Are we simulated beings living in a simulated universe?

Posted by in categories: computing, entertainment

Considering how far technology has come in recent years, the idea that we may all just be simulated beings in a simulated game may not be too far off. And microchips might soon become so powerful they can simulate something as complex as the cosmos.

These powerful blazars are the most distant ever seen

Posted by in category: cosmology

Monster black holes shooting jets of gamma-ray radiation right at us have been spotted farther away than ever before, dating back to when the universe was nearly one-tenth its current age.

The five distant objects, called gamma-ray blazars, deepen the mystery of how black holes so large could have formed so early in the universe’s history.

Roopesh Ojha, an astronomer at NASA’s Goddard Space Flight Center in Maryland, presented the new results during a press conference today (Jan. 30) at the American Physical Society meeting in Washington, D.C. The results will also be published in The Astrophysical Journal Supplement. [Found: Gamma-Ray Blazars Powered by ‘Supersized’ Black Holes (Video)].

Help Me, Obi-Wan! New Hologram Technology Mimics ‘Star Wars’

Posted by in categories: augmented reality, holograms, physics

Princess Leia’s holographic plea in the classic film “Star Wars” inspired researchers to work toward a device that could project real-life sci-fi holograms. Now, the futuristic 3D imaging may be one step closer to reality.

A team of physicists at the Australian National University (ANU) invented a tiny device that creates the highest-quality holographic images ever achieved, the scientists said.

Study lead researcher Lei Wang, a Ph.D. student at the ANU Research School of Physics and Engineering, said he first learned about the concept of holographic imaging from the “Star Wars” movies. However, these futuristic-looking 3D images could be used for more practical ends than sending messages from a galaxy far, far away.

Earth And Moon May Be On Long-Term Collision Course

Posted by in categories: energy, evolution, space

Nothing to fret about, but it is interesting that our Earth and Moon may end up colliding in the end. That’s long after our Sun has expanded as a Red Giant, but the implications for other earth-moon type systems are interesting.

For now, our anomalously large Moon is spinning away from us at a variable rate of 3.8 centimeters per year. But, in fact, the Earth and Moon may be on a very long-term collision course — one that incredibly some 65 billion years from now, could result in a catastrophic lunar inspiral.

“The final end-state of tidal evolution in the Earth-Moon system will indeed be the inspiral of the Moon and its subsequent collision and accretion onto Earth,” Jason Barnes, a planetary scientist at the University of Idaho, told me.

A New Alliance Could Give Humanity the World’s First Cancer Vaccine

Posted by in categories: biotech/medical, genetics

The Parker Institute for Cancer Immunotherapy has partnered with dozens of organizations to develop a cancer vaccine to prevent the disease which is expected to grow by an additional 21.7 million through 2030. The plan is to target genetic markers specific to tumors to allow the body to generate an immune response to combat the cancer before it ever takes hold.

Soft robotic sleeve developed to aid failing hearts

An international team of scientists has developed a soft robotic sleeve that can be implanted on the external surface of the heart to restore blood circulation in pigs (and possibly humans in the future) whose hearts have stopped beating.

The device is a silicone-based system with two layers of actuators: one that squeezes circumferentially and one that squeezes diagonally, both designed to mimic the movement of healthy hearts when they beat.

Milky Way galaxy is being pushed across the universe

Posted by in category: space

Our home galaxy, the Milky Way, is being pushed across the universe by a large unseen force, according to new research. Although it may not seem like a friendly gesture, the newly discovered Dipole Repeller is actually helping our galaxy on its journey across the expanding universe.

Researchers have known that the galaxy was moving at a relative speed for the past 30 years, but they didn’t know why.

“Now we find an emptiness in exactly the opposite direction, which provides a ‘push’ in the sense of a lack of pull,” said Brent Tully, one of the study authors and an astronomer at the Institute for Astronomy in Honolulu. “In a tug-of-war, if there are more people at one end, then the flow will be toward them and away from the weaker side.”
