What is at the centre of our galaxy ?

Question

please tell me, what is it there, and what are the forces that keeps it that way

ok if its blackhole then what is it that keeps it in place and what is on the otherside of a black hole ??

Answer 1

You already know that the "contents" of a black hole are hypothetical. You can, and should read the latest scientific journals, instead of BANGING YOUR HEAD around here for these answers.

But, remember, it's hypothetical. That means there is no fact, observation or direct measurement to support it -- only a whimsical logic.

Answer 2

The journal Nature had an article about this a little while back, if you can get to a university library to read it:

"A long time ago, in a galaxy not so far away

Vast stellar nurseries, clouds that dwarf the Solar System and lurking swarms of black holes. Jeff Kanipe probes the unfolding mysteries at the heart of the Milky Way."

There is a super massive black hole, but the region is also full of other stuff. If I remember the article correctly, the area very near the black hole is pretty quiet, and all the hot young stars etc. are a little bit out from there.

As far as what keeps it there, the answer is gravity - the same thing that keeps the center of the earth at the center of the planet.

There isn't any way to know what is 'on the other side' = the gravity 'bends' space so much that it is impossible to observe 'the other side'. The limit of where this change in spacetime occurs is known as the event horizon.

Answer 3

All celestial bodies seem to progress to something else.
This has to be the same for a galaxy.
The galactic center holds the key to it's fate,seeing what is at the center is not easy if at all possible.
A black hole is not the engine that drives the galactic center,so it must be something else,but what?
All the mass of a galaxy is approaching and accelerating towards the center.
As the star population gets denser,they will eventually merge.
In time we would end up with a massive ball of matter of incredible density.
A type of neutron star activity is annihilating matter and reducing the density of space.
As space rushes in to maintain it's integrity it pulls all matter of the galaxy in after it.
When the galaxy reaches a minimum size,it will,in a few seconds turn into pure energy and emit an intense gamma ray burst that will be visible for billions of light years and it's demise will delineate the maximum reach of the universe.

Answer 4

There is strong evidence to suggest there is a supermassive black hole at the Galactic Centre of the Milky Way.

Sagittarius A* (pronounced "A-star", standard abbreviation Sgr A*) is a bright and very compact source of radio emission at the centre of the Milky Way Galaxy, part of a larger astronomical feature at that location (Sagittarius A).

This might sound like it was dangerous but the Sun is approx 26,000 light years from the Galactic Centre and safe from its harmful radiation (or life would have not got started here). We (the Sun and its entourage) are located in the Orion spiral arm of the Milky Way.

On October 16, 2002, an international team led by Rainer Schödel of the Max Planck Institute for Extraterrestrial Physics reported the observation of the motion of the star S2 near to Sagittarius A* for a period of ten years, and obtained evidence that Sagittarius A* is a highly massive compact object.

From examining the Keplerian orbit of S2, they determined the mass of Sagittarius A* to be 2.6 ± 0.2 million solar masses, confined in a volume with a radius no more than 17 light-hours (120 AU). Later observations determined the mass of the object to be about 3.7 million solar masses within a volume with radius no larger than 6.25 light-hours (45 AU).

This is compatible with, and strong evidence in support of, the hypothesis that Sagittarius A* is a supermassive black hole.

It is thought that most galaxies have one and that they provide stability for the galaxy in the way the nearest stars rotate about it.

Answer 5

Everyones close, but its 2 black holes.

they keep themselves centered and will end up devouring each other.

we will all die. but its 100 million years in the future. gives us time to plan an escape if humans can make it that long.

its more like ..............the BH is so densely packed INSIDE there's not much on the "other" side sense there really isn't an "other side".

You could experience the inside of a black hole ONLY if you could travel deep into a quantum level OR exist within higher dimensions that aren't effected by gravity and attempt to enter.

some think black holes pack all the extra dimensions into each other causing small big bangs within the black hole, but its all theory.

if humans smashing protons can theoretically make big bangs, why couldn't an smashing mashing overwhelming force of gravity do the same thing?

parallel universes is interesting too

I believe in universes within universes within universes .....................

you get the idea.

There is no otherside of a black hole, it is the remaining gravity field of what was once a star

Answer 7

a Massive black hole

Answer 8

a supermassive black hole resides at the center of our galaxy. it weighs in at around several million solar masses, gravity keeps it that way.

Answer 9

.Most likely, the center of our galaxy is a massive black hole

Answer 10

a black hole
