The mystery of dark matter—unseen, pervasive, and essential in standard cosmology—has loomed over physics for decades. In new ...

For nearly a century, astronomers have watched galaxies spin and the universe expand in ways that visible matter alone cannot ...

The concept of using rotational force to generate artificial gravity for space habitats has been floating around since NASA called it theoretically viable in the 1960s. Now Japanese researchers hope ...

During its initial molten phase, the Moon experienced tidal bulges on its near and far sides due to Earth's immense gravitational pull. The Moon's rotation initially carried these gravitationally ...
