Since the speed of light is relative to the initial starting velocity, if a lightsource was traveling at C velocity north and shined the light South, what would a stationary observer see?

A straight line of light or a flashing ball, depending on the position of the stationary observer.

Really? Did you look that up? I was never quite sure. 'Cause wouldn't that mean the light was stationary relative to the stationary observer? Would they see no light? It's confused me for years...

Can you blow bubbles with your nose?

Nope. Try to and failed lol

Not even underwater?
