what's there in the center of milkyway?is it same for all galaxies?

Answer 1

There is a 3 million solar mass black hole in the center of the Milky Way. The evidence for this is quite clear nowdays.

A current working hypothesis in astronomy research is that all galaxies of all types have central black holes, and that the mass of the black hole in each case is a fixed fraction of the total mass of the galaxy (most of which is dark matter). So far the evidence for this hypothesis looks pretty good. "Small" central black holes have been "detected" in some small galaxies.

There are numerous theoretical explanations for this (possibly correct) hypothesis, none of which are as yet widely accepted.

Answer 2

The Milky Way is part of a group of galaxies held together by gravity called the Local Group.
The Milky Way is a spiral galaxy, which is thought to have a giant black hole at it's center.
Other type galaxies are Elliptical, Irregular & the Barred spiral. Since these are of different types and shapes it is unlikly all are the same.

Answer 3

properly sorry however the main reason is what the black hollow does suitable to what that is enable me clarify with my concepts in case you flush a rest room water is escaping by using a hollow gravity pushes the water and under the water gravity facilitates pull by using the hollow ' the water no remember the place you're interior the earth will spin around clockwise in line with risk yet iit will consistently spin cuz each galaxy has a blackhole based on the age of the galaxy relies upon on how that is going to look ours is rather previous those with like 2 palms are youthful case in point in case you place cinnamon in eggnog in case you ever have and stir it with a spoon then it might first turn to love palms and appear like that form of galaxy then aftter time it might appear like our galaxy ( ; and final if the galaxy became the form of a sphere the black hollow may be the form of a ball LOL yet its not the form of a ball its the form of a flat basketball or a flat sphere what the black hollow suks in does not pull from all guidelines it has to head by using its donut like center and out the different area the stars are spiralling around it like a cinnamon bun and additionally in case you're taking 1 / 4 and a string and spin it around it fairly is yet another element a black hollow does will the string and quarter flow in a ball like atom or a Frisbee like direction long answer yet YOU had to be attentive to

Answer 4

The centre of most spiral galaxies like ours is a supermassive black hole. Scientists have imaged the material being sucked into the black hole:

Not all galaxies seem to have black holes at the centre. Small, irregular ones don't seem to. ("Small" being a relative term; we ARE talking about galaxies here.)

Answer 5

Current theory speculates that a massive black hole sits at the center of any spiral galaxy. And by massive black hole I am NOT referring to Oprah Winfrey!

Answer 6

Most agree it to be a giant blackhole. So someday, trillions of years from now, we may all end up there, if the sun hasn't consumed us yet :) lol. Hope this helps!
