But if it was travelling fast enough, its light would be Doppler shifted to beyond the visible spectrum .. but then, and lower frequency EMR from it could be shifted into the visible spectrum.

We're told by our peers that the outer parts of our universe is likely expanding/receding at c, as sort of leaving us in its photon dust that we'll never detect. Stop avoiding the truth-seeking context or intent of my topic. LHC proves that matter can be artificially directed towards other matter at a closing velocity of <2c. ~ BG

I'll assume just a tad under light speed... There would be a glowing path of destruction in its wake, and even more energetic particles leading it. There are very few directions that would not show its passage towards us. Note that the blue shift would make even a brown dwarf into something quite bright, and deadly. David A. Smith
