Where we currently stand in Physics with Symmetry, Wormholes, Space-Time and Gravity PT.I

Time as you understand it is a function of symmetry. Symmetry is a fundamental principal of the observable universe. True symmetry cannot exist at the "local" level. You must be able to reference all non-local frames to find it. You can model imperfect symmetry mathematically by saying 0.9999... is in fact equal to 1. It's also the reason why the square root of -1 is an "imaginary number". That is not to say that true symmetry is not a concept unlike infinity, in that it most certainly should be able to exist. Science is just now learning the principals of "symmetry breaking".

It will take another few thousand years to get the math right, but we will eventually find a pragmatic way of manipulating "vacuum barriers" of local frames using exotic matter. Even with atomic clocks, it will be difficult to measure the quanta of time in precise units. It is best, therefore, to measure time in terms of alignment of "frames". Frames to you would be what will eventually coined as "vacuum barriers". This is the home of the virtual particle and the progenitor of the Casimir effect. We can precisely measure frames in units of degree. We use the light from distant stars to do so. We have an aperture that allows us to use simple Pythagorean math to triangulate the difference between "local" and "field" frames. Just to note that the science for this actually came from optical research. Infact to relate to popular culture, there is a game franchise called "Portal" which used this term, which is what makes this localized frame so interesting.


There were several other games such as "Deus Ex" which share the same attractor to this reference. We use the term "attractors" to mean those events which we can record with a certain degree of accuracy. That is, to move "backward" in time means that you also abide by the notions of Heisenberg (The same Heisenberg who coined the Heisenberg “Uncertainty Principle”) In essence, you alter the "past" just as you would trivially by existing in your own local frame. Attractors can be heralded by things that people  find interesting and record. The marching’s of Hitler and his Third Riech. The Mayans and their production of calendars. The Revolutionary War that spawned America. And so forth. These charter events almost always have an attractor associated with them. It is like a heavy ball of lead on a sheet: The attractor warps localized frames in such a way that makes them more congruous to your conventional visualization of space-time. What you need to exploit the breakage of symmetry as it relates to "time" is to inject exotic matter into localized frames.

Exotic matter has a tendency to have negative density. As mentioned in a previous article (Warp Drive:The Theory). We suspect that lattices of high-energy gamma ray lasers were used to create the first observable particles of exotic matter. Currently the Hadron Collider is not powerful enough, and it would take a few dozen suns exploding to break the coulomb barrier needed for a nucleonic force. The quanta of high energy gamma rays, then, can be used to step-up mass ejection of virtual particles that then decay into exotic matter. Due to their incredibly short lifespan, we have not been successfully able to build a transversable wormhole through ordinary space-time that would allow teleportation-like phenomena on the macroscopic scale. However, wormhole theory does describe how local frames are exploited. Kip Thorne thought experiment using a gravity well is still valid. We just can't prove it topographically. But the effect of local frame manipulation mirrors this almost precisely.

Einstein’s Theory put to the test

Just recently a star that is orbiting around a Black Hole is moving at an incredible speed. A speed that is rarely seen, given the conditions. A particle star is orbiting around our central Galactic Black Hole that sits in the middle of our galaxy, known as the Sgr A*, A super Massive Black Hole. An intense Black Hole with the mass of 4 million suns with the equivalent mass of 1 of those Suns equal to our own. This star that was newly discovered, which is known as the S0-102 would be able to give an opportunity to allow the Einsteinian Theory of Relativity to be put to the test.


With the theory, it is predicted that the mass of an object is able to distort time and space. Known only as space-time, a fabric that is ever present in the universe and that these objects with high mass and density are able to distort and slow time down, also can even stretch and shrink the distances in the space-time continuum. The Super Massive Black Hole that is in the centre of our galaxy (Sgr A*) has really high mass, and is the lynch pin of our galaxy and allows out galaxy to work properly. There are reports and data to show that there are stars a couple of light years away from our galaxy centre in our galaxies centre, though the centre of the galaxy known as the most violent and extreme 
environment in our galaxy currently, leading with its high level of starts making the zone very dense.
Stars that would be close to the Super Massive Black Hole are actually traveling around 4,000 Kps (Kilometres per second). This seems like an amazing speed. A speed almost unimaginable, but with relative to the speed of light (The cosmological speed limit) we are only talking about 1% that of the speed of light, these planets and stars are travelling at a fraction of the speed of light.

Currently objects that are currently orbiting around the SMBH are in a motion called precession, a special formation that takes place when going around high mass objects. This for the most part is able to be calculated with using the Theory of Relativity but for this instant it is proving difficult since the object themselves are going through a different type of precession that is hard to calculate and it is proving difficult to differentiate between the two types.

The particular objects known as the S0-102 was detected at the Keck Observatory in Hawaii, using the twin-mounted 10 meter telescope, equipped with laser guiding technology and adaptive optics which all allow for distortions to be corrected which could happen due to the earth’s atmosphere.
Currently the work is still in progress. But this event will unlikely cause any serious damage to the heralded theory conjured up by one of our greatest scientists in history. A theory that has stood against the elements for over half a century.

Radius of a Black Hole Measured and First Direct Image of Black Hole

Just recently scientists have been able to measure the radius of black holes. No easy feat of technical prowess, for scientists to look at the Super Massive black hole in the galaxy M87 (A Distant Galaxy). This SMBH is 6 million times more dense than our local sun, which is expected as Black Holes collapse under its own gravitation force and compress into singularities allowing them to swallow anything that enters its region. Normally the cause of star systems to localise around one reference point, with the galaxy being so large, the densest object will take rule over anything else in the region, gravitationally, thus making everything else literally revolve around it


The radius of the Black Hole was measured using a special analytical tool called the Event Horizon Telescope (EHT), situated in three locations, being Hawaii, California and Arizona. The data that was obtained from these telescopes was algamated to create a more advanced and more detailed picture (very high resolution) detailing the Black Hole and its apparent accretion disk. As a result of this joint effort, scientists were able to view directly, matter entering towards the event horizon at the edge of the black hole.

The Astronomers were able to identify the radius length of the black hole, by being able to observe and study the jets of energy-excited matter, that was being evacuated from the Black Hole, which was travelling at near speed of light. The super-fast matter leaving the Black Hole is caused by super heating the accretion disk (Matter surrounding the black holes event horizon). The Black Holes rotation and the matter particles that are surrounding it make a powerful electro-magnetic field. This field would cause the Black Hole to spit out hot matter and shoot it across the galaxy, perhaps even further.
Though this hasn’t been the first time that matter has been sprung from the M87s Black Hole. The Hubble Space Telescope captured images of piping hot jets emitting in 1998. Though with the inadequate resolution the Hubble was not able to make a precise measurement that were needed to factor the size of the Black Hole and its accretion disk.
After stringent calculations, scientists have determined that the accretions disks currently are about 5.5 times bigger than the Black Hole itself. This is then given an estimation of the radius of the Black Hole using smart mathematical techniques.
The new EHT will be adding new technology to the its inventory station array, which will grant more precise measurements and advanced resolutions allowing Astronomers to clarify and/or verify scientific theories about the behaviour of Black Holes. More importantly, grant a new light in to Einstein’s theory of Relativity determine whether Einstein was correct all those years ago or not!
