Couldn't it evaporate into this size, or consume enough stars / other material to grow so large? Universe is young, but not so young this should be impossible

- semi-extrinsic 7y agoWrt. evaporation: no. Here is a handy online black hole calculator http://xaonon.dyndns.org/hawking/ http://xaonon.dyndns.org/hawking/ Punch in 130 solar masses, and you get a lifetime (before evaporation) of around 10^72 years. Age of the universe is 10^10 years, so evaporation is utterly negligible.
- tgb 7y agoThis was my first question, too. Disappointing that HN downvotes good-faith, on-topic questions.
