Creating Black Holes?

The Schwarzschild metric admits negative square root as well as positive square root solutions for the geometry.

The complete Schwarzschild geometry consists of a black hole, a white hole, and two Universes connected at their horizons by a wormhole.

The negative square root solution inside the horizon represents a white hole. A white hole is a black hole running backward in time. Just as black holes swallow things irretrievably, so also do white holes spit them out. White holes cannot exist since they violate the second law of thermodynamics.

General Relativity is time symmetric. It does not know about the second law of thermodynamics, and it does not know about which way cause and effect go. But we do.

The negative square root solution outside the horizon represents another Universe. The wormhole joining the two separate Universes is known as the Einstein-Rosen bridge.

Yes, though this 'solution' is one of completeness, though not one of physical reality. An Einstein-Rosen Bridge cannot pass anything through it as its connecting 'wormhole' is infinitely narrow at its mid point in the model.
To open it, and allow passage of an object. A negative energy density must be generated around the object to widen the bridge. (Negative mass)

It requires there to be negative mass... which... thus far we have zero evidence for, and generating a normal mass field without actually... you know... piling things in one place, has thus far been impossible.

It falls into one of those curiosities of GR, which appears to be quite none physical.

a reply to: ErosA433

Today, Saoussen Mbarek and Manu Paranjape at the Université de Montréal in Canada say they’ve found a solution to Einstein’s theory of general relativity that allows negative mass without breaking any essential assumptions. Their approach means that negative mass can exist in our universe provided there is a reasonable mechanism for producing it, perhaps in pairs of positive and negative mass particles in the early universe.Their conclusion has far-reaching consequences.

They point out that if positive and negative matter particles exist in the universe, they would form a plasma that would have important implications for the future of astronomy.

Hey, hey.

Ok so check this out Nature is not necessarily something we completely understand. And if it were there would not be people claiming that we did, which by the way is bull#. There ain't no possible way anyone actually knows in reality what is up about the Universe!!!

Seriously this is ain't, nobody has any idea as to what the F@#$ is going on at such levels.

To further elaborate my position is that it is possible that what in general we define as infinitely is actually part of a gradient that is represented, in so far as we can comprehend, temporally.

Thoughts?

Very simple to create a black-hole phenomena in your reality. Proposed we live in a Planck environment and we are in 2-dimensional crystal form. Does the view we see in a vat brain or is it a real access place? Do we see and sense all the electrical impulses given to the brain including touch? Very difficult to answer as we do not truly know if we are really experiencing reality of a dream or a sort.
Yes we can create a black-hole as it is only in our mind to do in either form of observance. We are the creator of our own reality due to we are our own creature of existence.

There are other realities?

Proposed we live in a Planck environment

Which is?

and we are in 2-dimensional crystal form.

I think you mean a flat, tightly packed molecular arrangement. Chemical bonds require at least 3 dimensions and atoms have thickness.

Does the view we see in a vat brain or is it a real access place? Do we see and sense all the electrical impulses given to the brain including touch? Very difficult to answer as we do not truly know if we are really experiencing reality of a dream or a sort.

So, let me get this straight, the reality in which we live is not real, but there are lots of realities floating around?

Yes we can create a black-hole as it is only in our mind to do in either form of observance. We are the creator of our own reality due to we are our own creature of existence.

It is far easier to dig a hole, then paint it with black paint.

In Inflation theory with respect to Big Bang theory, we consider that space-time expanded at FTL and so moving the matter that way at such speeds.

Black holes as offered are openings in space-time so is the implication of a while hole the effect of some force that directs such energy back into what we call the Universe?

The idea of white holes seems unlikely. Not just because of the topology of space-time like like Chron. mentioned but also because it would mean black holes would expel their mass, probably very quickly out of the white hole.
Once it lost enough mass it would stop being a black hole. We don't see any evidence of black holes doing that.

CAN'T they mess with mass anyway in the black
,USE that.

a reply to: joelr

A way to understand how a while is possible is similar to the idea that everything that goes up must come down. In other words, a black hole tries to eject energy out of what we commonly relate to as the Universe and that energy gets sent right back because it cannot escape the object from which is resulted from and so returns. So there is no way that such mass can achieve escape velocity in relation to nature.

