Gravity Bowling Ball Rubber Sheet

It is said that a massive object curves space time just like a bowling ball on a rubber sheet and another object near the massive object simply rolls down hill on the rubber sheet that is the reason why we observe that the other object is experiencing gravitational attraction to the massive object which curved the space time.

Gravity bowling ball rubber sheet.

This comic refers to a common analogy used to explain how mass distorts space time a bowling ball resting on a sheet of rubber distorts the sheet due to its weight. But a ball rolls on a surface because gravity is pulling it down. Hd is short for high density which lowers the rg and raises the differential of the weight block. This is the result of using a two dimensional analogy of a three dimensional universe.

Why don t we use one dimension of space and the other of time. The flaw is this. It s often misused to show that mass warps spacetime 895. If an object like a tennis ball is then thrown onto the rubber sheet the tennis ball will gravitate towards the bowling ball.

The bowling ball has a greater mass so it also has a greater gravitational force. The gravity of the situation this shape can power through just about anything. You can calculate this gravitational force as the product of the mass m and the gravitational field g. This is nothing at all like the way general relativity works.

The system has some qualitative features in common with gravity. Just placing an object somewhere in that dip will result in it rolling down the slope towards the bowling ball. In the cartoon image of einstein s explanation of gravity a rubber sheet is pulled tight and a bowling ball is placed in the middle. Both are curved by mass and everybody takes eucledean cartesian type flat graphs of say x and t as a matter of course.

Since i read cosmos long ago i see the same analogy about the balls rolling on a rubber sheet used to explain how gravity works. It thus makes it seem like gravity pulls the golf ball down because the bowling ball pulls the rubber sheet down. It isn t just warped space that s involved it is warped space time. The distortions in the rubber sheet representing the distortions in space and time.

In space it will follow a straight line and go over any hole on the surface. The point is there is no pushing going on in the general relativistic model of gravity. General relativity requires a curvature of space time not just space. A higher differential translates to more flare potential so every time the ball makes a rotation it exposes a fresh portion of coverstock material to the oil.
