##### gravity simplified?
« on: 08/11/2015 03:47:55 »
guys im not into formulas or equations but maybe gravity is simple aerodynamics - when an object travels fast through space/air it generates pressure or  G force, upward and downward. the earth is traveling and spinning so fast through space the downward pressure is great enough to cause everything under that band of pressure to stick to it. basically the earth is bending space around its mass creating heat, erosion and G force/gravity??!?!?!?!?!?!?!?

is that the reason nothing really breaks through the atmosphere unless it's a very large mass? i would imagine to break through that kind of pressure and heat the point of trajectory and aerodynamics on the object has to be perfect, im guessing nasa spent some time on this one haha.

aerodyamics shows us that the flow of air/force happens above and below but never on the actual object for eg a formula one car creates air pressure to flow about 3-5 inches above its mass. well think of the size of the earth and it;s speed. multiply that 3-5 inches by the speed of the earth, is it 100,000km/sec? or is that the galaxy? not sure but we're moving fast anyways.

does this make sense to anyone, my suggestion is that without forward motion there would be no gravity. spin alone would not be enough. BUT forward motion alone would not be enough either to sustain life as the force would not be spread evenly. spin is essential to balance the pressure of this force around the earth meaning there is never any great force applied to any one area of the earth at any given time keeping "gravity" balanced over the planet. the spherical shape of the planet is a key factor also creating an even g force. the spin has to be uniformed as well ie on it;s axis at all times.

with this air pressure or  G force being so strong i would imagine once you reach the edge of it it;s gonna throw you hard down or up depending on which way your entering. I wonder if guys who have been in space have experienced a surge of gravitational force away from the planet at the point of break of atmosphere. if so this confirm my case more. ever been driving and a fly almost hits the window but instead hits that point where the force is generated and instead of hitting window gets caught in the upward jet stream OR totally splats in the windows full force. if your car window is aerodynamic the fly will usually go up, if your window is flat or kind of flat its always gonna be splat. but anything that sits just under that airflow is fine until your speed rises.

forward motion=Gforce+pressure = unbalanced gravity
forward motion+spin+spherical shape = G Force+pressure = balanced gravity

anyone care to put a formula onto this? gravity has to be the G force generated form the planets fast movement through space.

if the earth was to start going faster through space the gravitational pull/G force would be stronger as the force generated from that pressure would be greater. if the earth was to speed up suddenly we would all die as the pull/G force would be too much and if it was to slow down we would experience weightlessness. if it happens slowly evolution will keep things in touch obv as all life evolves around its surroundings. another scenario is if an object is flying through space and it;s not spherical then there will be a massive change in gravitational force at different parts of the object due to the spread of gforce generated with forward movement. its called air resistance as well or something not sure.

with this theory as well if an asteroid of great size did hit the earth and slow it down quickly or stop it spinning so fast we could all float into space unless we put bricks in our pockets lol. water would also become lighter forming a ring around the planet (venus)???

this to be seems perfect reasoning for the force we call gravity. i haven't heard anyone else think this way - is it too obvious or not? I'm sure if you put a grain of sand on a tennis ball and threw it fast enough with a uniformed spin it would still be on the ball, actually i take that back because the force generated from you throwing it would be enough to throw it off. if however you could get the sand onto the ball as it was flying and spinning then. to clarify the forward motion we are moving forward but in a way water moves forward to run down your plug hole. round and round and round getting closer to..................... yep thats right our solar system, earth is being sucked into a black hole. over a time frame we can never conceive but its happening all the same.

let me know what you think guys or if this is just the rants of a madman??!? i'll close for now haha

No, your idea is wrong in so many ways, space as no air, gravity is still on the moon, it is good that you are thinking for yourself, but no your idea is wrong, think again take a different angle of thought.

what do you mean gravity is still on moon - it appears on every planet that has forward motion and spin. the resistance caused by this forward motion is g force, g force happens in space or in "air" it doesn;t have to be air. any forward motion anywhere causes resistance which in my eyes is gravity.

i'm afraid your answer lack any substance and detail and it appears like you have completely misunderstood what i said

anyone else?

We have had lots and lots of conversation on gravity, I assure you it is nothing to do with spin.    For two objects to orbit each other and spin they firstly have to be linear attracted.

