Gravity, what if, it were weaker?

Question

would cars get better gas mileage? would people have less health prolems? what if,

Answer 1

If it just became weaker, it wouldn't make a large direct difference.  Mainly weather patterns would change dramatically, and we'd start losing our atmosphere.  We'd start drifting away from the sun, receiving less solar energy.  It would solve global warming!

If it started out weaker, galaxies and stars probably never would have formed.  Therefore no planets and probably no life.

Answer 2

Everything would have been developed in other forms of realities.....

The first thing that it crosses my mind is that planet earth will loose its orbit if the gravity was weaker. Then, several senarios are possible. The thing that is certain is that something will be developed (visible or invisible creatures/civilaizations)

Hope it helps

Answer 3

Pretty much every civil engineering question every answered would be wrong, at least it would be conservative :)

Answer 4

We'd all weigh less!

Answer 5

All planets and stars and orbits would have larger radii.
