  2.7    Are Gravitational time dilations Special Relativity time dilations?

This way to looking at gravitational time dilations (as EVVs) may lead to think that these are real Special Relativity effects, that space is falling to Earth at the escape velocity.  The problem with this view is that geometry does not support the concept.  The escape velocity would have to be an inverse function of the square of the distance and that is not the case.  The only way that this could be true is if space is being compressed as it falls to Earth.  Think of it as solar wind in reverse.  This may sound very exotic; but, is it more exotic than the warping of space time?  It is certainly no more exotic than exceeding the speed of light while falling into a black hole, a problem that it would solve.  

Let’s entertain this concept for now, and explore its consequences and evidence. 

Current theory of the universe tells us that the universe is expanding due to the expansion of space.  New volume of space is coming out of nowhere.  Given the symmetries that we have observed on other areas of nature, if space is capable of expanding, it should also be compressible.  At this point there is no risk that we may run out of space, on the contrary, the current thinking is that the universe will expand forever.

If there is a source of new space in the Universe, there should be also sinks of space, again, invoking natural symmetry property.  Is matter a sink for space?

We also need to change the fabric of space, from a rubbery stretchy sheet into something more akin to a gas.  This change means that there are no fixed locations in space, as there are none in gaseous bodies.

Once we make these assumptions, gravity is not pulling on other matter, gravity is pulling on space itself; what we experience as gravitational pull is nothing but the effect of space accelerating through us as it falls to Earth.  What we call gravitational time dilation is just a Special Relativity effect of the speed of space as it moves around us.

Let’s call this hypothesis Simple Model or SM for short.

Here is list the consequences of the concept  (not evidence):

·    In this frame, objects that are placed at rest in space near the massive object, start to move towards the mass, are being carried towards the mass, even though the object cannot ‘feel’ any change in motion.  That is what is normally called free fall.  The object is not accelerating with respect to space, space is accelerating and dragging all objects along.  It is the acceleration of space that causes the drag and not the speed or motion of space. Space has no viscosity for motion.

·    Moving objects will also have their trajectory altered the same way as in a gravitational field or they could go into orbit around a massive object.

·    All other predictions of gravity can also be equally explained; we will also see bending of lightwaves, red-shifting for waves moving away and blue shifting for falling waves.  A BH is just a place where space is falling faster than light below the event horizon.

·    It certainly does away with any distinction between gravitational and inertial mass.

·    The model is quite good, in that it follows the current formulas for gravity.  In most respects is equal to our experience with Einstein’s General Relativity, but in this case, space is not warped, it is accelerated, compressed and absorbed by matter.  

·    The equivalence principle becomes more equivalent:  rockets accelerating through space experience the same effects as stationary rockets in accelerating space, there are no time dilation effects in either case due to gravity or acceleration; clocks in free fall do not slow down, not for gravitational fields, nor for increasing speed.  Free fall means that they are moving through accelerating space, and when moving at the escape velocity, there are no changes in time dilations.  This point will need more elaboration in the future.

·    This concept is capable of explaining the issues presented on Section 2.1 and 2.2.  The Michelson-Morley experiment has been performed with light traveling a path that is parallel to Earth’s surface.  When the experiment is run with light following a path perpendicular to Earth’s surface, the results maybe decidedly different. The GPS constellation of satellites does not go out of synch.  Objects in the area where Earth’s gravitational field is dominant, will not experience time dilations due to Earth orbital motion around the sun, they will only be subjected to the time dilations due to their motion with respect to Earth.  But it really goes beyond that.  It also means that they do not experience gravitational time dilations due to the sun’s gravity either.  The warping of space-time in the solar system should look as shown in Figure 9 below
