Hawking Radiation: Understanding Its Behavior & Questions

AI Thread Summary
Hawking radiation is explained through the creation of virtual particle-antiparticle pairs in quantum mechanics, which occur randomly throughout the universe due to the uncertainty principle. The intense gravity of a black hole's singularity can capture one particle from this pair, allowing the other to escape as radiation. This process leads to the gradual dissipation of the black hole over time, adhering to the law of energy conservation. Questions arise regarding the behavior of charged particles: if a positively charged particle is absorbed, whether its antiparticle is emitted as 'negative energy' and if this would negate the positive energy inflow. Additionally, the discussion touches on how virtual particles, despite having no mass, are influenced by gravity, as evidenced by the bending of light around massive objects. The conversation suggests a deeper understanding of these phenomena may be gained through concepts like the Penrose Process.

my understanding of the behavior of hawking radiation (with questions) is as follows:
1) in Q. Mechanics virtual particle/antiparticle pair are created randomly throughout the universe.
Q1) without a complete layout of Q.M., why is this?

2) the gravity of a singularity will remove one of the pair, leaving the other to be emitted as radiation. thus by the law of energy conservation an inflow of positive energy dissipates the black hole in time.
Q2)if a positivly charged particle is taken in will its antiparticle pair be radiated as 'negative energy'? and if so wouldn't this cancel the effect of the inflow of positive energy? or does +/- energy not anniparticle annihalate each other as does +/- matter? also, how can a virtual (no mass) be effected by gravity? (i know it does because we observe light (photons: virtual particle)bend over high gravity areas.)

Uncertainty principle.

It is a lot more subtle than the above description. Good starting point is understanding so called Penrose Process.

I need to calculate the amount of water condensed from a DX cooling coil per hour given the size of the expansion coil (the total condensing surface area), the incoming air temperature, the amount of air flow from the fan, the BTU capacity of the compressor and the incoming air humidity. There are lots of condenser calculators around but they all need the air flow and incoming and outgoing humidity and then give a total volume of condensed water but I need more than that. The size of the...
Thread 'Why work is PdV and not (P+dP)dV in an isothermal process?'
Let's say we have a cylinder of volume V1 with a frictionless movable piston and some gas trapped inside with pressure P1 and temperature T1. On top of the piston lay some small pebbles that add weight and essentially create the pressure P1. Also the system is inside a reservoir of water that keeps its temperature constant at T1. The system is in equilibrium at V1, P1, T1. Now let's say i put another very small pebble on top of the piston (0,00001kg) and after some seconds the system...
