Gaping Hole found in Universe

www.reuters.com

A giant hole in the Universe is devoid of galaxies, stars and even lacks dark matter, astronomers said on Thursday.

The team at the University of Minnesota said the void is nearly a billion light-years across and they have no idea why it is there.

i wonder if this is really a gaping hole, or if we just cant detect what is there , whatever it is its not 'normal space' as we know it.

a massive black hole? Space made of something we know nothing about?
a cataclysmic event of gigantic proportions.

or like the below poster says an unfinshed part of the simulation? have the walls finally been detected wobbling?

A "gaping hole" in space sounds rather odd. Nevertheless, it confirms how little we really know about our universe.

I found additional material about The hole in space which is a bit more technical than than the Reuters link.

All I can say is that I find this all quite fascinating.

Well if it is a black hole it would be emitting radiation. So I would think that would have been detected, so should not be a black hole.

forgive me my knowledge is limited on the subject but black holes i thought absouletly nothing escaped its pull not even light , so how can radiation particles escape?

the only reference i can find is on Hawking particles which are theoritical

In physics, Hawking radiation (also known as Bekenstein-Hawking radiation) is a thermal radiation thought to be emitted by black holes due to "quantum effects". It is named after the British physicist Stephen Hawking who provided the theoretical argument for its existence in 1974, and sometimes also after the Israeli physicist Jacob Bekenstein who predicted that black holes should have thermal properties. Because Hawking radiation allows black holes to lose mass, black holes which lose more matter than they gain through other means are expected to evaporate, shrink, and ultimately vanish. Smaller 'micro' black holes are currently predicted by theory to be larger net emitters of radiation than larger black holes, and to shrink and evaporate faster.

here is the link again benevolant tyrant i had this trouble you have to take the full stop/ period off the end of the link

And for folks that cant be bothered to click heres the picture in low res , medium and high are available at the link

Illustration of the effect of intervening matter in the cosmos on the cosmic microwave background (CMB). On the right, the CMB is released shortly after the Big Bang, with tiny ripples in temperature due to fluctuations in the early Universe. As this radiation traverses the Universe, filled with a web of galaxies, clusters, superclusters and voids, it experiences slight perturbations. In the direction of the giant newly-discovered void, the WMAP satellite (top left) sees a cold spot, while the VLA (bottom left) sees fewer radio galaxies.

lol same here. I THINK that its just the Black Hole, uh, "burping"? Thats how i think it is anyways, kinda like Quasars, always pulsating waves/particles.

~~~~~~~~~~~~~~~~~~~~~~~~

If it were to grow at an exponential rate, like a universe eating black hole essentially restarting everything......hmmmm. I think that would put EVERYTHING IN HUMAN HISTORY FLIPPED UPSIDE DOWN, SLAPPED FOR FUN, FLUSHED DOWN A TOILET AND COMPLETLY IMPLODED ITSELF.

lol idk what i am talking about now. Just thinking about it gives me the brain willies. lol . A million Earths before us? A million differnt time streams?? WOWO



THANKS FOR THE PIC THERE QUANTUM SQUIRREL!!! NOICE. It puts it in a better perspective

Lol its the "Nothing" from the never ending story! We just have to believe in our imagination and it will go away. make a wish! even two!

Great find as allways OP!

Lmao are you saying is time to break out the flying dogs?

I am sorry I did not get back to you sooner. I missed the post when I came back to review the topic.
I first heard that black holes emit radiation back in the mid 1980s. It was the theatrical version of A Brief History Of Time. The scientist who found it was working with Hawking and won a Nobel prize for his work, as I recall to the best of my knowledge. Hear is the link to a more recent version of A brief history of time. I do not know if the little fact that black holes are not completely black will be in there. But I will post more information if I come across it.

you bring up good points and i must say i agree with you

this is crazy... a billion light years across!?

hopefully they keep an eye on it so they can determine if it is expanding or not

Additional information to back up my previous post in this thread.

Image left: Many black holes, notorious for pulling matter in, somehow generate particle jets shooting matter away at nearly light speed. Data from the Swift satellite may have solved the mystery of the nature of these jets. Data suggest they are made of electrons and protons."Click image to enlarge.
