As we all know,the earthquake is inevitable,but we can take some methods to reduce it.First,when the earthquake happen we should hide under the furniture which are very solid(坚固的).Second,we should keep calm,and dont worry about it.Third,we should make sure that the door is open so ...
Gravity is a force that we experience every day, yet it remains somewhat of a mystery. It's the reason we stay grounded on Earth and why objects fall when dropped. Although there are several theories attempting to explain gravity, scientists still don't completely understand it. In this arti...
Setting up a lunar time zone is not easy.Gravity affects how quickly or slowly time passes.Since gravity is weaker on the Moon than it is on Earth,after 24 hours,a lunar clock would be 56 microseconds ahead of a clock on Earth.Another point to consider is that a ...
While there were doubtless plenty of people in the 1960s who doubted that humans were capable of reaching the moon, the moon landing conspiracy theory as it exists today was started by one man named William Kaysing. Born in 1922 in Chicago, Kaysing served in the U.S. Navy during WWII a...
This movement of air over the surface of the wing generates lift, the force that counters gravity and keeps the glider aloft. Once aloft, gravity (the weight of the hang glider and pilot) pulls the glider back toward Earth and propels the glider forward, continually causing air to flow ...
Scientists analyze whether plants can properly grow with lower levels of gravity, and just what those levels are. Artificial Lighting Most plants on Earth have access to loads of natural sunlight and grow toward that light, but researchers must fool plants growing in space to follow this same ...
we humans are both blessed and cursed by the force of Earth’s gravity. On the one hand, it makes getting into space rather difficult and expensive. On the other, it ensures our health, since our species is the product of billions of years of species evolution that took place in a 1g...

Petroleum, also called crude oil, is a naturally occurring liquid found beneath the earth’s surface that can be refined into fuel.
Astronomers know it exists because something in the universe is exerting a significant gravitational pull on things we can see. When they measure the effects of this gravity, scientists estimate that dark matter makes up to 23 percent of the universe. Baryonic matter accounts for just 4.6 percent...
