Because Superman is under holding the Earth since the dawn of time. Now because of the obesity rate going up, Superman will become tired and drop the Earth down all the way to ....HELL!!!!
For simplicity purposes ( which I think are definitely needed here ) let's say that up and down only exist on Earth ( In real life that's not true but for now it is), you understand me. So if you were in a big wonderful spaceships - that they always show in movies and you - jumped ( i.e, you pushed yourleggs from the wall in a springing manner ) you wouldn't fall back where you came form ( notice how I'm not using "down" ) you would keep going up until you hit something.
If we didn't live on planets this would be so much easier. So the question you are asking implies that there is a universal constant ( something that stays the same throughout the universe ) which there isn't. Since your questions implies a universal constant this would be like asking "Why don't people oint he other side of the world fall off?" see where I'm going.
What you define as down is the centre of the Earth because that's where gravity pulls us towards to. To you that must be like "WHAT WERE NOT BEING PULLED TOWARDS THE CENTRE OF THE EARTH, WE JUST FALL DOWN!!!!" but no that is an ignorant and quite embarrassing mindset ( chances are if you went to a school you just weren't paying attention, and now you are being viewed as an idiot on the internet ). The reason it seems like we are being pulled downwards and not in a sphere ( the shape of the earth ) is because the Earth is so big it feels like it's flat ;). Hopefully that answered your question.
If there was a "down" for Earth it would be the space-time curvature depicted by Earth hovering over a sink-hole looking grid graphic representing relativity and how it pertains to the idea of gravity. Why don't galaxies and such collide into each other? Pulling themselves towards each other. Big bang, distance, momentum, scale, some do pull themselves towards each other and combine. There is nothing to fall into, it's just empty space.
Nothing moves in a direction based on "up" or "down". We move towards earth due to gravity. Earth is influenced by the gravity of the sun. But earth also have a centripetal velocity that maintains it at a particular distance from the sun. The earth can escape sun's gravity if it have higher centripetal velocity (617.5 km/s). Currently, earth is travelling at 30 km/s. Meanwhile, the earth would move towards the sun if the centripetal velocity is slower.

Well....actually if you define gravity as your frame of reference for up and down (against gravity up and with down)
then right now the earth would actually be "jumping" and it should eventually fall down as the entire universe collapses back into one point
He stretcheth out the north over the empty place, and hangeth the earth upon nothing.
Job 26:7 KJV
http://bible.com/1/job.26.7.KJV
God told us that before science was ever invented. The power of God is mightier than the force of gravity.
Nothing falls down in space as there are no ups and down in space. Ups and Downs are only when you are inside the gravitational atmospheric zone.
Actually it does fall,it is the orbit of the Earth
it does, I suppose. It is always falling. more a question of what you choose to define as "down".
What's "down"?
Think carefully, now...
