This problem is dealt with (in the context of classical General Relativity) nicely in Taylor & Wheeler's book "Exploring black holes: An introduction to General Relativity" (2000, Addison, Wesley, Longman). In the section entitled "Project B: Inside the black hole" they perform a calculation for a free-falling observer, based on the Schwarzschild metric ...

Answer to question Version 1: No one knows. We can answer this question using general relativity to give a classical description but I think there is now serious doubt that GTR describes the inside of a black hole (i.e. within the event horizon) accurately and that we shall need a full quantum theory of gravity to know what happens there. But the classical ...

Taking this as a matter of Fermi estimation, I will take the Newtonian form of gravity. No, this isn't great accuracy, but if anyone has any severe theoretical issues to raise, I will be glad to hear them. I will assume that your body extends 1 m out from its center of mass and that the extremities there will experience 10 g before your fingernails bleed and ...

Take a piece of meat of 100Cal and almonds of 100Kal and a crystal of sugar of 100Cal. Which has the lower entropy at the same temperature? Certainly the crystal, because it is the most ordered. Then in ordering come the almonds , which has a simpler composition of molecules and higher density. Meat has blood, mitochondria, cells, nuclei of cells . This ...

This would depend on what entropy of plant and animal is supposed to mean. Originally, entropy describes systems in states of thermodynamic equilibrium. If you want to introduce similar quantity for systems in more complicated states, (plant or animal are not systems in thermodynamic equilibrium), you need to give its definition. There is no universally ...

Boltzmann's formula for entropy is S = k * log W, where S is entropy, k is a constant, and W is the total number of ways the micro particles of a system can be re-arranged without altering the macro appearance and properties of the system. What Boltzmann had in mind was a gas tending toward thermodynamic equilibrium. For any other system, the measurement ...
