Supermassive Black Hole Ejects Star from Galaxy

Sunday, November 17, 2019

Five million years ago, when humanity's ancestors were just learning to walk upright, a star was ejected from Sagittarius A*, the supermassive black hole at the center of the Milky Way Galaxy, at a staggering 3.7 million mph. This month, a group of researchers spotted the superfast star traveling relatively close to Earth.

The Gawdz version of a brain fart... and most likely a sign that Trumplethinskin is leaving office in disgrace.

Fascinating if proved true. Need to run this by my CalTech & MIT pals. Can physical objects travel so fast? (Roughly 1/2 of 1% of the speed of light.)

Sounds like it is proved true at least partially. It is traveling at the observed speed and the path it is on brings it back to Sagittarius A*. The binary star bit would seem to be the unproven piece and still it is fascinating without that.

Why wouldn't objects be able to travel that fast in space? I mean yes there are issues with that speed for a space ship but for a star - not so much.

The ONLY things in space that can affect other physical objects in such a way would be giant black holes, no?

Fascinating to know that we directly photographed a black hole just this year.

Things don't ejected from the galaxy easy. I mean we are one big family of stably rotating stars, all on predictable courses at the same speed for their orbit. The lunatic stars probably got tossed out long ago. Look, here is a documentary on it:

"Our" supermassive black hole. Say it with love rcade. Don't be a bigot when you change my titles.

#3 It's probably true. Cosmic rays travel more than 90% of the speed of light. 0.5% of that speed is probably possible if ejected from the gravity pull of black holes. But my brainier pals could probably explain it to me. Just think. Our nearest neighbor stars are more than 3 light years away. If human-made craft flew from Earth to any of those neighbors at the speed of this ejected star, it would be a 600 year journey. Guess Star Trek space travel is still a ridiculously hyped fantasy.

It was time for that star to leave the nest.

Fly little star, fly!

Good guess.

The distances in Space and Time between stars is so far greater than we could or even can imagine.

But the mind of man is capable of such fantastic leaps that you should never say never tho.

Asimov's Space Odyssey 2001 gets a bit closer to reality: earthsky.org
