My personal guess is that they start from a few hundred solar masses, but that's a much more speculativebusiness.
布兰德福德说，“我个人猜想他们是从几百个太阳的质量开始的，但是这种想法太投机了。”

General Motors represented one end of the spectrum - our company was formed from the acquisition of many smaller companies in what was, 95 years ago, a highly speculativebusiness.
This introduces the risk that the business requirements would change before the application is put into production and that speculative services would be built and not used.
