The speed at which you travel has a direct bearing on the time required.
Ignoring relativistic effects, estimates of the solution may be derived by direct application of the Newtonian laws
of motion, somewhat as follows, to wit:
Speed . . . . . . . . . . . . . . Time required to travel 4 light-hours
c (light speed) . . . . . . . . . 4 hours
0.001c (300,000 m/s). . . . 40 hours
0.000001c (300 m/s) . . . . 400 hours
60 mph. . . . . . . . . . . . . . . 5,100 years
The unit of distance called "light year" is equal to about 9.46 x 105 m, and is, according to its name, the distance covered by the light during a period of one Earth year. Therefore, it would take 4 years to travel 4 light years, or about 1461 days.
According to who - the person travelling or some one just watching from a fixed point. For the person travelling - no time elapses, as they are travelling at the speed of light.
Tricky one :-) 45 Billion years.
That depends on the speed at which one is traveling.
900 billion years - if you travel near the speed of light. If you travel at any slower speed, it will take longer of course. But do some reading on time dilation - if the traveller travels at a speed very near the speed of light, from his point of view it will take much less time.900 billion years - if you travel near the speed of light.

You would travel northeast.
You would be traveling northwest.
As with any other "how long does it take" question, that would depend on the speed. At the speed of light (which we CAN NOT even approach with current technology) it would take 100 years. At slower speeds, it would obviously take much longer.
No such thing would happen. Matter cannot reach the speed of light, only massless things can (and they cannot travel at any other speed than the speed of light).
It really depends on your speed. If you were traveling at the speed of light, it would take 600 years. 600 light years equals 3,527,175,223,910,165 miles. So divide that by the speed you would be traveling to get the length of time it would take you.

The speed of light is constant. It is 671,000,000 mph.
probably not... at least not with our current technology traveling at the speed of light could also cause problems, everyone would be creating sonic booms....
Nothing with a rest mass can travel at exactly the speed of light, it would take an infinite amount of energy. Light can travel at that speed because it has zero rest mass. Earlier Answer below So far, we don't know if a human can travel at lightspeed. However, it's easier to travel at the speed of light than to travel through time. New Answer: The problem I always had with the term light speed is that speed is relative. We may be traveling close to the speed of light right now in relation to some other object in the universe.
To an outside observer a person traveling at the speed of light would be frozen in time. To the person traveling at the speed of light, things would seem normal.
It is not possible for any physical object to accelerated to the speed of light. But in one particular extreme it is possible to slow the speed of light according to the Bose-Einstein Condensate. The question better stated would be "Would an independent observer see light emanating from a source that is traveling backwards at the speed of light?" Yes. Light always travels at the same rate. No matter how fast you are traveling, any light that you emit will always travel at a constant rate. (note that it's not possible for a physical object to actually travel at the speed of light in a vacuum).
The speed of light doesn't travel at all. It just lays there, typicallyon a printed page in a book.If an object is traveling at the speed of light, however, then it's acompletely different story. Such an object would cover 1 quintillionmiles in only 170,108 years (rounded).
In theory you would not see them because there is no way of the light getting to you because for that to happen you would need to travel slower than the light or the light would have to be coming from the opposed direction
approx 333 seconds, 5 1/2 minutes
It might not be visible to the naked human eye, but when it wasn't traveling at the speed of light it would be visible. So no, it would not be literally invisible. Traveling faster than the speed of light would merely provide the illusion of invisiblity. If you were trying to detect it using visible light reflected from the rear as it moved away from you, yes, it would be invisible. But that condition is impossible, since faster-than-light travel is impossible. If it were possible, then light wouldn't be light, and time wouldn't be time and, very likely, the Universe simply would not be.
