Discussion Overview

The discussion revolves around the concept of converting mass into charge, exploring the relationship between mass, charge, and energy. Participants also touch upon related topics such as the nature of black holes, the behavior of light, and the unification of gravitational and electromagnetic forces.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant suggests a "crazy idea" about the possibility of converting mass to charge or vice versa.
  • Another participant argues that mass and charge are inherently linked, stating that you cannot have charge without mass, and emphasizes the conservation of energy and charge.
  • There is a discussion about black holes and their effect on light, with some participants noting that gravity can affect electromagnetic waves.
  • One participant mentions that truly black objects absorb all light, while others clarify that most black objects only partially absorb light.
  • A participant raises a question about the interaction between gravity and electromagnetism, suggesting that phenomena related to black holes might be relevant.
  • Another participant questions the idea of unifying gravity and electromagnetism and states that light does not diminish unless it interacts with something.

Areas of Agreement / Disagreement

Participants express differing views on the possibility of mass converting to charge, with no consensus reached. There are also varying interpretations of the nature of black holes and the behavior of light, indicating ongoing debate.

Contextual Notes

Some claims about the relationship between mass, charge, and energy are not fully resolved, and assumptions about the definitions of terms like "black" and "light" may vary among participants.

Who May Find This Useful

This discussion may be of interest to those exploring theoretical physics, particularly in the areas of particle physics, general relativity, and the unification of fundamental forces.

if something is black in color, that means it doesn't reflect light(photon)?
where do this light got?

also for black hole
why people say that the gravity of black hole is so strong the light cannot escape?
Is it means that gravity can affect em wave?Thank you~


Of topic problem...
(crazy idea)
is there any process that mass converse to charge or the reverse case?
THz

mass converting to charge doesn't really make a whole lot of sense. An electron, for example has both mass and charge. You can't have charge without mass. However, mass can be converted to energy and energy can then convert to particle pairs (like a positron and an electron). However, energy AND charge must always be conserved so you can never create an imbalance of charge.

As for black holes, yes gravity effects light. That is what general relativity is all about (space-time distortion and such). You may be confused because you may have learned Newton's law of gravitation which is only dependent on mass (and light has no mass). However, despite being an excellent approximation Newton's view of gravity is wrong and was replaced by einstein's theory of general relativity.
 
As for the color black... Yes, TRULY black things absorb all light (this light energy usually goes into heating the object up which is why when you were a black t-shirt out in the hot sun you get hotter than a white t-shirt). However, most things that we call 'black' are only partial absorbers, they reflect some back (which is why most things that are 'black' don't, truly, look like darkness). However, since they play no favorite with which light they reflect (which is how other things acquire color) and because they absorb a chunk of reflecting light, they look black.
 
Black is the absence of light, so you are correct. Intruding photons are either absorbed or pass right through. Black holes do forbid photons from escaping from inside their event horizons. Photons are, however, freely emitted from matter approaching the event horizon of a black hole. White holes? Highly unlikely based on observational evidence.
 
Welcome to PF, anson !

Enjoy your ride. You will find many things here.
 
thz everyone
actually, l am thinking of something crazy.
To unify gravition and em , we need some phenomenons of the interaction of gravition between em. Black hole affect light. Can this be the right phenomenon for the interaction of gravition between em? Actually, is there any more phenomenon?

Another problem about light is that will light die out if light don't experience any reflection?

I don't know what you mean by unifying gravity and em. And no, light does not diminish unless it comes in contact with something.
