I want White Holes ...

WEll i would imagine if White holes ever exited the realm of theoretical they will be put in the game
Too much supposition on their existence, whilst there are (or were, been a while since I checked) solutions to General Relativity that would lead to White Holes, there's really no evidence of their existence.
There's something about them that feels as though we're cheating the second law of thermodynamics as well to me... The way around that is they're supposed to be balanced by black holes, but since black holes are now alluded to be not cheating as much as we thought (maybe) it makes the existence of their counterparts less likely.

No, just a cup of tea, thank you.
This. Entropy is a thing. White holes, ergo, can not be. I like Red Dwarf as much as the next smee- hee--, but in ELITE it'd just be too implausible.
Black Holes Matter

...only joking!
In universe time, short lived could be a million years ...
Just had a look (thread piqued my interest) and yeah, pretty much as I thought, 'white holes' in the classical sense are pretty much out of the picture, unless we actually find them.
Current theories:
Black holes and white holes are the same thing - Black holes with variations of temperature variation
White holes create new universe and our own big bang was a white hole event
Some classes of gamma ray bursts are identified with very short lived (seconds) white hole events.
None of which really lend to classical white holes being in the game.
PS. I cheated and checked wikipedia, didn't have the time to do some quick solutions of GR.
PPS. The universe throws up some strange and wonderful things, I don't think anyone can ever rule out something like this until we have much better data. Considering what we HAVE worked out given the feeble amount of information we've picked up from the universe around us is absolutely amazing. That said, I stand by my earlier statement, it looks unlikely white holes like the OP's image exist.

It's not quite that simple, in fact white holes were a nice solution to black hole entropy. Because of the exotic nature of black hole material, so exotic we don't know what it is and could be anything from a mass of swirling exotic energy to 5 trillion Physical Education Teachers it's basically 'hiding' information from the universe.
There's the famous 'If I let a cup of tea cool down, I can hide my entropy crime by throwing it into a black hole' example that was either Hawking or Gribbin, I can't remember. WHITE holes originally provides a nice solution to this. You throw in a cup of cooled down tea into a black hole, a white hole throw it back out into the universe, showing the universe your crime again.
What I mean by the current solutions, there's hints that black holes aren't quite hiding their information as well as we originally thought, so there's no need for a white hole balance.

Lots of suppositions, lets remember that the Big Bang, General Relativity, hell even the Rutherford atomic model are theories.
Theories last until a better one replaces them. And this is also true of the nursery school physics that are Newtons laws, you guys know that Newtons laws are limited to the 2 dimensional, right? Thats the reason we needed Rocket Science, you introduce Spin and Newtons Laws are pointless.
Currently a fan of Projection theory, you dont really need white holes for that. Plus if our Universe is a leak frrom a dense vacuum (aether, prana, zero point, dark matter pick your buzzword) then you have an answer to a lot of issues.

Hmm... Newton's laws are fantastic and not limited to 2-dimensions. They still today work at the every day level. Special and general relativity only come into play once we start getting to decent speeds of a decent fraction of the speed of light or over long long periods of time. ROCKET SCIENCE mainly used newton...
PS I'm an English teacher now, but I was trained as an astrophysicist.
PPS The 'big theories' didn't replace each other as in: the old theory was proved wrong, but actually incorporated the old one. Special relativity equations when solved for low speeds are equivalent to newtons equations. General relativiy equations when solved for zero accelerations give special relativity. It isn't quite the 'well the old one was wrong' that some people think. The old one was right (and still is) but we now know under other conditions we needed to modify, not replace the old theory.

yes true, but if a white hole lasted for that long we would defiantly know about them by now.
in theory they spew out an incredible amount of energy and are much more powerful than a supernova, and supernovas we detect all the time in far away galaxies.
i admit that i am a bit doubtful that they exist, but i am not going to ride them off as impossible until someone explains the odd gamma ray bursts that we have seen or the big bang event.
There's still space for them in some ways, but not in the classical sense. From what we understand.
I will say they were in my area of expertise because back in the day I was a time travel (using physics) nut. Singularities featured heavily in pretty much all of the more plausible methods of time travel.
