After Black holes, what are these White holes???

[thesolar65]

Basically what mean by parallel universe in layman's term is that there are infinite universes are out there. So may be white holes are the creator of new universes......may be!! As we type here new universes are created over there.

Some five year back my daughter who was a science student then pointed out to me as she was interested then. Alas she is going to be a lawyer after three years!!

Oh!
I guess I was the only galoot here.

So may be white holes are the creator of new universes......may be

Naaaahh!
White holes can't spit new stars out.

I don't think every thing in universe is dependant upon gravity to keep itself intact. In case of matter we can say that, but for dark energy......
May be White holes are not permanent. They born and die time to time.


How about if we say "gravity " is all about descend of Curvature in time space and this descend is created by matter object. Let's say there exist a similar ascend in time space which is created by anti matter or by some stuff which is opposite to matter..... does it create a "force" which is same in magnitude of gravity, but opposite in direction.....?

We always discuss curvature of time space in the form of "pit" which create gravity and his pit also bend light just as you said. How about we deal with "heap" or "cliff" of time space....?
This will generate an opposite response....

Please don't use the word "pull" and for heaven's sake, gravity ain't a force. It is just a curvature in space-time.

What if black hole is formed near this solar system?will it engulf them?



Astrophysics interest me alot and i get lot of criticism from my friends because i read about stars and the mars etc mission alot even during my exams

Depends on what was the mass of the star which formed a black hole. Suppose if our Sun tomorrow shrinks and becomes a blackhole, it will NOT effect the orbits of any of our planets except that the solar system would be extremely cold and dark.

Black Holes Vomit the things they suck , in the form of high intensity beam .

Does that mean Black Holes have a limit to what and how much they can suck in ?

Black Holes Suck even Light , So no way for Human eye to see it ?

Are Black Holes 2 dimensional tear in the Fabric of Cosmos or is it a 3 dimensional sphere ?

Do the massive explosion of a star , crushes the fabric within , leading to a path and hence another opening in Space ?

As per this Pic , Black Holes are 2D , with no depth ( or may be a 4th or 5th Dimension that we can't comprehend )

That there is a wrong picture of a black hole. The accredtion disk of a black hole somewhat looks like the one shown in the movie interstellar.

As for your dimension question, I honestly don't know. It's an interesting question though !

 

[Slav Defence]

You might not be but rest of Humanity is sure. All galaxies have black holes in its center and black holes have been confirmed to exist in universe through gravitational lensing.





They don't consume per se. That's a totally ignorant answer. By consume you are treating gravity as a force. Gravity as per "Theory of Relativity" is not a force but a curvature of space-time. So there is no sucking in.

Read on geodesics first. Light will travel a straight line because that's the smallest distance between two points on flat surface. However on curved geodesics the smallest distance may be a curve.

What the modern theory of gravity says is the curvature of space time around black holes are so twisted that light which follows a "SMALLEST DISTANCE RULE" on a geodesic has no possible way to come out. i.e. no such curves exist which comes out of the blackhole.

What it means is light is almost in an infinite loop inside a blackhole but it does exist. Just because it looks black doesn't mean it don't. It's just that things inside event horizon cannot be observed from any point in spacetime outside the horizon.
Black holes basically can be understood as all set of events in spacetime which cannot be located or ordered within our set of events in any way because of fucked up space time curvature
@Spectre @Kashmiri Pandit @applesauce @Slav Defence Your kind inputs please

Regarding white holes,I believe in them to some extent,well I wouldn't because there is no solid evidence of their existence.However, when we think about Einstein's statement regarding the concept of existence of mirror universe(He believed that mirror universe lies where white holes were present).I began to think of multiverse concept.
Quite confusing isn't it?
Let me elucidate,
Multiverse theory believes in existence of more than one universes,and recently an evidence is found that shows that our cosmic microwave glow has been increased-and this glow is sharper than before,which means that somewhere some other universe are there are might be they are coming closer.

Now what white hole has to do with it?Well,it is my just thinking that might be as Einstein talked about mirror universe which is what our white holes are leading,therefore..might be those white holes might be acting as gateways to other universes whose existence has been evident with CMB's sharper afterglow.
Well,that is my created correlation,might be these two are not related.
So,overall conclusion is that existence of white holes is not found,but that of multiverse is and might be these white holes(if existed) could act as gateways to those other universes which Einstein called his mirror universe.
So,correlate:

white hole----->mirror universe=other universe (discussed in multiverse theory,evident with sharper CMB afterglow)

Regarding blackholes,I have found some really interesting stuff and want to share,enjoy:

Tale of Two Black Holes

The real monster black hole is revealed in this new image from NASA's Nuclear Spectroscopic Telescope Array of colliding galaxies Arp 299. In the center panel, the NuSTAR high-energy X-ray data appear in various colors overlaid on a visible-light image from NASA's Hubble Space Telescope. The panel on the left shows the NuSTAR data alone, while the visible-light image is on the far right.

