Hubble Reveals Ghostly Ring of Dark Matter

Hubble Reveals Ghostly Ring of Dark Matter

www.livescience.com

Astronomers have discovered an enormous, ghostly ring of dark matter 5 billion light-years away--the most blatant evidence to date for the existence of a mysterious substance hidden throughout the universe.

It's a good thing, it means that dark matter does indeed exist and thusly fills in quite a few holes in our understanding of the Universe.

"By studying this collision, we are seeing how dark matter responds to gravity," said Holland Ford, another Johns Hopkins astronomer on the team. "Nature is doing an experiment for us that we can't do in a lab, and it agrees with our theoretical models."

We've pretty much assumed it existed but this particular ring, pretty much proves its existence.

can someone tell me (since im to lazy to do research at 1am..lol..how far is 5 billion light years in miles? I ask because how in the *$#@ can ANYTHING see that far? I'm sorry but something tells me hubble isn't what they are using to see that far into space. I mean tell me its 5000 miles away..ok I can get on that bandwagon. But 5 BILLION light years...I think something is either a little fake, we are using FAR more technology then NASA will admit, or I just can't phathom being able to see that far through a manmade telescopeish type thing..lol.

If we see something that's 5 Billion Light Years away, that means
we're seeing this dark matter as it existed 5 Billion Years Ago.

It might be gone, or condensed into stars by now. Right? How
does something that existed 5 billion years ago help scientists
formulate theories for the current state of the cosmos and it's
future? -CWM (Chicago)

Ahhhh... It appears my arch nemesis AnAbsolutecreation, already started a thread on this topic HERE

It appears as though he has won this time......but I'll be back.

Please post on that thread cause this one is

CLOSED!

They already knew about that, they are working on anti-matter bombs...

Air Force pursuing antimatter weapons
It was a leak... so maybe it's new for the civil side... but for the military side, it's old news. I hope they don't test it on earth... many scientists think it could even blow up the entire solar system... I hope they don't test it at all.

Technically yours was first Kleverone.

Five billion lightyears is 29,392,499,070,930,000,000,000 miles, in other words it's
roughly 29 sextillion miles away.

I ask because how in the *$#@ can ANYTHING see that far?

Well it's a very, very large structure, roughly the size of a galaxy itself, add to that that the Hubble,
as all space telescopes are capable of seeing things very far away because of their
being in space and staring at an area for quite a bit of time, collecting a lot of light.

I'm sorry but something tells me Hubble isn't what they are using to see that far into space.

The Hubble telescope is only designed to see far into space, it is not capable of
seeing close objects.

If you really want to understand it, I suggest reading up on telescopes, optics,
astronomy and astrophysics.

I mean tell me its 5000 miles away..ok I can get on that bandwagon.

The Moon is 238,857 miles away, the Sun is 93million miles away.

They are very close to us on an astronomical scale.

But 5 BILLION light years...I think something is either a little fake, we are using FAR more technology then NASA will admit, or I just can't phathom being able to see that far through a manmade telescopeish type thing..lol.

Nothing is fake, and we don't have super advanced optics software, as I said, you should
read-up on astronomy and telescope optics if you really want to understand it more.

You are indeed correct, well unless there is some weird space-time altering phenomenon
between there and here that is speeding or slowing the light transmission, but the likelihood of
that is astronomically small.

It most likely is still there and in roughly the same form, stars and planets are made up of
normal matter, it is not known if dark matter can form into dark matter stars or planets,
though even if it did, we'd never see them.

This basically says that we were right, dark matter was theorized to explain why the
Universe was not just still expanding, but at an increasing rate.

This finding basically tells us that, yes, dark matter does indeed exist.

Dark matter and anti-matter are two completely different things, dark matter is a
substance that we can not see or interact with that makes up a great deal of the Universe,
anti-matter is part of the 10% of normal matter, that is what makes up the planets and stars
and you and me, it is simply matter with the opposite polarization.

While anti-matter has been looked at as a weapon, it is, for the mean time not something
that anyone is going to actually build a bomb out of, not only is it incredibly difficult
to store, and takes a long time and a lot of money to make, it would take centuries to
make enough for a single bomb using the technology of today and the foreseeable future.

Apart from that anti-matter is really not worth pursuing, as it is incredibly destructive,
producing a 100% matter-energy conversion, and while we all live on one planet,
that's just not something anyone is going to develop.

It was a leak... so maybe it's new for the civil side... but for the military side, it's old news. I hope they don't test it on earth... many scientists think it could even blow up the entire solar system... I hope they don't test it at all.

If/when anti-matter weapons are ever tested, it will most likely be on an asteroid,
or at the closest the Moon.

While with enough anti-matter you could theoretically create an explosion large enough
and powerful enough to destroy the solar system, the amount required would be immense,
requiring enough anti-matter to make an entire planet, if not super-giant.

Ah but should we really shed light on the young apprentice? He sees what he wants, always has.

Bravo, my boy. Perhaps I was just reading your thoughts... again.

Amazing picture:

I wonder if our Sun is that "close" to other stars? Or are those galaxies like our Milky Way? Would really give us some perspective to the galaxy / universe.

go type in google video or youtube.com search bar

reverse engineered ufo

i found a video that may have been fake, but certainly big money and included some scientific realities pointing out things light anti-matter time folding-or warp drive, transporters, even bathrooms in the ufo. i want to believe mulder..i do. Anyway bmw is going to be releasing the disc vehicle
around the year 3057, though training will take about 3 years to fully understand the physics of time/dimension shifting and creating wormholes in a safe area and not arriving inside a planet or sun. And dark matter rocks btw. yes im high.

