Black Hole Thought

[Physik]

I don't know much about the subject of BlackHoles, but could someone tell me if this is correct: "As a BlackHole sucks in an object the mass will either disappear or reduce significantly."

":" is a ratio

Object approaches Speed of Light : Positive Mass (or build up of mass as it approaches speed of light) = BlackHole's gravity (Slows object down) : Negative Mass (Mass is going away)

Anything falling into a black hole simply increases the mass of the black hole.

[Physik]

No no, I'm asking if the object falling into the black hole will decrease in mass.

EDIT: or does the object just keep it's mass and fall into the blackhole?

[Chronos]

Correct. No mass loss. The relativistic mass increases due to gravitational acceleration

Anything falling into a black hole simply increases the mass of the black hole.
When a particle pair drop into black hole, the positive energy will turn into negative energy and vice-versa due to the strong gravity force of black hole. Thus, the negative energy drop into the black hole and decrease the energy of the black hole. According to E=mc^2, the mass of black hole will decrease, not increase. The mass of the particle drop in to the black hole simply release into space through radiation. In another terms, it is something like recycle.

That is a dog of a different color. The quantum mechanical explanation for Hawking radiation is what you are describing.
