back to article Hubble snaps dark matter warping spacetime

The Hubble Space Telescope has taken a 19-hour snapshot of galaxies whose images have been warped by the presence of the baffling interstellar substance known as "dark matter", residing in an intervening galactic cluster. The image, released Thursday, shows the cluster – known prosaically as MACS J1206.2-0847, or simply MACS …

"which would make it 4.5 billion light years plus 600 kilometers away from us earthlings"

I heartily commend your accuracy.

The plus 600 kilometers is the distance between hubble and earth, infact its 569 kilometers :)

Fantastic image. The people demand more.

> in the current US political climate, its multi-billion-dollar price tag makes it a prime target...

Sod that!

I hear Eric "Fast And Furious" Holder is currently busy stoking the propaganda machine for action against Iran with bad plot devices. Just in time to divert the restless people at home. Don't tell me there isn't space for a few more "billions and billions" (excuses to Carl Sagan) in the Fed's RDBMS.

Paper money dark matter - nobody sees it, but everyone feels its beguiling pull. And suddenly it's too late.

Indeed. We need to investigate the source of this mysterious and malign power and shut it down if we can. Then we can enjoy our star-gazing in peace and quiet.

The ITelescope

Maybe the can get Apple to sponsor the new telescope. Perhaps create an app which streams video content from the telescope to billions and billions (I think Carl Sagan and Steve Jobs were related) of IPhone users.

I'm sure with Jobs' famous generosity for charitable causes Apple already has a fund waiting to be spent on such a worthwhile endeavour.

NO, Apple won't sponsor anything that photographs galaxies, unless it's to make them the same size as an iFad.

Dark matter

does not, as the article claims, make up >90% of the universe - that's the figure for dark matter and dark 'energy' combined. Dark matter is estimated to make up 23% of the universe - still 5 times as much as ordinary baryonic matter.

I think that dark matter

Is actually other universes impinging on our space/time.

A simple analogy would be a person living in 2-D land having their 'floor' pushed up from beneath by an external person in 3-D land.

The article didn't say 90% of the universe. It said 90% of the matter.

(I had the same initial reaction but re-read it).

That seems unlikely

unless other universes particularly enjoy pushing at galaxies.

Although I suppose it's possible - but not very plausible - that dark matter wrinkles created the gravitational wells in which galaxies formed.

At that distance they've probably already impinged and it's too late. We're all doomed to invasion from the hordes of Zen and need to call in the Industrial Military Complex to study this in greater detail, starting with funding the telescope.

matter matters

@Chris Miller

The statement was not that it made up 90% of the universe, but 90% of the matter in the universe. That statement is correct.

The total universe, or rather the energy in the universe is made up to ~ 75% of dark energy. That leaves ~25% for matter. Out of those ~25%, ~23% are dark matter. This means that ~92% of all matter dark matter. Exactly what was said in the article.

matter *does* matter

If you want to speak of the total mass/energy of the universe, normal matter makes up slightly less than 5%. If you want to exclude dark energy, then dark matter is about 5/6 of the universe. So in either case, the article is incorrect, and I stand by my comment.

This is my thought also.

In string theory, gravity is not confined to a single universe but is allowed to range through the 'bulk' between universes. The past and the future are special cases of multiple universes, and there is a range of universes encompassing every possibility that has come out of quantum results in the past. As time goes on, you would expect the gravitational effect of 'dark matter' (gravity from other universes) to increase as the number of resulting universes increases. This should be falsifiable.

Talking about the last sentence, of course.

By the way, can someone remind me how much the amount spent on the USA presidential race in 2008 was?

Yes. We're screwed.

Spot the duplicates

It's just a pity that an image wasn't produced that actually identified some of the "47 multiple images of 12 newly identified distant galaxies". I can see objects that appear to be the same, but I'm no expert and one galaxy can look pretty much the same as another.

A few helpful annotations would have made this picture even more awesome.

"one galaxy can look pretty much the same as another"

Yeah. That's why I gave up on intergalactic tourism. You travel billions of light-years just to and it's still Starbucks and McDonalds.

Gas Cloud Lensing?

Professor Bruce Draine, at Princeton, pointed out some while ago that as well as lensing by distant galaxies a similar process could occur with relatively nearby gas clouds.

ftp://ftp.astro.princeton.edu/draine/papers/pdf/ApJL_509_L41.pdf

It would be interesting to know how many examples of lensing have been examined using spectroscopy to check for the absorption lines that would signify gas cloud rather than galactic.lensing.

Dark Matter

It exists, we just havent got our heads around how to detect it...yet

It'll be everywhere once we do and then we will have our cheap method of transport into space and back.
