if we reach the speed of light our mass start converting into energy according to the mass energy relation when a particle accelerated it must radiate energy. and therefore the mass convert into energy as the velocity increase . relative mass (at velocity =v)=mass/1-v(power2)/c(power2) relative mass is present mass of object at tht velocity. then mass at (rest present mass )c (power2) why it is impossible for a particle too have a speed of light
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.

Probably not. Nothing travels faster than the speed of light.

Yes. It depends on the refractive index of the medium through which the light is travelling.
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.
it is impossible to fire a bullet a the speed of light

You would see the other traing going by you at nearly the speed of light. This may seem counter-intuitive, but that's what happens. The speed of light is an immutable constant that does not care about your frame of reference. In the braydeon domain, nothing moves faster than the speed of light, regardless of frame of reference.
The light refracts due to the change in speed. The change in speed occurs because the light is travelling through a denser medium. So it will travel fastest through the air and slowest through the glass
radiation
Travelling faster than the speed of sound causes a loud noise called the sonic boom.
Probably not. Nothing travels faster than the speed of light.
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.

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.
