The clock on the equator is moving faster than the one on the pole, so you might expect it to tick slower. However, it has a weaker gravitational potential, so you might expect it to tick faster. It turns out, the effects cancel for non-coincidental reasons and there is no latitude-de...
Humanity is well into the Anthropocene6, the proposed new geological epoch where human pressures have put the Earth system on a trajectory moving rapidly away from the stable Holocene state of the past 12,000 years, which is the only state of the Earth system we have evidence of being abl...
The debris object decays much faster during solar maximum as compared to solar minimum, when the density is lower. The drag acceleration on a satellite at any time is proportional to the mass density of the atmosphere it travels through. As the thermosphere cools and contracts with increasing ...
fastest, while someone standing on the North or South pole would be perfectly still. (Imagine a basketball spinning on your finger. A random point on the ball's equator has farther to go in a single spin as a point near your finger. Thus, the point on the equator is moving faster.) ...
How fast you need to move to keep in a circular orbit around another body is dictated by how far the two bodies are separated from each other. Planets closer to the Sun are orbiting faster than Earth, with Mercury traveling 1.6 times faster than Earth at 105,000mph(47.4km/s). At the...
Urey assumes that the moon was originally an asteroid that, on passing near the earth, became a satellite as a result of the effects of gravity. The probability of such an event is extremely small, and if it happened, there would be a greater difference between earth rocks and lunar rocks...
But by deriving a model for the radial viscosity profile of the Earth that fits both postglacial decay times and free-air gravity anomalies associated with mantle convection, Mitrovica and Forte (1997) found that GIA should cause a secular trend in the LOD amounting to −0.5 ms/cy, a ...
Testing faster-than-light space travel, scientistReed Richards, sister and brotherSueandJohnny Storm, and pilotBen Grimmsneak off into space in a rocket. In space, the four are bombarded by cosmic rays. The autopilot lands the ship back on Earth, where they find themselves physically transformed...
So the planes moving at a constant air speed go faster from the west to the east when they are moving with the wind than in the opposite. 2. What would happen if the gravity on Earth was suddenly turned off? Supposing we could magically turn off gravity. Would buildings and other ...
The new USC study provides unambiguous evidence that the inner core began to decrease its speed around 2010, moving slower than the Earth's surface. The inner core is considered to be reversing and backtracking relative to the planet's surface due to moving slightly slower instead of faster tha...
