Why does gravity pull us down and not up? Gravity is the reason things with mass or energy are attracted to each other. It is why apples fall toward the ground and planets orbit stars. Magnets attract some types of metals, but they can also push other magnets away. So how come you fe...
What is time: illusion, constant, dimension or something else? Explain. Why do earth and electrons rotate? From where do they derive energy to rotate? When will they stop rotating? Why does gravity have pull but no push? Why the mesaure of the sphere doesn't play a part at the pendulu...

Why does the photon behave as its own antiparticle?. If dark matter is matter, why is it not affected by gravity? Give a reason why all mesons are formed from a quark and an anti-quark. How is anti matter created? What is a dark matter?
does the entropic state and the greater the time-dilation and as a result the stronger the attraction which is the effect we see as gravity. Due to entropy, matter will “gravitate” to where time is slowest. The curvature of “space-time” is more about time than space as matter is...
There was another important aspect of Einstein's theory which he didn't even realize when he published it. That time was woven into the very fabric of space itself. Einstein used this insight to help develop his general theory of relativity which incorporated gravity. He published it in 1915...
But by solving an old problem, Boeing created a new one. The new engines were too big to fit in their traditional spot under the wings. To combat the problem, Boeing mounted them forward on the wings. Moving the engine position forward shifted the plane’s center of gravity, which altered...
Why Older People Shrink When we say older people shrink, we don't mean they become tiny enough to fit in your pocket. We just mean that it's common for older people to become a little shorter over time. It takes place over years and may add up to only an inch or so off of their...
DWP’s chief executive and chief engineer. She said the hydrants rely on three large water tanks with about 1 million gallons each. Hydrants functioned at lower elevations, but in hillier areas like the Palisades Highlands — where the storage tanks hold water that flows by gravity to communitie...
The brightest visual region may be an overriding cue, but not the only cue for vertical orientation. During slow hovering flights, any mass hanging on the insect’s body (such as legs) can indicate the gravity direction. However, gravity sensing via this method would be challenging during high...
