However, GRBs are rare in galaxies like the Milky Way.
然而,像银河系这样的星系中,伽马射线爆很少发生。
The question is why only a small fraction of supernovae produce GRBs.
问题是,为何只有一小部份的超新星会产生GRB ?
GRBs, but most agree that some kind of explosion is involved.

The caveat for Swift is that it sees stars at the ends of their lives, and there has to be a question mark over whether the redshift 8-10 era would be sufficiently mature to produce GRBs.
