Gravity 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...
The heavier you are, the steeper the sides of the trampoline well. That is why really massive things in the universe – like the Sun or black holes – have stronger gravity than Earth. So why does gravity pull you down and not push you away? Imagine someone went under the trampoline and...
Newton's original thought experiment describing the parallels between falling and orbiting. The faster an object moves sideways the longer it stays aloft. Fast enough, and it never hits the ground at all. Whether gravity pulls an object into orbit or just “makes it fall” depends on how...
Why is gravity so heavy?GravityGravity or the force due to gravity is defined as the product of the masses of two particles over the distance between then. It is mathematically expressed as {eq}F_g = \frac{Mm}{r^2}{/eq} where {eq}F_g{/eq} is the force due to gravity, {eq}M...
“Switching off” gravity would be like letting go of the string. Things not attached to the Earth would fly off in a straight line. People in buildings would suddenly shoot upwards at a great speed until they hit the ceiling. Most things outside would fly off into space....

“Theoretically, it interacts with gravity, but it has no interaction with the others,weak nuclear force,strong nuclear force, or electromagnetic force,” Sousa said. University of Cincinnati Professor Alexandre Sousa uses a plastic toy to demonstrate how neutrinos change ‘flavor’ as they pass thr...

Galaxies are complex systems held together by gravity. They're made up of gases, stellar dust and millions — sometimes even billions — of stars, which are accompanied by their own planets and asteroid belts. Out of the more than 200 billion galaxies, many have a spiral shape (like the ...
