If the Sun were replaced by a black hole of the same mass, would Earth be pulled in?
No. Earth would remain in nearly the same orbit. Sunlight already on its way would keep arriving for about eight minutes—then the sky would go dark.
A black hole is not a cosmic vacuum cleaner. At the same distance, equal mass means similar gravity. The event horizon is where escape becomes impossible, even for light.