Before NuSTAR, astronomers knew that the each of the two galaxies in Arp 299 held a supermassive black hole at its heart, but they weren't sure if one or both were actively chomping on gas in a process called accretion. The new high-energy X-ray data reveal that the supermassive black hole in the galaxy on the right is indeed the hungry one, releasing energetic X-rays as it consumes gas.

In this image, X-rays with energies of 4 to 6 kiloelectron volts are red, energies of 6 to 12 kiloelectron volts are green, and 12 to 25 kiloelectron volts are blue.

Black Hole Has Major Flare

This diagram shows how a shifting feature, called a corona, can create a flare of X-rays around a black hole. The corona (feature represented in purplish colors) gathers inward (left), becoming brighter, before shooting away from the black hole (middle and right). Astronomers don't know why the coronas shift, but they have learned that this process leads to a brightening of X-ray light that can be observed by telescopes.



Normally, before a black hole's corona shifts, there is already an effect at work called relativistic boosting. As X-ray light from the corona reflects off the black hole's surrounding disk of material -- which is traveling near half the speed of light -- the X-ray light becomes brightened, as seen on the left side of the illustration. This boosting occurs on the side of the disk where the material is traveling toward us. The opposite effect, a dimming of the X-ray light, occurs on the other side of the disk moving away from us.



Another form of relativistic boosting happens when the corona shoots away from the black hole, and later collapses. Its X-ray light is also brightened, as the corona travels toward us leading to X-ray flares.



In 2014, NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, and Swift space telescopes witnessed an X-flare from the supermassive black hole in a distant galaxy called Markarian 335. The observations allowed astronomers to link a shifting corona to an X-ray flare for the first time.

It is funny when one starts to think of these abstract concepts, like universe set in a multiverse.
It all leads to new questions, where is the multiverse located, what kind of properties the space between universes' has and is there anything "above" it and what is the meaning of all this vast amounts of space, life in general.

Some new evidence has been suggested to support this theory.

I am negatively opinionated on the " every decision you make creates a new universe" theory, if only because of my vanity, as it would mean there's a me out there that made no mistakes making "it" more perfect. Blasphemy in short.

 

[Bilal saqib]

still we don't know whether black hole exist or not....

hats off sir what are you smoking nowadays?

 

[XenoEnsi-14]

White holes are the other end of black holes separated by time.

 

[Bilal saqib]

We are about 99% sure they exist now . But of course we are only scratching the surface literally of what they actually are.

in a theory they might be a tiny universe in it and it can lead to another tiny big bang whenever mass of black hole is enough it cant be handle by gravity same case in supernovas.. an other theory suggest that our universe BIG BANG might be a part of a single black hole big bang and there may be billions of universes due to other black holes called multiverse and that billions universe may be a part of big Universe.. Scientists called it unlimited universe. (Anant bharmand in hindi)

Bhai I have read on all this more than you can possibly imagine .

Carl Sagan is one of my all time heroes I miss him so much

On the contrary what it means is no option is PURE. All are same and have equal probability !

Equal probability means one of them has made all the correct choices where i haven't.

For example, New Year's eve celebrations 2000, i was flirting with some gal whole December at weekend parties, then finally managed to speak up and talk and when the time came to kiss, i literally fled from those lips that were away 20 cm max. To this day i do not know what happened, i just got some weird flash in my head, stood up and walked away.

If theory holds, there is some "me" out there that had an awesome New Year of 2000 (i had it too, could have been better if i hadn't have chickened out), that's reason enough to be mad (jealous/angry at myself and angry at "him" for being the better man is a better description) at him.

Ermm... no if there would just have been one ordered set of pure actions, then all other versions of you should not have existed

I think we have some sort of disagreement here or misunderstanding.

AFAIK, there's a theory out there that stipulates everytime someone decides on an action, a universe is created. I was talking about this theory. As per this theory, there is some "me" that chose all trhe correct options given to him in the constraints that my life provides (from here one set of actions comes)

Rather this would be the 5th and 6th dimension's information "tape recorder" in my opinion.

Action is a very lose word here, because the tape recorder would "log" the possibilities from even the quantum fluctuations at a subatomic level....and this would change things at a much more fundamental level than just actions (actions would be similar to the number of integers on the real number line....whereas the quantum random events would be like the number of irrational numbers....if you have ever come across multiple infinities stemming from the work of Georg Cantor).

In fact this quantum randomness may be what connects the multiverses theoretically...our most dominant well known "flavour" regarding them (as we perceive it) is string theory....but I think it will be a never ending quest for us as long as we exist. There may also be unbreakable information barriers in accessing these higher dimensions so the concept of exactly how these "other possible" universes might exist may never be known for sure.
