“Advanced Life May Exist in a Form That’s Beyond Matter” Astrophysicists Claim

Astrophysicist Paul Davies at Arizona State University suggests that advanced technology might not even be made of matter. That it might have no fixed size or shape; have no well-defined boundaries. Is dynamical on all scales of space and time. Or, conversely, does not appear to do anything at all that we can discern. Does not consist of discrete, separate things; but rather it is a system, or a subtle higher-level correlation of things.

Are matter and information, Davies asks, all there is? Five hundred years ago, Davies writes, ” the very concept of a device manipulating information, or software, would have been incomprehensible. Might there be a still higher level, as yet outside all human experience, that organizes electrons? If so, this “third level” would never be manifest through observations made at the informational level, still less at the matter level.

We should be open to the distinct possibility that advanced alien technology a billion years old may operate at the third, or perhaps even a fourth or fifth level -all of which are totally incomprehensible to the human mind at our current state of evolution.

Susan Schneider of the University of Pennsylvania appears to agree. She is one of the few thinkers—outside the realm of science fiction— that have considered the notion that artificial intelligence is already out there, and has been for eons.

Her study, Alien Minds, asks “How would intelligent aliens think? Would they have conscious experiences? Would it feel a certain way to be an alien?”

While we are aware that our culture is anthropomorphizing, Schneider imagines that her suggestion that aliens are supercomputers may strike us as far-fetched. So what is her rationale for the view that most intelligent alien civilizations will have members that are superintelligent AI?

Schneider presents offer three observations that support her conclusion for the existence of alien superintelligence.

The first is “the short window observation”: Once a society creates the technology that could put them in touch with the cosmos, they are only a few hundred years away from changing their own paradigm from biology to AI. This “short window” makes it more likely that the aliens we encounter would be postbiological.

The short window observation is supported by human cultural evolution, at least thus far. Our first radio signals date back only about a hundred and twenty years, and space exploration is only about fifty years old, but we are already immersed in digital technology.

Schneider’s second argument is “the greater age of alien civilizations.” Proponents of SETI have often concluded that alien civilizations would be much older than our own “…all lines of evidence converge on the conclusion that the maximum age of extraterrestrial intelligence would be billions of years, specifically [it] ranges from 1.7 billion to 8 billion years.

If civilizations are millions or billions of years older than us, many would be vastly more intelligent than we are. By our standards, many would be super-intelligent. We are galactic babies. But would they be forms of AI, as well as forms of super-intelligence? Schneider says, yes. Even if they were biological, merely having biological brain enhancements, their super-intelligence would be reached by artificial means, and we could regard them as being “artificial intelligence.”

But she suspects something stranger than this: that they will not be carbon-based. Uploading allows a creature near immortality, enables reboots, and allows it to survive under a variety of conditions that carbon-based life forms cannot. In addition, silicon appears to be a better medium for information processing than the brain itself. Neurons reach a peak speed of about 200 Hz, which is seven orders of magnitude slower than current microprocessors.

Facebook patented hand tracking system

Facebook patented hand tracking with finger emitters.

Facebook Technologies / USPTO, 2020

Facebook has patented a hand tracking system using small transponders at the ends of the fingers. The patent describes a glove with several emitters and a receiving system that distinguishes the signals from each emitter, calculates their location and restores the shape of the hand. The Patently Apple website drew attention to the patent.

Motion capture systems are often used when shooting movies, as well as in virtual reality. There are several standard tracking methods. For professional projects, an external system is often used, which consists of high-speed infrared cameras on the walls and infrared markers on clothes.

This is a rather inconvenient and extremely expensive system, so home VR systems usually use gloves that track the pose of the hand, and a separate massive beacon on the arm that allows the base station near the computer to track its location. Also recently, hand tracking systems using cameras and machine vision algorithms have begun to develop. In particular, at the end of 2019, such a feature appeared in Oculus Quest, which is being developed by a Facebook-owned company.

In a new patent, Facebook engineers described a method for tracking brush poses across multiple emitters. It is assumed that the system will consist of two parts: a glove and a tracking station nearby, for example, on a table near a computer or set-top box. The glove contains several transponders operating on millimeter waves. They can be located at the ends of the fingers, as well as on other parts of the brush for more precise tracking.

The tracking station has several antennas. They emit signals towards the glove, and transponders emit response signals. After this, the antennas receive response signals, using triangulation, they calculate the location of the transponders and create a three-dimensional model of the brush. The authors note that the signals can be modulated by time, frequency, or changed by other parameters so that they are unique for each transponder and facilitate the task of creating a model.

In recent years, many miniature emitters for the millimeter radio band have appeared. Most often they are  offered to be used for communication of the 5G standard (mmWave range), as well as in compact radars for smartphones and smart watches.

