Could Time Travel Soon Become a Reality? Physicists Simulate Sending Quantum light Particles into the Past

Posted by in categories: evolution, particle physics, quantum physics, time travel

If a time traveler went back in time and stopped their own grandparents from meeting, would they prevent their own birth?

That’s the crux of an infamous theory known as the ‘grandfather paradox’, which is often said to mean time travel is impossible — but some researchers think otherwise. A group of scientists have simulated how time-travelling photons might behave, suggesting that, at the quantum level, the grandfather paradox could be resolved.

The research was carried out by a team of researchers at the University of Queensland in Australia and their results are published in the journal Nature Communications. The study used photons — single particles of light — to simulate quantum particles travelling back through time. By studying their behavior, the scientists revealed possible bizarre aspects of modern physics.

Worm research in life extension leads scientists to discover new metric to track aging

When researchers at The Scripps Research Institute (TSRI) in California administered an antidepressant called mianserin to the Caenorhabditis elegans roundworm in 2007, they discovered the drug increased the lifespan of the “young adulthood” of roundworms by 30–40 per cent.

So, does that mean it will work in humans? Not necessarily. “There are millions of years of evolution between worms and humans,” says TSRI researcher Michael Petrascheck. “We may have done this in worms, but we don’t want people to get the impression they can take the drug we used in our study to extend their own teens or early twenties.”

Risks of mass toying with genes addressed at Cambridge conference

Posted by in categories: biotech/medical, engineering, evolution, robotics/AI

While the global academic discussion focuses on the coverage of existential risks associated with the rise of a Skynet equivalent artificial intelligence; it is worth mentioning that there are divergent advances in biotech whichare as alarming and urgent as the rise of an all omnipotent and omnipresent AI. Those issues should be directed and scanned under a microscope because they are at our doorstep. We should note that the application of “wind tunnelling” towards new technologies is necessary to prepare for the future, and subsequently, we should mitigate the risks and anticipate the greatest threats associated with technology XYZ as well as the biggest opportunities.

If we recall the year 2011, virologist Ron Fouchier presented his enhanced version of the H5N1 which could create a pandemic of massive impact wiping out half the world population if not more. Fouchier was experimenting with the avian flu virus searching for virulence enhancing evolution paths. What he did is spread the virus throughout a population of ferrets, and it reproduced with an increase in its ability to adapt at each transformation; in ten generations, the airborne version gained so much in virility that it had the potential power to kill half of the human population.

A year after that, in 2012, CRISPR/Cas9 genome engineering/editing tool was first shown to work in human cell culture. It allows scientists to edit genomes which binds and splices DNA at specific locations. The complex can be programmed to target a problematic gene, which is then replaced or repaired by another molecule introduced at the same time. A highly precise method. In the past years there has been much researchwere many researches conducted, e.g. the first monkeys with targeted mutations were born, and even editing methods for preventing HIV-1 infection in humans. What this means is the introduction of a complex randomness factor. If in the past a handful of people had access to genomic iterations and experimentation; now this fact is about to be change, releasing the proverbial genie from the bottle, with little ability to control it.

Can Artificial Intelligence Be Taught?

Posted by in categories: bioengineering, evolution, machine learning, robotics/AI, science

In spite of the popular perception of the state of artificial intelligence, technology has yet to create a robot with the same instincts and adaptability as a human. While humans are born with some natural instincts that have evolved over millions of years, Neuroscientist and Artificial Intelligence Expert Dr. Danko Nikolic believes these same tendencies can be instilled in a robot.

“Our biological children are born with a set of knowledge. They know where to learn, they know where to pay attention. Robots simply can not do that,” Nikolic said. “The problem is you can not program it. There’s a trick we can use called AI Kindergarten. Then we can basically interact with this robot kind of like we do with children in kindergarten, but then make robots learn one level lower, at the level of something called machine genome.”

Programming that machine genome would require all of the innate human knowledge that’s evolved over thousands of years, Nikolic said. Lacking that ability, he said researchers are starting from scratch. While this form of artificial intelligence is still in its embryonic state, it does have some evolutionary advantages that humans didn’t have.

“By using AI Kindergarten, we don’t have to repeat the evolution exactly the way evolution has done it,” Nikolic said. “This experiment has been done already and the knowledge is already stored in our genes, so we can accelerate tremendously. We can skip millions of failed experiments where evolution has failed already.”

This Is What it Looks Like When a Black Hole Shreds a Star

Posted by in categories: cosmology, evolution

When a star wanders too close to a black hole, immense gravitational forces begin to rip it apart in an epic cosmic slaying called a “tidal disruption event.” Some of the star’s mass is flung outward into space, while the rest is drawn in, triggering a powerful flare that showers the sky with x-rays.

Using NASA’s Chandra X-ray Observatory and other telescopes, a team of astronomers has now pieced together one such astronomical feasting frenzy. The event in question, appropriately named “ASASSN-14li,” was spotted near the center of PGC 043234, a galaxy that lies 290 million light years from Earth.

Has Aging Been Programmed By Evolution?

Posted by in categories: evolution, life extension

Science usually approaches aging from a mechanical viewpoint, but could there be more to the story?

Why do so many scientists now believe that aging has been programmed by evolution?

Science usually approaches aging from a mechanical viewpoint, but the evolutionary theory of aging has gained more support as we observe the wide variation in aging between species.

The dimensional aspect of existence is associated with the dimensions of space and time.

Posted by in categories: cosmology, evolution, information science, materials, neuroscience, particle physics, quantum physics, singularity, space

The dimensionless aspect, since it has no dimensions, is outside of space and time. This is the key aspect to existence: an aspect outside of space and time perpetually interacting dialectically with an aspect inside space and time. All of the weird and wonderful phenomena of the universe are the products of this ultimate dichotomy.

Does this sound crazy? Then consider the evidence provided by black holes.

The R = 0 Universe.
