Homework Help Overview

The discussion revolves around the concept of naked singularities in the context of Einstein's solutions to gravitational collapse and their implications for future predictability in spacetime. The original poster expresses confusion regarding the nature of future predictability and the potential violation of physical laws if naked singularities exist.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants explore the implications of naked singularities on predictability, questioning what is meant by future predictability and how it relates to the age of collapsing stars. There are inquiries about the reasons behind the conjecture that physics may lose its predictive power in the presence of naked singularities.

Discussion Status

The discussion is ongoing, with participants raising questions and seeking clarification on the nature of future predictability related to naked singularities. Some guidance has been offered regarding the influence of singularities on future events, but there is no explicit consensus on the implications or definitions being discussed.

Contextual Notes

There are indications of confusion regarding the definitions and implications of naked singularities, as well as the assumptions underlying the conjectures about predictability in physics. The original poster expresses a feeling of being overwhelmed by the complexity of the topic.

Homework Statement




i have a problem about the naked singularities which are appeared in einstine' s solution and mathematically possible ... in that i have readed that for the weak conjecture states (by the penrose and hawking singularity theorems ) that all singularities in gravitational collapse are hidden within black holes.This conjecture implies that FUTURE PREDICTIBILTY of space time outside the event horizon.The Strong conjecture asserts that no singularity visible to any observer can exist.

Homework Equations


my question is that what kind of future predictibility is meant here and why it is violating the laws of physics?and i have readed that physics will loose its prediction power...If naked sigularity exist?please help me in finding out solution of such a question which is completely beyond my thinking power.

if we found you a question above your thinking power. what use will it be to you ...if you won't understand it (as you say u want a queiton above your thinking power)?

Sorry ! there was mistake in my post.Now Help me to find out the solution of it Plz if you can
 
The idea is that when a singularity is hidden behind an event horizon, such as is the case in the Schwarzschild solution, it cannot possibly influence anything that happens in the future of a region outside the event horizon.

However in cases where the gravitational collapse is non-spherical it is not proven but only conjectured that the singularity is still hidden. If it is not hidden then there is no future asymptotically predictable region.
 
yes ! but i want to know what kind of future prediction is meant here?either of the age of the collapsing star or what?
Also if we can see from the distance in the naked singularities why it is suggested that the physics will loose its prediction power?i know when it is suggested but what is the basic reason to conjecture about it?

We can't perdict what will come out of a naked singularity, maybe atomic bombs, electromagnetic energy, 17 million clones of Britney Spears, etc.

Such things can wreck havoc with any event in the future of the naked singularity.
 
THANKS FOR HELP
