What keeps the sun and the panets  from falling down?

In earth's atmosphere there is gravity that comes from the core of the earth. In Space, there is no gravity or "Zero Gravity", which means space is does not move except for the obitization of the planets around the sun. But, space is endless, so, we could be falling but never hit because of infinate space. but i do not think we fall.

There are two forces involved to keep a satellite from falling down. First, GRAVITY is constantly trying to pull the satellite down, but at the same time the satellite's speed is trying to hurl it off into space--CENTRIPETAL force. As long as both forces are exactly balanced, the satellite won't fall down.

turn off lights... use a flashlight for sun. see how the opposite side is dark but the front is light.

Stay out of the sun. Suntanning is the worst. That and liquor.

hmmm, good question....\n\nMaybe because it seems to be in a constant state of falling.

for the earth to get closer to the sun, the sun would have to grow or somehow become heavier

Ok you need a bowl of water and the sun. The energy is trapped (at least temporarily) in the water, as heat.

because the sun has gone over the horizon

because the sun is in the middle of setting

The sun is a giant ball of plasma constantly fusing hydrogen into helium.  It is not 'on fire', so to speak, so the lack of oxygen and the coldness of space don't effect it like a match or something.

Clouds are made up of water vapour which rise into the air by the heat of the sun. They stay at a height where the sun has just enough effect to keep them up.

Well...\n\nThe "sun is out" whenever there is a break in the clouds that can let the sunlight in.  You can still have clouds overhead providing precipitation.\n\nAlso, in rare cases, the clouds can drop precipitation and quickly leave while it is still falling to the earth, even though it is not hitting the ground yet.  Remember that precipitation takes a few minutes to travel from the clouds to the ground.\n\nPEACE IS COMMING SOON!

it keeps the population down

you could use the aluminum foil to reflect the sun's rays into the box which you could cover, inside and out, with black paper. that way, it is collecting heat and the color black is the result of every color of light being absorbed and much less light reaching your eyes than something red or blue or another color. so, the black closed space would store the heat gathered by reflecting sunlight into the box\n\nHope this helps, and good luck!

Protect the tar/membrane system from sun/uv, and reflect sun to keep temps lower. Also, weight prevent wind damage to membrane system. Very good roof, long lasting, relatively inexpensive to install.

It absorbs light energy from the sun.

So that they'll not get sun burn.
