Pizza Bar at the Centre of the Galaxy!

ok, one of the most amazing things i've seen in science recently is this picture of the centre of our milky way galaxy -

doesn't look much I know, but the stars in the centre are moving so fast that it means that over the course of a year they were able to make a movie of it, take a look here - http://www.mpe.mpg.de/ir/GC/download/motions.mpeg

You have to use your imagination a bit but they say these stars are in orbis around a black hole, a bit like a bigger version of the comets and planets orbiting around the sun.

What started me thinking about the pizza hut is that they say that there are other stars that are so close to the black hole that they orbit as fast as every few days, giving off huge explosions that can be seen even from earth.. what a great place to have a meal with arthur and zaphod, mines a gargleblaster Very Happy

thats so cool!!
so if im not mistakin thats a movie that took a full year to film??
if you think about the fact the earth is moving alot too maybe there are some ppl on that star (or planet) sittin thinkin why is that blue star over there moving all the time??? you never know i dont think any1 ever has been on one of those stars to proof there aint no life on it

its a really spectacular movie you got there thow
seriously dont hope the black hole excisting and if it does i hope it wont come near the earth that would be the biggest terror for us humans to happen would we survive a thing like that?? maybe yes maybe we would just replace to another place of the galaxy or maybe no maybe we would disappear or sumthin nobody knows maybe sum1 knows but he wont be able to tell us i guess althow i dont think any1 knows

No-one could survive a black hole. If you were to go in feet first, the force of gravity acting on your feet would be a lot greater than that acting on your head so you would be stretched - spaghettified, as it's known. There is absolutely no way you would reappear in another part of the universe.

wow. that tuely amazes me. Surprised

the fact that starts that far away moved enough that humans could RECORD IT IN A MOVIE is really cool. they would have to move millions of miles for us to see, just in about 5 years!

I think it is correct to say that the Super massive Black Holes referred to here are now thought to be a central component of all active galaxies. There was (what I found to be) a useful Horizon program on the matter not too long ago. Basically Astronomers have found SMBHs in every galaxy where they have looked. The question was then - what is the relationship. The first hint came with the discovery that the Sigma for a galaxy (a measure of the speed of rotation of the stars at the outside edge) is proportional to the mass of the SMBH. This led to the theory that galaxies form first when the cloud of gas collapses into an SMBH which sends a shock wave through the cloud triggering the formation of stars and ultimately solar systems.

Good to know that everything we do here on Earth and on Frihost will all be wiped clear when our planet and all of its inhabitants are sucked into the dark void that is the cause for the Milky Way galaxy. Thanks for that.
