The speed of light and time travel are totally unrelated - light is just light and sound is just sound - they have no magical qualities...
Personally I think Einstein was a fraud and a quack and his therories pure publicity bunk. Why is the speed of light "the fastest speed" possible?
Because no one has yet detected anything traveling at higher speeds, but that should not mean that there is nothing in existence that cannot travel at
speeds faster than light, and light is only picked on as an example because we can see it - gets kinda hard measuring speeds of something you can even
see. Whats more, the speed of light is variable (not finite) it all depends on what medium the light is traveling through - that fact alone, that
light has variable speeds kicks at least half of Einsteins theories right up the butt...
Light that travels through transparent matter does so at a lower speed than c, the speed of light in a vacuum. For example, photons suffer so many
collisions on the way from the core of the sun that radiant energy can take about a million years to reach the surface, however, once in open space, a
photon takes only 8.3 minutes to reach Earth. Light of different frequencies may travel through matter at different speeds; this is called dispersion.
In some cases, it can result in extremely slow speeds of light in matter.
We are all already travelling at 370 miles per second (1 million 332 thousand miles an hour) as our galaxy moves through space relative to other
galaxies, and all that bunk about things becoming heavier or shorter or clocks going backward as speed increases hasn't started being noticable
The thing is, light is just photons radiated off, and reflected off surfaces that illuminate and allow organisms/animals/etc. to see - it has no other
magic qualities about it other than just that. Attributing time travel, shape changing, arriving before you left, and all that other bunk that
Einstein and others proposed is simply just the stuff of childrens fairy stories.
Whether you sit still and do not move, or move around frantically at any speed, time continues its course just like it always has done, the lives of
insects are measured in months, the lives of humans are measured in decades, the lives of galaxies are measured in eons.... from our point of view of
course... and it will always be measured from our point of view, because we are the ones doing the traveling.
Yes I firmly believe travel at and beyond the speed of light is perfectly possible and achievable, although it will require a propulsion system that
we currently do not have.
As for the fact that the galaxies at the edge of the known universe can be observed, we are only seeing the light emitted from them, nothing more - no
need for time travel expanations - it is just their light - those galaxies probably ceased to exist eons ago - the fact that we can still see the
light emanating from them is just a curious quirk of nature which works to our benefit with astronomy - there is nothing in that which is mystical or
magical or worth basing a whole theory upon.
As for needing huge amounts of energy (such as boat loads of jupiters) to power your spacecraft that also is untrue - a spaceship will keep
accelerating for as long it has fuel and until it reaches the velocity of it's thrust...
Our own spaceship, Voyager 1, is continuing to accelerate as it moves out of the solar system - its terminal velocity is unknown, but it is on a
hyperbolic trajectory and has achieved escape velocity, meaning that its orbit will not return to the inner solar system. It's current speed is
38,016 mph, and subject to the gravitational pull of other interstellar objects its speed will slowly increase over the decades to come.
Perhaps with the discovery and harnessing of more exotic particles, exceptionally powerful thrusters will be possible.
Star Trek might well have touched on the possibe future... Plasma drives, controlled release anti-matter drives, etc... seems the way to go... just
keep an eye on hull friction... space is not empty at those speeds.
Just my 1 cents worth... but yeah, damned interesting subject...
