such thing as a freely falling object? Doesn’t this apply to even a dust particle? Even a dust particle is made up of interacting particles.
You’re suggesting that any object floating in space rips apart due to forces other than tidal forces...
I don’t disagree with anything in your post. But how does it show the problem with my argument? The rod spans the horizon; the horizon is somewhere along the rod. When you’re grazing Alpha Centauri, its distance from you does not depend on your velocity; it’s zero. And you’re at Alpha Centauri...
Assuming for the sake of argument it implied that, how does it answer the key question: how can GR be self-consistent? More on this below.
The rod I’m talking about is freely falling. By the definition of “freely falling object”, no forces except gravity are acting on the rod. Then if the rod...
For any part of the rod to fall inward through the horizon, the rod must first break. But that’s the question, whether or not the rod breaks. If you’re talking about one of the cloud of particles that forms the black hole, I don’t see why it would need to be close to a particle of the rod that...
Thanks so much for that great info pervect!
But if MTW are right, then how is GR valid? Let a freely falling rod be escaping to r=infinity radially as it travels through a group of particles falling toward one another to eventually form a black hole, when a horizon forms along the rod so that...
I doubt this. Can you provide a reference please? What about for a freely falling observer who is just above the horizon and escaping to r=infinity (i.e. in free fall and moving away from the black hole)? Is the tidal force for such an observer independent of her velocity?
I spent a few years writing software to predict future price movements. It shows that stock price movements are predictable at least one day in advance, to a degree at which only a brokerage house could (greatly) profit. The transaction costs must be very small (like 0.05%) to profit. I didn't...
Disagreement with generally accepted viewpoints is not allowed here. If anyone wants polite discussion with me, email me by clicking on my alias on the paper, or google for an open-minded forum.
Nope. My text doesn't reference two clocks. Only one clock at a fixed position in the rocket is needed. The clock can be infinitesimally small.
This thread can be locked now.
Certainly a reasonable assumption. If one is told by a mod to go ahead and post a question, no reasonable person would expect the thread to be summarily closed.
Oh yes, if they give up on it, then I must be wrong--that's logical. This is a good example of what I'm talking about here. PF is...
The difference is, what I throw out I support with evidence.
It is obvious to any reasonable person that the thread did not deteriorate.
Not becoming, but was, in the form of a question. Just as Tom told me I could do.
Every objection was in the process of being resolved with reason...
You aren't fit to be a mod, with a comment like that.
Had I known the thread might be summarily closed at some point, I would not have started it. Common human decency calls for notice of that possibility when one is told they can start the thread.
They expressed their disagreement. The...
About this post:
Wow, your mods are piece of work. Tom Mattson told me I could post a question in the forum, after I told him that I disagreed with the off-base reasons for a rejection of a paper I submittted to the IR forum.
I conclude:
- Your mods need better communication among...
See post 79 and post 81. The coordinate system of an accelerated observer is immaterial here, because the observers (crew and observer on the planet) can measure the distance to the buoy (either passed in the case of the crew, or thrown up in the case of the observer on the planet) in an...
