From Philip Le Riche Harpenden, Hertfordshire, UK
I always understood that time grinds to a halt at a black hole’s event horizon. If so, it is surely nonsensical to ask what is inside a black hole, and by implication, whether at this moment it contains a singularity.
So if I were to fly my spaceship across the event horizon of a black hole, I’d see the entire future of the universe play out in my wing mirrors before (if ever) hitting a singularity!
