Gravitational Force!
I have an interesting question... I am hoping its not to easily answerable because it is early in the morning and i may just not be thinking in the right mind.
Energy cannot be created or destroyed...
gravity is just a curve in space-time due to a dent made by an amount of matter.
the analogy is usually that space-time is a trampoline and you put a bowling ball in the middle... small objects put on the trampoline will fall towards the bowling ball. This analogy is pretty good but the reason they fall towards the bowling ball is due to gravity in the first place. if gravity is a curve in space-time then is it really a force? we can describe it as an acceleration on objects but is it really a force technically?
my second question has to do with the first and creation of energy... if we have some small bits of matter just floating in space not moving (no energy) at all which is probably impossible. The small particles will start "falling" towards whatever particle is largest. Now as they start gathering at the larger one it becomes more and more massive which entails more gravity. now as they all start gathering and the gravity increases they start to become compressed and the temperature rises which is an increase in energy... where exactly is this energy coming from?
