mass bends spacetime, and these bends tell energy how to move.
There is a lot of air resistance and that resistance makes the feather move slower.
... But what keeps the Moon from falling down, if all of this gravity is so strong?
Well ... line into a curve (orbit) around the Earth and ends up revolving around us.
Since gravitational force is present when two objects are sufficiently close, so as
not to ..... This follows Newton's Third Law of motion, which tells us that the total ...
Apr 28, 2016 ... The speed of gravity is taken to be exactly equal to the speed of light. But is that
necessarily true? Here's how we know.
Jun 14, 2012 ... So "a" and "d" are wrong because no gravity means no orbits. "b" is wrong
because there is no force to move the sun closer to the earth.
The Sun's gravity pulls on the planets, just as Earth's gravity pulls down anything

Jan 15, 2014 ... So for the Sun and the Earth, the incredibly large mass of the Sun ... In Einstein's
theory of gravity, these ripples move at the speed of light, not ... aimed at us, we
can test whether gravity moves at the speed of light or not!
But the Sun's force of gravity out here, by us, is far too weak to measure this effect
... theory of gravity are incredibly sensitive to the speed of light, so much so that ...
