So we have an interesting picture of this planet now. It’s roughly the same size and mass as Jupiter. It’s flippin’ hot, so hot that water in its atmosphere is in the form of steam, and drops of molten magnesium silicate may rain down. It has hellish winds, whipping the atmosphere into a frenzy (and probably driving that magnesium silicate rain sideways, not down). It withstands periodic outbursts from its parent star that can blow 1,000 tons of its atmosphere away every second. We even can figure out that it has lovely sunsets.
And it’s blue. Even from 630 trillion kilometers away, the color of this planet literally still shines through.
Today marks a historic milestone for mankind, Voyager 1 has entered Interstellar Space.
Thirty-six years after it was launched from Earth on a tour of the outer planets, the plutonium-powered probe is more than 11 ½ billion miles from the sun, cruising through the vast, cold emptiness between the stars.
Also comments from some big space geeks.
Also very interesting to know this holds the Golden Record which includes many sounds and images selected to portray the diversity of life and culture on Earth, and are intended for any intelligent extraterrestrial life form, or for future humans, who may find them.

[QUOTE=Max Cow Disease;3809131]Stephen Hawking's babbled about this from time to time. He figures that it's nearly impossible that there is not extraterrestrial life out there in some form, and likely in many forms (interestingly enough, he also advises that we avoid contact with any such life).
"Theorists" sounds like a perfect job to get really baked for.

It makes more sense to me than the normal "big bang" theory. maybe 20 billion years ago a HUGE black hole ate an old universe,blew up and spit out a new one. maybe dark matter is a reminisce from black holes.
Dark matter aside(not understood or realy even proven yet) pretty much everything happening in the universe can be explained by physics but the big bang theory is off the charts IMO.
Isn't saying "Dark Matter aside, we have a good understanding of the universe" kind of like saying "well besides the sun, we got a pretty good understanding of our solar system"?

Not really. According to NASA, ~27% of space is dark matter. We have a decent understanding of everything else, and we're slowly learning more & more about dark matter. You don't need to be an expert on dark matter to be an expert on other aspects of the universe.

Nope, Stars, Planets, Galaxys and even Black Hole formations are easy to explain with physics.
Coming up with 200 billion galaxys with trillions of stars/planets from something the size of maybe one atom breaks all laws.
