Following @Ibix's clarification in #28, it seems that I misinterpreted his meaning. -
Dale replied to the thread B How can a black hole absorb matter?.Why? The existence of any finite ##\Delta \tau## is sufficient. @Ibix argument doesn’t rely on there being an upper bound.
-
The coordinates that I was talking about should cover the horizon (and possibly the interior). How else can the the metric be...
-
I would observe that there are two distinct periods in the history of a distant observer of a stellar collapse: the period where the...

Dale reacted to Greg Bernhardt's post in the thread Insights Relativator (Circular Slide-Rule): Simulated with Desmos - Insight with
Like.
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. The Relativator was sold by (as printed)... -
Dale replied to the thread B How can a black hole absorb matter?.That is only a small part of the trick, not even close to the whole trick. Other parts of the trick include 1) we can use any...

Consider a case of a collapsing progenitor, say. Suppose we are given an arbitrary event on the world-tube of an eternally-external...
-
But you are still using Newtonian formulae, which means you accept the principle of relativity. So you are not testing the principle of...

Dale reacted to Asaad-Hamad's post in the thread I Can this experiment break Lorentz symmetry? with
Skeptical.
That is the critical point, my argument hinges on the partitioning of energy into 'spark' and 'passive' components. The spark energy... -
Dale reacted to Cerenkov's post in the thread A Could gamma-ray bursts have an intragalactic origin? with Like.
Then, if you found nothing to support your claim and if you rely on others to clarify the issue, your claim (that absorption is...

Dale reacted to Cerenkov's post in the thread A Could gamma-ray bursts have an intragalactic origin? with Like.
There are two problems with your reply, Line_112. The first is that you still haven't cited any values for gamma ray absorption by the...

Dale reacted to Bandersnatch's post in the thread A Could gamma-ray bursts have an intragalactic origin? with Like.
But to what extent? Attenuation by 10 or even 90% doesn't preclude detection. It's not all or nothing. You can't just hand-wave it and...

Dale replied to the thread B How can a black hole absorb matter?.This is too broad of a statement. The correct statement would be that in Schwarzschild coordinates the coordinate time asymptotically...

A surface with at least one null tangent vector everywhere on it. Light cones are another example. In flat spacetime, at any instant...

Very good points, thanks all of you for your comments. I know it took time out of your days to respond back to me, and I appreciate it...
