Space is truly awsome. I mean just the thought of us going around doing our little daily lives, worrying about this and that when theres so much more out there. It just amazes me.
 
It's hard to imagine how 17th century explorers looked upon the Americas the same as we look upon space today.
 
Want to know what would suck? If someone was immortal and get's launched into space and is stuck floating there for the rest of eternity.

imagine what youd see.. as long as you were going like 9 bagillion miles an hour.

What would suck, is if that person got sucked into a black hole and was reduced to nearly nothing.

you wouldent get sucked into a black hole, youd just be ripped in two. or many more pieces, or just pulverised.

but then you'd be very, very massive :O

:D

Cool though :)

Ripped in two? Given that you are in space, what would attenuate the other half of you to cause the rip?

I can assure you, would be sucked in 'cleanly', and simply compressed into an extremely small particle.

no, because 1 part of you would be sucked into it first, whether its your leg, or head or something would have to enter the (centerpoint? nexus? i forget) and part of you would have to enter later.

matter, i.e. hydrogen would compress into very dense particles, yeah. but it doesnt take the entire mass, and magically transplant it into the black hole, it sucks it in a line, thats why you see the outside of stars next to blackholes have the line of their coronas leading to the blackhole.
 
Gah.. I was expecting a picture of a space rock.... got my hopes up and everything.. I hope HL2 isn't a disapointment like this :(

That may be true, but we're talking a much smaller object with practically no mass to contend with the pull of the blackhole.

Also, you'd actually become an ooze.

doesnt matter what object it is. our pink fleshy bodies would get pulverised, yeah as i said. no one really knows what its like past the event horizon, but i wouldent mind finding out. could be a hell of a trip.
 
Is it possible to teleport to another area if you were in a black hole? Do they always destroy?

probably, but no one knows, black-hole physics are different from ours. but it'd be nearly impossible not to be obliterated by the tidal forces before you enter a black hole. so it's kind of a silly question.
 
Just remember that you're standing on a planet that's evolving
And revolving at nine hundred miles an hour,
That's orbiting at nineteen miles a second, so it's reckoned,
A sun that is the source of all our power.
The sun and you and me and all the stars that we can see
Are moving at a million miles a day
In an outer spiral arm, at forty thousand miles an hour,
Of the galaxy we call the 'Milky Way'.
Our galaxy itself contains a hundred billion stars.
It's a hundred thousand light years side to side.
It bulges in the middle, sixteen thousand light years thick,
But out by us, it's just three thousand light years wide.
We're thirty thousand light years from galactic central point.
We go 'round every two hundred million years,
And our galaxy is only one of millions of billions
In this amazing and expanding universe.

The universe itself keeps on expanding and expanding
In all of the directions it can whizz
As fast as it can go, at the speed of light, you know,
Twelve million miles a minute, and that's the fastest speed there is.
So remember, when you're feeling very small and insecure,
How amazingly unlikely is your birth,
And pray that there's intelligent life somewhere up in space,
'Cause there's bugger all down here on Earth.

Its possible it could dump you into another universe...but you'd still be either a super-dense particle or an ooze.
 
seeing that picture makes me want to get launched into space with 5 years worth of food and just fly around looking at things and eating until i die, then i will jettison my body into space and it will float forever... awesome :)

-merc

I was hoping for a space rock as well. What do I get? A picture of a piece of the universe. Damn it :(

HL2 is gonna suck now ;(
 
It looks more like a space sponge. The bump mapping is dissapointing, also.
 
This is why its a shame people aren't more willing to learn.

Anyone have any idea what that music was?
 
So, thats how to kill Superman!

Throw him into a black hole!

I am a Genius!
 
It's very odd seeing pictures of space, I find the whole concept very daunting - Those pictures were simply breath-taking - If it were possible, I would give a limb to travel to the "corners" of the universe, visiting all the planets and galaxies, I mean everything about us, humans - we're just the tiniest dot of a huge never-ending painting. Thinking about "infinite" is making me go nuts so I'll stop.

One day...

http://www.astrosurf.com/lombry/Images/hst-deepsky.jpg <--- this is 1 centimeter of space, (imagine your arm outstretched holding a 1cm cube) filmed with the hubble telescope. at one point they found over 10 thousand galaxies (each having upwards of 2 billion stars). if this doesnt help you realize how huge the universe is, nothing will.

