In 1915, Albert Einstein figured out the answer when he published his theory of general relativity. The reason gravity pulls you toward the ground is that all objects with mass, like our Earth, actually bend and
Gravity is a force that attracts two objects. Many people think of Sir Isaac Newton and how he watched an apple fall from a tree when we think of gravity. Gravity does not just relate to falling objects, but is also a force that pulls and keeps objects where they belong....
Is the strong nuclear force stronger than gravity? Define weak nuclear force How strong is electromagnetic force? What causes the strong nuclear force? What is threshold energy in nuclear physics? Is there an equation for the weak nuclear force? What is nuclear force of attraction? Why does the...
*Shocking historical claims of government secrecy and hidden research* *The TRUTH behind so-called "anti-gravity devices" and why they're not what they seem* *Mind-bending physics concepts like negative energy, the Casimir Effect, and black holes* *Could a unified field theory be the key to...
This occurs as a result of the planet's gravity, and also because of the effects of its magnetic field. Now, if material from Saturn's rings is being lost and nothing new is added from time to time, the rings would be disappearing. But that's not happening! So somehow, there must ...
Gravity constantly pulls things down when it enters the earth’s atmosphere. Why does earth have a gravitational pull? Earth’s have a gravitational pull that keeps us on the ground so we won’t float off in space. What is the earth’s atmosphere made of? earth’s atmosphere has 78% ox...

Another way that doctors can detect dehydration from your urine comes from a specific gravity test. This test compares your urine’s density to that of water. It can provide helpful clues about how well your kidneys are filtering, and can also indicate both dehydration and over-hydration. ...
The blank gets lowered into a graphite furnace (3,452 to 3,992 degrees Fahrenheit or 1,900 to 2,200 degrees Celsius) and the tip gets melted until a molten glob falls down by gravity. As it drops, it cools and forms a thread. The operator threads the strand through a series of coat...
You may not be lifting a weight, but you’re carrying your own weight up an incline against the force of gravity—its own kind of resistance training. Speed workouts will also engage fast-twitch muscle fibers. “If you’ve been doing nothing but easy effort, marathon-pace runs, ...
