AI Thread Summary
The mass of the disc remains unchanged when used in a disc player, as the energy output in the form of video does not alter the mass according to Einstein's equation e=mc^2. The energy produced from the disc is a result of the conversion of stored information into a visual format, not a change in the disc's mass. The question posed contains a misunderstanding of how energy and mass interact in this context. The disc's mass remains constant regardless of its function in the player. Therefore, the energy displayed on the screen does not imply a change in the mass of the disc itself.

Why the mass of disc does not changes according to Einstein's equation(e=mc^2) when we insert it inside a disc player and it shows us energy in the form of video on a tv/monitor screen.

  • I think there's something wrong in this question, can anybody point out the error with reasoning.

The disc does not change, therefore, its mass does not change.
Can you describe your reasoning in more, smaller steps?
 
Can you show the video without the TV and the disc reader being plugged in?

Thread 'Is there a white hole inside every black hole?'

This is what I am thinking. How much feasible is it? There is a white hole inside every black hole The white hole spits mass/energy out continuously The mass/energy that is spit out of a white hole drops back into it eventually. This is because of extreme space time curvature around the white hole Ironically this extreme space time curvature of the space around a white hole is caused by the huge mass/energy packed in the white hole Because of continuously spitting mass/energy which keeps...
