Interesting, this would also explain one reason you guys feel space travel is nearly impossible? Due to the fact that you need to exceed the limit of force required to penetrate the DEF? Also, you say that the earth emits to gravity, correct? Conversely, the stars and moon and other celestial objects do exert a gravitational force? <Feel free to correct any misinterpretations that I may have formed> So the objects in the sky exert a gravitational force on the earth, which accounts for the variable "force" experienced at different altitudes that RE claim is gravity and FE says is due to the acceleration of the DE? Now, I'm wondering. Why does the earth not catch up to the other objects due to this ever so slight gravity? Considering that their vectors should be parallel, they should combine into a slightly faster than the DE acceleration that those celestial bodies feel from just the DE?
