Immortality by 2045? Scientists: Not only possible, but inevitable!

According to several thinkers, scientists, and inventors human immortality by 2045 or even as early as 2029 is not only possible, but it is inevitable. They all are currently exploring different paths to achieve this goal and are looking for more public support as well as public debate of this issue, but surprisingly there isnt that much of it going on right now. Given the social, political, moral, and spiritual implications of these coming new biotechnological breakthroughs and how radically they can change the lives of each and everyone of us, I believe that we all need to give this some thought, or we will be swept off our feet by all the changes that will come upon us within the next couple of decades.
In February of 2011 Time Magazine published a feature article titled, 2045: The Year Man Becomes Immortal, which described the predictions of a very well known inventor and currently Googles Director of Engineering Ray Kurzwail, who argues for some time now that we are about to approach what is called a singularity point due to exponential power of computing that we already possess beyond which we will surpass all biological limitations as a species including that of mortality.
Kurzwail envisions humanity being able to cure all major diseases such as cancer and diabetes through explosion in medical innovations for example through nano technology and robotic implants, the latter of which he points out that we are already doing, giving as an example the pacemaker for people with heart disease and brain implants for people with Parkinsons disease.
In the future he sees us merging more and more with the increasingly powerful and intelligent machines that will serve as an extension of ourselves into an infinite future though he dislikes the term often used for it transhumanism, because he argues that this will not make us lose our humanity, but will enhance it, though many other people do not see it in such a positive way.
Kurzweil concedes to his critics that such technology as any other one invented by mankind will be a double edged sword and could be used for evil, but he warns that trying to stop it will only force it underground and thus make it even more dangerous. Instead he suggests that we must keep it all in the open and develop ways to harness it for good.
Instead of merging with the machines or transferring our consciousness onto them in order to live forever, Dr. Aubrey de Grey is working on ways that we could simply repair any damage caused by natural aging process at the cellular level. He likens it to car maintenance through which we can allow a machine (our body) that would otherwise fall into disrepair, function well way beyond its intended lifespan, so to speak.
Grey sees it as a natural consequence of medical science and technologys striving to cure illnesses. He says that when we are able to cure damage caused by aging, we will prevent the development of any disease in the first place and thus prevent death due to these damages. Therefore according to Grey, immortality will be simply a by-product of our ability to repair any damages in our bodies.
This of course will not eliminate death by car accidents, starvation, murders and wars, but it will allow people to live up to hundreds of years of age or even more. He predicts that even if we start doing those maintenance sessions on people in 20 years, this will allow them to live well until the next session by which time the technology will have improved and that individual then would be able to have his biological clock set to 40 years prior and would thus have his life extended by double that amount with each maintenance session extending life further and further.
While I am very wary of the Kurzweils road to longevity, I see the way of Aubrey de Grey as more plausible and less spiritually controversial as it would not alter our God given genetic code whatsoever. I can already see how great of a difference to aging process simple lifestyle choices and nutrition can make. A couple of weeks ago I looked through a family album and at one of my Moms pictures. I realized that she was only 31 when this particular picture was taken and that I am now older than she was back then, but I look at least 10 years younger! And it wasnt only my opinion. Some other family members and friends said the same thing, which means that due to my healthy lifestyle, I am aging at much slower rate than my Mom. My Mom started to smoke, drink alcohol socially at age twenty as well as from even younger age she was very much given to sun tanning, all of which I dont do, hence I am doing less damage to my body and age slower.
So, how big a difference these maintenance sessions could make? I think they could extend life spans greatly, especially if they start early in life. It sounds at once very scary and very exciting, depending on which road into the future we will take, but as these experts point out it is coming upon us and coming soon. We cannot escape it and we should take an active role in discussing these issues and its implications sooner, rather than later.

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.
