# Directional momentum in the vacuum; you say

Common physics will tell you one very simple fact. In order for an object to begin, or increase a directional momentum, force needs to be generated against an external object. To better clarify what I am talking about here are a few basic examples of what I mean.

In order for a dog to gain momentum in an upward motion force is generated in the dog’s legs as the animal propels itself upward as a result of pushing off of the ground beneath it. The same can be said about a bird in flight or a fish as it swims. In order for the bird to gain and or maintain momentum as if flies, it must use its wings as it generates force against another, all be it, outside force generating object. In the case of the bird that outside object is the air. For a fish, the forward momentum is clearly derived from its fins as the fish generates force through the water that engulfs the creature. The dog pushes off of the earth. The bird pushes off of the air. The fish pushes off of the water. Seems simple enough, right? In order for an object to generate momentum it needs to generate force with the assistance of another object.

So… what about the vacuum of space?

Let’s actually set aside for a moment the fact that I could not find a “real” photo of a satellite, and take note of the propulsion method being used by each object as it transverses the vast expanse of the cosmic void.

Something doesn’t seem to add up, and I have to ask myself… what are these objects pushing off of in order to generate the momentum they need to travel through the vacuum? The one on the right shows multiple short range burst of energy that allows the object to twist and pivot in any direction it desires. How is it possible for an object in space to generate momentum in any direction without the aid of an outside object to generate force? Because, if the vacuum is exactly that… a void (nothingness), then when a satellite attempted to use a propulsion system such as this it would do absolutely nothing. The compressed energy as it is dispensed will be released into the vacuum and with nothing for that energy to press against, the object would not gain or reduce any existing momentum.

With that in mind let us think then about the possibility of space exploration. If we went to the Moon, and if we plan to visit Mars, then how did/can an object traveling through the vacuum slow down its momentum with this style of propulsion system in an attempt to establish orbit? Whatever speed and direction you were traveling when you left the surface of the earth would be all there is. No changing direction. No speeding up. No slowing down.

An object in motion stays in motion unless acted upon by an outside force. And since the vacuum is nothingness… any attempts at generating an “outside force” would result in nothingness. Pushing against nothing will generate nothing.

Space travel is fake. But what do I know, right? I’m just ignorant.
