‘Stellar’ black holes kind when large stars collapse below their very own gravity on the finish of their lives.
We all know {that a} star will need to have an preliminary mass of between 15–20 photo voltaic lots to be able to collapse and kind a stellar black gap.
We even have a fairly good thought of the distribution of stellar lots within the Milky Approach.
undefined
These two information inform us that about one in 1,000 stars has the potential to turn into a black gap.
An estimate of the variety of stars within the Milky Approach, 100 billion stars, then implies there could possibly be as much as 100 million stellar black holes within the Milky Approach.
This text is a solution to the query (requested by [Aled Weaver, Wigan]) ‘What number of black holes are there within the Milky Approach?’
