Simmilarly why not the Moon fall on Earth by the Gravity attration?


Why are the planets revolving round the sun for so many years instead

This is a deep question. *It goes right to the heart of why gravity
and space behave the way they do. *As posted above, Newton and
Einstein have given us mathematical models of *how* gravity and space
behave but not *why*. *


Agreed

The only answer that comes to mind is the
anthromorphic principle, which seems to me to be not quite satisfying..


How would an anthromorphic principle helps here?- Hide quoted text -

From Wikipedia "In physics and cosmology, the anthropic principle
states that humans should take into account the constraints that human
existence as observers imposes on the sort of universe that could be
observed. In other words, the only universe we can see is one that
supports life. If it were a different type of universe, we would not
exist to see it."


Mmmmmmmmmmmmmmm

Check what anthromorphic means!

*****I agree that modern science backs you up, but respectfully, that makes

*****There are only two pulls on an orbitting planet: the pull toward the

of the Sun, also one of constant acceleration.

*****If it were any other way, the planet would indeed fall into the Sun.

Hi Mark,

So what is it that is "pulling" in the direction right angles to the
sun?

As others have mentioned (in paraphrase) if you were on the moon and
shot a cannonball parallel to the ground, it would travel for awhile
in that direction, while also falling toward the Moon due to
gravitational acceleration. Eventually it hits the ground.

Now, shoot the cannonball out faster. It goes quite a bit farther
before still eventually falling and hitting the ground.

Shoot it out even faster yet, and it goes so far that even as it
falls, the surface of the round Moon is curving away from it
noticeably. It is only being accelerated (pulled) toward the center
of the Moon, but it has enough starting velocity so that it might
travel all the way to the other side of the Moon before hitting the
ground.

Finally, with an even faster shot, it travels all the way around the
Moon and hits the back of the cannon. Or, if you move the cannon, it
keeps traveling around the Moon, in orbit, still with only its initial
velocity, and the only pull coming from the Moon, toward its center.

Spencer
