Almost no one actually travels through space. Most just use "holodecks" to communicate with other star systems at FTL speeds. This obviates the need to go anywhere, because essentially unlimited energy (mass-energy conversion) makes complete recycling possible. That means that all these races are essentially self sufficient. Besides, why would you want to go to a distant planet, where you would probably die from a disease to which you had no immunity? Such technology makes it possible to explore the galaxy from your living room. Much as we now do by TV, but farther afield, in 3D, and much more interesting than reruns of "I love Lucy". :) Regards, R. van Spaandonk Crops, not towns, should be planted on floodplains.

... then there's a quantum concept called "afterglow" ... which could explain a lot if it were not imaginary https://phys.org/news/2015-03-photon-afterglow-transmit-transmitting-energy.html
Re: [Vo]:transmitted and reflected pulses in a medium
There is a far more interesting open question. We assume that photons "fly" straight. Of course this work fine for short distance but does this also hold for millions, trillions of kilometers? Because all mass inherently rotates all mass inherits a minimal angular momentum. We also know that all coupled rotating mechanical systems follow a toroidal path. So in fact the universe must have toroidal substructures. As matter deviates light a photon can easily travel a circle around the universe torus and you theoretically could get back the photon you once emitted. J.W.

If it does then wouldn't some of the energy of the wave pulse be reflected back to the source of the wave pulse? If this is true then perhaps something analogous can happen to light so that the observed CMB would be the echo of light from our own Sun and the redshift of a remote galaxy would be the result of light energy being reflected back to that galaxy. (According to the theory of special relativity this is a flawed analogy since it says no medium or aether is required for light, but as far as I know no experimental tests of special relativity have looked for reflections from the aether.)
