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

As long as the light remains in the motor oil, nothing happens to its speed.
It moves at a slower speed!
Travelling through a medium that is optically less dense. Vacuum is best.
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.

None or Infinity. What speed are you travelling? Are we walking or travelling the speed of light? Temporal distance is entirely dependant on velocities.
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.

Unless I am travelling in the speed of light, yes.

curiosity... is the correct answer
The velocity of light is greatest when travelling through a vacuum. When travelling through something else, a glass material say, then its velocity is slower. The refractive index is the ratio of the speed of light in a vacuum to the speed of light in that substance. For example light travels in a vacuum about 1.3 times as fast as in water, so we say water has a refractive index of 1.3. And it is likely that the velocity in the glass will be different at different wavelengths of light.
