Question

Do black dwarfs exist in the Milky Way?

Answer 1

Not yet

Explanation:

For a black dwarf to form by the cooling of a white dwarf is estimated to require about `10^15` years.

The universe has only been around for about `13.8` billion years. That's `1.38 xx 10^10` years.

So it will take until about `70000` times the current age of the universe for the first black dwarfs to form.