This is really nerve wrecking.

The scientific religion that is forming around us.

It's vexatious to see peoples claiming percentages of dark matter and "anti-matter" in the universe etc.

Its purely pseudointellectualism, and I don't mean lacking scholarly back ground, I mean lacking factual data and cerebral density on the means of any basis to make such absurd judgements and announcements.

NO ONE has ever "measured" the universe. NO ONE has ever nor will ever optically see the entire "universe", because it is eternal in both space and time. Thus no one can ever derive percentages from a thing that they have not measured nor comprehend, that is merely mathematical inexactitude, personal razzmatazz, and scientific confusion trying to be passed off as phrenic dominance. Just like Jesus is in Heaven having a party in the clouds, percentages of the universe as a whole can never be measured.

You see, it's really quite simple. When you are yet to "measure" a thing (by the way, a thing that can not be measured["uni-verse]) you can not begin deriving percentages that are based on a 100% scale of that thing that is neither 100% measurable (whole: beginning and end) nor currently 100% measured (and never will be).

Excuse me while I orally induce my heart medicine and re-read my "how to understand Human stupidity" brochure.

All jokes aside... develop already

Astronomy Geek to the Rescue!
1 Light Year is the distance that light travels in one year. Grab a good calculator, and oil that '0' key, we'll need it.

Speed of light = (approximately) 186,282 miles / sec.
60 seconds in 1 minute gives 11,176,920 miles / minute
60 minutes in 1 hour gives 670,615,200 miles / hour
24 hours in 1 day (more or less, again) gives 16,094,764,800 miles / day
365 days in 1 year gives 5,874,589,152,000 miles / year.
5 billion light years would thus be 29,372,945,760,000,000,000,000 miles.

As for how we see that far, you have to understand that an astronomical telescope isn't about 'magnification'. It's not magnifying anything to make it visible, like a set of binoculars or a hand lens does. They are designed to gather as much light as possible. They do that through a combination of objective sizes (either lenses, for a refracting telescope, or mirrors for reflectors like the Hubble, Hale, or Keck), and VERY long exposure time. When you take a photo with a camera, your shutter speed ranges from 1 second of exposure to 1/8,000th second of exposure. An astronomical scope uses 'shutter speeds' measured in minutes (or even hours, when examining faint objects)...there's a fairly complex high-precision drive on the scope mounting to move it counter to the Earth's rotation to allow exposures that long.

The more light you can gather, the more you can see. It's not 'new tech' or high tech at all. Gallileo and others were making telescopes in the early 1600's. The Hale telescope at Mount Palomar is still one of the world's largest (200" main mirror), and construction on it ran from 1934-1948.

If you doubt that we can see that far with technology, let me put a few other things in perspective. You can look at something 98,000,000 miles away, and damage your eyes (the sun, on a clear day)...and after dark, with good conditions, you can see the Andromeda galaxy, 2.5 million light years away. On a really exceptional night, Messier-33 / Triangulum is visible, at 2.92 million light years, all with the naked eye. (If you want to translate those into miles, it's your turn to type all the zeros! ).

5,000 miles is rounding error by astronomical standards. That's about 1/50th of the way to the Moon, which is (obviously) naked-eye visible. The moral of all those zeroes? The universe (whether you think it eveolved, or was created) is a *VERY* big place, and Earth is *VERY* small.

Brother and Lori, thanks for the input. It is definitly amazing to see and read about. And out of curiousity, have we ever been able to see through any of our technology..what science calls the edge of the universe? As bright and detailed as the picture is of this dark matter, there has to be pictures of space even further away right?

I think its way larger then that, you are seeing galaxy clusters in this picture,
1000s of galaxies, the size of this is mind boggling

uhhmmmm...

STOP!


copuld you stop please?



excuse me...

one moment.



but that is not proof of dark matter at all....

it looks like there was a giant explosion in the centre and this shockwave pushed the glowing gas outwards in a ring.....


THE APPRRENT CONTRAST BETWEEN THE GLOWING MATTER AND THE NON-GLOWING MATTER IS GIVING AN IMPRESSION OF A RING OF DARK MATTER...

BUT IT'S JUST A MASSIVE SUPERNOVA....

looks like a powerful super supernove...LIKE THE ONE REPORTED HEAVILY 2 WEEKS AGO...

if you look closely you can see other objects THRU the dark matter...


also the dark patches give an impression of an explosion....
some parts of the glowing ring have shockwave artifacts on the inner edge of the circle...

like an uneven explosion..



the ring is simply the REMNANT OF AN POWERFUL EXPLOSION AWILE AGO...

in their search for the non-existant dark matter astronomers are clutching at anything to backup their ludicrous theories....


llook closely....

Our sun has a relatively close neighbor....the Centauri triple-star system, at about 4.6 light years seperation. As for the bodies in that photo, it's hard to tell, since they are seperated in three dimensions, but represented in two. There are places in most galaxies (usually toward the center) where 4.6 light years would be well under the average distance. Not trying to be evasive, but there really isn't enough data in that photo to give you a better answer.

For your second question (or the second part of your question), the objects that have a lenticular shape are probably galaxies, and the objects with the cross-pattern 'rays' are probably stars. Incidentally, the rays are an artifact of the telescope structure...usually interference from the mirror / equipment supports. Actuall stellar images are just dots, which confuses a lot of people, who keep looking for something 'star shaped'.

You're right though, about that shot giving a good perspective on just how flaming huge the universe is...think about it...somewhere, near one of those points of light, Trelfnebian internet junkies are posting to a conspiracy board and debating the possibility that life might exist on a Trelfneb-like planet in the Sagittarius arm of the galaxy.
