In the last episode of Cosmos: A Spacetime Odyssey (which you can watch online), the show was trying to make a case for dark matter. Here is what Neil DeGrasse Tyson said about orbiting objects. "In ...

Orbital mechanics can be a bit counter-intuitive. We have to slow down an orbiting space craft to convert kinetic energy for gravitational energy. The orbital altitude is raised at its highest point ...

A new study has challenged a popular explanation for the unexpected 30-second shortening of Dimorphos's orbital period. The ...

A new experiment confirms that angular momentum conservation holds even when a single photon is split into two.

Monopoles of orbital angular momentum (OAM) are a tantalizing prospect for orbitronics because OAM is uniform in all directions. This would mean that information flows could be generated in any ...

Understanding the structure of the wavefunction is essential for depicting the surface states of a topological insulator. Owing to the inherent strong spin–orbit coupling, the conventional hand-waving ...

The moon's period of rotation around the Earth is identical to its rotation about its axis. What are the odds of this happening by chance, or are there physics behind this occurrence? originally ...

IVO Quantum drive seems to be showing a reduced orbital decay. Around October 1, 2025, the rate of orbital decay has slowed.

Super Planet Crash is a pretty simple game: players build their own planetary system, putting planets into orbit around a star and racking up points until they add a planet that destabilizes the whole ...
