How many year does it take for heat generated in the sun core to reach it outer layer,the photosphere?

';the typical time taken for radiation to diffuse from the centre and escape from the sun is about 50,000 years.';





It's a random-walk problem. Photons are continually scattered, absorbed and emitted by particles in the sun.How many year does it take for heat generated in the sun core to reach it outer layer,the photosphere?
i dunno, but someone up there ^ ^ ^ said it was 4-5 mins to get the light to the earth, its just over 8 minutes.How many year does it take for heat generated in the sun core to reach it outer layer,the photosphere?
I haven't a clue when the heat reaches it's outer layer.
About one million years. Really.
From thousands to millions of years. Even though the photos are traveling at the speed of light (a speed which would allow them to escape in a second or less if they were allowed to travel directly out), they smack into each other in an endless game of bumper cars on the way out.





Update:


Once they get to the photosphere it's fair game, and they go screaming out (check out pictures of the sun's corona). I think it's around 6 - 8 minutes before earth gets a bath :P.


(you can find this time yourself: google distance of earth from sun, divide by 300,000 km/sec).
it takes light (which heats the planet ) about 4-5 minutes to reach earth from memory
I think you will find that heat in itself is not something that can be measured. Only it's effect on something else. As the sun is always roughly the same temperature there is no way you would ever be able to tell how long it took for the waste product of heat, caused by the reaction in the core, to reach the outside layer. It is simply an impossible calculation.
