Europa's gravity is approximately 13% of Earth's. The temperature on Europa varies from −160 °C at the equator, to −220 °C at either of its poles. [145] Europa's subsurface ocean is thought to be significantly [clarification needed] warmer however. It is hypothesized that because of radioactive and tidal heating (as mentioned in the ...
Several days later, Terry was playing the guitar in their home. The sphere seemed to react to the sound of the guitar. It made a throbbing noise. Later, the sphere was noticed to roll on its own and even stop on its own and change direction. Terry started doing experiments with the sphere. He noticed the sphere would reverberate when hit with a ...
The mass of such a cylinder is itself greater than 9 short tons (8.2 t), so the practical applications of such a system are limited to those situations where its other characteristics provide a clear and decisive advantage—a conventional bomb/warhead of similar weight to the tungsten rod, delivered by conventional means, provides similar ...
Europa Clipper (previously known as Europa Multiple Flyby Mission) is a space probe developed by NASA to study Europa, a Galilean moon of Jupiter. It was launched on October 14, 2024. [ 15 ] The spacecraft will use gravity assists from Mars on March 1, 2025, [ 10 ] and Earth on December 3, 2026, [ 11 ] before arriving at Europa in April 2030 ...
The reddish-brown color of the markings is theorized to be caused by sulfur, but because no data collection devices have been sent to Europa, scientists cannot yet confirm this. [39] Europa is primarily made of silicate rock and likely has an iron core. It has a tenuous atmosphere composed primarily of oxygen. [40]
Vast Space is a private company that proposes to build the world's first artificial gravity space station using the rotating spacecraft concept. [23] A Mars gravity simulator could be built on the Moon to prepare for Mars missions. The surface gravity of Mars is somewhat more than twice that of the Moon.

This is the point at which it has been hypothesized that the known laws of gravity cease to be valid. [11] There are competing theories as to what occurs at this point. For example loop quantum gravity predicts that a Planck star would form. Regardless, it is argued that gravitational collapse ceases at that stage and a singularity, therefore ...
