Can a Black hole also be a wormhole ?? is it possible
Sangam Swadik said:Can a Black hole also be a wormhole ?? is it possible
Researchers have no observational evidence for wormholes, but the equations of the theory of general relativity have valid solutions that contain wormholes. The first type of wormhole solution discovered was the Schwarzschild wormhole, which would be present in the Schwarzschild metric describing an eternal black hole, but it was found that it would collapse too quickly for anything to cross from one end to the other. Wormholes that could be crossed in both directions, known as traversable wormholes, would only be possible if exotic matter with negative energy density could be used to stabilize them.
Would such a theoretical wormhole be possible with just one black hole, or would two black holes be required (one at either end) with "exotic (nonexistent) types of matter with negative energy to keep the wormhole open?" In other words, would the entrance of a theoretical wormhole have a similar mass and density as a black hole? If so, would that not pose a problem for anything attempting to leave a theoretical wormhole?Drakkith said:It is possible only in the sense that there are valid solutions to the equations of General Relativity that give us a wormhole. It is extremely unlikely that wormholes are physically possible due to the need for exotic (nonexistent) types of matter with negative energy to keep the wormhole open.
From here: https://en.wikipedia.org/wiki/Wormhole
Note that matter with negative energy density does not exist as far as we know.

Sense said:I'd say the black hole itself is the exit, as everything entering it is concentrated to a single spot. Maybe because everything "shrinks" there is a miniature universe in this one single spot in the centre of the black hole. You could never get out because inside this universe, the other side of the black hole would look like the big bang as it creates this miniature universe from everything it pulls in on the positive side and creates on the miniature negative side from a single spot. Thus also explaining the big bang. Inside this new universe again black holes appear and repeat the same progress over and over again. Creating universe after universe recycling itself for ever. So maybe at the centre of our owne universe, there is a single negative black hole(white hole?) spewing out new pieces for our universe and this is also why we keep expanding. And we can locate our centre by finding the blastwave of our big bang and use that to calculate the centre.
If a theoretical wormhole were connected between two black holes, one at either end, there would not be a "white" hole since nothing could ever leave the gravitational effects of a black hole. To paraphrase the old "Roach Motel" commercial, mass can check in, but it can't check out. One, or both, of the black holes that form the theoretical wormhole would just get more massive as mass passes the event horizon.Loren said:Well, one problem would be mass. If a black hole acted as a wormhole it would be depositing mass somewhere else besides inside the black hole, which means that the rate of increase of a black hole would either stop or decrease in spite of it continuing to ingest more mass.
The second problem is that no where have we observed mass or energy simply spewing out like a fire hydrant in the universe (i.e., a white hole).
Loren said:There is no center of the universe and no one point where the Big Bang happened.
The Big Bang happened everywhere in the universe at the same time.
I blame our educational system for perpetuating this myth along with all the science shows and magazines.
Sense said:You did not read my opinion rigth, because if we ourselves started out in this way, it would be described as everywhere because it is at the same time the creation of everyting that is. So indeed that woud "feel" like everywhere. But that is in a 3 dimensional way of thinking. My opinion was more than that if you would be able to understand what i tried to make clear.
Loren said:I am interested in understanding your point, but I need help. Can you better clarify it for me?
Sense said:Well to start off, i am just trying to make sense of everything so i could be wrong or right, i know that. But i like to think that i know alot.
If i am wrong I'm hoping very much for the right info to correct, and maybe answer this big question.
If everything ending up in the black hole gets concentrated to one single point perfectly gettng squeezed together. This might be in the exact form of what it sucked in, only in a miniature way. Of course this is a very violent progress and it would be very difficult or impossible to do this and come "in" alive.
Now imagine being in the black hole the moment is is created (imploding star)
First the star implodes to a single point, then immediatly it starts being a black hole. For the first time since the creation of this single point it now starts sucking in materials and energy. Inside this black hole at that exact moment i imagine it being very compareable to our big bang.
Because from within this black hole/new universe it would seem like new material coming "in" first is a destructive explosion because it sucks in the remains of the star/energy in. now it starts sucking in the surroundings and it gets calmer. Just like after our big bang. Maybe the material inside the black hole again creates a mini universe.
We don't get material but keep expanding because our "white hole" is on its other side sucking in nothingness or black energy. Thus explaining our expanding.
Thats maybe also the reason it comes in everywhere, because a white hole has not be found, it could be 4 dimensional, thus energizing our whole universe with black matter instead of from a single point.
newjerseyrunner said:Black holes are not perfect points, because of the intense warping of space and time, it would actually take an infinite amount of time for everything that fell into it to be crushed to a point.
Loren said:An interesting point.
It's true for the outside observer, but not on the local frame of the inrushing matter.
This is a common misconception. You would cross the event horizon as if it wasn't there; infinite blueshifting/time dilation happens at the singularity, not at the event horizon. You'd still be able to see the universe (albeit compressed to a very small disk) progressing with relative normalcy until well after the singularity stretched you into spaghetti.serp777 said:In theory you would see the universe speeding up if you were falling into a black hole since for your frame of reference the universe would appear to experience time more quickly. Its possible you would see the entire duration of the universe pass before your eyes, and it would becoming increasingly faster the closer you got to the black hole. The universe might actually end and the black hole could be destroyed by hawking radiation before you were killed by the gravity of the black hole itself--im talking about supermassive black holes.
What I was trying to say, but failed miserably to say.Chronos said:As you, the observe,r streak toward the singularity Light entering from outside the event horizon struggles to reach you [you being further inside the EH] thus it appears to be redshifted. An infalling observer does not see the entire future of the universe in a blue flash of glory during his altogether brief journey from the event horizon to the singularity. The only way you could observe this [i.e.infinite blueshift would be to hover in place at or inside the EH, which is impossible.
This is a common question among those interested in theoretical physics. The short answer is that while black holes and wormholes share some similar properties, they are not the same thing. A black hole is a region of space where the gravitational pull is so strong that nothing, including light, can escape. On the other hand, a wormhole is a hypothetical tunnel that connects two distant points in space-time. So, while a black hole can theoretically lead to a wormhole, they are distinct objects with different properties.
As mentioned before, a black hole is a region of space that has an incredibly strong gravitational pull, while a wormhole is a hypothetical tunnel connecting two distant points. Additionally, black holes are formed by the collapse of a star, while wormholes are purely theoretical and have not been observed in nature.
Some scientists have theorized that a wormhole could potentially form within a black hole, acting as a sort of "back door" that allows matter to escape the singularity. However, this is still just a theory and has not been observed or proven.
While the idea of traveling through a wormhole may seem like something out of science fiction, the truth is that we do not currently have the technology or understanding to make this a reality. Even if a wormhole did exist, the intense gravitational forces and unknown properties of such a space-time tunnel would make it incredibly dangerous for humans to attempt to travel through.
One of the most fascinating aspects of wormholes is the possibility that they could lead to other universes or parallel dimensions. However, this is purely speculative and not supported by any scientific evidence. The existence of other universes is still a topic of debate in the scientific community, and there is currently no way to prove or disprove the idea of a wormhole connecting to another universe.
