astronomy disscussion

I'm taking astronomy right now and I'm being exposed to a
lot of new info(for me anyway). at the center of our
galaxie there is said to be a black hole 2.6 million times
more massive the sun. I also wasn't aware that the solar
system revolved around the galactic center. does anyone
know if there are theories relating to possible galactic
orbits around something even more massive?

I dont understand, how can we find a center to something of
unknown size?

job,

thats a good point. I think it has something to do with
with the extraordinary amount of mass in a given area. I'm
sorry I can't say more(this isn't my best subject). anyway
they've labeled the particular point sgr A. that seems to
be where the most activity is coming from.

yes, the solar system revolves around the center of the
galaxy. there are galaxy clusters and our galaxy might be
part of one of these clusters, revolving around the center.
then there are superclusters and who knows how far it goes.
i'd like to know much more about the cosmos.

NO matter what direction you head in you will eventually end
up in space, therefore eventually we'll understand it
better.

JOB, our galaxy that he is refering to and the universe are
different things, so they can estimate the size of our
galaxy inside of the universe... is that what you mean??

does anybody notice how many people are incredibly ignorant
about the basics of astronomy? some people watch Star Trek
and star wars, and they don't even know what a star is and
what planet is, and what is meant by an orbit. i find that
strange, but then a lot of people dont have a clue where
afghanistan is on a map, so i guess its the same thing....

So do you think the sun is running out of fuel too soon???

apparantly there may be millions of tiny black holes
blinking in and out of existence all over the place - even
where we are now, so the theory states

How scientists discover this shit? Or do they just pull
crazy theories out of their ass? I'll never understand the
insane mathematical formulas they use.

I just want God or whoever or whatever to come down and
explain everything to me, explain everything about the
universe, because scientists just fucking confuse me.

Yeah, i heard that, its a possibility that one could appear
and suck my face in. Infitesimal chance though, but still
could happen.

Most people seem to get thier knowledge from
discovery/horizon type things, which is cool, but i find
reading a book is better.

i read about that theory in AtTheEdgeOfTime by John Gribbin

i heard the sun has enough energy to last another 5 billion
years.

i thought it was more like a few million

no its supposed to be a few more billion
its supposed to be about half way through its life cycle
right now

re. our galaxy orbiting around something.. well i dont think
it has a clearly defined orbit around some particular object
or anything like that..
..the galaxies in the universe are moving away from each
other, expanding
we can tell this from the red shift
but still not everyone is moving away from everyone.. some
are moving more towards each other and occasionally they
collide, which makes for some really cool looking images,
which u can see on:
http://hubble.stsci.edu/

so i bet our galaxy is moving around, and is affected by the
gravity of other galaxies, but not exactly orbiting
something

btw: ubik, ya i know what u mean
so many people dont even know what a galaxy is and how its
different from a solar system

if it takes millions and millions of years for anything to
develop in the universe, why should we, who live for a
measly 70 years average be bothered about all that shit?
i mean its fascinating and all that, but there aint fuckall
anyone can do about its developement

anyway, did yu know that an asteroid called Toutatis passed
near us, 48000 km. 48000 km is nothing in the universe when
yu travel at 1500 kmh...
48000 km is the distance to yer WC in the universe.
