If you extrapolate, by the time I have as many posts as you, I'll have more than 50 thank yous, whereas you only have 11.You really don't want to go there.

Here's a mathematical concept for you. If you extrapolate, by the time I have as many posts as you, I'll have more than 50 thank yous, whereas you only have 11.
Yes agyejy, counting thank yous is another subject isn't it?
I asked you to leave me along several months ago at another site. You relentlessly follow me around spouting nonsense science, all the while telling me I don't know what I am talking about. You're the one who wants to go there. I'm just following your lead. If you don't want to interact with me, I suggest you engage someone else in a conversation and quit your whining.

See, when you run your mouth without saying anything, your number of posts goes up, but your number of thank yous stays the same. Would you like me to write you an equation to demonstrate this relationship?
I watch Brian Greene and Leonard Susskind videos on YouTube as a supplement because I want to understand this subject better.

I've had the opportunity to watch a couple of Susskind's videos myself and I rather like his logic regarding black holes. Whereas the former viewpoint regarding the loss of information held by Hawking and Susskind's position that all information is stored at the event horizon I find very appealing myself. Even so, I still have some reservations because theory says that as a black hole grows larger, it's entropy decreases as it's mass increases. When considering Black Hole thermodynamics, how do we reconcile these two opposing positions? The increase of information will also increase the degree of entropy.

When considering Black Hole thermodynamics, how do we reconcile these two opposing positions? The increase of information will also increase the degree of entropy.In the information theories that I am aware of the entropy of information is actually opposite in sign to the standard entropy of disorder. So a growing black hole is expected to decrease its disorder entropy as the information it stores increases.
Interesting, do you know the explanation for this assigned negative entropy? I always thought that any added information to a closed system increased it's entropy. If you have a link to this information, I would gladly check it out. Thanks......
I actually did some quick calculations showing that electron-electron scattering in a metal is negligible and that electrons in metals scatter off things like impurities and phonons much much more often.
An object that is swallowed by a black hole decreases the entropy of the universe since the event horizon is impenetrable from the inside. However, the increase in entropy of the black hole itself more than makes up for the loss. So in general the entropy of the universe increases. The surface area of the event horizon is proportional to the entropy of the black hole as determined by Jacob Beckenstein. This then led on to the development of the holographic principle.

I disagree with your statement about entropy in black holes increasing as they grow larger. Gas in a bottle is "order." Open the lid and let it out, that's disorder. Black holes put the gas back in the bottle. There's nothing more ordered than a bunch of mass and energy that's been merged into a simple plasma soup at a point particle location.
That's nice, but Beckenstein has never actually observed the inside of a black hole to confirm this. I still say, there's nothing more ordered than a bunch of mass and energy that has been confined to a point particle location and turned into a simple plasma soup. Gas in a bottle is order. An open bottle with the gas spilling out to fill a room is disorder. Black holes are bottles. The Big Bang is what happens when the bottle gets too full. Big Bang Nucleosynthesis is the reverse of what happens in a black hole.
By the way, the most obvious contradiction that leads me to have faith in what I just said is the apparent "finite" nature of the universe. It's a contradiction that entropy is only one way. It's a contradiction that the universe had a "starting point." Mass and energy don't just appear out of nowhere. The object that became the Big Bang had an origin. The universe didn't just spontaneously appear 13.7 billion years ago. Mass and energy cannot be created or destroyed. Entropy seems to imply the ultimate fate of our universe is heat death and dissipation. How can that be? Time started at the Big Bang, ends with heat death? The universe came from nothing, ends as nothing, it is a blip in nothingness, surrounded at both ends by no time? That's a contradiction plain and simple. My "black holes recycle entropy and the universe" hypothesis makes more sense than that, by a huge factor. In this case, I am far more tempted to believe my own logic than Beckenstein's math.
I just double checked the equations for black hole entropy and confirmed they are directly proportional to surface area. Which means the entropy of a black hole actually increases as it grows. I'm not sure where you got the impression that the entropy of a black hole decreases as it grows. Do you have a link to something that says this?I apologize for vague incorrectness of my earlier post.
Here is a problem. Take the function f(x) = x sin 1/x and find the limit as x approaches zero. Then consider how to trace the function through the origin.EDIT: What can this demonstrate to us that may shed light on the problems associated with black holes?
If you had researched the equation instead of guessing you would have found that when plotted the function describes a sine wave that changes in magnitude with distance and that it is impossible to trace the function to the origin at 0,0. This is because as the function decreases in magnitude the wavelength shortens in an infinite sequence of steps. This can appear to mimic the time dilation around a black hole. The surprising thing is that as the wave is blue-shifted and the energy increases time slows down. Which when you consider it properly makes sense as things that are vibrating VERY fast will have less chance of interacting on shorter timescales. Therefore time dilation. The fact that gravity blue-shifts waves is then the ultimate reason for time dilation. The most important factor is then not the geometry of space-time but how the stresses affect wavelength.
