A widely shared experiment claims that gravity can be explained away by density and buoyancy alone. By carefully examining ...

The physical concept of the density-free regime has been verified for the first time on EAST in this work. The EAST experiments combine control of the initial fuel gas pressure with electron cyclotron ...

Each week, we bring you a quick and easy experiment you can do at home to explore a concept in science. This week, we look at ...

For most stars, neutron stars and black holes are their final resting places. When a supergiant star runs out of fuel, it expands and then rapidly collapses on itself. This act creates a neutron ...

High energy density (HED) science seeks to understand and control material at extreme conditions—at temperatures over 20,000°F (approximately 10,000°C, or 10 4 K), pressures millions of times larger ...
