kalau gitu, kita harus minta bantuan Starfleet segera utk mendeploy Red Matter.
I don't want to be NERO.
btw, ini lanjutannya:
1. It sounds scary stuff. And the astronomers' news release suggest it will
happen "soon". But I contacted the lead researcher, Dr Ed Sion, and he told me:
"At the accretion rate we derived, the white dwarf in T Pyxidis will reach the
Chandrasekhar Limit in ten million years. I hope this alleviates any worry by
readers."

2. It seems that Sion had used data for a far more deadly gamma-ray burst (GRB)
exploding 3,260 light-years from Earth, not a supernova. T Pyxidis certainly
isn't expected to produce a GRB. (Gamma-ray bursts are thought to only be
generated by a massive star that has reached the end of its life as a
Wolf-Rayet star collapsing under its own gravitational attraction.)
"A supernova would have to be 10 times closer [to Earth] to do the damage
described," Ray informed me via email.
