Hawking is right about the wave-function of the universe producing the Big Bang. There is one "tiny" problem though if he wants to use this to argue that God doesn't exist:


He neglects that zero doesn't mean "nothing", it just means "balance". That balance could have been from the first possible particle that broke apart producing charge which led to energy which led to atoms which led to matter which led to gravity which led to ... us. And where did that first particle come from?

The nature of gravitational attraction and repulsion is actually a little different from electromagnetic attraction and repulsion. Here's the deal:

Electromagnetism

+ charge and - charge: attraction, causing mutual centripetal acceleration
+ charge and + charge: repulsion, causing mutual centrifugal acceleration
- charge and - charge: repulsion


Now here's the funny part...

Gravitation

+ mass and + mass: attraction, the centripetal gravitational force we're all familiar with
- mass and - mass: attraction, but the masses accelerate away from each other (I'll explain below)
+ mass and - mass: pursual, with the two masses accelerating off in a straight line to infinity


Now, to explain the last two...

I'm sure you know all about F = ma (force = mass x acceleration). Well, when you have two negative masses, (-m), the gravitational force between them is positive (+F), which means, technically, the force is still attraction. But, to cancel out the other negative sign, the acceleration will be negative (-a). This causes the masses to accelerate away from each other.
Put simply, negative mass is negative inertia, so positive forces cause negative acceleration.

A positive and negative mass is a combination of the first two cases. The negative mass accelerates toward the center of the positive mass, but the positive mass accelerates away from the center of the negative mass. The result is the negative mass will chase the positive mass off to the far reaches of the universe, constantly accelerating the whole way.

Yes, I was inferring that perhaps there is a closer bond than we are presently aware of, that perhaps they are more interconnected than our present knowledge would lead us to believe.... looking for the "unification" of them in some way. Sorry to have been fuzzy on that part.

I knew what you were getting at...I just took the opportunity to explain a couple things: 1) that the simple push-pull of electromagnetism doesn't really translate to gravity as easily as some people would like it to (the two are similar, but fundamentally different); and 2) just the really cool nature of attraction/repulsion when dealing with positive and negative masses.

The second one was really my intention. I thought people might be intrigued by the idea of two masses chasing each other around the universe.

ahhh gotcha! It was an excellent explanation too, very straightfoward, I'll give it two thumbs up!

A black hole is a black body - meaning every photon (and therefore any particle at all) that falls on its "surface" is captured by the black hole. This means two things:

1) all matter that comes into contact with the event horizon will be captured and fall into the center of the black hole. The more matter is captured, the bigger the black hole gets. Of course the black hole isn't infinite, but it doesn't need to be - if a black hole were ever able to capture an infinite amount of mass, then the resultant black hole would be infinite...but seeing as how this is a physical impossibility, it's not something that could actually happen.

2) since a black hole is a black body, it emits black body radiation, called Hawking radiation. This is true of all black bodies. Even stars, which are approximate black bodies do this (though the black body radiation they emit is overwhelmed by their natural luminosity). Also, the Cosmic Microwave Background is a near-perfect black body spectrum, since it represent light emitted by the universe at a time when it absorbed all light that existed within it.

This is putting into words something that is beyond human comprehension.

If my theory is correct then it certainly isn't beyond our comprehension. Your vague theory probably would be though.

Ouch.

You are forgetting Twilight, Neutral, Warm, Androgynous, and Present, the thin line that links opposites.

The holy trinity, the third being the sum of the other two. Hot and cold you get warm, past future and present, father mother child, earth sun moon, X Y Z axis and so on. Seems to be the nature of our reality as we see it, but obviously there is much more to it than this.

Check out The Urantia Papers, interesting stuff in there about the creation of the universe, such as Lucifer being the creator of our reality on the basis of the idea of separation or opposites, in an attempt to imitate the Creator without the Creators help. If you ask any hardcore Satanist if there is a Hell they will say no, we are already on the lowest level.

All matter can not fall to the center of the black hole if the black hole is a sphere. How can it? The sphere proves that it dosent.

The black hole is defined by its event horizon... that's what's spherical. The event horizon is the distance from the center at which the gravity becomes so strong that nothing - not even light - can escape. But there is nothing physical at this distance, it's just a specific strength of the black hole's gravitational field. Further out and the black hole's gravity is too weak to capture all light... closer in and the gravity gets even stronger, right in to the center, where all matter that falls into the black hole goes.

So, yes, all matter goes to the center of the black hole.
Technically, the physical structure of the black hole is a point in the middle of the spherical event horizon, called the singularity. This is what all matter falls into.
