This presents me with another hypothesis: multiple minor planets may have been the cause of gravitational fluctuations... I'm working out every possible explanation in my head.
The channel I got my information from is scientific, and I only believe the most reasonable channels, such as, riddle, unveiled, and what if. (what if is theoretical possibilities)
Stephen Hawking describes what was before the Big Bang as, "The Big Bounce" where the entire universe never ends, but compresses and decompresses itself. A theory I believe in.
I don't have a link, but you can search "ninth planet" and also, the forum question is "Is there a ninth planet, if so, what do you think it looks like?"
