In this video, we explore the fascinating prospects of humanity becoming a proper interstellar civilization, up to Type III on the Kardashev scale. However, this transition process presents our species with a bunch of physical limitations, as well as societal and even biological implications. Many of them are quite unwanted or even ugly! We explore this vast topic by using the latest scientific models as well as the best science fiction worlds from books, TV shows, and even games. Speaking of which, to help us visualize this space-faring future with much-needed scale and fidelity, we turned to CCP Games — the creators of the massively multiplayer online game EVE Online. https://eve.online/Ridddle_EN. It is set in a rich sci-fi universe, where players can create their own character and explore a vast and complex virtual world built according to the well-thought set of consistent in-world rules The game is known for its intricate economy, politics, and warfare mechanics, where players can engage in a variety of activities, including mining resources, trading, building structures, and participating in battles. Quite frankly, the game feels like a real simulation of all those future endeavors humanity will face on the way to becoming a true interstellar species!

Tapping The Power Of The Stars — Dr. Andrea Kritcher Ph.D., Lawrence Livermore National Laboratory, U.S. Department of Energy.

Dr. Andrea (Annie) Kritcher, Ph.D. is a nuclear engineer and physicist who works at the Lawrence Livermore National Laboratory (https://www.llnl.gov/). She is the design lead of the HYBRID-E capsule technology within Lawrence Livermore’s Inertial Confinement Fusion (ICF) program, and is a member of the ICF leadership team and lead designer for shot N210808, at their National Ignition Facility, a recent experiment that heralded a significant step towards a fusion break-even target. She was elected Fellow of the American Physical Society in 2022.

Russia cannot meet its arms delivery commitments to India because of its ongoing invasion of Ukraine, according to the Indian Air Force (AIF).

The statement, aired during a parliamentary committee meeting earlier this week, was the first official confirmation from New Delhi of Moscow’s defense export shortfalls.

It confirmed speculation that Russia’s defense industry is experiencing serious problems producing military supplies.

Unmanned aerial vehicles (UAVs), also known as drones, can help humans to tackle a variety of real-world problems; for instance, assisting them during military operations and search and rescue missions, delivering packages or exploring environments that are difficult to access. Conventional UAV designs, however, can have some shortcomings that limit their use in particular settings.

For instance, some UAVs might be unable to land on uneven terrains or pass through particularly narrow gaps, while others might consume too much power or only operate for short amounts of time. This makes them difficult to apply to more complex missions that require reliably moving in changing or unfavorable landscapes.

Researchers at Zhejiang University have recently developed a new unmanned, wheeled and hybrid vehicle that can both roll on the ground and fly. This unique system, introduced in a paper pre-published on arXiv, is based on a unicycle design (i.e., a cycling vehicle with a single wheel) and a rotor-assisted turning mechanism.

We had a wonderful group of international and interdisciplinary speakers at Saint Mary’s University on March 31 to April 1, 2017. They all took time out from their very busy schedules to come to Halifax to discuss robots and artificial intelligence at the Cyborg Futures Workshop. Academics from literary theory, digital culture, anthropology, sociology, environmental studies, robotics, and evolutionary biology, along with students and the public, convened for a lively discussion about technologies that are impacting us all.

This workshop is part of a larger SSHRC-funded project–Where Science Meets Fiction: Social Robots and the Ethical Imagination–that is about shifting the conversation about robots and AI, which has been animated by fiction but dominated in the real world by the military and industry. Opening the discussion up to wider social and cultural contexts–from the impact of technology on human relations; to non-human animals, the environment and trash; to racism, imperialism and misogyny; to automation, labour and capitalism; to killer robots and the military; to the problematic collapse of science and fiction—this workshop considered both the infrastructure currently being laid that is forcing us down a troubling path and imaginative alternatives to it. What follows cannot possibly do justice to the richness and complexity of the talks, so please click on the hyperlinks to listen to them.

An explosive material fabricated with a highly porous structure is inactive but is easily “switched on” when filled with water.

Despite great effort, researchers have failed to find ways to make explosives entirely safe during storage yet still easily usable when needed. Now a research team has demonstrated an explosive with these properties by creating a highly porous structure for their explosive material [1]. The voids prevent the structure from supporting a sustained propagating wave of detonation, but filling the voids with water can quickly restore the explosive capacity. The researchers hope this technique can provide safer explosives for use in areas such as mining and oil exploration.

Storing highly explosive materials is inherently risky—in the military world, for example, over 500 accidental explosions occurred at munitions sites between 1979 and 2013, according to a survey [2]. These materials could be safer if they could be easily switched between an explosive-ready state and a “safe” state. “A switchable explosive is the holy grail of explosives research,” says chemist Alexander Mueller of the Los Alamos National Laboratory in New Mexico. He and his colleagues believe that they are the first to achieve it.

Rockets and their engines have long been of interest for both space exploration and military use—including for powering hypersonic weapons.

While the world’s major powers are locked in an arms race to develop the best and most advanced hypersonic weapons, missiles capable of flying faster than Mach 5 and are thus able to defeat missile defense systems and radars, the Defense Advanced Research Projects Agency (DARPA) has been flying at these speeds for more than a decade.

The history of hypersonics go back much, much further than the 21st century. Nazi Germany’s V-2 rockets were able to reach speeds of Mach 4.3 after takeoff, but when they struck targets, they were often exceeding Mach 5. By 1949, the United States had adopted German rocket technology, which allowed rockets to exceed Mach 5 on takeoff for the first time.

Through this development, the U.S. was able to build its intercontinental ballistic missile arsenal, all of which were capable of speeds above Mach 5 upon reentry. It wasn’t until 1980 that hypersonic research began to focus on glide maneuvering and carrying people. This led to the creation of the X-15 rocket plane, a manned craft that could reach those speeds but was launched from a B-52 “mother ship.” An X-15 holds the official world record for the highest speed ever recorded by a crewed, powered aircraft when it reached Mach 6.7 in 1967.

To check that atomic weapons work, scientists run simulations of explosions using high-energy lasers—and Russia is building the strongest one of all.
