However, what I think you really meant is a thought experiment which has been around for as long as relativity. As you approach the speed of light, light approaching you from the front gets blue shifted further and further... ultimately you are speeding into a wall of gamma rays.
Likewise the light approaching from behind gets more and more redshifted, so behind you appears a very nearly dark void that appears to be very close to absolute zero in temperature.
To the sides, you would see the effects of length contraction as things would appear shortened in the direction you are travelling.
Extrapolating, you could reasonably argue that if you were able to travel at c and also able to experience time and perceive at c, you would see a hemisphere of gamma rays in front, a cold (absolute zero) hemisphere behind you and the entire visible universe compressed into the plane between the two.

I understand and comprehend all that you have said here .... a ' plausible ' answer to the question..... but I don't see what is ' nonsense ' about it.
Maybe others have a different ' perspective ' on this and wish to contribute.
