Infinity is a construct of mind, there are no infinities in Nature, not even time(which had a beginning and has experienced a finite duration), the Universe(ditto), distance of any sort(space also had a beginning and the Universe is finite), even the gravity of a BH does not go to infinity, there can always be a bigger BH with higher levels of gravity and greater density. I defy anyone to point to a single infinity outside of math(a tool that may or may not represent reality)or science(though the careful and accurate scientist will say "approaches infinity", not "goes to infinity" as it will never reach infinity, just like mass can never reach lightspeed). We say that things like the expansion of the Universe is infinite, but since it had a beginning and is currently of a finite(but unbounded)size, it isn't infinite, nor will it be infinite at any future point in time, therefore not infinite. We say infinite when we talk of processes that will continue indefinitely, but these processes had a beginning and are not infinite in the present, they will always be finite in every now, from now on.

Infinity is a concept, a concept constructed in the mind, not a reality. Time and Space are not infinite, they are finite and unbounded. As is everything they contain. Scientists know that if your calculations produce an infinity, something is wrong with your understanding, it is a warning sign that you have made a mistake, not that the infinity actually exists. Nature abhors infinities just like it abhors a truly empty vacuum, neither exists.

Nothing with mass can ever reach lightspeed, much less "crosses the speed of light without problem". Even the traveler never sees himself at superluminal speeds. Length contraction and time dilation occur at less than light speed

**to the traveler**, they do not affect distances or time in the rest of the Universe. The only thing that travels at light speed is the photon(radiation, light). And nothing in the Universe goes faster than light in a vacuum. To accelerate a single electron to lightspeed takes more energy than the Universe contains. The energy needed for further acceleration "tends toward infinity" when very close to lightspeed, as does mass. If hypernovas and Gamma Ray Bursts, some of the most energetic things in the Universe, are unable to accelerate a particle of matter to or above lightspeed, you can't, either. Relativity says you never will.
