> I do not see anything going FTL anywhere right now. Other than distant galaxies from each other.

  Kind of a sad reflection of society that this comment is grayed out. In that the person downvoting it was so certain it was wrong, they didn't even stop to consider they might be the one who is wrong - and they are. [1] Galaxies are already moving away from one another at speeds greater than the speed of light. So the speed of light already has at least one asterisk there. In that nothing can be perceived as moving through space at speeds faster than light, but the expansion of the universe can happily send objects drifting apart at speeds well above the speed of light, and accelerating.

    It's greyed out because it's FTL by technicality. If FTL had an appropriate name, it would be clear why it doesn't count. Take a strong laser pointer and point it at one side of the moon. Then flick your wrist to point it at the other side. The laser just "broke the speed of light" but it didn't transfer any information so it's all good.
