A Monster Misses a Meal

There is a monster at the heart of our Milky Way Galaxy.  It's a super-massive black hole that has already eaten enough material to make 4 million stars like our Sun!  And, like all black holes, it is still hungry.  

For material to be "eaten" by a black hole, it must come quite close to the black hole "mouth" which astronomers call its event horizon.  Because black holes are the most compressed (squozen) objects in the universe, even overfed monster black holes have relatively small event horizons. Astronomers estimate that the one at the center of our Galaxy is 80 to 100 million miles across.  That's roughly the distance between the Earth and the Sun and is a tiny space in which to put 4 million(!) Suns.

So material near our black holes must come close to that tiny region to serve as food for the monster.  Things further away, like stars, can orbit around the black hole and not get swallowed.  (It is from the movement of such close, but not doomed, stars that we can estimate the gravity of the black hole.)

For the last few years, astronomers who monitor the center of our Galaxy have been predicting that a snack is on its way to the black hole.  A dusty cloud of material which they have nicknamed G2 was going to have a close encounter of the worst kind with the black hole in May 2014.  It was going to be torn apart by the enormous gravity of the monster and some of its material was then going to provide a meal for the black hole.  

When gas clouds (or other food) fall into a black hole, they are whirled around with unbelievable speed just before they fall in, and tend to glow briefly with x-rays and other forms of radiation before they disappear in the event horizon. However, no such flare-up of radiation was seen, even when the world's largest telescopes (like the Keck in Hawaii and the European Very Large Telescope in Chile). 

It appears G2 was not torn apart and consumed, because it wasn't a loose cloud of raw material, but a star with some of its birth material still around it.   The star managed to hold on to its "stuff" and make it away from the black hole, depriving it of a meal at this time.  Sorry, monster.   Better luck next time.

(In the picture, you see G2 in different colors going around the black hole (which is invisible, but whose position is marked by the plus sign.)  The blobs are shown at different times, and are red when G2 was moving away from us, and blue now that it was flung around the black hole and is coming toward us.)


  1. Thank you for the great article and heads up! I'll be sure to avoid this black hole if I'm heading to that part of the galaxy!

  2. Want to know how to get over a broken heart? A break up can feel like the end of the world, but if you really do want to move on, here’s a complete guide on how to deal with a broken heart.My name is Mimi Bieber, i live in Tx,USA. since 6 months I have witness what is called heart broke. my boyfriend that promised me marriage failed me and impregnate me and leave,he dump me,he stop calling" he stop picking my calls,and he no longer respond to me. I have be looking for solution,I fall into the hands of fake spell caster,they rough me off and took my money without help.I have cried,I have weep"and tears runs out of eyes. The silentness in my heart brought me to the deepest path of failure that I lost my job. Crying all day,because of my life was lonely. So thanks to Dr Brave that came into my life and brought me the greatest joy that was lost. I saw his mail while browsing and I contact and tell him what I am passing through with no doubt because what saw about him,was enough to believe. And I was given words of solution on what to do. I can't really help thinking about it I have tried to see what I can do, I manage to provide him some materials and he help me with the rest,after casting the spell, 12hrs later he came with rose on his hand and I was even about going out,i saw him in front of my door when he sees me he knee and said he is dying I should forgive him and accept him back he was crying,I can't wait to let him finish I quickly crab him and kiss him, just then" he said he is restless without me, just as the prophet has said he will be. He brought out a ring and put it on my hand. Our wedding day was scheduled,1week after we got married. today makes it 2weeks and we are living happily I don't know how to praise him enough, he has done me a thing I can never forget. And I can't really share to myself alone, I want y'all to help me praise him because if it is wasn't for him I already plan of committing suicide. But right now I am now so happy more than I was before. And you out there crying for help you've already got one,Dr Brave is the man that you need in all rampart. contact his address if you need his service, also contact him on his web site: you Dr Brave, i will always be testifying about your good work.
