Time Travel

Here I am trying to describe my thoughts about the time and curvature of space and time.  Now we can imagine a sphere which undergoes an explosion from its center and the parts of the sphere is scattering into all the dimensions of the sphere, and continue its motion [1].

This figure shows us three stages of the sphere ie; the sphere before explosion, few seconds after the explosion and sometimes after the explosion. Now here I am going to concentrate some parts from the expanding sphere to describe the curvature of space - time and force of gravity.

I am taking 5 parts from the expanding sphere (objects A, B, C, D and E). We can imagine it as the expanding universe too. We know that all these parts are moving away with a uniform velocity. Now imagine that an object is travelling from “B” to “E”. While it is reaching to the point “E”, the object “E” is also travelling, so the object “E” will be at the point “F”. Here we can observe the curvature of time and space directly. This figure shows us the difference in distance between the relatively moving objects. Once the object starts travelling from “B” to “E”, it is travelling in a straight line. But here the destination of the travel “E” is moving towards to “F”. So the object which is travelling to “E” has to follow the motion of “E”. If it follows the motion of “E” the path of travel must have to curve. It is not happening here. We can see that the object which travels from “B” to “E” is always travelling in a straight line. So here space and time is getting curved according to the travel and gravity is directly helping the object to getting a curved space and time. If gravity is not holding the traveling object in it has to follow the motion of “E” and the travelling path must have to curve. So here we can see here the influence of gravity. So we can clearly say here that gravity is keeping the moving object in a straight line. That I am explaining below.
