Black holes are not stronger pullers just by being black holes
Claim in the list: Black holes do not “suck in” everything from far away: if the Sun were replaced by a black hole of the same mass, Earth would continue in its orbit.
Verification: Confirmed as an idealized gravitational example. At sufficient distance, the gravitational field of a spherically symmetric body is determined by its mass; compactness does not create extra “suction.” If the Sun were instantly replaced by a black hole of the same mass, Earth’s orbit would remain nearly unchanged. Sunlight and heat would disappear, however, making Earth uninhabitable. This is a hypothetical scenario, not a possible natural endpoint for the Sun at its present mass.
Conclusion: A same-mass black hole would not pull Earth in; its gravity at our distance would be practically unchanged, but sunlight and heat would be gone.
