Once the lightbulb has crossed the event horizon this is no longer true, all paths lead to the singularity, just as all paths for us lead into the future.Red Rule wrote:if said lightbulb were to fall towards the black hole, it's no stretch of the imagination to say that there would atleast 1 photon whose velocity vector is direcly opposite to the gravitational vector.

A photon that is emitted outside the event horizon in the right direction will escape, but it will lose energy, in the form of being redshifted. So your nice blue lightbulb will appear to become red as it approaches the black hole.

Well, what most people don't realise is this: Inside an event horizon there is no such thing as "outwards."
Once you have fallen inside, every direction is towards the singularity.
You have to travel backwards in time to get out.

You'd be in a closed universe, doomed to collapse to a singularity in finite time.

But the calculation for the Schwarzschild radius doesn't include dark energy/cosmological constant, which at such low densities becomes very relevant.
