Scientists believe that in the very early universe, everything was incredibly tiny, chaotic, and full of random energy ripples, known as quantum foam. It was a state where spacetime was unstable, and ...

Astronomers using the National Science Foundation’s Green Bank Telescope (GBT) have discovered a unique stellar system of two white dwarf stars and a superdense neutron star, all packed within a space ...

Tides on Earth have a far-reaching influence, including disturbing satellites' measurements by affecting their motion. The LAser RElativity Satellite (LARES), is the best ever relevant test particle ...

After turning on in September of 2015, the twin Laser Interferometer Gravitational-wave Observatories -- the LIGO detectors in Hanford, WA and Livingston, LA -- simultaneously detected not just one ...

Exploring Saturn's largest moon, Titan, presents unique orbital challenges due to its dense atmosphere, gravitational perturbations, and limited sunlight. A new study proposes an innovative satellite ...

A region-delimited gravitational wave field can be constructed, such that a subset of geodesics crossing this region will move faster than nearby geodesics moving entirely inside flat spacetime, along ...

Earth's geologic activity, including extinctions, may follow a 26-million-year cycle. This cycle could be caused by comet showers resulting from the Sun's passage through the Milky Way's plane. The ...

Saturn’s C ring is home to a surprisingly rich array of structures and textures. Much of the structure seen in the outer portions of Saturn’s rings is the result of gravitational perturbations on ring ...

Noncommutative quantum mechanics extends the conventional framework by introducing noncommuting spatial (and sometimes momentum) coordinates, thereby altering the standard uncertainty relations and ...
