Simulations and supercomputing calculate one million orbits in cislunar space
Satellites and spacecraft in the vast region between the earth and moon and just beyond — called cislunar space — are crucial for space exploration, scientific advancement and national security. But figuring out where exactly to put them into a stable orbit can be a huge, computationally expensive challenge.
In an open-access database and with publicly available code, researchers at Lawrence Livermore National Laboratory (LLNL) have simulated and published one million orbits in cislunar space. The effort, enabled by supercomputing resources at the Laboratory, provides valuable data that can be used to plan missions, predict how small perturbations might change orbits and monitor space traffic.
To begin, the Space Situational Awareness Python package takes in a range of initial conditions for an orbit, like how elliptical and tilted the orbit is and how far it gets from the earth.

Scientists Announce a Real Warp Drive Is Now Possible
Scientists say a real warp drive may no longer be pure science fiction, thanks to new breakthroughs in theoretical physics. Recent studies suggest space itself could be compressed and expanded, allowing faster-than-light travel without breaking known laws of physics. Unlike sci-fi engines, this concept wouldn’t move a ship through space — it would move space around the ship. Researchers are now exploring how energy, gravity, and exotic matter could make this possible. In this video, we explain how a warp drive could work and how close science really is.

Nothing Is Real: The Simulation Hypothesis
Are we living inside a computer simulation? The evidence is more compelling than you think.
In this deep exploration of the Simulation Hypothesis, we examine the scientific and philosophical arguments that suggest our reality might be code. From Nick Bostrom’s groundbreaking trilemma to quantum mechanics acting like a computer program, from the fine-tuned constants of physics to Elon Musk’s probabilistic arguments—we follow the evidence wherever it leads. Whether we’re simulated or not, the question reveals profound truths about consciousness, reality, and what it means to be human.

The Mystery of Consciousness: Antonio Damasio & David Chalmers with Marcelo Gleiser
A neuroscientist, a philosopher and a physicist convene to discuss one of the biggest and most significant questions of all time: human consciousness, what we know and don’t know about it, and whether science will ever be able to understand what makes you, you.

CATL unveils battery with 12-minute charging and 1.5 million mile life
The company is already the world’s largest battery maker, supplying cells to major automakers. With this latest development, the battery giant is positioning itself at the center of the race to deliver gasoline-like convenience without sacrificing durability.
The core challenge engineers set out to address was whether an EV battery could withstand repeated ultra-fast charging without rapid degradation. A 5C charge rate means an 80-kilowatt-hour battery pack could theoretically accept around 400 kilowatts of power. That level of charging can refill a battery in roughly 12 minutes, similar to a typical gas stop.
Fast charging has long been associated with faster wear. The engineers tested whether the chemistry could handle that stress over time. According to the company, the answer was yes. Under standard conditions at 68°F, the battery retained at least 80 percent of its original capacity after 3,000 full charge-and-discharge cycles.
