Black Holes & White Holes??

[demonsight]

My friend wants to know, where to black holes lead to. He rekons they lead to a white hole. where do they lead??

 

[harmonicaman]

<i>...where do black holes lead to?</i><br /><br />Black Holes are very dense accumulations of mass. Mass is a static entity in the universe, it can neither be created nor destroyed^(1.) Time and mass are incompatible together because time is constantly flowing -- it cannot co-exist in the same area of space (on the quantum level) as the static mass. <br /><br />In a Black Hole, the mass is so compacted (even the atoms are crushed) that time must infinitely curve around this area of space. A black hole has no time available to do anything or go anywhere; it just sits there and watches time go bye...<br /><br />And futhermore, no candidate White Holes have been observed which would be the theorized places where Black Holes would emit their flux...<br /><br /><b>1.</b> Law of Conservation of Mass<br /><br />

If you penetrate through one side of black hole and come out through other end ,you reach white hole.

That sounds more like science fiction that science.<br />Can you provide any links that show this theory?<br />Reputable scince links only, please? <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

While theoretically possible, Alok, there has never been a single shred of evidence for the existance of White Holes. And, I might add, it is only one of a range of theoretical possibilities (up to and including that Singularities "reattach," but far away in our universe, or even some other universe entirely!).<br /><br />And sure, if they existed, and you could pass through them, it would be very interesting. But as we understand the theoretical basis for Singularities and White Holes, you would exit as a stream on incoherent radiation, not as "you." <div class="Discussion_UserSignature"> <p><em>Differential Diagnosis:  </em>"<strong><em>I am both amused and annoyed that you think I should be less stubborn than you are</em></strong>."<br /> </p> </div>

[alokmohan]

Then no point going there.

True. Getting torn ("Spaghettified") to your constituents sounds less than desirable. <div class="Discussion_UserSignature"> <p><em>Differential Diagnosis:  </em>"<strong><em>I am both amused and annoyed that you think I should be less stubborn than you are</em></strong>."<br /> </p> </div>

I promise not TO GO TO WHITE HOLE.

[alokmohan]

I do ,tell me why not?

 

[harmonicaman]

While it's true that you can mathematically model a Worm Hole and its associated White Hole, this is just a paper theory. These objects have not yet been observed to actually exist in nature.<br /><br />IMO; the mathematics describing what is really occurring beyond the event horizon of a Black Hole is still an unknown -- and this is admitted by most cosmologists. <br /><br />The Worm Hole theory sounds plausible on paper, but observation seems to show it probably isn't correct.<br /><br />I think Black Holes just sit there, very cold and quiet -- they have arrived early to the end of the universe! <br /><br />BTW; anybody at all may submit anything they want to Wikipedia, it is not peer reviewed or associated with any scholarly organization. Some entries are spurious!

 

[MeteorWayne]

Because wikpedia entries are written by anyone. Some know what they are talking about. Some do not. Some are kooks. The idea of Wikpedia is that over time the truth will float to the surface, but on some wacko topics, reputable people won't even take the time to write a correction.<br />You cannot assume that everything you read there is correct, you can use it as a starting point but need to do some more research on your own, especially on controversial topics.<br />That's my opinion anyway.<br /><br />Wayne <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

[harmonicaman]

The same can be said for SDC...

Absolutely true, harmonicaman!<br />I've only been around for a few weeks, but I'm getting a feel for who has their head screwed on straight, and who's screws are loose <img src="/images/icons/laugh.gif" /> <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

[why06]

if you go past the event horizon of a black-hole you will be in a white hole.....its thats simple <img src="/images/icons/rolleyes.gif" /> <div class="Discussion_UserSignature"> <div>________________________________________ <br /></div><div><ul><li><font color="#008000"><em>your move...</em></font></li></ul></div> </div>

Dear Harmonicama, i Had notion that it is present day Encyclopedia Brittanica.Please help out.

Who says so? <br /><br />And Why?<br />And Why?<br />And Why?<br />And Why?<br />And Why?<br />And Why? <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

[alokmohan]

Astronomers of various views.Some of them think that yougo to white whole if you manage to pierce your way in.But due to tidal action you become torn.You dont reach there intact.

 

[MeteorWayne]

In current theory I don't think there's much support for the BH -> WH path, but that is theory well endowed with unknowns.<br />MW <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

[derekmcd]

I think the idea of White Holes has arisen from our fundamental lack of understanding of the idea of "infinite". A singularity is infinitely small and infinitely dense... and matter keeps "falling" in... it has to go somewhere. Well, if you can't grasp the concept of infinite, the alternate conclusion is that the infalling matter has a final destination other than the singularity... hence a white hole somewhere else. <div class="Discussion_UserSignature"> <div> </div><br /><div><span style="color:#0000ff" class="Apple-style-span">"If something's hard to do, then it's not worth doing." - Homer Simpson</span></div> </div>

 

[MeteorWayne]

Well put, derekmcd. I wish I'd found those words. <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John. Monsters.

[weeter]

could the matter within a singularity be moving backwords in time and emerge at the big bang?

 

[lroux]

There is no scientific reason for white holes to exist. In fact, one can most assuredly count them out.<br /><br />1. any entity that was a white hole (ie the "outflow from Black holes" would have as much mass at its center as the black hole and would, by virtue of physics, BE a black hole.<br /><br />2. Matter falling into a black hole experiences time dilation. In a sense, it would take forever to reach the center of a black hole and that negates matter "falling through" it.<br /><br />3. There is no observational evidence of a white hole at this time. If black holes are observable, one would think that matter shooting into our universe from seemingly nowhere would be far more detectable. <br /><br />ergo...no white holes.

 

[enigma10]

You need to follow the Einstein-Rosen bridge. White holes, being another name for worm holes are often discussed, but mostly dismissed due to direct evidence of thier existence. <br /> I would suggest you pay close attention to the hypothesized nature of a singularity and it possible relation to black holes. You'll find a common attribute of the laws of physics not existing as we know it. This, of course, would weaken the argument that the 2nd law of thermadynamics prevents the possbility of a white hole.<br /><br /> Either way. Black holes and white holes once shared the same place in science, before one was found, so anything is still possible. <div class="Discussion_UserSignature"> <em>"<font color="#333399">An organism at war with itself is a doomed organism." - Carl Sagan</font></em> </div>
