Galaxies like to hang out together in groups, in our group at the heart is M87, a supergiant galaxy.
Messier 87 (also known as Virgo A or NGC 4486, and generally abbreviated to M87) is a supergiant elliptical galaxy in the constellation Virgo. One of the most massive galaxies in the local universe, it is notable for its large population of globular clusters—M87 contains about 12,000 compared to the 150-200 orbiting the Milky Way—and its jet of energetic plasma that originates at the core and extends outward at least 1,500 parsecs (4,900 light-years), travelling at relativistic speed. It is one of the brightest radio sources in the sky, and is a popular target for both amateur astronomy observations and professional astronomy study.
Once again when dealing with the wonders of our local supercluster we have annoying theoretical concepts hijacking the research.
“At the core of this galaxy is a supermassive black hole (SMBH) with an estimated (3.5 ± 0.8) × 109 times the mass of the Sun. This is one of the highest masses known for such an object.”
“So gravity pulls on light just as on rocks. We also know that we can put rocks in orbit, can we put light in orbit? Yes! but we need a very heavy object whose radius is very small, for example, we need something as heavy as the sun but squashed to a radius of less than about 3km. Given such an object, light moving towards it in the right direction will, if it comes close enough land in an orbit around it. If you place yourself in the path of light as it orbits the object, you’d be able to see your back.
But we can go farther and imagine an object so massive and compact that if we turn on a laser beam on its surface gravity’s pull will bend it back towards the surface. Think what this means: since no light can leave this object it will appear perfectly black, this is a black hole. An object which comes sufficiently close to a black hole will also disappear into it (since nothing moves faster than light if an object traps light it will also trap everything else).
The effect of a black holes, like all gravitational effects, decreases with distance. This means that there will be a “boundary” surrounding the black hole such that anything crossing it will be unable to leave the region near the black hole; this boundary is called the black-hole horizon see Fig. 7.10 Anything crossing the horizon is permanently trapped. Black holes are prefect roach motels: once you check in (by crossing the horizon), you never check out.”
But we find instead of stars being sucked into this supermassive black hole as theory would suggest..
Talk about getting the cosmic boot! One of the largest known galaxies in the universe, Messier 87 (M87), appears to have hurled an entire star cluster in our direction.

Ejection from black holes ?
So ejection comes from a black hole in the center that is supposedly pulling everything in.
That doesn’t make sense.. Welcome to black holes, a waste of our time.
I thought black holes sucked everything in.
