"The simulations tell us that you cannot take the matter in the early universe and line it up in strings this large. There simply hasn't been enough time since the Big Bang for it to form structures this colossal."

That's quite interesting.  It once again shows we don't know everything, despite our best attempts.

10,8 billion ly? That means 10,8.10e9 or 10e12? For last I knew was that radiotelescopes found the known universe to be wide about 6.10e10 ly. Well, I'm no expert for it, but I think our time counting should be revisited.

[Dude_Doc]

We'll probably find more material out there to proove that the universe has been around for some time. Maybe there wasn't just one big bang, but more and smaller? Or perhaps there are galaxies that can develop/grow faster, just like that desease that humans have.

I dont usually fully trust groups like cnn to give me details on scientific matters. THey often oversimplify and say things that are not full truths. It also causes the "expert syndrome" where people read these articles and proclaim themselves know-it-all's based on laymen's articles like this.

[Sardauker-Kirov]

Yes, and second.... They only bring in the theory thrash and hell, how many of this theory crap exist nowadays?

The Galaxy is too complicated for humanity right now, with our present technology. Sure we could observe the black holes, galaxies, quasars etc etc.

But we will never fully understand them, until if we reach and get solid proof from them up close.

( Hell, I won't get close to the black hole even if they offered me the money of the world. )

[Acriku]

It's interesting how you disregard founded theories without much thought to them, and bask in theories of your own with the same commitment to thought.

[Dude_Doc]

No one would ;) .

[Scrinlord]

I would ::)

or not.

But yeah, the universe I think is WAY to complicated for human understanding.  I dont think that we will ever come close to unlocking the secrets of our own galaxy, much less the universe.

[Acriku]

Says who, Scrinlord? That's completely unfounded.

[Scrinlord]

says me.  Its just my opinion.  I believe that the universe is infinitly to complex for us to ever figure out everything we need to know about it.  I did not quote some scientist or anything, its just what I think.

[Nyarlathotep]

I kinda tend to agree with Scrinlord. IMO the galaxy is way to huge for us to understand what happened and what's going to happen. I'm not saying we won't find/accomplish anything, but certainly not all..

[Sardauker-Kirov]

Theories are theories, not facts Acriku. And what I am saying about my OWN theories( Did I even made a theory? Cough... ::) ) aren't facts either. Everybody has their own view or theory about some things and I'd rather stick to the theories that fits my views best.

[TMA_1]

the word theory is thrown around way too much. A theory is not an idea! an idea is simply the beginning of the scientific method. Do you have some sort of evidance? Do you have an idea that fits with certain mathematic and scientific foundational ideals? Not even that, does your idea have capabilities to refute those foundations? If so you make it a hypothesis. An idea with merit that should be studied. Once studied with extreme detail, and the idea goes through the massive testing with near perfect results, it becomes a theory. A theory is an idea that has a very real posssibility of being "truth" if you can use that word at all. It has merit and can be applied with, or used to refute other theories. Dont just throw that word around kirov.

[Acriku]

Of course, not many people know the difference (significant in fact) between a social theory (a guess made by a person after observing a phenomenon) and a scientific theory (an explanation of a phenomenon, grounded by as many facts and evidences as any law and principle. There is no heirarchy of certainty concerning scientific theories, scientific laws, and scientific principles. So your assessment is false.

[Sardauker-Kirov]

If it is about the blackholes, there are some facts like the great concentration of gravity that is so strong, it bends light and space.

But most of the things are unknown about the blackhole, like what activity is going on in the center. They have theories about that the law of physics, including time and space -- ends inside the blackhole.

People can have their own theories about the object, even if they think the target can have purple loveable ponies or whatsoever.

A theory is a theory.

[Acriku]

Actually, you're applying one meaning to both usages of the word "theory." A social theory is a social theory, and a scientific theory is a scientific theory. This is basic knowledge, you should get to know it well.

[TMA_1]

I heard a neat hypothesis being worked out mathematically now that says black holes are rips in space-time (nothing new) but that when things get closer to the black hole, the slower they go, until at the very end they go so slow as to be caught up forever in one central area, (which is the event horizon).

(that leads me to something, I know this is a different subject but could somebody help me here? There are a lot of models of "black holes" but they usually show a disk swirling towards the black hole, with stuff flying out at near light speeds like a funnel. I always looked at it like a three dimensional model, that it isnt just a flat disk but a "sphere" of sorts, it isnt a sphere, but the mass of matter forms around it in a blob, and from a distance it might look simply like a difuse star. So dim though that we cant see it till we are very close. Like the accompanying star at alpha centauri that cant be seen with the naked eye because it is so dim.  basically if you were close enough (yikes) it would look like a nebulus star, diffused all around the spherical parimeter)

A theory is a theory. It can be both scientifical or social, etc. But the definition remains...

Well, a Black hole would likely be orb formed, since it's a dead star. But the activity around a blackhole is quite unusual. They say it spins around like a whirlpool, but there is also activity above and beneath the black hole.

Some theories stated the things you've said; If a person fell down in a black hole, he'll go faster at a slow pace that increases with each second. However, the guy that is outside the black hole will see the person that falls into it, travel very slowly.

[Acriku]

You obviously don't have a good stronghold in basic science. Look, a scientific theory is a theory that explains a phenomenon, and is neither more certain nor less certain than a law as laws describe the phenomenon, while theories explain it. A social theory is what people use everyday - they find a glass of milk spilt on the floor, so they say - "Here's me theory, the cat did it." It's a guess, in social terms. But in scientific terms, a theory is most certain to be true.

[Sardauker-Kirov]

You're right about that.

But t'is still possible to have a hybrid between the two types.

If you have alot of knowledge about Gravity for example and you see a object that isn't scanned completely.

Now if the object has alot of gravity just like the black hole and if you know the possible effects that comes with it, you can make a guess, thus, making a mini-theory.

Not much of a theory, but still a small theory if you have enough knowledge about specific topic.