Spin is a product of force and not the cause

ok i see that. lets take away spin for the moment then

what about forward motion? go in a fast car and it will throw you back in your seat - or a rollercoaster for example. we know the earth is traveling at a rate of 1,000 m p/hr? don't quote me on that as "apparently" that's how fast we orbit the moon not how fast the whole solar system is moving through space.

are you able to tell me where the g force from that speed goes?

Forward motion?   Do you mean perpendicular to gravity?

Either way, imagine standing in the middle of a road, imagine a car travelling towards you, the car will knock your legs from under you if the car hits you, the car applies a force on you greater than the force that holds you to the ground making your gravitational balance unstable.
When you are in the car   and accelerate, the force of gravity is still pulling you down centripetally towards the center of mass(earths core) where mass is at its densest by compression of matter.
The force of the car being forced to travel perpendicular to gravity , ''knocks you off your feet'' pulling you back into the seat, the seat wants to knock you over because you are not moving, it is the car that is moving forcing you to move with the car.

As for where the G-force from the speed goes , I am unsure what you are asking.  Energy is transferable and like wise force, kinetic loss and kinetic gain and when speed is a constant to gravity rather than an acceleration, we find our balance again .

Deejayms, I think your theory needs some tweaking.

The force you feel pushing you into the seat of a car is from acceleration, not from speed. You can feel a very strong force by flooring the gas from a dead stop, even if the top speed reached is only 20 kph. But on a highway one can comfortably go over 150 kph as long as the path is straight and they don't speed up or slow down. Have you ever been in an airplane? You can be going at almost 900 kph without noticing.

But you are on to something, you just need to consider acceleration rather than speed. Einstein was able to describe the apparent equivalency of a frame of reference in a gravitational field and a frame of reference under constant acceleration (general relativity).

Imagine you have a lattice with small balls all interconnected via springs. Now you tie wires to the back of the lattice, one to each of the balls at the back and pull it forward. The balls at the back will start moving forward and the springs will compress. The row in front will eventually start to move and this compression will propagate through the whole lattice until it all moves but now compressed. Now imagine attaching wires to every ball in the lattice and pulling forward. Now there is no compressive effect so no 'feeling' of acceleration. This is the difference in acceleration due to an external force and gravitational acceleration due to free fall. This time with same wires tied to all the balls vary the rate at which the wires are pulled from the back of the lattice to the front. Those in front being pulled faster than those behind. Then you have tidal forces.

guys thank you so much all for your input!!

I'll try to put it far more simply

A racing car going at 100 m p/hr sticks to the track,it does this because of the down pressure created with aerodynamics.

earth traveling through space at 100,000 m p/hr has to create a lot of downward pressure. RESISTANCE

why do most things burn up coming into our atmosphere?! because the earth is moving so fast it generates a wall of resistance and heat

i'm not saying gravity is all downward pressure but it a massive part to play.

i think people need to expand they;re mind to see how fast we're flying through space. and what makes us move and spin so fat - some theories are a black hole is pulling our solar system into it. light years away obviously but it would explain why the planets are not standing still

Well,
Please remember your ideas are moving on things that falls within gravity.
we have to keep in mind that climate plays key role in Gravity.

Here i believe that earth has nothing to do on so called gravity.  For example on moon there is weak climate and thus weak gravity and on earth we are having strong climate and thus strong gravity.

Let me tell you that i am not a scientist, however out of interest i had written a theory on "Gravity".  As per my theory it is energy that plays
key role in gravity and it is not pull effect, but push effect.

OK i will try to post my theory in naked science soon.

I suspect there is a clear relationship between the amount of mass and the attraction of gravity. Atmospheres are non existent with the ratio of mass to attraction is consistent. Observation would suggest climate may effect weight but unlikely be the cause of gravity attraction.

What you are describing here is acceleration not motion. Motion if it is constant will not throw you back in your seat. Only acceleration will and we have known for the last 100 years that there is no perceivable difference between acceleration and Gravity. Nothing new there.
For a real simplification of Gravity that is new and doesn't contradict any of the observational and experimental data so far collected by Humanity, check out the link bellow.
