Instead it predicts that time slows down in a gravitational field, making clocks run a little slower on Earth's surface than in deep space. 与此相反,相对论预测,时间在引力场作用下要放慢,例如,在地球表面运行的时钟略慢于高度深空。 article.yeeyan.org 7. So we conclude that the bending of lig...
As is well known, the earth is mainly a fluid; the upper crust is an exception, but it is extremely thin layer with respect to the earth's radius. For this reason it is natural to expect that rotation around its axis makes the shape of the earth practically the same as if it was ...
"It's not uncommon to think of up and down in space the same way we do on Earth--as movement against or along with a gravitational field." Astronomers also sometimes refer to locations above and below a galaxy, where "above" is in the northern hemisphere and "below" in the southern....

Earth's Gravitational Field refers to the gravitational force surrounding the Earth, which can be modeled using spherical harmonic coefficients based on satellite tracking data.

2. A slow gyration of Earth's axis around the pole of the ecliptic, caused mainly by the gravitational pull of the sun, moon, and other planets on Earth's equatorial bulge. 岁差地球中轴绕黄道极的缓慢旋转,主要由于太阳、月亮和其它星体对地球赤道降起带的重力作用而造成 ...
gravitational field line is an imaginary concept. For any object, the gravitational field lines are always directed radially inward. The gravitational field strength depends on the number of field lines per unit area crossing a surface perpendicular to these lines. As the earth's surface is ...
But one of the most exciting consequences of this research relates not to gravity, but to ordinary, Earth-bound turbulence. From hurricanes to cream stirred into coffee, from the bumblebee's impossible flight to the vortices shearing off the end of airplane wings, turbulence is all around us....
Earth’s gravitational field (indeed, this field extends far into space), but because it is in free-fall towards the Earth. The satellite is constantly falling towards Earth, but its forward motion keeps it in orbit around the planet. This state of free-fall creates the sensation of ...
