New Form Of Atomic Nuclei Just Confirmed, And it Suggests Time Travel is Impossible
Posted by Phillipe Bojorquez in categories: physics, time travel
A group of scientists confirmed that there is a pear-shaped nucleus. Not only does this violate some laws in physics, but also suggests that time travel is not possible.
A new form of atomic nuclei has been confirmed by scientists in a recent study published in the journal Physical Review Letters. The pear-shaped, asymmetrical nuclei, first observed in 2013 by researchers from CERN in the isotope Radium-224, is also present in the isotope Barium-144.
This is a monumental importance because most fundamental theories in physics are based on symmetry. This recent confirmation shows that it is possible to have a nuclei that has more mass on one side than the other. “This violates the theory of mirror symmetry and relates to the violation shown in the distribution of matter and antimatter in our Universe,” said Marcus Scheck of University of the West of Scotland, one of the authors of the study.

New Paper Claims EM Drive Works, Produces Light As Exhaust
Posted by Andreas Matt in categories: physics, space travel
A new paper in AIP Advances argues that the controversial EM Drive doesn’t break physics as we know it, as it emits light (photons) as exhaust. However, other experts assert that it’s likely just an artifact.
Want to get people excited about science? Simple. Just post about EM Drive.
For those of you who may be new to the topic, EM Drive is a method of space travel that, if realized, would utterly transform our way of life. We could get to Mars in just 10 weeks (as opposed to the current 6+ month journey), and we could save a massive amount of money on fuel. We could have a truly viable space industry.

The universe is crowded with black holes, astronomers predict
Posted by Andreas Matt in categories: cosmology, physics
A new study published in Nature presents one of the most complete models of matter in the universe and predicts hundreds of massive black hole mergers each year observable with the second generation of gravitational wave detectors.
The model anticipated the massive black holes observed by the Laser Interferometer Gravitational-wave Observatory. The two colliding masses created the first directly detected gravitational waves and confirmed Einstein’s general theory of relativity.
“The universe isn’t the same everywhere,” said Richard O’Shaughnessy, assistant professor in RIT’s School of Mathematical Sciences, and co-author of the study led by Krzysztof Belczynski from Warsaw University. “Some places produce many more binary black holes than others. Our study takes these differences into careful account.”

Science Council to make clear position on lifting military-linked research ban
Posted by Karen Hurst in categories: law, military, physics, science, security
Interesting.
The Science Council of Japan will make clear its position on military-linked research — possibly overturning a decades-long ban — by early next year, the academic group said Friday.
A committee of 15 academics from fields ranging from physics, political science to law held its first meeting to discuss whether to revise statements released by the council in 1950 and 1967 stating that the group will “never engage in military research.”

“Computational Complexity and Fundamental Physics”
Posted by Karen Hurst in categories: physics, space
Sharing in case anyone is interested Prof. Scott Aaronson’s Computational discussion on “Complexity and Fundamental Physics”.
Summer continues, and the public lecture series on physics continues a pace at the Aspen Center for Physics with Dr. Catherine Heymans of the University of Edinburgh talking today on the “Dark Side of the Universe”.
The talk is part of one of the three workshops currently taking place:

Doubled sensitivity could allow gravitational wave detectors to reach deeper into space
Posted by Andreas Matt in categories: cosmology, physics
Researchers from the Massachusetts Institute of Technology (MIT) and Australian National University have developed new technology that aims to make the Advanced Laser Interferometer Gravitational-Wave Observatory (LIGO) even more sensitive to faint ripples in space-time called gravitational waves.
Scientists at Advanced LIGO announced the first-ever observation of gravitational waves earlier this year, a century after Albert Einstein predicted their existence in his general theory of relativity. Studying gravitational waves can reveal important information about cataclysmic astrophysical events involving black holes and neutron stars.
In The Optica l Society’s journal for high impact research, Optica, the researchers report on improvements to what is called a squeezed vacuum source. Although not part of the original Advanced LIGO design, injecting the new squeezed vacuum source into the LIGO detector could help double its sensitivity. This would allow detection of gravitational waves that are far weaker or that originate from farther away than is possible now.
