Time Travel: A Quirky Domain of Temporal Mechanics

Posted by in categories: physics, time travel

“I myself believe that there will one day be time travel because when we find that something isn’t forbidden by the over-arching laws of physics we usually eventually find a technological way of doing it.” –David Deutsch

Time travel may still be in the realm of science fiction, inspiring the plots of countless books, mo v ies and Star Trek episodes, but not out of the realm of possibility. While basic physics allows for the possibility of moving through time, certain practical concerns and paradoxes seem to stand in the way. The “Fractal Soliton of Improbability,” postulating that any moment is unique and only happens once in the lifetime of a universe, or “Grandfather Paradox,” in which a traveler jumps back in time, kills his grandfather and therefore prevents his own existence, are the most salient paradoxes arising in relation to time travel.

‘Wonderful news to wake up to’: U.K. greenlights Pfizer’s COVID-19 vaccine

Posted by in categories: biotech/medical, health

MHRA will only become fully independent on 1 January 2021, following Brexit, but U.K. regulations allow it to grant authorizations on an emergency basis. The United Kingdom has bought 40 million doses of the Pfizer/BioNTech vaccine—enough for 20 million people—and health secretary Matt Hancock today announced the first 800,000 doses will be available next week. The rollout will prioritize health workers as well as the elderly and other vulnerable populations, but the Joint Committee on Vaccination and Immunisation has yet to offer its final guidance on the exact priorities.

Russia on 11 August allowed its COVID-19 vaccine, developed by the Gamaleya Research Institute of Epidemiology and Microbiology, to be used on certain groups of people, and China has granted emergency use authorizations (EUAs) for several vaccines and has already vaccinated hundreds of thousands of people with them. A few other countries, including the United Arab Emirates and Bahrain, have issued an EUA for one of the Chinese vaccines, produced by Sinopharm.

The Pfizer vaccine, whose key ingredient is messenger RNA that encodes the spike protein of the pandemic coronavirus, was found to have 95% efficacy, a clinical trial measurement of effectiveness, in a phase III trial in 43,000 people. But it presents logistical challenges for a widescale and rapid rollout, as it requires storage at −70°C. The lesser demands of other vaccines—including a candidate developed by the University of Oxford and AstraZeneca—mean they will likely still play an important role in providing vaccinations for the whole U.K. population—and for global coverage, according to Michael Head, a global health researcher at the University of Southampton, “but, for now, this is wonderful news to wake up to.”

Engineers combine light and sound to see underwater

Posted by in categories: biological, drones, military

Stanford University engineers have developed an airborne method for imaging underwater objects by combining light and sound to break through the seemingly impassable barrier at the interface of air and water.

The researchers envision their hybrid optical-acoustic system one day being used to conduct drone-based biological marine surveys from the air, carry out large-scale aerial searches of sunken ships and planes, and map the ocean depths with a similar speed and level of detail as Earth’s landscapes. Their “Photoacoustic Airborne Sonar System” is detailed in a recent study published in the journal IEEE Access.

SpaceX Starship high-altitude test has one in three chance of landing

Posted by in categories: Elon Musk, space travel

SpaceX Starship will fly nine miles into the air later this week according to Elon Musk, who says it has a one in three chance of landing safely.

The massive Starship two-stage-to-orbit heavy lift vehicle has been in development since 2012 and is designed to bring the cost of launch down by being reusable.

In search for dark matter, new fountain design could become wellspring of answers

Posted by in categories: cosmology, particle physics

You can’t see it. You can’t feel it. But the substance scientists refer to as dark matter could account for five times as much “stuff” in the universe as the regular matter that forms everything from trees, trains and the air you breathe, to stars, planets and interstellar dust clouds.

Though scientists see the signature of indirectly in the way large objects orbit one another—particularly how stars swirl around the centers of spiral galaxies—no one knows yet what comprises this substance. One of the candidates is a Z’ boson, a fundamental particle that has been theorized to exist but never detected.

A new proposed experiment could help scientists determine whether Z’ bosons are real, in that way identifying a possible candidate for dark matter. To accomplish this task, researchers from the National Institute of Standards and Technology (NIST), the University of Groningen in the Netherlands, the Canadian particle accelerator center TRIUMF and other collaborators are working to make the most to date of a nuclear property that is extremely difficult to measure, called nuclear spin-dependent parity violation (NSD-PV).
