Einstein-Rosen Bridge

[Dryson]

A very good read about black holes and Einstein-Rosen Bridges.

https://www.ias.edu/articles/einstein-rosen-bridge

In a game I play there is a shield around a base that looks like an Einstein - Rosen Bridge.

The top image is of the field looking at it from the side. The bottom image is looking at it from an off angle. If you look close enough the swirling effect creates an S. Would it be possible to somehow side jump from the bridge it self and arrive at the other end of the bridge a lot faster than if simply traveling through the center? Basically would be down the S curve of the bridge instead of a straight line.

I think Tyson Degauss or Michio Kaku might be able to answer this question given their knowledge of the subject.

To tunnel through a S-T manifold, you need to create another wormhole (which is what an E-R bridge is). Creating a stable wormhole requires generating a negative energy density. If we knew the nature of dark energy and could control it, perhaps it might be possible to create stable macroscopic wormholes.

Could you cause the top and bottoms of the E-R bridge to come closer reducing the distance between the top and bottom openings by folding the first wormhole basically in half?

I will call them horns like the instrument. If the top horn is bent counter clockwise to the 9 0'clock position and the lower horn is bent clockwise to the 9 o'clock the opening and exit would exist at the same moment in space-time.

Maybe this is one way that time travel would be possible or one way that you would not suffer time dilation from traveling through the length of the wormhole. It would be like stepping through a door from a winter wonder land into a nice summer day and being able to feel the weather from both seasons at the exact same moment.

KIRK! Why are you in my wormhole?

[Dryson]

If you think of a wormhole as a corridor with two open doors at either end there is an amount of time spent traveling between the two doors.

If you bring the two doors closer you have effectively cancelled out time dilation between the two areas of space that you enter and exit into and out of.

 

[Robert Maxwell]

If the sets of doors occupy the same point in space, what's the point of a wormhole?

Same thing I was wondering.

Maybe he is talking about the actual length of the corridor between the two holes.

A wormhole is a connection through the "bulk" (the higher-dimensional space) to connect two areas of our regular space (the brane). The corridor inside the bulk can be either long or short.

I remember reading in one of Kip Thorne's books about how a large source of gravity near one of the wormhole exits combined with a short or long bulk corridor between the holes could affect the ability to actually time travel. I'll have to look that up.

 

[RoJoHen]

But I feel like his point is "It takes less time to travel a short distance than it does to travel a long distance," in which case...duh.

I was reading about the Highs at CERN site and was wondering if a reverse process would be necessary to reduce particle mass within the wormhole itself.

 

[Asbo Zaprudder]

If you reduce the inertial mass of your constituent particles too much, you disintegrate. I assume that the Higgs field does exist within a wormhole but if the vacuum expectation value is different, it might be dangerous to venture within.

According to CERN the particles passing through the Higgs field exist prior to the interact with the Higgs field. Without the Higgs the internal mass of the particles does not exist as the Higgs is the particle that adds mass to the elementary particle called quarks and leptons.

If inertial mass is reduced we wouldn't disintegrate we would exist within another dimension of space-time that the quarks and leptons occupy. If the vehicle we were in that was passing through the worm hole emitted a field around it that was directed outwards and reduced the amount of particle mass by reducing the particles to quarks and leptons because of the sudden force being exerted on the field that the internal mass of the occupants would still exist based on the transfer of energy placed upon the field itself.

I can see the process that I am thinking about in my mind but it is hard to explain.

Maybe it be best explained by how a black hole functions. We know that when a star collapses the immense pressure from the layers of the core above the sun fall inwards occupying the space vacated by the core itself as it consumes its last amount of fuel. In this case however we are removing gravity from space as well by removing the mass from the particles within an area around the vehicle. Gravity like the layers the sun would possibly try and occupy the space left behind. The field would continue to reduce the particles of mass while gravity tried to occupy the now vacant space. There would still be a force exerted on the vehicle within though because of the immense amount of gravity trying to occupy the recently vacant space.

I will have to check with CERN and NASA to see how well this idea holds up though.

 

[Dryson]

In order to create an artificial wormhole wouldn't we have to be able to control gravity?

If space time is bent in half on a micro scale couldn't we occupy a distance across space time at a much faster rate?

By bending space time I mean bending gravity somehow the same as light is bent by gravity. If we can bend gravity and still pass through the void without disentigrating would be able to move faster then the speed of light across smaller distances and not be affected?

 

[Asbo Zaprudder]

I think you're describing the Alcubierre Drive. Again, you need a source of negative energy density. This link includes a reference that suggests that anyone inside a superluminal warp bubble wouldn't survive.

 

[Dryson]

Another idea would be to put the field at the forward edge of the vehicle that would create a half of sphere. When the field is powered on it would create empty space in front of the object. The gravity would push the ship into the space without gravity along with the field reducing the gravitational pull on the vehicle from behind as portions of the gravitational field would be reduced in mass.

This is of course if an anti higgs boson exists.

Such a particle would have to exist that would neutralize the highs ability to create mass. Otherwise when the Big Bang occurred the expanding energy would have simply continued to accelerate faster than light where our universe would be a lot larger than it is

Could a negative energy density be the space on the outside of our Universe?

 

[Asbo Zaprudder]

By definition of it being all that there is, the Universe has no outside.

ETA: The observable Universe, and some portion beyond of unknowable extent, might be a condensation within an eternal inflaton field as there is no way of halting inflation once begun. There is also the theoretical possibility of parallel branes so the real Universe might be even more unknowingly large and complex.

 

[USS Triumphant]

Could a negative energy density be the space on the outside of our Universe?

Total amateur on this subject here, but could a negative energy density on the outside of what we think of as our universe that is effectively pulling "stuff" outward be an alternate explanation to the dark matter that the equations imply must be there for universal expansion to be proceeding at the rate that it is - but that they can't seem to find?

If any part of what I just said seems to require elementary education to correct a misconception on my part, then just kindly disregard. Unless you really feel like teaching a beginner's class on the subject.

 

[Asbo Zaprudder]

The current observation that the expansion of the Universe is accelerating is often attributed to dark energy that has a positive density but which exerts a negative pressure. Dark matter is invoked to explain anomalies in the rotation of galaxies and other gravitational effects. We don't know the nature of either dark energy or dark matter. There are other unsolved problems such as why the Cosmological Constant (usually equated to the energy density of the quantum vacuum) is 120 orders of magnitude smaller than quantum field theory predicts. This is famously known as "The worst theoretical prediction in the history of Physics".

A wormhole is a connection through the "bulk" (the higher-dimensional space) to connect two areas of our regular space (the brane). The corridor inside the bulk can be either long or short.

What's to keep the wormhole from being longer (in the "bulk") than the distance between its ends in "normal" space? You may travel through a wormhole only to find that you've traveled farther than you would have normally.
