He said he did readings and found 12 vortexes, spirals of energy at work on our world. And I saw
a TV show that used infrared photography or something in space, and you could see "beams" coming to Earth. Do hurricanes actually start in common areas? Why are there tornado "alleys", or places of repeated tornado activity?

I understand the Grand Canyon is the gorge left after millions of years of the Colorado River weaving its way through the bedrock. Now that we have the current day condition of how the Grand Canyon appears, is our present and future global warming crisis cause for concern that the river may once again flow like it did millions of years ago? I don't know what magnitude of global warming we are discussing but I would safely assume by this time that many cities and states would be submerged underwater.

I don't know what clue or theory led me to think about this but I felt it may have been described by mathematics and the table of elements somewhere. As in, a planet has the potential to do this. What do you know about this or can reference me towards?

When it is high tide at one location of the Earth, is it low tide at exactly the opposite side of the Earth ? If so, then does it mean that gradually high tide turn towards low tide when you start going to other side of the Earth. If No, that is, the High tide is unformly at all sides of the Earth, then how can we say that Moon influences the High Tide ? It is near to the Earth only on one side.

I thought this object I have was cassiterite, pyrite, wood-tin, or something alone those lines. But with the specific gravity in the 9.13 range it's far too high for that. Any other suggestions?
