Big Splat take 2? Some theories say it all started with a splat before the bang. Or Implosion. Apparently, due to this moving to the hypothetical edges, in a couple of billion years or so, the Sun will lose it gravitational hold on the planets, and our solar system will be no more. But, the Earth will lose it's hold on the moon way before that. It's been happening ever since we got the moon, it is slipping away each year.
