So that, on this conspiracy site, your comment is not misconstrued as meaning that faster than light phenomena has been observed, here is a quick
If a particle jet 100,000 light years away emits light toward us it will take 100,000 years for that light to get to us. If that jet is traveling
directly at us at 99.999% the speed of light, it will take that jet roughly 100,001 years to get to us. So we will see the light from when it left
roughly one year before the jet gets to us. But this does not mean it took one year for the jet to get to us, and that it traveled at 100,000 times
the speed of light. No. It just means that the light arrives only a small portion of the time earlier than does the jet.
No violations of relativity. No faster-than-light travel. No time travel. No worm holes. Just standard stuff.
