Both radio observations with the VLBA and optical observations with the Hubble Space Telescope have measured the motions of concentrations of material in M87's jets, and have shown the material to be moving at apparent speeds greater than that of light. This "superluminal" motion is a geometric illusion created by material moving nearly, but under, the speed of light, but in a direction somewhat toward the Earth. |

I've walked these streets
A virtual stage
It seemed to me
Make up on their faces
Actors took their
Places next to me Natalie Merchant, Carnival
I've walked these streets
In the mad house asylum
They can be
Where a wild eyed misfit prophet
On a traffic island stopped
And he raved of saving me Natalie Merchant, Carnival

Just about 14 Billions years ago, the universe flickered into existence in an event know as the Big Bang.
