I love Sixty Symbols. I also like Meghan Gray's answer to favorite Astronomical feature... then again I also dig her so that may slant me some. The lens effect is excessively cool. But I agree with the last guy, the Hubble Deep Field and Ultra Deep Field images are some of the most amazing images in the world and tend to be my favorite.

So would you say that you'd shove your white dwarf into her black hole?

I agree this video does a terrible job answering the original question. It simply doesn't.

I can extrapolate from the video and get some answers.
1) The (observable) universe is not spatially or temporally infinite.
2) Therefore all directions do not see a star.

A look at the Hubble deep field images can confirm this -- there's plenty of black space between the first visible galaxies at the edge of the observable universe.

Additionally there is a lot of dust, as others have mentioned.

what do they actually even do up there?
i now i'm being ignorant and that they probably do a lot of great stuff but we never specifically hear about any of it
there's never been a news story like "bananas made of jam invented on ISS! astronaut Jamforbrains gets nobel for being awesome!"


Rofl..

He's probably involved in various zero gravity experiments up there, acting as proxy on behalf of people on earth who come up with new questions as to what happens if you do this in zero gravity. I don't know the specific purpose of the ISS unfortunately, but i suspect your question is a bit like asking "Why are you looking through this telescope at the moon?"

And the answer is, who the hell knows what you'll find? Why did we sail around the world and discover new countries, new species of animal.. why do we still search for new species? Why do we test those species of plant and animal to see what they do, what they're made of, what properties they have? Why step outside of our front door?

Because if we didn't, we'd never have invented the wheel or mastered fire.

Imagine how much shit we've found in our own oceans that we didn't know about a few hundred years ago. Imagine what we've done with that new knowledge.

Can you possibly begin to imagine the sort of shit we might find out there in space, which is infinitely bigger than our ocean?

Imagine if you'd asked marie curie why she was messing around with a luminous material? "Did you make a banana made of this new material? Stop wasting your time!" And we've just lost the x-ray machine.

Cmon, man.. that sort of question depresses me.. of all the amazing things we've found out through stargazing, through expeditions into space (the hubble deep field picture, to me, is worth all the money on earth) the one thing that would validate such a trip, to you, is a fucking jam banana?

^ Because galaxies are the only structures large enough to show up at those distances. Stars from our own galaxy that lie in the foreground of the image have a kind of cross shaped lens flare, as in this deep field image (bottom left quadrant):

this video may have better music, but this video on the same picture is more brainy
http://www.videosift.com/video/How-the-Hubble-Deep-Field-Was-Taken

Amazingly, NASA took the famous deep field photo and passed it through a signal analyzer consisting of 200,000 quad-core CPU's in a Beowulf cluster running a stripped down version of Redhat's RHEL. For roughly 10^29 iterations, these processors ran an optimized fast Fourier transform on the collected data until a pure signal was collected. That signal, a complex series of interlocking sign waves, was then passed through the cluster again, the researchers were totally shocked by the result. A single, simple message, broadcast by the universe its self, to the human race:

"Sarah Palin's a cunt."

Science is truly, truly amazing.

Hubble Ultra Deep Field 3-D Fly-Thru
A flight through the Hubble Ultra Deep Field, the most distant visible-light view of the universe. The redshifts of 5,333 galaxies were converted to distances to assemble a 3-D model of the data. This scientific visualization flies through the data to showcase its true 3-D nature.

Fucking amazing. That's yours?

Yep stars live a long time. Plus the galaxies are generally around also. The universe started out with a big bang, matter starts coallescing and forming structures. Dust clouds form into stars, stars get captured into clusters and galaxies, galaxies get trapped in galaxy groups and interconnected sheets of galaxies. The universe is expanding like a loaf of bread where all points are always getting farther away from all other points, but gravity can keep some of these structures together. The black holes at the centers of these galaxies are holding on to their stars.

I like to take 50+ exposures of galaxies I am working on, but nice results can be had with a lot less exposures, this is only 20 exposures: http://www.scopenews.com/m51postcard.jpg

And all those galaxies in that image have collapsed/blow up and are no longer there and haven't been for millions of years. That blows me away.

Well, the individual stars within them that actually gave off the light would be gone, but the galaxies themselves would still be there, perhaps giving off light with new stars.


The majority of those stars would still be present. There's a large variance in the lifespan of stars, inversely proportional to the mass of the star. The median mass of stars in our neighborhood is 0.5 solar masses. Stars such as our Sun will burn for about 10 billion years. Stars half the size of our Sun could have started burning when the universe formed and still be going.

Your video, How the Hubble Deep Field Was Taken, has made it into the Top 15 New Videos listing. Congratulations on your achievement. For your contribution you have been awarded 1 Power Point.

Humans are creatures of imagination and emotion, and listening to Dawkins talk about DNA, while interesting, will never replace religious storytelling.

Maybe not Dawkins / DNA specifically, but I find science far more interesting than any religious story. I've always been awestruck when considering the scale and complexity of the universe, the unimaginably slow movements of galaxies colliding, the strangeness of things close to absolute zero, etc etc etc. Religion is either largely or entirely composed of made up stories about people doing stuff.
"Hey, so god was going to flood the planet to kill everyone (because he loves us), but he didn't want all the animals to die so he had some guy build a giant boat to temporarily store 2 of each of them."
vs
The Hubble deep field.

No contest.

On the other hand, if there is a creator who will someday judge us and eternally reward or punish us, may it have mercy on my foolish blasphemous self. Also, some irrefutable evidence for your existence would be nice pleasedon'tsmiteme.
