? @ 2.2 million mph how long would it take to reach 100 million years away?
Nice find

It's not measure in "years"...it's measured in "light years"...which is not the same as earth years. A light year is:
186,000 mi/sec x 60 sec/min x 60 min/hr x 24 hr/day x 365 days/yr
To learn more about these Fermi bubbles, the researchersanalyzed the parts of the sky including these regions using the Parkes Radio Telescope in Australia as part of the S-band Polarization All Sky Survey (S-PASS). They detected giant outflows of gamma-ray-emitting gas, two cone-shaped lobes that combined are about 50,000 light-years long.
"That is about half the size of the entire Milky Way," Carretti said. Seen from Earth, the outflows stretch about two-thirds across the sky from horizon to horizon.
[color=gold]
Each of these lobes is about 13,000 light-years wide, and made of gas traveling about 2.2 million mph (3.6 million kph).
"Beside the galactic disc, these are the largest structures ever discovered in our galaxy," Carretti said.
These outflows are about 100 million years old, and apparently spew mostly from supernovas within the compact 650-light-year-wide area surrounding the supermassive black hole at the core of the Milky Way. Supernovas are the most powerful exploding stars in the universe, bright enough to momentarily outshine their entire galaxies.
****This is why I asked how long would it take traveling 2.2 MILLION mph it didn't say ly so misunderstood. Thanks for clarification. Still at that speed a more accurate question is what region would these gamma rays be at as of now if you visualized the Milky Way from above divided in 3rds where are these rays at 100 million years ago emitted? CAN ANYBODY PRODUCE AN ACCURATE ANSWER?

If the question is how long will it take to reach 100 years away, the answer would be 100 years...
But that is beside the point.

OP a question about that very interesting pic you've posted. From a victim suffering with 0 knowledge of astronomy.
Why does there seem to be a perimeter where the stars just stop and then beyond that perimeter there is only a blackness ?

And the force that emanates from the center that is tied to and affects everything in the Galaxy... is...
gravity.
Can't you feel its pull? It made you respond to this thread.

. Some idea how to imagine what they are talking about. If you go to the link of the OP, here is the pictures caption; "This shows the geysers (in blue) shooting out of the Milky Way.
