Man I really hope someone figures out how to cover 78 billion light years of distance in shorter time (and I hope Im around to see it). I want to know whats over there!

I am with you on that one, I really want to know what else is out there. We need to find some way of becoming immortal , I would love to see how our world progresses and what else we discover about the universe

I say it every time someone brings up these photos - if this wows you, please pick up and read the hardcover version of "Pale Blue Dot" by Carl Sagan. He pulls deeply on the hubbell images - brilliant!

I seen a youtube video about Pale Blue Dot, didn't know it was based on a book. I might have to take a look for it next time I am at Chapters.

Wow...as a scientist, I am very, very humbled. Speechless. In awe.

A little closer to home the Mars Rovers are coming up on 4 years service. Not bad considering they were thought to only be good for 90 days.

Mars Rover Finding Suggests Once Habitable Environment
By KENNETH CHANG
Published: December 12, 2007
SAN FRANCISCO — The lame wheel on the NASA Mars rover Spirit has proved an invaluable science tool, turning up evidence of a once habitable environment, scientists said Monday.
Meanwhile, images from the Mars Reconnaissance Orbiter have largely unraveled the mystery of geological patterns called “spiders” that appear each spring around the south pole.
The scientists reported their findings here at a meeting of the American Geophysical Union.
The right front wheel of Spirit stopped turning in March 2006. Since then, the rover has been driving backwards, dragging the lame wheel along. This May, scientists noticed a bright spot in the trail of overturned dirt.
They turned Spirit around for a closer look, finding high levels of silica, the main ingredient of window glass. They then aimed the rover at a nearby rock, wanting to break it apart to determine if the silica was just a surface coating, or if the rock was silica all the way through.
The target rock survived Spirit’s charge, but a neighboring rock cracked open. The interior of that rock, which the scientists informally named “Innocent Bystander,” turned out to be rich in silica.
On Earth, such high concentrations of silica can form in only two places: a hot spring, where the silica is dissolved away and deposited elsewhere, or a fumarole, an environment, often near a volcano, where acidic steam rises through cracks. The acids dissolve other minerals, leaving mostly silica. On Earth, both environments teem with life.
Spirit’s twin, Opportunity, which has been exploring a spot on the other side of Mars, has found evidence of an environment once steeped in acidic groundwater. The silica discovery is the first time that Spirit has seen signs of widespread water in its surroundings, a 90-mile-wide impact crater known as Gusev Crater.
Gusev was chosen as a landing site, because, at least from orbit, it looks as if it were once a lake with what appears to be river channels flowing away from it. However, until now, the rocks that Spirit has examined have largely been volcanic basalt with little hint of water.
“This shows us a side of Mars we haven’t seen before, and my guess is that it’s more common than we had thought,” said Steven W. Squyres, the project scientist for the rovers. “Whichever of those conditions produced it, this concentration of silica is probably the most significant discovery by Spirit for revealing a habitable niche that existed on Mars in the past.”
From far above the surface, the Mars Reconnaissance Orbiter has been taking a closer look at radial patterns of “spider” gullies, as well as bright and dark fan-like features that appear in the Martian landscape each spring.
Scientists first spotted the gullies several years ago in images taken by the Mars Global Surveyor. With the much higher resolution of Reconnaissance Orbiter, scientists saw for the first time that the gullies were wider at the center of the pattern. Another instrument allowed them to map the images onto the Martian topography; the centers of the spiders were at the top of the small hills. Those two bits of information indicated that the gullies were carved by something flowing uphill — and that pointed to carbon dioxide.
At a news conference on Tuesday, Candice Hansen, deputy principal investigator for the orbiter’s high-resolution camera, said it now appeared that a layer of translucent carbon dioxide ice, perhaps half a yard thick, formed over the south polar terrain during the winter months.
In the spring, sunlight warms the ground, vaporizing carbon dioxide at the base of the ice layer. The gas flows uphill, carving channels in the underlying soil. At weak points in the ice, the gas erupts in small geysers. The release of pressure causes the carbon dioxide gas to freeze solid and fall as white snow — the white parts of the fan-like patterns. Dust blown out with the carbon dioxide falls on the ground to form the dark parts of the fans.
“It is unlike anything on Earth,” Dr. Hansen said, though similar patterns have been seen on the Neptunian moon of Triton.
Man I really hope someone figures out how to cover 78 billion light years of distance in shorter time (and I hope Im around to see it). I want to know whats over there!
what happens after 78 billion years away though? does it just end like a wall?

A mirrored universe, where everything is opposite. You have an exact opposite there....looks just like you, only does/likes everything just the opposite of your likes/dislikes.
duh....just a theory....I think it came from an old twilight zone eposode maybe?

Just as there are multiple stars and multiple galaxies, there can also be multiple universes. We are not even a fly speck on the record of time and space.

The mathematics of string theory demand at least 11 dimensions, I believe. So even in all this vastness we may only be seeing 3/11 of what's really going on. In just this one universe.
My brain's gonna assplode.

What if our universe is just another in billions, like planets are in our perspective? And then again this group of universes could be part of billions more of its kind, and it could keep on infinitely. Fascinating stuff.
About the wall thing though, in my mind it makes sense that when you reach the end you start back on the other side - like going in circles, only in a multi-dimensional way.
Edit: If the going in circles thing was to be true, then does that mean that the entity succeeding the biggest and last group of entities is the smallest entity? That would mean that something smaller than a grain of sand would hold everything in it! Now that's crazy stuff.
I can't stop watching that video, but I went and checked out the wiki entry for HUDF and found this pic. Pretty stunning.
But you really, really, really have to check out the full size version to fully appreciate the scale. If they could focus on a blank space on this pic they'd probably find as many more that much further away, and again from there.