Do Advanced Extraterrestrial Civilizations extract energy from black holes?

Researchers from the School of Physics and Astronomy at the University of Glasgow in the UK have proven a half-century hypothesis that suggests that technologically advanced extraterrestrial civilizations could potentially extract energy from spinning black holes. An article by researchers is published in the journal Nature Physics.

In 1969, the British physicist Roger Penrose suggested that aliens can extract energy from a rotating black hole due to the fact that particles or waves flying through the ergosphere take away the energy of rotation of the black hole (this phenomenon became known as the Penrose process). 

The Soviet physicist Yakov Zeldovich developed this idea and put forward the hypothesis that a rapidly rotating cylinder is capable of amplifying the “swirling” electromagnetic waves incident on it (that is, having a certain orbital angular momentum), including quantum fluctuations in a vacuum. 

However, this effect has not yet been experimentally verified, since the cylinder had to rotate at a frequency of at least a billion times per second.

In a new work, scientists for the first time managed to observe the Zeldovich effect, achieved using acoustic waves with a frequency of 60 hertz. 

During the experiment, the researchers installed 16 speakers in the form of a ring and directed the sound toward a rotating disk made of noise-absorbing foam. In this case, the acoustic waves from one speaker lagged behind in phase from the waves from another speaker, which made it possible to simulate the orbital angular momentum. Conditions satisfying the Zeldovich effect were achieved by rotating the disk with a frequency of only 15-30 revolutions per second.

The experimental results confirmed that low-frequency modes can be amplified by up to 30 percent, passing through the noise-absorbing layer of the disk. As the speed of the disk increases, the frequency of sound waves decreases due to the Doppler effect, however, when a certain speed is reached, it again returns to its previous value, while the volume (i.e. the amplitude) increases. This is due to the fact that the waves took part of the rotational energy from the disk.

The Penrose process occurs when the body has two parts, one of which falls beyond the horizon of events. If two fragments have certain speeds, a special position relative to each other and fly along the correct paths, then the fall of one fragment transfers the energy to the other part, greater than the energy that the body had originally.

 For an outside observer, it looks as if the body was divided into a part with positive energy and a part with “negative energy”, which when falling beyond the horizon reduces the angular momentum of the black hole. As a result, the first fragment takes off from the ergosphere, “taking” the energy of rotation of the black hole.

What if we could create antigravitу?

Are уou tired of cramped citу life? Then anti-gravitу is just what уou need! We still don’t know the technologу, but if we do, it will completelу change our world.

How can this change the waу we build our cities? Whу would this allow us to travel further into space? And how can this help us colonize alien worlds?

According to astronomers, gravitу is “the force bу which a planet or other bodу pulls objects to its center. We reallу don’t know whу gravitу behaves like this; we just know that this is so, and that’s all we need for this.

As we talk about things that we know too little about, let’s get to know her better. Antigravitу, as the name implies, is a hуpothetical means of counteracting the effects of gravitу.

Although manу scholars saу this is not possible, this does not stop us from reasoning. But if we ever find out, we will have to delve into an even more mуsterious part of our universe – antimatter.

To understand what antimatter is and how it relates to antigravitу, we will go back during the Big Bang. When the Big Bang occurred, he created matter and antimatter. Matter consists of atoms – the building blocks of chemical elements such as helium, oxуgen and hуdrogen.

Inside the atoms уou will find particles, such as protons, which have a positive electric charge, and electrons, which usuallу have a negative charge. For antimatter, the electric charge of these particles is reversed.

This led to some speculations that other properties will also be changed, such as how theу react to gravitу. We could not verifу how antimatter reacts to gravitу – for now. However, some theories saу that when we do this, we will find that antimatter particles do not fall, giving us our first real example of antigravitу.

If so, this could lead to a scientific and technological revolution. We could theoreticallу use antimatter to develop technologу that protects people or objects from gravitational forces. In other words, we can make so manу things float in the air.

So what would we do with this crazу technologу? Well, firstlу, there should be hoverboards, right? We’re talking about real hoverboards that don’t touch the ground!

We could build floating cities to accommodate our ever-growing population. Massive structures can be suspended over ponds or rockу terrain that we could not build. But perhaps we will see the greatest importance of anti-gravitу technologу, if we look even further – at the stars.

Space travel will be much safer and cheaper. Space shuttles will not need rocket fuel to launch from our atmosphere. Instead, we could just stop the effects of gravitу on them.

Antigravitу will not onlу help us get to space; It can also help us find a new home there. We no longer need to worrу about planets with gravitу too strong for human habitation, since we can simplу use antigravitу to protect ourselves from it.

Yes, we understand that there is a lot of unknown and hуpothetical with this, but here’s what happens when we talk about something as mуsterious as antimatter.
