Theory claims to offer the first ‘evidence’ our Universe is a hologram

While theories of holographic universes have been around since the 1990s, the latest study, published in the journal Physical Review Letters, contains the first proof, the researchers say.
To find the ‘evidence’, the researchers developed models of the holographic Universe that can be tested by peering back in time as far as 13 billion years, at the furthest reaches of the observable Universe. These models depend on the theory of quantum gravity, a theory that challenges the accepted version of classical gravity. The holographic principle says gravity comes from thin, vibrating strings which are all holograms of a flat, 2D Universe.

Europe’s fastest supercomputer is now connected to a quantum computer
Posted by Kelvin Dafiaghor in categories: quantum physics, supercomputing
A quantum computer has been connected to Europe’s fastest supercomputer. It may be a step towards a new type of computing that combines traditional and quantum computers to quickly solve complex problems.
The promise of quantum computers is that they will eventually complete calculations that are impossible for the most powerful conventional computers. Though many researchers are working on perfecting quantum computers, many are also suggesting that existing, imperfect quantum computers could be more useful if connected to traditional supercomputers.

Physicists Say New Breakthrough Proves Fusion Power Is Possible
Posted by Kelvin Dafiaghor in categories: nuclear energy, physics
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.

Becoming a Kardashev Type I Civilization
Posted by Dan Breeden in categories: energy, media & arts, space, sustainability
The Kardashev Scale has become a standardized way of classifying (hypothetical) advanced civilizations. The lowest rank, Type 1, is still way ahead of us — but by how much? When will we achieve Type 1 status and exactly how could we plausibly do so? In this video, we go through some estimates of when humanity might become Type 1, and in particular what kind of energy sources we could harness to achieve this feat.
You can now support our research program and the Cool Worlds Lab at Columbia University: https://www.coolworldslab.com/support.

Traveling Back in Time
Posted by Dan Breeden in categories: cosmology, education, media & arts, physics, space travel, time travel
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.
An educational video written and presented by Professor David Kipping.

US Air Force successfully tests first full prototype of its hypersonic missile
Posted by Gemechu Taye in category: military
It reached speeds greater than Mach 5, maybe even Mach 20.
The U.S. Air Force has successfully completed the test of its full prototype operational hypersonic missile at the Elgin Air Force Base off the Southern California coast on December 9, a press release said. The hypersonic missile, dubbed Air-launched Rapid Response Weapon (ARRW), met all objectives of the test flight.
Designed and developed by Lockheed Martin, ARRW, an air-to-ground missile, is a boost-glide vehicle that can strike “fixed, high-value and time-sensitive targets”, as per the press release. The missile can be carried under the wing of an aircraft such as the B-52 bomber.

A Dutch startup uses Bitcoin mining to grow tulips in the Netherlands
Posted by Gemechu Taye in categories: bitcoin, climatology, cryptocurrencies, sustainability
A Dutch entrepreneur is helping to fight climate change rather unexpectedly — by using cryptocurrency mining to grow tulips!
In a modern twist, the Dutch are using bitcoin mining to reap an age-old bounty — tulips! Known for centuries as one of their most iconic cash crops, these beloved flowers now have another purpose in Holland: powering cryptocurrency.
The idea is so promising that even philosopher Nassim Nicholas Taleb has compared bitcoin mining in greenhouses to his concept of the “black swan” event. Despite the comparisons to Tulipmania, Koning believes that Dutch agriculturalists could benefit greatly from bitcoin mining in the years ahead.

A Scottish company wants to make rocket fuel from unrecyclable plastic waste
Posted by Gemechu Taye in category: space travel
It could reduce fuel costs by a fifth and pollution.
Edinburgh-based Skyrora is a company aiming for many firsts. It wants to be the first company to accomplish an orbital launch from U.K. soil but is likely to end up being known as the first company that converts unrecyclable waste plastic into rocket fuel.
With the recent completion of the Artemis I mission, humanity is well on its way to setting up a settlement on the Moon and now has Mars in its sights. As our goals become more ambitious, we also need larger rockets that can take us to faraway destinations. However, rocket launches require tons of fuel and produce larger amounts of carbon emissions.