In so far as what we "see", the math in relation to theoretical physics presents that just as with black holes. Wherein we did not in the past have the means to identify them. Given we have found that over time. The works that offered their existence, will result in our identifying the rest which in this case would include white holes.

I mean seriously we identify black holes, determine EPR paradox to the extent of quantum teleportation but ER Bridge is what, impossible?

Consider this thread and exercise the how would one make a Black Hole?

actually it is indeed very easy, take a piece of paper and do this....


if you change the numbers, you can also create a MASSIVE BLACK HOLE, or if you like even a tiny MICRO BLACK HOLE

all depends on the numbers you put into the equation

have fun creating Black Holes !

a reply to: KrzYma

If you look it up you will find that during a voyage at near the speed of light once the craft has moved away from our solar system, the speed will increase due to the lack of mass in the region. The measurements we take of the speed of light are from our current position which is Earth. Even the Voyager series while not actually will accelerate because of this factor or for that matter any other object for that matter.


If one cannot achieve escape velocity from a black hole its because its escape velocity is faster than that of light. The gravitational field that a black hole generates is superliminal and so operating in some way faster than light.

The issue of entropy is such a situation offers theoretically that despite a black hole is functional at superliminal speeds and experiencing Hawkins Radiation is that despite the fact that it operates at FTL, it is having a finite experience.

Thanks, I let you know how it all works out.

Thoughts?

By using the twin polar jets emanating at near the speed of light...from the accretion disc of a spinning micro-mini black hole, they could be a propulsion source onboard a starship; with it being capable of achieving superluminal speeds, as long as the micro-mini BH propulsion unit onboard the starship is being fed starlight photons or plasma for constant acceleration --- With the starship mimicking zero-rest mass by being equipped with off-board magnetic shields, generated by the micro-mini black hole itself.

a reply to: Erno86

There is a postulate that presents that electrons. protons and neutrons are another versions, of black holes. The idea being that information can be compressed to an extent that it represents as something solid. Personally, I find the idea, intriguing, in the sense that during the early universe the energy released could have resulted in implosions beyond just 4D.

Given that spacetime curvature is the result of mass and the Universe as we understand it is a construct, then potential energy in function to mass, allows for that curvature.

Sub-atomic particles then are representative of such, a phenomenon.

Thoughts?

Its to suggest that what we call a stellar black hole or a supermassive black hole is an event that simply is consistent, with nature as a result of how reality as we understand it originated.

GENERAL relativity and quantum theory have profoundly changed our view of the world. Furthermore, both theories have been verified to extraordinary accuracy in the last several decades. Loop quantum gravity takes this novel view of the world seriously, by incorporating the notions of space and time from general relativity directly into quantum field theory. The theory that results is radically different from conventional quantum field theory. Not only does it provide a precise mathematical picture of quantum space and time, but it also offers a solution to long-standing problems such as the thermodynamics of black holes and the physics of the Big Bang.

A point would be that Stellar Black Holes, as well as Supermassive ones, are interacting weakly with the strong force.

Consider this thread and exercise the how would one make a Black Hole?

Well I suppose if we took this whole planet with all these things on it, in fact the whole neighboring planets as well, oh and the sun as well. Or never mind not enough mass and energy required in this crummy 9 to 12 planet system.

What a bummer. But! Maybe if we took in the next few neighboring suns as well. And then somehow squished and compressed them and the whole thing down to the size of an apple. Well then just maybe, we would have the energy required, to just maybe make a black hole.

It would be like presto, magic, with a dash of salt, and you have yourself a black hole.

That! Or we can try bouncing a graviton particle beam off some sort of main deflector dish, who knows, maybe that will work.

a reply to: galadofwarthethird

Black holes generate radiation as a result of their processes and essentially responding like a solid object but due to the extent of the radiation, they do seem to be interacting weakly with some fundamental force.

Clearly and with all due respect the residual strong force and or nucleon-nucleon, force, is exactly what is being broken down.
