it is impossible to fire a bullet a the speed of light
Travelling faster than the speed of light is not possible, therefore no galaxies have travelled or are travelling faster than the speed of light.
Photons begin their existence travelling at the speed of light, they do not "acquire" this speed.
* The speed of light in a vacuum, * The speed of sound,
Some of the furthest galaxies are believed to be "travelling" faster than the speed of light. They are not actually "travelling" faster than the speed of light, but creating space, faster than the speed of light.
No, not close at all.

bullet trains travel at 96.5 percent the speeed of a bullet No it doesn't. A bullet train does around 190mph normally and can reach 275mph. Depending on calibre, a rifle bullet travels at 1,500-2,000mph. So on average, a bullet train travelling at normal speed travels at between 9.5 and 12.6% of the speed of a rifle bullet.
Not in the near future. Other galaxies are hundreds of thousands, or millions, of light-years away; travelling at the speed of light, it would thus take millions of years to travel to most galaxies; travelling at a lower speed would, of course, take longer.Not in the near future.

Probably not. Nothing travels faster than the speed of light.
None or Infinity. What speed are you travelling? Are we walking or travelling the speed of light? Temporal distance is entirely dependant on velocities.
Unless I am travelling in the speed of light, yes.
