Simple dark energy explanation: What does vacuum consist of? Does empty space have weight or mass?
Light on the dark energy mystery
Vacuum has physical properties. That is a fact. Notably permitivity and permeability. Permitivity and permeability together can be used to calculate the speed of light in a certain medium, including the vacuum. Permitivity affects the capacity of a capacitor and permeability the inductance of an inductor. That's why we use materials of high permitivity in capacitors and high permeability ferrites in inductors.
So, is vacuum a "repulsive force"? Oh yes, indeed it is! If the permeability and permintivity of vacuum were half of their current value, speed of light would be twice of its current value. More than that, permitivity and permeability affect the maximum speed of anything, anywhere. As we said earlier: if materials (like water for example) have higher permitivity, permeability the speed of light will be slower there. But that implies the water IS there. If you take out all the water, the empty space still has physical properties.
I would like to point to Dirac, as he is presented by George Gamow in the book "Mr. Tompkins in Paperback". He talks to a dolphin that does not realize that he lives in a space filled with water. The same way, we do not realize we live in a space filled with space.
To explain the above: the space we live in consists of three independent dimensional axis and one time axis. We live in a defined space! Out of our space, with no permeability and permitivity, existance of matter would not be applicable. We live in a 3-dimensional material world. I think that explains the "dark energy" case pretty well. Simply "NOTHING" CAN NOT HAVE PHYSICAL PROPERTIES. ONLY "SOMETHING" CAN HAVE PHYSICAL PROPERTIES.
So, even empty space must be of some value, since it is a 'defined space' which is even measureable. Thus the problem of "repulsive dark energy force" should not come as a surprise, and we again need to admit that there might be some cosmological "aether" as is the medium trough which radio waves travel nostalgycally called to these days.
We all see water having "repulsive force" on ships that slows them down, yet we thought that vacuum would not have such properties on matter, how foolish we were. Vacuum allows magnetic force to pass trough and it allows existance of electric field too. In other words, vacuum consists of some transfer medium, which I call "defined space" to transfer those properties up to a speed limit defined by permitivity and permeability of the vacuum.
