What is there beyond the stars?
My notion, for what it's worth, begins here:
The toy of five or more steel balls, hung from a trestle by string, demonstrates how wave energy travels along from end to end. Ocean waves do similar work in carrying energy across the face of the earth undiminished.
All manner of radiation is brought to our earth's surface from the sun and wider cosmos. The puzzle is to discover what the transmitting medium is between these motions.
Sound waves require air or a liquid to travel in. But a vacuum transmits no sound.
Therefore it seems logical to suppose that all waves, of whatever wavelength, require some medium, through which to travel.
Light itself is one of those wave forms and presumably requires a medium in which to propagate. The denser the medium - the faster the travel of waves. Light may be travelling through a medium that is the most dense of all, since it travels at the fastest known speed.
Now consider just what that medium could be.
Invisible, unyielding and unbroken across the whole of our cosmos.
Is this a weightless solid body composed of matter that transmits light at a specific speed - the speed of light?
Our cosmos is criss crossed by light that shifts into the red spectrum the further it travels. Distant objects being shifted along the spectrum, supposedly indicates the distance of those objects from us. We are led to believe that because of the red shift observed in the wavelength of light, the distant cosmos is rapidly moving away from us and therefore expanding in every direction away from where we are, described as the Doppler affect.
I find it hard to accept the finite nature of an expanding cosmos - a specific big bang event.
