I am just curious as to what the generally accepted ideas are about black holes.

Okay, I understand that the universe is expanding. I also understand that in 1998 Cosmologist discovered that the Universe is accelerating rather than decelerating. My question is: "By expanding, do they mean that the mass in the universe is becoming more spread out, or is space time actually...

Second Law of Thermodynamics So, since we have covered the First Law, What of the Second? I'm just curious to see if anyone knows. By adding that mass, the Entropy goes down. Second law says that Entropy wants to always go up. How do Black Holes keep from violating the Second Law of...

You could, before you start, tell your team mates that the person that see two hats of the same color say the opposite; everyone else should pass. That way 1:3 times everyone would answer the question wrong; however, 2:3 times only one person would answer and you would would win the prize. Is...

Okay, I understand that the r-coordinate in the Schwarzschild metric represents the reduce circumference. My problem is that the r-coordinate in the Kerr metric is NOT the reduced circumference! What is it? Somebody, please answer this as quickly and as painlessly as possible! Thank You

Could someone explain to me, in excrusiating detail, Hawking Radiation, to include Hawking math and steps leading to the formation of the equations used to define and descibe it. It would be much appreciated. THANK YOU!

You guys do realize that Schwarzschild's solution also utilized the boyer-lindquist coordinates, right?

Hey, I was wondering if someone could kindly explain to me everything they can about Boyer-linquist coordinates. I was looking at them and I think I saw something, but I'm not sure. So, someone please tell me everything about them. Thanks

Okay, is it possible to transform an "x-y" equation into a parametric "equation"? If so, how would I go about it? For example, if I am given the equation (x^2)/1-(y^2)/25=1, what process would I have to use to find the Parametric equations? Thank You.

I have been researching Feynman and his diagram and really can't find much on the Diagram itself. Could anyone tell me the mathematics and other concepts behind it in excruciating detail? Or at least a site I can find it? Thanks

I war right? Please post explanation.

Thanks Kurt? I assume that is your name. That is all I needed. Oh, and I'm not going to give it up. :wink:

If I'm given the parametric equations for a hypocycloid: x(t)=(a/n)[(n-1)cos(t)-cos[(n-1)t] y(t)-(a/n)[(n-1)sin(t)+sin[(n-1)t] how would I go about putting it into a function form r(\theta). There has to be some way to do it. What would it be? Thanks

Is it possible to transform a parametric "equation" into a polar equation? If so how would I go about it? Thanks for reading.
