"entropy is disorder" = outmoded theory??
The wikipedia article I quote below is confusing me. I followed the links to Frank Lambert's website, where he claims that Peter Atkins, in the 8th edition of his Physical Chemistry, has come around to Lambert's idea that entropy is not related to...
I mis-stated something in my previous post. I said gravitational force is proportional to distance from the center. It's actually inversely proportional. So if there was just a spec of mass at the very center, and if you could get very very close to that spec, you would experience very high...
Thanks for the link. I don't understand why general relativity has to come into it, but then I don't understand much about general relativity, in general.
Each little piece of the Earth contributes to the total curvature at any given point. The curvature at a given point is proportional to the the gravitational force at that point. At points in the interior of the Earth, the gravitational force is proportional to the total mass below that point...
I understand that magnetic force is a relativistic effect of electric force.
Is there a force which is the relativistic effect of gravitational force?
If a stationary observer sees 2 electrically charged particles moving parallel to each other at the same very high speed relative to himself...

There is an infinite sequence of partial sums (1, 1.4, 1.41, 1.413,...) approaching SQRT(2).
(a) The first term in the sequence is 1, which is a rational...
In the previous post I neglected to mention that I was talking about red-shifting due to a black hole.
When I said that I think the motion of the source doesn't matter, I should have said that I think the acceleration of the source doesn't matter. Very vast velocity of the source relative...
Have I got it right this time?
Red-shifting is determined by the difference between the space-time curvature at the light source and the observer's space-time curvature.
For the light source, all that matters is the distance from the center of gravity -- I think the motion of the source...
Kurdt: What is the formula for the amount of red shift seen by an observer at distance from the center of gravity R-1 when the source is a distance R-2 from the center of gravity? I've been searching the web for this formula, but so far I've only found it without the distance of the...
Although no mass reaches the center in finite time, the gravitational effects of the mass, as seen from outside the event horizon, are indistinguishable from the gravitational effects of a point singularity. If you could magically teleport to the center of a black hole, without waiting forever...
Thanks, Pete. I'm particularly interested in the part about time not stopping at the event horizon (from the free-fall frame). Most popular accounts of falling into a black hole have the observer getting hit with the "blue sheet" as he passes the event horizon. But if the free-falling...
Post #13 in this thread from Pete:
"For a free-fall frame the tidal forces are finite and time does not stop at the event horizon."
Is that not equivalent to "Pete said that both the tidal force and time dilation are finite for an observer free-falling through the event horizon"?
If an...
My question was whether that can be a finite tidal force and an infinite time dilation at a particular space-time position in one frame of reference.
Pete said that both the tidal force and time dilation are finite for an observer free-falling through the event horizon.
In the Rindler...
There has been a science-fiction novel with a similar theme - Larry Niven's Neutron Star.
I don't know but my guess is that the time difference between Earth's surface and Mar's surface would only add up to a few minutes per billion years.
I don't think the sppeding of time...
I don't know tensor calculus so this debate has gone way over my head. But I have one question: In any of these alternate co-ordinate systems, is there infinite time dilaton at the event horizon without infinite tidal force?
