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...

Plants exhibit tropisms, tendencies to grow in certain ways based on environmental factors, such as sunlight (phototropism), water (hydrotropism), gravity (gravitropism), chemicals (chemotropism) and even physical contact (thigmotropism). For example, plants tend to bend toward sunlight because sunli...
It boils down togravity. Gravity is the force of attraction between particles of matter. The amount of gravitational force one body exerts on another depends upon the size of the two objects and the distance between them. If there's enough matter in the universe, the force of gravity will ...
Does time slow down near a black hole? What is faster than the speed of light? Does space-time spin? Is gravity faster than the speed of light? Does uniformitarianism apply to the speed of light? Why is time called a paradox?
Does gravity travel at the speed of light? What is the speed of light in air? How far in terms of wavelength does a wave travel in one period? Does time exist at the speed of light? How fast do primary waves travel? Can humans travel at the speed of light?
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...

slightly down. So anything that moves forward in time will find its trajectory pointing down slightly. This takes the form of downward acceleration. This acceleration (time pointing slightly down) is entirely responsible for the motion of the planets, and every other everyday experience of grav...
aircraft — and the seats inside them — must be built to withstand an impact of up to 16G, or g-force up to 16 times the force of gravity. That means, he says, that in most incidents, “it’s possible to survive
