If I were able to travel at the speed of light, I would arrive at Rigel instantaneously, from my point of view. It would seem longer to you as an observer on earth. Rigel is estimated to be between 700 and 900 light years from earth, so between 700 and 900 years would elapse on earth before my instantaneous arrive there.
No - you would be stopped BEFORE you reach the speed of light, by your increasing mass (among other things). As your speed approaches the speed of light, your mass would approach infinity, and it would require an infinite energy to actually achieve the speed of light.Note that the "speed of light" is not really about light. It is a speed limit of our Universe; some have described it as the "speed of causality".
Technically, this question is flawed, since one of the most important rules in physics is that no matter that has mass can travel at or above the speed of light (this is why scientists argue that traveling back in time is impossible) you would need extreme force and very special circumstances. However, for hypothetical purposes, lets say that you are able to reach the speed of light. When you turn on your headlights, nothing out of the ordinary will happen. You will merely see the light speed away from you at the speed of light. It would be the same as if you were standing still in your car and turned on the headlights. This is one of the must incredible things about the speed of light (c) - it is constant for everybody. Even if you were an onlooker and you somehow saw the car go by, it wouldn't happen at twice the speed of light, it would still happen at regular (c). Going further, since the speed of the light viewed doesn't change, then what does? The time. If you are able to go near the speed of light (like .9999 times), time would go more slowly for you (compared to normal, but you wouldn't notice anything. If you look at the outside world, time would appear to be traveling faster. For example, going .9999 times the speed of light, traveling for one year would actually be 70 years for anyone else. If you were able to reach the speed of light, you will have esentially stopped time, and if you were able to go faster than the speed of light, there would be an inertial frame of reference in which you would be travelling back in time. This is actually a very touchy subject, i highly recommend reading more about it. There are some very interesting videos and books by Stephen Hawking on youtube that you can watch, both about light, relativity, time travel, all of that.
You cannot go at or faster than the speed of light. Let's say your bubble was going 2 mph less than the speed of light. The way relativity works, you could ride your bike at any speed humanly possible, from your point of view. But your time is slowed down, so from an outside observer, you appear to only move slightly faster (still less than light speed). And if you turn on that flashlight, it will go away from you apparently at light speed, but the outside observer will also see it moving at light speed. It is tricky when you first encounter this.
at the speed of light, a little over 8 minuets.
That would depend what it enters from. If the light is transitioning from air to water,its speed decreases. If it's going from jello to water, its speed increases.

if you are going the speed of light, it would take 1 year.
At a speed 212 000 kilometers per second you have a relativistic gamma of 1.41, and you will time 365 days of travel when travelling one light-year. You would think that effectively you were going at light-speed! An observer would see you going slower though, and would time your trip to over 516 days.
Since no object with mass can reach the speed of light -- such an object can only approach that speed -- the question is meaningless.
It could
You CAN'T go AT the speed of light. In theory, it might be possible to travel CLOSE to the speed of light; in which case, the answer is yes - since time passes much slower for you. From your point of view, the distances in the direction you are traveling would get much shorter.
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.
I'd imagine it would go the speed of light because time would slow down to make sure the light wouldn't go faster than the speed of light.
You cannot even travel at the speed of light. So forget about going faster.
speed sensor is out or is going out. your speedometer is out too right?

The speed of light from the flashlight would still be the speed of light, which is a constant value in a vacuum regardless of the observer's motion. This is one of the fundamental principles of Einstein's theory of relativity.
