The UCLA researchers effectively reproduced the type of gravity that exists on or near stars and other planets inside of a glass sphere measuring 3 centimeters in diameter (about 1.2 inches).

The UCLA researchers effectively reproduced the type of gravity that exists on or near stars and other planets inside of a glass sphere measuring 3 centimeters in diameter (about 1.2 inches).

Koulakis' team filled a rotating glass sphere 1.2 inches (3 centimeters) across with a plasma of sulfur atoms. Microwaves were then employed to heat the plasma to 5,000 degrees Fahrenheit (2,760 ...

If it could be stabilized, a Dyson Sphere built at 93 million miles from the sun, the same distance as the Earth, would contain about 600 million times the surface area of our planet in its interior.

One of them is gravity. If gravity were the only force giving our planet shape, it would be a sphere since gravity is pulling from all directions toward the center. (Photo Credit: KDKA) ...

Gravity is measured between two gold masses that are brought close to each other Physicists have measured the gravitational field of a smaller object than ever before, a gold sphere with a mass of ...
