The laws of physics don’t actually exist, according to this physicist

The laws of physics do not exist, a theoretical physicist named Sankar Das Sarma argues in a new column published by New Scientist. While we define the laws as the “ultimate laws” of our universe, Sarma says they are merely working descriptions, and that they are nothing more than mathematical equations that match with parts of nature.

Molecular shape-shifting: New theory on autonomous remodeling of structures

Structures made out of building blocks can shift their shape and autonomously self-organize to a new configuration. The physicists Saeed Osat and Ramin Golestanian from the Max Planck Institute for Dynamics and Self-Organization (MPI-DS) revealed this mechanism which may be used to actively manipulate molecular organization. A seed of the novel desired configuration is sufficient to trigger reorganization.

This principle can be applied on to biological blocks which are constantly recycled to form new structures in living systems.

The concept of remodeling is familiar to most people: those who have ever played with Lego bricks know that many combinations and structures possible from the same components.

How do wind turbines spin during winter? The science behind frozen blades

Building a wind power operation that can thrive in icy conditions requires a keen understanding of the underlying physics.

Winter is supposed to be the best season for wind power — the winds are more potent, and since air density increases as the temperature drops, more force is pushing on the blades. But winter also comes with a problem: freezing weather.

Frequent severe icing can cut a wind farm’s annual energy production by over 20 percent, costing the industry hundreds of millions.

Even light icing can produce enough surface roughness on wind turbine blades to reduce their aerodynamic efficiency, which reduces the amount of power they can produce, as Texas experienced in February.

The Halo Drive

How could we one day travel between the stars with real physics? Perhaps the greatest challenge to interstellar flight is energetics — it takes vast amounts of energy to accelerate even small ships to 20% the speed of light. But what if we could steal that energy from where? Perhaps even a black hole. Enter the “halo drive”, a video by Prof David Kipping based on his new peer-reviewed research paper on the subject.

Physicists Say New Breakthrough Proves Fusion Power Is Possible

Researchers at the Lawrence Livermore National Laboratory claim to have achieved the seemingly impossible: generate more energy with a fusion reaction than they put into it, potentially paving the way for a truly environmentally friendly and safe source of power.

Their experiment, which involved using the “world’s largest and highest energy laser system” at Livermore’s National Ignition Facility to blast light at small capsules of deuterium-tritium fuel, generated 20 percent more energy than the amount required to power the system.

Despite the modest energy output — the system generated enough power to boil around two to three kettles — the researchers are boldly predicting that it could represent a major turning point in the quest to turn fusion energy into a reality.

Traveling Back in Time

Backwards through time? We travel forwards every day, but traveling back could let us change our past, visit old friends, or manipulate the timeline to our benefit… Although our knowledge of space and time remains incomplete, we can still use what we know to consider possible time machines. But what kind of paradoxes would this entail and how can we resolve them? Join us today on a special journey through time.

Future flying robots could be inspired by the aerodynamics of gliding snakes

A hidden mechanism for achieving glides of hundreds of feet is revealed by computational modelling.

Scientists are currently thinking of ways to create robots resembling the gliding motion of flying snakes, according to a study published today (Dec .13) in Physics of Fluids.

‘Undulations’ encourage lift.

The researchers anticipate their findings will improve our comprehension of gliding motion and result in a more effective design for future airborne snake robots.

A Jupiter-sized spacecraft? Scientists say existing instruments could detect alien technology

“I wouldn’t want to be on the team figuring out how to build a Jupiter-sized spacecraft, but the odds aren’t zero.”

A team of scientists believes we may be able to detect alien spacecraft flying through distant solar systems using the Laser Interferometer Gravitational-Wave Observatory (LIGO) in the US.

Though the scientists from Applied Physics, a research institute in New York, concede that gravitational wave (GW) detection is “in its infancy”, they also say it is “a sophisticated science” that could be used to “detect extra-terrestrial mega-technology,” in a paper available in pre-print server arXiv.
