Physicists recreated the first millisecond after the Big Bang — and found it was surprisingly soupy
Scientists saw a quark plowing through primordial plasma for the first time, offering a rare look at the first moments after ...
A new study led by the University of Florida has revealed that one of the planet’s most significant "gravity holes" sits directly beneath Antarctica.
For a long time, scientists knew of a “gravity hole” beneath Antarctica—an area with particularly weak gravitational force. Considering the various threats currently faced by the region, scientists ...
Forte and colleagues now believe Antarctica’s gravity hole was weaker before eventually intensifying around 30 to 50 million ...
A $2 million federal funding boost will help Case Western Reserve University and NASA Glenn Research Center dig deeper into what happens when gravity all but disappears. The funding, included in the ...
“For the last 20 years, people believed that the cosmological constant is positive, and the universe will expand forever,” says Tye, a professor emeritus at Cornell. A positive constant acts like a ...
The Science of Velocity and the Barrier of Entry Aerodynamic wheels are characterized by their “deep-section” rims, which typically range from 40mm to over 80mm in depth. Unlike traditional shallow ...
Hypothetical dark matter stars known as "boson stars" could leave telltale ripples across the cosmos, offering researchers a new way to probe the invisible forces shaping the universe. In 2019, a ...

Is gravity a force or spacetime curvature?
A clear look at how physics defines gravity, from Newton’s force-based model to Einstein’s view of curved spacetime, and why the distinction matters in modern science.
A scandal involving allegedly enlarged ski suits ahead of this year’s Winter Olympics has highlighted the intriguing physics ...
