Thumbs up Is Space Really Empty

Space is supposed be a perfect vacuum and that is the reason why all heavenly bodies are in perpetual motion by orbiting one or the other bodies. In a perfect vacuum there is absolutely no friction. The only objects that do not seem to orbit are the super massive Black-Holes at the center of all galaxies.

What causes a perfect vacuum state to deteriorate? The presence of solid matter whether molten or otherwise or a liquid that does not vaporize in a vacuum will not affect the vacuum state space. Only the presence of a gas in sufficient quantity reduces the vacuum pressure.

But even though space seems to be empty and a vacuum it is actually brimming with energy of all sorts. All the waves in the electromagnetic spectrum which posses and transmit huge quantities of energy at the speed of light are always present in space. This of course includes our sunlight. But why does the presence of such huge levels of energies not affect the vacuum state of space? This is actually because the photons present in these waves are Unimaginably small and very widely spread out. If an object is exposed to sunlight for one second it will be struck by energy held in approximately 186.000 miles of the sun's rays or the speed of light. Now if we imagine that the sun's rays are frozen we will get an idea as to how dilute or weak it actually is and this is the actual state of these waves in space. The sun's rays appear hot and bright only because it is being transmitted from the sun ay the speed of light. Since these energy waves are dynamic and do not accumulate in space they do not alter the perfect vacuum state of space.

Default Is Space Really Empty

Erm and why did we need to know this.
I think the emptiness of space first makes me wonder about the term empty.
For example, if the universe is getting bigger and expanding faster and
faster, given that light is a finite speed governing radiation, then the
only way you can get red shifting is to make the space bigger while the
light is in it, stretching the waves longer.
This means that if you can make it bigger, then by definition it has to be
something, noyt nothing.
Here a a question for you, many of the energies that keep things the way we
expect are reversable in that you can use the forces generated to repel or
attract, however Gravity seems to us to be a monopole. This is obviously not
right is it. No go off and sort that out and I'll go back to bed...
