Supernova reveals its secrets to team of astronomers

Posted by in categories: cosmology, time travel

An international group of astronomers led by Benjamin Thomas of The University of Texas at Austin has used observations from the Hobby-Eberly Telescope (HET) at the university’s McDonald Observatory to unlock a puzzling mystery about a stellar explosion discovered several years ago and evolving even now. The results, published in today’s issue of The Astrophysical Journal, will help astronomers better understand the process of how massive stars live and die.

When an is first detected, astronomers around the world begin to follow it with telescopes as the light it gives off changes rapidly over time. They see the light from a supernova get brighter, eventually peak, and then start to dim. By noting the times of these peaks and valleys in the light’s brightness, called a “,” as well as the characteristic wavelengths of light emitted at different times, they can deduce the physical characteristics of the system.

“I think what’s really cool about this kind of science is that we’re looking at the emission that’s coming from matter that’s been cast off from the progenitor system before it exploded as a supernova,” Thomas said. “And so this makes a sort of time machine.”

A universe of 10 dimensions

Posted by in categories: cosmology, particle physics, quantum physics

Circa 2014 o.o!


When someone mentions “different dimensions,” we tend to think of things like parallel universes – alternate realities that exist parallel to our own, but where things work or happened differently. However, the reality of dimensions and how they play a role in the ordering of our Universe is really quite different from this popular characterization.

To break it down, dimensions are simply the different facets of what we perceive to be reality. We are immediately aware of the three dimensions that surround us on a daily basis – those that define the length, width, and depth of all objects in our universes (the x, y, and z axes, respectively).

On gravitational preheating

Posted by in categories: cosmology, particle physics

We consider dark matter production during the inflaton oscillation epoch. It is conceivable that renormalizable interactions between dark matter and inflaton may be negligible. In this case, the leading role is played by higher dimensional operators generated by gravity and thus suppressed by the Planck scale. We focus on dim-6 operators and study the corresponding particle production in perturbative and non-perturbative regimes. We find that the dark matter production rate is dominated by non-derivative operators involving higher powers of the inflaton field. Even if they appear with small Wilson coefficients, such operators can readily account for the correct dark matter abundance.

The universe could stop expanding ‘remarkably soon’, study suggests

Posted by in category: cosmology

Recent Study on the effects of Dark Energy suggests expansion of the universe could in fact slow down and eventually reverse itself to eventually result in a “Big Crunch” billions of years from now. Such a theory had been proposed in the past but was previously rejected due to observed accelerating expansion attributed to Dark Energy.


The universe may stop expanding in just 100 million years if dark energy decays over time, a new study suggests.

The Hollywood A.I.-I.P. Supernova

Posted by in categories: cosmology, entertainment, robotics/AI

AI take over of entertainment industry by about 2030. Already starting, and already messy.


Will the robots replace us all one day? Who knows, but chances are they will eventually learn how to create a superhero movie. Ergo, the start of one of the great legal debates in Hollywood history.

Hear the Eerie Sounds of a Black Hole Echo — Search Reveals 8 New Sources of Black Hole Echoes

Posted by in category: cosmology

New findings will help scientists trace a black hole.

A black hole is a place in space where the pull of gravity is so strong not even light can escape it. Astronomers classify black holes into three categories by size: miniature, stellar, and supermassive black holes. Miniature black holes could have a mass smaller than our Sun and supermassive black holes could have a mass equivalent to billions of our Sun.

The Tesseract: between mediated consciousness and embodiment

Posted by in categories: cosmology, neuroscience, physics

Abstract

As a sensate infrastructure, the body conveys information to and from the brain to complete a perceptual concordance with consciousness. This system of reciprocal communication both positions consciousness in spacetime, and allows that consciousness is dependent upon the body to roam. Through movement we comprehend. The corporeal occupation of spacetime permits human consciousness access to the phenomena of its physical environment, whereby it uses language (utterance) to both construct and describe this existence. This mediated transmission evolved into story and narrative in an attempt to apprehend, control and more importantly convey what is perceived. It is precisely the components of space and time, critical elements to our own existence that play such a paramount role in our ability to generate meaning and narrative comprehension. As our dimensional understanding has evolved and extended, so too has our understanding that space and time are crucial components of narrative. With the emergence of auxiliary narrative spaces, this movement of consciousness affords opportunities to create new narrative imperatives. In the theoretical realm of physics, the tesseract makes it possible to overcome the restraints of time. The tesseract is a gravitational wormhole that represents the physical compression of space that circumvents time in order to move from one location in spacetime to another. The index, as part of the body, but also the mechanism for applying a collapsed signification, requires both utterance (mediation) and event (temporal-frame) in order to create cognitive meaning. The indexical functions as a linguistic tesseract that collapses language creating a bridge over the semantic divide between utterance and meaning. This paper places the function and potential of the tesseract within the paradigm of cognitive narratology through the argument that compression is the mechanism for narrative construction of story, autopoiesis, and the locality of self.

Here’s Why Hibernation in Space May Not Be Possible For Humans After All

Posted by in categories: cosmology, space travel

Sending humans virtually anywhere in space beyond the Moon pushes logistics of health, food, and psychology to limits we’re only just beginning to grasp.

A staple solution to these problems in science fiction is to simply put the void-travelers to bed for a while. In a sleep-like state akin to hibernation or torpor, metabolism drops, and the mind is spared the boredom of waiting out endless empty hours.

Unlike faster-than-light travel and wormholes, the premise of putting astronauts into a form of hibernation feels like it’s within grasp. Enough so that even the European Space Agency is seriously looking into the science behind it.

Cybernetic Theory: Interpretive Model of Everything We Call the Universe

Posted by in categories: computing, cosmology, neuroscience, quantum physics

Another key insight of Cybernetic Theory can be referred to as “Mind Over Substrates”: Phenomenal “local” mind is “cybernetically” emergent from the underlying functional organization, whereas holistic “non-local” consciousness is transcendentally imminent. Material worlds come and go, but fundamental consciousness is ever-present, as the multiverse ontology is shown to be testable. From a new science of consciousness to simulation metaphysics, from evolutionary cybernetics to computational physics, from physics of time and information to quantum cosmology, this novel explanatory theory for a deeper understanding of reality is combined into one elegant theory of everything (ToE).

If you’re eager to familiarize with probably the most advanced ontological framework to date or if you’re already familiar with the Syntellect Hypothesis which, with this newly-released series, is now presented to you as the full-fledged Cybernetic Theory of Mind, then this 5-book set will surely present to you some newly-introduced and updated material if compared with the originally published version and can be read as a stand-alone work just like any book of the series:
