I'll have ta think on that one and reread that several more times
How about a simplification...
Being a techy nerd... I like things that can pass scientific testing or at the least, have enough coincidences to make the likelihood of something being true actually being possible. Still, I'm not an expert in any of these fields, so I have to also be a little skeptical of even the things I think are likely.
It looks likely that we ( Earth etc ) goes through cycles where we are at risk of catastrophic events and the chances seem pretty likely that these are caused by meteors and/or comet when we pass through the areas they travel. The Taurid meteor stream is an example of a short term ( happens twice a year ) chance of a catastrophic event, this is almost a certainty in my opinion ( heavy on the opinion side still ). I also think there are other potentially more catastrophic events that happen at thousands of year intervals, this part still being less likely, it still seems evident given the coincidences of the events shown on Randall's charts.
Ok... the part on dimensions... other than just the 4 I know of directly... I don't want to make any assumptions. I do think the scientists have the maths that seem to prove they exist, but that alone isn't enough for me to say they are fact yet. In short, my experience level isn't enough to argue for or against it, I just don't know enough to say so I try to not make assumptions. I only have faith that they exist at best, no proof.
On the subject of planets... I can only say with any certainty that they can affect other astral objects with their gravity which could certainly affect us on Earth if one of those objects impacts us. I have no faith, therefore no belief, that they also affect us as individuals any other way.
I'll add this.. Mother nature does seem to constantly repeat certain numbers, so there are patterns that exist. The lunar cycle and the menstrual cycle are both about 27 days... but they don't appear in sync exactly so I wouldn't apply any weight to that. Many of the numbers seen ( which are repeated often ) in nature, seem to reduce down to either 3, 6 or 9. In fact, Nicola Tesla is famous for saying
“If you knew the magnificence of the three, six and nine, you would have a key to the universe.”
