The question about `Climbing out of a Black Hole?` was meant to be rhetorical, so I was not really looking for a confirmation of the answer – No. In part, this was why I made reference to an earlier discussion on the implications of the Schwarzschild Metric. Clearly, your footnote about...

First, let me address the concerns of `pervect`. The intention of my original post was simply to raise a question; it was not intended to be read as a speculative theory. It was based on the standard response to the twin paradox, but extrapolated to the triplet scenario in order to highlight an...

This thread is another extending from the `Schwarzschild Metric` and `Climbing out of a Black Hole`. I hope the members of the physics forum will not object to me testing out some ideas against their wider knowledge in this subject area. Anybody reading about relativity bumps into the Twin...

By way of explanation, I am on a learning curve as far as relativity is concerned, but then this might be true for everybody. Some of my questions might appear off the wall, but I am not interested in learning about this subject by rote, hence the questions. This thread is an extension of...

Based on the helpful feedback to my original question about the effects of both general & special relativity, I wanted to try and outline my current understanding of the implications of Schwarzschild metric. Of course, I would still welcome any clarification or corrections on any issue. 1)...

Ich, many thanks for some excellent feedback. Basically I agree that the special relativity effect is built into the Schwarzshild metric, which in the GPS example comes from the angular velocity term associated the orbital velocity of the satellite. Of course, while it is built into the metric...

Thanks to both Ich & Mentz114 for taking the trouble to help me with my questions. It is much appreciated. I realize that an objects falling towards the event horizon can be subject to different interpretations depending on the frame of reference, e.g. distant observer, shell observations at...

Thanks to both A.T. and Mentz114 for their input. AT: An interesting point about space versus length contraction. Certainly, within special relativity the emphasis is on length contraction, but the implication is still that the forward length is contracted thereby maintaining the invariance...

Hi, I am new to this forum so I apologise if a similar thread already exists. I am trying to resolve the implications on space and time as you approach a black hole event horizon with respect a distant observer and an onboard observer. My issue relates to combining the effects of both...
