What if we loose gravity of the earth for some seconds ? And also the gravity of our universe or galaxy ?

My colleagues and I were discussing what physical changes the flow of water goes through between leaving the tap and hitting the sink. This was noticed by feeling greater pressure when an object is held at the bottom of the stream versus closer to the tap.

Given that the volume of water flowing from the tap is a constant and that the water is subject to acceleration under gravity during it's fall, presumably the water stream is decreasing in diameter to maintain the same flow rate?

Presumably interference with the air would a place an upper limit on the speed at which the stream would remain together but what would this be and what would the upper limit be in a vacuum?

We all know that 2x/4x = 4x/8x does not tell us what x is because is cancelled out being referenced on both sides.

Describing  an egg as egg shaped does not tell us what the shape of an egg is.

So why do models gravity using a picture of a “gravity hole  in a mesh of time” as if the weight of a ball is distorting a frame of time. This, surly, is a circular reference effectively saying gravity looks like gravity. Additionally this model has some rather poor comparison’s. And if the mesh is three dimensional then what are the axis of this mesh?  Does this imply time have 3 dimension’s?  Showing a picture of a moving ball rotating around a gravity ball includes a reference to time to describe time itself. Giving two layers of self-reference.

Can anyone explain to the lay public what gravity is without using self-reference. ?

Dear all,

After having cooked about 40 crêpes (I'm French), I put them in a plate (whose edges are higher than the center of it) in order to form a pile.

The crepes at the top of the pile are curved, just like on this picture.

I'm sure it is due to the shape of the plate combined with gravity on top of the pile (the crepes are pulled down in their center of gravity, like the hypothetical ball on the image) but my roommate thinks that the crepes have cooked less in the middle than on the edges, explaining the shape. I'm pretty convinced that with truly uniform crepes the result would be the same. What is your explanation ?

The hole would be completely straight and heatproof. 

Sorry if this has already been answered.....

As I understand it a traditional rollercoaster obtains the energy it needs to go round the ride from the initial drop.

Therefore is a rollercoaster that has its maximum number of riders  faster / slower or alter the experience due to it being heavy?

I'm new to this and although interested in Science never really paid much attention.

I'm sure the answer to my question will be connected to the rule you learn at school about the rate of falling being the same regardless of mass (or something like that!!) I obviously never really understood it so would like someone to answer me this question relating to something i like (rollercoasters) so I can learn something new today!

Thanks in advance!
