So I stumbled upon a video on the internet which made an analogy of mass creating a curve in the blanket of spacetime in which objects of smaller mass rotated about it. Which lead me to belive this is gravity. But aren't there billions upon billions of things within the universe which have mass? The correct answer is yes. So it got me thinking that the whole universe is a downward cone towards it's center while the smaller masses create ripples along the sides of the cone while we are all spiraling towards its centre slowly and surely (over vast amounts of time... hence spacetime) and once all matter gets to the centre again, Big Bang again... now I'm not sure what would cause a "Big Bang" but this is what i trailed off towards when my proffesser started the lesson with "Work is equal the amo...." then i tuned out and started thinking of cooler things.... I had to write that down somewhere. Now I'm by no means master of math, but I think my theories are along the right lines.
