No, gravity does in fact act on massless particles.
No, because objects without an electromagnetic field still produce a gravitational interaction.

If there is a genuine "slowing down" effect coming into play, and because there are no significant gravitational masses at that distance to play a significant role, I'm just wondering whether what we're seeing is indications that space itself is not homogenous.
Instead of assuming that the regions of space that the probes pass through are all of the same "density", what if space does indeed possess a property similar to "density" that affects the velocity of the probes by imparting a "impeding or drag" type of force ? The fact that virtual particles are being created/destroyed continuously in otherwise "empty" space immediately implies that space is not completely and totally empty and therefore must exhibit "density-like" properties.

Could this explain Einstein's theory of the fabric of space? Just thinking based upon how it was explained to me as a ball on a bed sheet it creates a slight curve in turn the object when traveling away it would be going uphill possibly changing the course of motion?
"After launch, a spacecraft accepts electrons from the surrounding space plasma until the craft's voltage is sufficient to repel further electrons. Near Earth it is known that a spacecraft may attain a negative potential of several tens of thousands of volts relative to its surroundings. So, in interplanetary space, the spacecraft becomes a charged object moving in the Sun's weak electric field. Being negatively charged, it will experience an infinitesimal "tug" toward the positively charged Sun. Of most significance is the fact that the voltage gradient, that is the electric field, throughout interplanetary space remains constant. In other words, the retarding force on the spacecraft will not diminish with distance from the Sun. This effect distinguishes the electrical model from all others because all known force laws diminish with distance. The effect is real and it will have a fundamental impact on cosmology and spacecraft navigation because Pioneer 10 has confirmed the electrical model of Stars!"

other evidence that our theory on gravity is BS is...eliptical orbits.
eliptical orbits support the electromagnetic theory.
gravity states, the moon would spiral closer and closer. untill it collides with the earth.
well its been thousands of years if not miilions...why has it not got any closer.
the eliptical orbit shows the moon repels the earth as well as being attracted to it
i agree with gravity to an extent...but, the moon not spinning on its axis supports the thoery that the suns eectromagnetic attributes cause polarity for its satelites.
earth doesnt emit strong electromagneticenergy as the sun
the earth cannot give the moon polarity the moon is trapped by the earths polarity which in turn is trapped by the suns.
im gonna outdate the word gravity...lol

Maybe Gravity is a stronger force than currently believed. We know about gravity on Earth. We know a great deal about gravity in space around Earth. But we don't know squat about Gravity outside our Solar System. Seems our Sun has a stronger pull on objects than previously thought.
By the way can you believe it has been 40 years since they were launched. I remember when they were launched and remember the pictures they sent back from our Solar System. I was 12 when the first one was launched. I also remember waiting for the pictures of our Solar System, and was amazed at the beauty when I did see the pictures of our Solar System.
Too bad our government hates the exploration of Space. That should be our number 1 focus. Seeking out new worlds to expand the human race.

The so called "Pioneer anomaly" known in the gravitational physics community is not new. Unfortunately the force has not been formulated. That means it has not been mathematically clarified.
They do know though something other than Newtonian gravity is at work. But that is not enough to make such a big claim. There is other theoretical claim of additional gravity known as "dipole gravity" proposed by Dr. Eue Jin Jeong. I think it is more credible than the experimental observation made by Pioneer anomaly. But then these two could be related. In fact, the additional attractive force confirms to the model of dipole gravity. And also the dipole gravity decreases proportional to the inverse r squared which may fit the conclusion derived from the Pioneer anomaly.
