: : : is there anyone who knows an equation to find the amount of energy given off by a black hole. ex: old faithful

: : If anyone does that would be cool. I only know there is some. I don't think there is a formula, but I know there is a chance and I'm sure someone out there could make up one. If I knew HOW energy could possible leave a black hole I'd LOVE to know.

: there is such a thing as energy leaving a black : hole. in theory this energy is knwon as a white hole. : also NASA discovered a black hole "old faithful" this year : that gave off energy it had taken in every 30 minutes : i believe. if you do find someone that has such eqautions please : inform me. this info is essential to my grade.

I don't have any equations, but I can offer this idea. Nothing we know of is eternal, so in the case of energy and black "holes"- what goes in, must come out. I place holes in parenthesis because this is a misconception. Just because the forces ar incredibly strong inside a black hole it doesn't mean that matter, or energy are vanishing through some portal. They are being released in some form perpendicular to the accretion disc. I think a better term for black holes would be black stars, since they are not infinitely anything.
