There’s a Brand-New Kilogram, And It’s Based on Quantum Physics

Posted by in categories: alien life, particle physics, quantum physics

The kilogram isn’t a thing anymore. Instead, it’s an abstract idea about light and energy.

As of today (May 20), physicists have replaced the old kilogram — a 130-year-old, platinum-iridium cylinder weighing 2.2 pounds (1 kilogram) sitting in a room in France — with an abstract, unchanging measurement based on quadrillions of light particles and Planck’s constant (a fundamental feature of our universe).

In one sense, this is a grand (and surprisingly difficult) achievement. The kilogram is fixed forever now. It can’t change over time as the cylinder loses an atom here or an atom there. That means humans could communicate this unit of mass, in terms of raw science, to space aliens. The kilogram is now a simple truth, an idea that can be carried anywhere in the universe without bothering to bring a cylinder with you.

Scientists: Pluto May be Hiding Alien Life in Buried Oceans

Posted by in categories: alien life, habitats

The discovery could mean that other inhospitable habitats may potentially harbor life.

This could mean there are more oceans in the universe than previously thought, making the existence of extraterrestrial life more plausible.

The Thesis on Consciousness and Experiential Realism: Digital Philosophy Perspective

Posted by in categories: alien life, computing, information science, quantum physics

A radically new view articulated now by a number of digital philosophers is that consciousness, quantum computational and non-local in nature, is resolutely computational, and yet, has some “non-computable” properties. Consider this: English language has 26 letters and about 1 million words, so how many books could be possibly written in English? If you are to build a hypothetical computer containing all mass and energy of our Universe and ask it this question, the ultimate computer wouldn’t be able to compute the exact number of all possible combinations of words into meaningful story-lines in billions of years! Another example of non-computability of combinatorics: if you are to be born and live your own life again and again in our Quantum Multiverse, you could live googolplex (10100) lives, but they all would be somewhat different — some of them drastically different from the life you’re living right now, some only slightly — never quite the same, and timeline-indeterminate.

Another kind of non-computability is akin to fuzzy logic but based on pattern recognition. Deeper understanding refers to a situation when a conscious agent gets to perceive numerous patterns in complex environments and analyze that complexity from the multitude of perspectives. That is beautifully encapsulated by Isaiah Berlin’s quote: “To understand is to perceive patterns.” The ability to recognize patterns in chaos is not straightforwardly algorithmic but rather meta-algorithmic and yet, I’d argue, deeply computational. The types of non-computability that I just described may somehow relate to the non-computable element of quantum consciousness to which Penrose refers in his work.

Half-life of xenon 124 is about 18 sextillion years

Posted by in category: alien life

A new finding puts the half-life of xenon 124 close to 18 sextillion years.

That’s 18,000,000,000,000,000,000,000.

Existing theory predicts the isotope’s radioactive decay has a half-life that surpasses the age of the universe “by many orders of magnitude,” but no evidence of the process has appeared until now.

The Kardashev Scale – Type I, II, III, IV & V Civilization

Posted by in category: alien life

We have reached a turning point in society. According to renowned theoretical physicist Michio Kaku, the next 100 years of science will determine whether we perish or thrive. Will we remain a Type 0 civilization, or will we advance and make our way into the stars?

Experts assert that, as a civilization grows larger and becomes more advanced, its energy demands will increase rapidly due to its population growth and the energy requirements of its various machines. With this in mind, the Kardashev scale was developed as a way of measuring a civilization’s technological advancement based upon how much usable energy it has at its disposal (this was originally just tied to energy available for communications, but has since been expanded).

The scale was originally designed in 1964 by the Russian astrophysicist Nikolai Kardashev (who was looking for signs of extraterrestrial life within cosmic signals). It has 3 base classes, each with an energy disposal level: Type I (10¹⁶W), Type II (10²⁶W), and Type III (10³⁶W). Other astronomers have extended the scale to Type IV (10⁴⁶W) and Type V (the energy available to this kind of civilization would equal that of all energy available in not just our universe, but in all universes and in all time-lines). These additions consider both energy access as well as the amount of knowledge the civilizations have access to.

Can We Now Predict When A Neutron Star Will Give Birth To A Black Hole?

Posted by in category: alien life

A neutron star is perhaps one of the most awe-inspiring and mysterious things in the Universe. Composed almost entirely of neutrons with no net electrical charge, they are the final phase in the life-cycle of a giant star, born of the fiery explosions known as supernovae. They are also the densest known objects in the universe, a fact which often results in them becoming a black hole if they undergo a change in masspace and science black hole is in space science

For some time, astronomers have been confounded by this process, never knowing where or when a neutron star might make this final transformation. But thanks to a recent study by a team of researchers from Goethe University in Frankfurt, Germany, it may now be possible to determine the absolute maximum mass that is required for a neutron star to collapse, giving birth to a new black hole. space and science black hole is in space science

As with everything else relating to neutron stars, the process by which they become black holes has long been a source of fascination and bewilderment for astronomers. As the densest of all objects in the known universe, their mass cannot grow without bound – meaning that any increase in mass will also cause an increase in their density. space and science black hole is in space science.

Here’s why scientists think discovering aliens is inevitable and imminent

Posted by in categories: alien life, chemistry

Amino acids, just like those that make up every protein in our bodies, have been found in the tails of comets.

Because, following a string of remarkable discoveries over the past two decades, the idea of alien life is not as far-fetched as it used to seem.

Discovery now seems inevitable and possibly imminent.

What happened before the Big Bang?

Posted by in categories: alien life, evolution, physics

In trying to answer such questions, scientists bump up against the limits of the laws of physics. Existing theories can account for the evolution of the universe from its earliest moments — from a fraction of a second after the Big Bang — but the question of what came before has been among the most vexing in all of science.

“It’s my life’s work to try to answer that question,” University of Toronto physicist Renée Hložek says.

This image represents the evolution of the universe, starting with the Big Bang. The red arrow marks the flow of time.
