Default How long does it take a white dwarf to be a brown dwarf?

A FIRST GRADER WOULD DO BETTER THAN YOU, BEERT!

A few hundred trillion some odd years depending on how cool it needs
to get, such as cool enough to fast cook a well done stake in under a
minute.

Brown dwarfs(BDs) are actually failed little stars of insufficient
initial mass, such as a 10+ Mj item is perhaps just a very large and
hot gas giant planet, and otherwise not actually that of a puny
deficient star or much less that of any spent WD. *WD's eventually
become black dwarfs(BKDs).

"Barrow and Tipler estimate that it would take 10e15 years for a white
dwarf to cool to 5 K;[6] however, if weakly interacting massive
particles exist, it is possible that interactions with these particles
will keep some white dwarfs much warmer than this for approximately
10e25 years"

Brad save your **** for others.You know exactly what you are. TreBert
