The problem did not specify that the ant is immortal. If it would take 8.547e+35 years then the answer is clearly no, the ant will not reach the other end. Ants don't generally live that long. ;P

It is possible. The first beta of .NET 1.0 was released in 2000.

Yes, but, as Professor Hawking pointed out, it would not seem like six years to the astronauts making the journey. This is because of the effects of special relativity. As velocity increases, the passage of time slows. This has been verified by experimentation. At near the speed of light time would pass so slowly that what we on earth would measure as six years the astronauts would only measure as a matter of months or weeks or maybe even days depending on how long it took to reach maximum velocity.
