#1 One of the most powerful shock waves recorded by astronomers in the entire history of observations has reached Earth.

Due to P.Trump's election.

290 million light years from Earth, is about 1,703,630,854,080,000 miles in distance. (1.703 Quadrillion miles)

Since light travels much faster than a Shock wave. Have we actually exp. what Astronomers saw yet?

Also, wouldn't this 290+/- year old Shock Wave have spread out 90 to 180 degree cone and dissipated?

WiKi (Researchgate.net) "Over longer distances, a shock wave can change from a nonlinear wave into a linear wave, degenerating into a conventional sound wave as it heats the air and loses energy. The sound wave is heard as the familiar "thud" or "thump" of a sonic boom, commonly created by the supersonic flight of aircraft."

#5 I think that sound waves need a medium to propagate. Hence no sound in a vacuum. What is the medium for this? They proved the non-existence of "ether" long ago, right?

Ain't the science settled? (see also #3)
