Or it can have a collision that can create a fission neutron which then is tracked as well as the start of a fission which may be in a quite different place.
或者它有能够创造出一个裂变中子的碰撞,那能够追踪到一个裂变的开始,那可能是在一个很不同的位置。

You can have an elastic scattering collision where the neutron just essentially bounces off the uranium 235 atom and just continues on and it's possibly slowed down ever so slightly.
你可以得到一个弹性散射的碰撞，在那，原子就会反射，铀235原子，还会继续，那也可能会减慢一点。

The most likely explanation for GRB050709 is that it was produced by a collision of two neutron stars, or a neutron star and a black hole.
