A new report offers the latest confirmation of 3I/ATLAS and its interstellar origins, as scientists still debate over its unusual properties.

Using algorithmic techniques and mathematical models, researchers were able to interpret gravitational signals from both mergers ... If they exist, ultralight bosons could extract rotational energy ...

For the first time, scientists have detected two black hole mergers with spins so unusual they may reveal a new generation of ...

Two recently observed black hole mergers, occurring just weeks apart in late 2024, have opened an extraordinary new window ...

New strategies may soon allow scientists to test dark energy theories within our own solar system, linking cosmic-scale physics to local observation. Science advances through a cycle of proposing ...

Japanese physicists have revived Kelvin’s old idea of cosmic knots, showing how these tangled fields might explain why matter ...

In a paper published in The Astrophysical Journal Letters, the international LIGO-Virgo-KAGRA Collaboration reports on the detection of two gravitational wave events in October and November of 2024 ...

These knots, made of tangled energy fields, may have briefly dominated the cosmos after the Big Bang and helped create the ...

NANJING — In the eastern Chinese coastal county of Rudong, Jiangsu province, a 35-storey-high steel structure houses around 1,000 25-metric-ton gravity blocks that are lifted to store surplus ...

In January 2025, a ripple in spacetime reached Earth from more than a billion light-years away. It wasn’t light or radio ...

In 1867, Lord Kelvin imagined atoms as knots in the aether. The idea was soon disproven. Atoms turned out to be something ...

Most explanations rely on "dark energy" to explain the Universe's accelerating expansion rate, but a new study takes a different path.