Are you shure that 1cm of space is the correct term to use, don't they probably mean 1% or something, could you clarify that pleaze.
 
I said it once, i'll say it again! Quoted though cause i'm lazy.

When will you guys realize? Space is just a giant skybox. It extends out a small ways, then just STOPS. Unless you have noclip on.

All that stuff out there beyond pluto is just an incredibly detailed skybox, with several billions x several billions resolution bumpmaps. Duh!

PvtRyn: I actually imagined that picture as a cube (cm^3) that had been folded out like a map of the globe. Therefore, the galaxies are pretty tiny. Like somone had actually taken a cube of space & put it on Earth :D

it was music commisioned specifically for the "best of hubble" video. it was composed by richard pree, apparently (it says on the video). looks like he's the guy that runs news.com.au (maybe).

ok. the hubble was focused on an dark area of the sky (to our own eyes) for one week, allowing as much information and light to pass into view as possible.. basically, from earth, this is a picture of 1cm of the sky, as we see it, and in just that area they found 1,500 galaxies.
 
Its when you see presentations like that, you realise that it is arrogant in the extreme to assume we're the only sentient life forms in the universe. What a beautiful link, thanks.

Hopefully within my lifetime that question will be answered :(

Just to make everyone happy...

What would happen to me if I fell into a black hole?
----------------------------------------------------
Let's suppose that you get into your spaceship and point it straight towards the million-solar-mass black hole in the center of our galaxy. (Actually, there's some debate about whether our galaxy contains a central black hole, but let's assume it does for the moment.) Starting from a long way away from the black hole, you just turn off your rockets and coast in. What happens?

At first, you don't feel any gravitational forces at all. Since you're in free fall, every part of your body and your spaceship is being pulled in the same way, and so you feel weightless. (This is exactly the same thing that happens to astronauts in Earth orbit: even though both astronauts and space shuttle are being pulled by the Earth's gravity, they don't feel any gravitational force because everything is being pulled in exactly the same way.) As you get closer and closer to the center of the hole, though, you start to feel "tidal" gravitational forces. Imagine that your feet are closer to the center than your head. The gravitational pull gets stronger as you get closer to the center of the hole, so your feet feel a stronger pull than your head does. As a result you feel "stretched." (This force is called a tidal force because it is exactly like the forces that cause tides on earth.) These tidal forces get more and more intense as you get closer to the center, and eventually they will rip you apart.

For a very large black hole like the one you're falling into, the tidal forces are not really noticeable until you get within about 600,000 kilometers of the center. Note that this is after you've crossed the horizon. If you were falling into a smaller black hole, say one that weighed as much as the Sun, tidal forces would start to make you quite uncomfortable when you were about 6000 kilometers away from the center, and you would have been torn apart by them long before you crossed the horizon. (That's why we decided to let you jump into a big black hole instead of a small one: we wanted you to survive at least until you got inside.)

What do you see as you are falling in? Surprisingly, you don't necessarily see anything particularly interesting. Images of faraway objects may be distorted in strange ways, since the black hole's gravity bends light, but that's about it. In particular, nothing special happens at the moment when you cross the horizon. Even after you've crossed the horizon, you can still see things on the outside: after all, the light from the things on the outside can still reach you. No one on the outside can see you, of course, since the light from you can't escape past the horizon.

How long does the whole process take? Well, of course, it depends on how far away you start from. Let's say you start at rest from a point whose distance from the singularity is ten times the black hole's radius. Then for a million-solar-mass black hole, it takes you about 8 minutes to reach the horizon. Once you've gotten that far, it takes you only another seven seconds to hit the singularity. By the way, this time scales with the size of the black hole, so if you'd jumped into a smaller black hole, your time of death would be that much sooner.

Once you've crossed the horizon, in your remaining seven seconds, you might panic and start to fire your rockets in a desperate attempt to avoid the singularity. Unfortunately, it's hopeless, since the singularity lies in your future, and there's no way to avoid your future. In fact, the harder you fire your rockets, the sooner you hit the singularity. It's best just to sit back and enjoy the ride.

The hubble is awesome. But there are lots more impressive pics it took...like the pics of black holes and other interesting things. ( And yes you can see a black hole with the hubble.)

yeah, as long as its near a host star, or a radiation filter which isnt as interesting :)
