Scientists have been asking about the medium that this electromagnetic wavelength would travel through for ages yet have they considered their vacuum to be that condition without medium and therefore concluded indefatigably that the light crosses the void?
It appears they have not for they are yet seeking to understand cosmic truths on their own terms.
That is all well and good but we must ask ourselves have they sought to understand themselves as of yet?
I'm afraid not, otherwise they would know we are of the stars.
Of this one thing I can remain certain due to an inescapable chain of perfect logical association.
For what are the stars we see magnified when we peer through our most powerful telescopes but the images reaching us projected from before their long ago demise?
But what does that even mean?
The answer is simple and has been staring us in the face all of our lives.
It means we are still alive.
We are right now that one Sun out there blazing bright throughout the eternal night that are yet alive to experience the incredible rush of our headlong flight.
As to another world and another time, "So what!" I exclaim.
Our world here now still burns in its familiar glow.
As humans our sight is granted in part by the presence of light itself which is picked up on (through our eyes) as the visible portion of the electromagnetic spectrum.
Light is thought to be emitted and absorbed in tiny "packets" referred to as photons.
Many photons are referred to as quanta.
Photons are sort of imaginary particles we've devised in order to help us comprehend the nature of light and radiation itself.
Non-ionizing radiation includes radio waves, heat and the visible light that reaches us from our Sun (as opposed to ionizing radiation which is ultraviolet light, X-rays and gamma-rays reaching us from way beyond our lone isolated star).
Nestled in between the invisible shorter ultraviolet and the longer invisible infrared wavelengths we are comfortably placed in a cradle of visible light.
Light exhibits wave-particle duality like any form of electromagnetic radiation.
The spectrum goes something like this:
|radio, microwave, infrared...
...ultraviolet, X-rays, gamma-rays|
This spectrum should offer us a clue as to the property of our existence out here circling this lone star gracing a spiral arm of our slowly rotating galaxy.
We emerged from an old radio broadcast that overheated and squeezed us out of the infrared zone until after another period of cooling off which we are all enjoying very much we will ultimately overheat once again going supernova and beyond into the ultraviolet as gamma-rays ourselves.
We are not yet stardust.
