What? Any reading material on the last part?
- jerf 4y agoI don't have a specific link. But the larger the black hole, the lesser the tidal forces at the event horizon. Tidal forces are created by gravity gradients, the differences, and the differences become less extreme as the black hole sizes up. You can see it just by thinking about how the gravity field changes around an object as it gets larger; think about where the 1G line as you make the Earth denser and denser, and note how quickly the field is changing at that point. Hypothetically, a large black hole would permit you to actually survive entry into the event horizon. It's still hypothetical because the environment around any such black hole in the current era is still far too violent for you to get that close, and it will be for cosmologically-meaningful periods of time.
