Sunday January 20th, 2,013. mmm2 What is the shape of The Earth??
Some of you will know(Double reverse helix.0
mmmi was the previous article. I meant to put 1, but i got put.
What are the consequences of gravity as we descend?
Imagine you knew nothing about mass and gravity. At first sight The Earth seems to be flat. Either of infinite extent, or finite extent. Shaped circular – or like a table top.
Masses tend to get together, and cohere.
If you thought of The Earth as a solid round object, then at the centre of The Earth – gravity would be zero. In fact you would tend to float LONG before you reached the centre.
However, the Earth is hollow. And the centre of gravity of The Earth is the centre of gravity of the CRUST, or shell!!
At first mass would pull(actually get you PUSHED) you downwards, which is perpendicularly opposite to the zenith of the sky.
After quite a while gravity would try to move you sideways,(greatest mass being to the sides in the crust) both sideways, the result being that you would float in space WHERE-EVER you were. Downwards would be to either side, but because both ways(towards both sides)(NO force moving you downwards, NOR upwards!!), you would simply float where-ever you were!(As the sideways forces would neutralize.)
You would simply move in space, or where-ever! So provided you could SURVIVE down there, you could have a great time!
In order to proceed so to exit on the INNER surface, you would need to keep moving in the direction you originally were going. You could not know which way to proceed, unless you had some instrument that maintained your original direction. A Gyroscope could do this. So better have some of them with you!
Eventually,then, you would simply come out on THE INNER surface of THE CRUST!! And find yourself WITHIN The Earth, yet not underground!!
Once inside you could simply walk on its surface just like how you walked on the outer surface! There would be blue sky, with a small red sun way overhead.
As you approached the inner surface, you would feel as if climbing up hill. The opposite to what you felt when descending. Except that this uphill would be towards THE INNER SURFACE!!(Or you could turn around – and exit similarly back out on THE OUTER SURFACE!!)
I hope you can follow that!!
It only needs for the temperature to be not too hot,nor too cold, – and you could(given enough provisions) SURVIVE!!(If only there were no hostile humans,aliens or animals,etc. down there.)
We are taught that the further down, the hotter. Perhaps this only applies in volcanic pockets of lava below volcanoes.
Fortunately we do not need to excavate. Existing caves, like Mammoth Cave in Kentucky, would allow us to make the trip, IF we had enough provisions(or found food,etc.underground).
Alice in Wonderland and A Journey to The Centre of The Earth were concerned with reaching centre.(Alice, down a rabbit hole and The Jules Verne heroes went down various chambers.)
It was always assumed that GRAVITY would behave normally. That is like it does on the outer surface. But that is a mistake! Gravity depends upon MASS, and its distribution VARIES greatly!
Gravity does not JUST HAPPEN. Mass distribution is the key. Different masses tend to approach one another, and coalesce!
So you, and anyone, would be obliged to have regard for how MASS is distributed around you!
Up and down would only apply as you approached the outer and inner surfaces! Otherwise local mass would govern you.
You could simply move along the ground(the floor of the passage way you were on), or float through the AIR(which is handy). The problem lies in carrying enough provisions to see you through!!(Whether you are in Mammoth Cave in Kentucky OR in a man-made complex of caves below The Great pyramid at Giza.)
Are you having difficulty with the floatiing in the air idea?(Only MASSES of objects would govern! If there is no down or up force operating upon you(as would be the case when DEEP in the CRUST), and ONLY a SIDEWAYS force(In ALL directions sideways!(Visualize THE CRUST!) Then the EQUAL sideways forces would equalize.(in ALL directions around you, once far enough from the exterior edges of the crust)(only above and below exists!)would reduce to zero, and you could AND WITH EASE simply stay WHERE-EVER you put yourself, even if a few feet up in the air!(You would have to exert yourself TO CHANGE YOUR POSITION!)(Thus you could float with ease!)(ONLY when approaching the inner and outer edges of the crust would you experience UPHILL!!)(The crust is global, and 400 miles wide.)(MAYBE good place to go as Nibiru and Herbuculosis pass by!!)(When approaching large objects you would feel attracted towards them GRAVITATIONALLY.)(Slightly, depending upon their sizes.)
EVERYWHERE upon the outer surface,we feel the downward pull(push towards, actually)(We are SO used to this, that we tend to think that this applies everywhere. But it only applies on the surface of The Earth because our mass gets pushed towards The Mass of The Earth!(Due to the law of masses uniting and coalescing.)(Change the distribution and things behave very differently!!)(On the inner surface(Of The Earth(not the crust)(Though of the crust,too.) we would fall UPWARDS(towards the crust) – which would then SEEM down!)
Normally we are only aware of ONE application of gravity, and that is when we get drawn towards The Earth. But inside the crust, AND upon other planets,etc., things would behave VERY differently. Also in The Spirit World!(Where THE DIFFERENTIAL between masses is much less!)(It is the decreased DIFFERENTIAL, not the decreased mass, that lets us float and fly in The Spirit World!)
So, it is ONLY when we leave the USUAL mass distributions providing gravity that the peculiar irregularities apply.
One has to go a very long way down inside of the crust BEFORE any peculiarities are noticed.
Most of us have a healthy respect for precipices and the like. BECAUSE of the law of masses trying to unite.
