Is Consciousness First in Virtual Reality?

Posted by in categories: neuroscience, physics, virtual reality

The prevailing scientific paradigm is that matter is primary and everything, including consciousness can be derived from the laws governing matter. Although the scientific explanation of consciousness on these lines has not been realized, in this view it is only a matter of time before consciousness will be explained through neurobiological activity in the brain, and nothing else. There is an alternative view that holds that it is fundamentally impossible to explain how subjectivity can arise solely out of material processes-“the hard problem of consciousness”-and instead consciousness should be regarded in itself as a primary force in nature. This view attempts to derive, for example, the laws of physics from models of consciousness, instead of the other way around. While as scientists we can understand and have an intuition for the first paradigm, it is very difficult to understand what “consciousness is primary” might mean since it has no intuitive scientific grounding. Here we show that worlds experienced through virtual reality (VR) are such that consciousness is a first order phenomenon. We discuss the Interface Theory of Perception which claims that in physical reality perceptions are not veridical and that we do not see the “truth” but that perception is based on evolutionary payoffs. We show that this theory may provide an accurate description of perception and consciousness within VR, and we put forward an experimental study that could throw light on this. We conclude that VR does offer an experimental frame that provides intuition with respect to the idea that “consciousness is first” and what this might mean regarding the perceived world. However, we do not draw any conclusions about the veracity of this notion with respect to physical reality or question the emergence of consciousness from brain function.

Observer Theory

Posted by in categories: physics, space

Philosophy of science.


We call it perception. We call it measurement. We call it analysis. But in the end it’s about how we take the world as it is, and derive from it the impression of it that we have in our minds.

We might have thought that we could do science “purely objectively” without any reference to observers or their nature. But what we’ve discovered particularly dramatically in our Physics Project is that the nature of us as observers is critical even in determining the most fundamental laws we attribute to the universe.

Space telescope spots ‘superflares’ 10,000 times brighter than Sun — Study

Posted by in categories: energy, physics, space

Scientists have developed a model to better understand the physics of the powerful superflares emitted by stars far beyond our solar system.

Solar flares, which are rapid and strong bursts of energy and radiation that originate from the Sun’s surface, are known to be emitted into space by our Sun.

NASA’s Kepler and TESS missions, however, have discovered several stars may produce superflares that are 100–10,000 times brighter than those emitted by our Sun.

Prepare Our Kids for Life, Not Standardized Tests | Ted Dintersmith | TEDxFargo

Posted by in categories: economics, education, employment, finance, physics, robotics/AI

As a leading venture capitalist, Ted Dintersmith lived and breathed the world of innovation. He has seen first-hand how quickly automation is eliminating the structured jobs in our economy, as well as the opportunities for young adults who are bold, creative, and entrepreneurial. As Ted shifted his focus to the future of our schools, he realized that the core purpose of our schools has been lost in a wave of testing, data, and accountability. In this talk, Ted underscores the potential for our kids and our country if we educate to our innovative and creative strengths, and trust our schools and teachers to prepare our kids for life, instead of for standardized tests.

After a twenty-five year career in venture capital, Ted Dintersmith is now focused on issues at the intersection of innovation and education. In the fall of 2012, Ted served as part of the delegation representing the United States at the United Nations General Assembly, where he focused on global education and entrepreneurship. The first two films he executive produced – Most Likely To Succeed and The Hunting Ground – premiered at Sundance, 2015. His website http://www.edu21c.com describes his initiatives and he can be followed @dintersmith.

Crisis in Cosmology: New Study Exacerbates Expansion Rate Disagreement

Posted by in categories: cosmology, physics

The current measurements of the expansion rate of the universe are in disagreement, leading to a crisis in cosmology and the need for renewed research efforts into new physics and a new model of the universe.

Questions to inspire discussion.

Black holes really just ever-growing balls of string, researchers say

Posted by in categories: cosmology, physics

Black holes aren’t surrounded by a burning ring of fire after all, suggests new research.

Some physicists have believed in a “firewall” around the perimeter of a black hole that would incinerate anything sucked into its powerful gravitational pull.

But a team from The Ohio State University has calculated an explanation of what would happen if an electron fell into a typical black hole, with a mass as big as the sun.

Gravitational waves rippling from black hole merger could help test general relativity

Posted by in categories: cosmology, physics

Scientists have discovered gravitational waves stemming from a black hole merger event that suggest the resultant black hole settled into a stable, spherical shape. These waves also reveal the combo black hole may be much larger than previously thought.

When initially detected on May 21, 2019, the gravitational wave event known as GW190521 was believed to have come from a merger between two black holes, one with a mass equivalent to just over 85 suns and the other with a mass equivalent to about 66 suns. Scientists believed the merger therefore created an approximately 142 solar mass daughter black hole.

Yet, newly studied spacetime vibrations from the merger-created black hole, rippling outward as the void resolved into a proper spherical shape, seem to suggest it’s more massive than initially predicted. Rather than possess 142 solar masses, calculations say it should have a mass equal to around 250 times that of the sun.
