Discussion Overview

The discussion revolves around the concept of "warm holes," which appears to be a misunderstanding of "wormholes." Participants seek clarification on the nature of wormholes, their hypothetical properties, and their implications in physics, particularly in relation to space and time. The conversation includes technical explanations and analogies to help explain the concept.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • Some participants suggest that "warm hole" is a typographical error for "wormhole," which is described as a hypothetical region of space connecting two distant locations.
  • One participant uses an analogy involving a folded piece of paper to illustrate how a wormhole could allow for quicker travel between two points in space.
  • There is mention of wormholes potentially allowing for travel through time as well as space.
  • Another participant notes that constructing and maintaining a wormhole would require "exotic matter," which is not currently understood or available.
  • Concerns are raised about the stability of wormholes, particularly regarding their potential to collapse if used for time travel or communication into the past.
  • Participants provide links to external resources for further reading, emphasizing that a deeper understanding of wormholes requires knowledge of advanced physics concepts such as relativity and geometry.

Areas of Agreement / Disagreement

Participants generally agree that "warm hole" is a misnomer for "wormhole," but there is no consensus on the specifics of wormholes, including their properties and implications. Multiple competing views and uncertainties remain regarding their existence and functionality.

Contextual Notes

Participants acknowledge that wormholes are still hypothetical and consistent with existing theories, but none have been observed in nature. The discussion reflects a range of understanding and interpretations of the concept.

Who May Find This Useful

This discussion may be useful for individuals interested in theoretical physics, particularly those curious about concepts related to spacetime, wormholes, and the implications of advanced physics theories.

what is warm hole?

i read lots on warm hole but i am not getting anything about it...so please kindly explain me in very simple language...
 
Physics news on Phys.org


Do you mean "Worm Hole"?
I've never heard of a "Warm Hole"
I'll refrain from posting any "Your Mom" jokes about that...:smile:

I think you mean wormhole, as in a hypothetical region of space that connects two distant places.
 


Well, I'll be quietly shot in my sleep by hardcore physicists for this (of which I am one) but imagine a flat piece of paper. Imagine now on it two points A and B, which are at some distance from each other. Normally to travel from A to B, you'd walk from A to B on the paper.

Now imagine folding the piece of paper so that the points A and B overlap. Now we can go from A to B not along the paper but by 'jumping out of the paper and into it again'. Of course this way of travel is much quicker (though way messier because you'll be traveling out of the space you live in, which is the flat paper).

Such is the nature of a worm hole. A hypothetical 'hole' that connects two distant regions of space.
 


And time too.

Feeling the urge to post a few dirty jokes when I saw the title :P
 


sorry by mistake i wrote "warm" instead of "worm hole"...but still i am not getting it very clearly..please someone help in solving my this doubt...

Prhamitra, I am really considering your response to "What is warm hole?". Would you please give references in support of your viewpoint.

Basically if you could make a pair of wormholes you could walk into one and come out of the other. My post at #3 had a clickable link to a page that could help you (just click on the word wormhole).

A more thorough answer involves point out that wormholes require "exotic matter" to be built and maintained which we have no idea how to do (or even if it is possible). Then you run into the interesting stuff about wormholes collapsing if you try to use them to send messages back into their past light cone or perhaps not and allowing you to make a time machine.

http://www.daviddarling.info/encyclopedia/W/wormhole.html

and the first few lines of http://en.wikipedia.org/wiki/Wormhole

But do know that this is only an analogy meant for non-physicists and laymen. Actual understanding of these objects require knowledge of Relativity, Reimann geometry and singularities. Without going into any details what I said is more or less correct.

Also remember worm holes are still hypothetical in that they are consistent with existing theory, but is still to be found existing in nature.

A wormhole is like a tunnel that connects two points in spacetime. If the wormhole is "traversable" it acts as a shortcut through spacetime.
