Nilak said: Actually light cannot move in a static space beacause it automatically changes the geometry of space as it travels but you can imagine a static homogeneous infinite space before you release a EM wave, which will go straight.

All I want to say is that deviation of light occurs only where and while space changes geometry. Of course if you treat the photon quantum mechanically things get a bit messed up but again the probability to go straight is the highest.

Jerry replied: The question is “To be or not to be”. Does space really exist? Is space something? Somehow magical space does something. If space does not exist and only the electromagnetic fields and the gravitational field exists, plus dark matter and low energy dark energy photons, then we have to define how things operate in terms of these things. That leads us to classical engineering type problems and solutions. So we can look at the universe in terms of properties of space and time or in terms of the stuff within space. We then have two choices, a mathematical solution defined by the properties of space and time and an engineering solution where we seek to understand what is happening within the stuff within space.

So for the mathematical solution you say that light cannot move in static space because it changes the geometry of space as it travels. At first these words were strange to me but as I dwell on them for the mathematical solution a light wave must react with space in order to survive. Ok that makes sense for the case where space is something.

Nilak says” By newtonian mechanics, an object that travels in a gravitational filed gains kinetic energy and loses potential energy, hence no energy input. But in there is no gravitational field the object goes straight. If you magically introduce a large object with mass that creates a gravitational filed, the object will deviate from a straight line. The introduction of the massive object means introducing energy into the system. This means the object genuinely travels straight. To deviate it you need energy.

If the massive object was already present the deviation was already in progress hence no energy transfer.

That is the difference.

Jerry says: There are two possibilities. An object can have its own gravitational field that travels with it or space creates the gravitational field. If an object has its own gravitational field then this field is 13.78 billion light years in size. Thus what we see in a particle is a focal point of what it is. An alternative is that a particle interacts with the dark energy photonic field to create the gravitational field. In either case space has no properties. Other alternatives is that the various fields are physically separated from each other by tiny differences in time. Thus the positive and negative electric fields never coexist.

We then have many possibilities from space is nothing to space is everything. Photons can interact with space or photons can be independent of space. Another possibility is that space is merely a different state of the gravitational field. We say that the gravitational field has deviation in intensity and thus a direction. Yet it is possible for the field to be neutral. Thus the gravitational field can be looked upon as clay that can be molded and twisted into interesting shapes. There are many interesting possibilities for sure.
