Two international teams zoned in on a potential answer to a decades-long mystery surrounding ephemeral cosmic X-rays.

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

While the asteroid will remain at a safe distance, scientists are examining potential gravitational interactions that could shift its trajectory. Apophis's close approach highlights the critical ...

Green Gravity’s energy storage system moves heavy weights vertically in legacy mine shafts to capture and release the gravitational potential energy of the weights and is intended to be low-cost ...

In conditions with limited power, such as when constrained by the solar-cell efficiency and/or with reduced solar radiation, it is necessary to efficiently manage the flight energy to ensure ...

The study also delves into the energy dynamics of the collapsing warp drive. The process emits a wave of negative energy matter, followed by alternating positive and negative waves.
