A lot of the technical details I added were intended merely for theThe words "blows up" are correct; the metric tensor, "in the usual
interested reader and are admittedly superfluous as Jack pointed out below.
However, I must reiterate, there are no physical effects that blow up at the
event horizon of a Schwarzchild black hole, at least in the usual physics
sense of the words "blow up", which I interpret as loose language for
diverging to infinity. That does not mean interesting things don't happen
at the event horizon, as several well known interesting things do occur at
the event horizon.
To be further superfluous and add one more item of technical detail.
The Ricci tensor, a measure of gravitational effects in a local region of
space, does not diverge at the event horizon of a Schwarzchild black hole.
