Traveling from New York to Los Angeles at the speed of light would take 13 milliseconds. A nonstop flight on a jet would take about 5 hours 40 minutes.
it is impossible to fire a bullet a 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.

That, no matter who measured the speed of a beam of light, the result would be the same. In other words, someone travelling at 99% the speed of light would measure the same speed as someone standing still (all realtive to the light source).

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.
With current technology, that's not possible. At the speed of light, it would take you tens of thousands of years to leave our galaxy. The speed of light seems to be a speed limit in the Universe, and current technology is nowhere near travelling the speed of light.
I'm not even sure what this is supposed to mean. "Accessible" how?You can go into a black hole. You don't need "a vehicle travelling at near light speed" to do so (of course, if you're on Earth now and want to get to a black hole before you die, such a vehicle would probably be required, since all the ones we know about are at least tens of thousands of years away at any speed any Earth-built spacecraft has ever reached).You can't come out again. Period. Not in a vehicle travelling at "near light speed", not in a vehicle travelling AT light speed. The escape velocity for a black hole exceeds the speed of light in a vacuum.
You would have to be travelling faster than the speed of light in order to do this. And, theoretically speaking, this would be impossible to do.However, if you were possible to travel faster than the speed of light, you would need to be travelling 1.25x the speed of light (which is about 3.75 x 108 m/s2).
You cannot even travel at the speed of light. So forget about going faster.
Well, it takes 2,700 years for light to travel that far. Anything travelling at half light-speed would take 5,400 years. At 1/4 light-speed, it would take 10,800 years.
