All matter in the universe is attracted to all other forms. We give this attraction the name gravity. The greater the matters density the greater the force of attraction it applies to other matter. It does not exist just for huge objects though, you can calculate the force that you have on someone you sit next to on a bench for example, it is just not strong enough to be noticeable. So yes, the planet is falling in a straight line toward the strongest force of attraction which is the sun. Just like the moon is falling in a straight line toward the Earth. If the Earth was stationary the moon would crash into it. However the Earth is always moving, just like the sun is always moving. Also I would say that I explain that an image of a distant galaxy is curved because the force of gravity affects light. That is why it "curves" around planets. The particles within the space are being affected, not the space I think. |
