Half-life of xenon 124 is about 18 sextillion years

Posted by in category: futurism

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.

What number comes after a Googolplex?

Posted by in category: futurism

A googolplex is 1010^100, where the exponents are solved from the right. The exponentiation symbol (^) means the number just to the left multiplied by the left number’s self the number just to the right number of times. If the left number is 10, that means 1 followed by the right number of zeros. That is 10googol=1010,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000. So the answer to your question is a-googolplex-and-1=(1010^100)+1.

Moss capable of removing arsenic from drinking water discovered

Posted by in category: sustainability

Circa 2018

A moss capable of removing arsenic from contaminated water has been discovered by researchers from Stockholm University. And it happens quickly — in just one hour, the arsenic level is so low that the water is no longer harmful for people to drink. The study has been published in the journal Environmental Pollution.

The aquatic moss Warnstofia fluitans, which grows in northern Sweden, has the ability to quickly absorb and adsorb arsenic from water. The discovery allows for an environmentally friendly way to purify water of arsenic. One possible scenario is to grow the moss in streams and other watercourses with high levels of arsenic.

Researchers successfully sent a simulated elementary particle back in time

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

The results are fascinating and spur the imagination, but don’t start investing in flux capacitors yet. This experiment also shows us that sending even a simulated particle back in time requires serious outside manipulation. To create such an external force to manipulate even one physical particle’s quantum waves is well beyond our abilities.

“We demonstrate that time-reversing even ONE quantum particle is an unsurmountable task for nature alone,” study author Vinokur wrote to the New York Times in an email [emphasis original]. “The system comprising two particles is even more irreversible, let alone the eggs — comprising billions of particles — we break to prepare an omelet.”

A press release from the Department of Energy notes that for the “timeline required for [an external force] to spontaneously appear and properly manipulate the quantum waves” to appear in nature and unscramble an egg “would extend longer than that of the universe itself.” In other words, this technology remains bound to quantum computation. Subatomic spas that literally turn back the clock aren’t happening.

Physicists invent flux capacitor, break time-reversal symmetry

Posted by in categories: futurism, quantum physics

In the popular movie franchise “Back to the Future”, an eccentric scientist creates a time machine that runs on a flux capacitor.

Now a group of actual physicists from Australia and Switzerland have proposed a device which uses the tunneling of around a capacitor, breaking time-reversal symmetry.

The research, published this week in Physical Review Letters, proposes a of electronic circulators, which are devices that control the direction in which microwave signals move.

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.
