Okay. So our galaxy, the Milky Way or in Greek-Calico galaxy, is a wondrous yet horrible piece of work. The Milky Way is approximately 100,000 light-years in diameter. Meaning it would take us 100,000 years, traveling at the speed of light, to travel from one side to the other.

Anyway, our Milky Way is unique in a way that it is a Spiral-Bar galaxy. Meaning it has a bar across its' center.

But-I thought we had a black hole at our center? Right?

Apparently, we do.

But how is this "bar" possible. Anything that gets close to a black hole gets sucked into infinity. But there are 30 million stars in this bar.

What? Both are true.

I want to know how. Anyone got answers?

The only thing unique about a black hole is its density. If our sun magically turned into a black hole without going through the whole supernova thing first, the planets' orbits would be completely unaffected. Just think of a black hole as a very large, dark sun with no volume and everything becomes clear. And really... that's what a black hole is.

In short, they're just orbiting the hole.

Also, I'm moving this to the CB forum, for lack of gun-relatedness.

Just like how all the customers orbit around my sisters hole. xd

Your sister's a prostitute? neutral

Well technically right now the b***h is more of a slut, but I wouldn't be surprised if she became a prostitute.

I had an interesting thought for you guys. You know how everyone's looking to Mars as the future? I think otherwise. I think I know a way to terraform Venus that would only take time (lots of it) and money (more of that). We could do it with current technology.

First, you land a ship on Callisto. Then it either builds or installs a pre-built rocket motor. Fly the entirety of Callisto to Venus, and park it in orbit. Wait a couple thousand years, and voilà! Earth-like and rocky. Maybe even oceans. Then just seed it with bacteria, wait a hundred years, and seed it with algae. Keep going up the food chain every hundred years or so until Venus is as lush as Earth.

See, the problem with Venus is the clouds, right? They insulate; trap the heat in. Earth would be like that too, if we didn't have the moon to strip away excess atmosphere. So how do we fix Venus' cloud-cover problem? Give them a moon. Venus is a touch smaller than Earth, and Callisto is a bit bigger than the moon, but that's nothing that can't be fixed with atomics.

They are also much closer to the sun so the direct sunlight would be much more intense.

I remember watching some DVD from Nova on black holes. I don't remember anything from it, but hey, I got $80 just for watching it and taking a survey.

It would be warmer, true, but they're still within the habitable band. It might be an interesting experiment as to what Earth would have been like if it'd been a few degrees warmer. Worst case scenario, the equator is a wasteland. Then, evolution! Natural selection breeds hardier species to take over the well-lit, previously-uninhabitable sections of the planet.

Earth is 93 million miles from the sun while Venus is 67.2 million miles. I strongly doubt that that big a difference would make Venus inhabitable even to the toughest survivors on earth.

Although Venus is called the Earth's "twin," its surface conditions appear to be very different from those of the Earth. Geologists have had difficulty learning about the surface of Venus because the planet is always surrounded by thick clouds of sulfuric acid. They have used radar, radio astronomy equipment, and space probes to "explore" Venus.

Until recently, much of what geologists knew about the surface of Venus came from ground-based radar observations, the Soviet Union's Venera space probes, and United States Pioneer probes. In 1990, the U.S. space probe Magellan began orbiting Venus, using radar to map the planet's surface.

The surface of Venus is extremely hot and dry. There is no liquid water on the planet's surface because the high temperature would cause any liquid to boil away.

The temperature of the uppermost layer of Venus's clouds averages about 55 degrees F (13 degrees C). However, the temperature of the planet's surface is about 870 degrees F (465 degrees C), higher than that of any other planet and hotter than most ovens.

If we were to somehow inhabit Venus we had better get a hell of an air conditioning system installed. Even if we could get the clouds to go away that wouldn't cool it anywhere near livable conditions.

Considering that was probably found in a scrap yard I'm sure we can get it for a reasonable price. biggrin
