Can we understand the universe? | Sheldrake & Hossenfelder go head to head on dark matter IN FULL

Sabine Hossenfelder, Rupert Sheldrake and Bjorn Ekeberg go head to head on consciousness, panpsychism, physics and dard matter.

“Not only is the universe stranger than we think. It is stranger than we can think.” So argued Niels Bohr, one of the founders of quantum theory. We imagine our theories uncover how things are but, from quantum particles to dark matter, at fundamental levels the closer we get to what we imagine to be reality the stranger and more incomprehensible it appears to become.

Might science, and philosophy one day stretch to meet the universe’s strangeness? Or is the universe not so strange after all? Or should we give up the idea that we can uncover the essential character of the world, and with Bohr conclude that the strangeness of the universe and the quantum world transcend the limits of the human mind?

Mysterious New Warp Drive Patent Surfaces Online

😗😁 2021

After appearing for decades in science fiction, then moving into an actual theory, a new patent for an updated warp drive was published last year to no fanfare. Like many other false starts in cutting-edge research, the patent may represent the next step in the expanding theory, or it could mean the practical, real-world design of a functioning warp drive is on the horizon.

Background: How to Bend Space-Time with A Warp Drive

After first publishing his groundbreaking 1994 warp drive concept in the journal Classical and Quantum Gravity, Mexican Mathematician and Physicist Miguel Alcubierre received significant positive and negative feedback. Most applauded his solution, which did indeed appear to create a working theory on how a warp drive might allow faster than light travel without violating the laws of physics. In contrast, others zeroed in on the incredible amount of energy needed to propel his theoretical spacecraft.

Superconducting Optomechanical Breakthrough: A Quantum Leap in Mechanical Oscillator Technology

Scientists at EPFL have developed a superconducting circuit optomechanical platform that demonstrates ultra-low quantum decoherence and high-fidelity quantum control. Their groundbreaking work with a “vacuum-gap drumhead capacitor” has led to the longest quantum state lifetime in a mechanical oscillator ever achieved, paving the way for new applications in quantum computing.

Performing computation using quantum-mechanical phenomena such as superposition and entanglement.

“Quantum Avalanche” — A Phenomenon That May Revolutionize Microelectronics and Supercomputing

New Study Solves Mystery on Insulator-to-Metal Transition

A study explored insulator-to-metal transitions, uncovering discrepancies in the traditional Landau-Zener formula and offering new insights into resistive switching. By using computer simulations, the research highlights the quantum mechanics involved and suggests that electronic and thermal switching can arise simultaneously, with potential applications in microelectronics and neuromorphic computing.

Looking only at their subatomic particles, most materials can be placed into one of two categories.

A quantum leap in mechanical oscillator technology

Over the past decade, scientists have made tremendous progress in generating quantum phenomena in mechanical systems. What seemed impossible only fifteen years ago has now become a reality, as researchers successfully create quantum states in macroscopic mechanical objects.

By coupling these mechanical oscillators to light photons—known as “optomechanical systems”—scientists have been able to cool them down to their lowest energy level close to the , “squeeze them” to reduce their vibrations even further, and entangle them with each other. These advancements have opened up new opportunities in , compact storage in quantum computing, fundamental tests of quantum gravity, and even in the search for dark matter.

In order to efficiently operate optomechanical systems in the quantum regime, scientists face a dilemma. On one hand, the mechanical oscillators must be properly isolated from their environment to minimize ; on the other hand, they must be well-coupled to other such as electromagnetic resonators to control them.

Quantum computing could give AI the rocket fuel to be transformative

Quantum computing could give us machines massively more powerful than today’s, but we still have a long way to go, say leaders in the field.

The tech story of the century so far has been the mainstream arrival of generative artificial intelligence, which drives the uncanny capabilities of systems such as ChatGPT, and is fast being absorbed into our everyday lives.

Whether to mimic human creativity, double as empathetic counsellor or eliminate clerical drudgery, generative AI has delivered an unprecedented surge in excitement for its potential benefits.

Of equal concern are possible negatives: catastrophic job losses, widespread disinformation, and even – at the wildly unsettling end of the… More.

Quantum computing will change the world as we know it, but more breakthroughs are needed before we see the hugely powerful processors become an everyday reality, say quantum physicists.

Sandia shows quantum breakthrough promise with new ion trap

Sandia’s 20 year experience in building and testing ion traps has culminated in its latest offering: the Enchilada Trap.

Sandia National Laboratories revealed the Enchilada Trap, a groundbreaking ion trap central to some quantum computers, in a press release.

This innovative device promises to reshape the landscape of quantum computing, providing researchers with a potent tool to explore the experimental and transformative field of quantum computation.

Can an ancient board game solve quantum problems?

The central problem quantum state engineering is trying to solve, says Ryan Glasser is “what do I need to do to get my quantum system to be in the state I desire?” Researchers hope ManQala, a version of the ancient game mancala, has answers. (Credit: Tobias Tullius/Unsplash)

The game mancala may have originated as far back as 6,000 BCE in Jordan and is played around the world to this day. It consists of stones that players move between a series of small pits on a wooden game board. The point of the game is to get all the stones into the last pit at the end of the board.

Is Quantum Mechanics a Science? Here’s What Karl Popper Thinks

The crisis of understanding, according to Popper, arose in physics along with the Copenhagen interpretation, or, more precisely, from the point of view of Bohr and Heisenberg on the status of quantum mechanics.

In his opinion, quantum mechanics should be interpreted as the last revolution in physics, since the inherent boundaries of knowledge were reached in it.
