Remember... All we're offering is the truth.
Space, not just the world we all live in, but all
the space in the universe is "affected" by MASS
(massive objects) in a way that most people do not
realize. Most people think that gravity has
something to do with a "magnetic" force of some kind
that causes objects to be attracted to other
objects. The weird truth of it is that "gravity" is
a side-effect of the "geometry" of space-time.
What does that mean? What Einstein figured out is
that SPACE is actually "warped" or "curved" by mass
(or massive objects) like the Sun or planets, or
black holes - that sort of thing. Now while you
cannot really SEE this,
you can see the "effect" of it. When an asteroid
passes closely by a massive object, it may be
affected by the objects gravity and drawn toward it.
But this has nothing to do with magnetism - it is
actually the effect of the asteroid following the
"curvature of space" (since the massive object -
like the Sun - has warped space).
To think of a common, simple example: imagine a
BOWLING BALL sitting on a large rubber sheet (or
your mattress).... you will notice that the massive
ball makes an big depression in the sheet, or "dip"
in your mattress. Now imagine rolling a marble
across this sheet, or your mattress. If it is close
enough to the bowling ball, it will be "captured by
the gravity" (really warped space) and spiral inward
toward the bowling ball. So "Curved Space" is the
"warping of space" caused by "massive objects", and
what we see as gravity is really just objects
responding to the natural curvature of space.
Many people then ask why an apple falls straight to
the ground on earth. The general idea is that space
is "more steeply curved" when close to massive
objects (as we are standing on earth) and since we
are already ALWAYS in motion (you knew that - with
rotation and all), when you "let go" of a ball, it
travels eastward (with you) and follows a path of least resistance in curved
space, which is a parabolic curve towards the
ground. Since you are also traveling east,
with the ball, it appears from your perspective to
"fall" straight down to the ground.
