I can't figure out how to use the quote buttons, but all the quotes are from JesseM in the following. "But this limit seems unphysical, since no massive observer can be even instantaneously at rest relative to the event horizon in a local sense, as the velocity of the event horizon is c as...

Further discussion on the points raised by JesseM in post #7. First, I think there may be some confusion of acronyms. In my first post, "ffo" stands for "far-field observer" (i.e., us), and not "free-falling observer". In addition, the observer near the horizon my remarks referred to was...

Thanks for replying. Is it not the case that the ffo tells time by the Schwarzschild clock? In any case, it seems to me that the red-shift/blue shift argument still raises a problem. Is it not true that the red-shift of light from the momentarily stationary observer near the horizon, as...

I think this subject may have been discussed here already; please point to the thread if so. I am unable to understand how Black Holes can form within the lifetime of the universe. If nothing can cross an event horizon in finite time, then it seems clear that the horizon can't form (at...
