Understanding why sound waves travel faster along earth's axis in the inner core New calculations of iron's elasticity at the temperatures and pressures of Earth's inner core show that the directional dependence of sound waves in the crystals is larger than expected....
The Earth is moving faster than it ever has in the last 50 years, scientists have discovered, and experts believe that 2021 is going to be the shortest year in decades. ... This is becausethe Earth is spinning faster on its axis quicker than it has done in decadesand the days are the...
Previous research had shown that the Earth's core rotates faster than the rest of the planet. However, scientists from the University of Cambridge have discovered that earlier estimates of 1 degree every year were inaccurate and that the core is actually moving much slower than previously believed...
That is, according to a new study, which claims that Earth's tectonic plates are moving faster now than at any other point in the last two billion years.Nature World News
It's happening faster now. 现在这一切发生的速度更快了。 And we really need to realize this because those countries have to act, 我们必须意识到这一点, 因为那些国家需要开始行动, including suites of policies like moving away from informal economies that increase the risk of poverty in older ages...

which should remove debris in orbit around the Earth. The plan is to match the target satellite's orbital plane of 630–750km and grasp it, and stabilize it while moving at 28,000km/h. Once nanosatellites have captured their target, both of them will head out of orbit and move toward...
Support for Zelensky, who succumbed to Western pressure by turning away from a possible early negotiated settlement and promising victory and the return of all Ukrainian land, including even Crimea, has dropped off even faster. Once lionized as a war leader and enjoying approval ratings in the ...
But in my opinion the picture that we will assist will be one of a relatively faster recovery phase (about five to six years) after which many things will happen in the geopolitics and socioeconomic order. But, how about to look at this pandemic as a disruptive innovation itself, which ...
The position of the satellite is determined by the balance between gravity potential (as a function of position) and the inertial acceleration of the moving satellite (as a function of time) and is quantified by equations of motion. If positions of the satellite are tracked, a solution for ...
