All good fun and likely all nonsense. I suspect that FTL travel is
possible only using worm hole concepts and that should be safe enough
provided one moves to low curvature points to avoid instantaneous
acceleration been applied. I am sure there will be other tricky
issues as well once the core technology is mastered.
In that scenario, the view would merely change completely. It is
likely also that actual movement will be in short hops to have line
of sight of any close by objects and it may be more energy efficient.
Warp drive remains a concept unlikely to be competitive with an
effective worm hole strategy in the end which I suspect to be
practical as more conforming evidence washes up.
Warp Speed: What
Hyperspace Would Really Look Like

The science fiction
vision of stars flashing by as streaks when spaceships travel faster
than light isn't what the scene would actually look like, a team of
physics students says.
Instead, the view out
the windows of a vehicle traveling through hyperspace would be more
like a centralized bright glow, calculations show.
The finding
contradicts the familiar images of stretched out starlight streaking
past the windows of the Millennium Falcon in "Star Wars"
and the Starship Enterprise in "Star Trek." In those films
and television series, as spaceships engage warp drive or
hyperdrive and approach the speed of light, stars morph from
points of light to long streaks that stretch out past the ship.
But passengers on the
Millennium Falcon or the Enterprise actually wouldn't be able to see
stars at all when traveling that fast, found a group of physics
Masters students at England's University of Leicester. Rather, a
phenomenon called the Doppler Effect, which affects the wavelength of
radiation from moving sources, would cause stars' light to shift out
of the visible spectrum and into the X-ray range, where human eyes
wouldn't be able to see it, the students found.
"The resultant
effects we worked out were based on Einstein's theory of Special
Relativity, so while we may not be used to them in our daily lives,
Han Solo and his crew should certainly understand its implications,"
Leicester student Joshua Argyle said in a statement.
The Doppler Effect is
the reason why an ambulance's siren sounds higher pitched when it's
coming at you compared to when it's moving away — the sound's
frequency becomes higher, making its wavelength shorter, and changing
its pitch.
The same thing would
happen to the light of stars when a spaceship began to move toward
them at significant speed. And other light, such as the pervasive
glow of the universe called the cosmic microwave background
radiation, which is left over from the Big Bang, would be shifted out
of the microwave range and into the visible spectrum, the students
found.
"If
the Millennium Falcon existed and really could travel that
fast, sunglasses would certainly be advisable," said research
team member Riley Connors. "On top of this, the ship would need
something to protect the crew from harmful X-ray radiation."
The increased X-ray
radiation from shifted starlight would even push back on a spaceship
traveling in hyperdrive, the team found, slowing down the vehicle
with a pressure similar to the force felt at the bottom of the
Pacific Ocean. In fact, such a spacecraft would need to carry extra
energy reserves to counter this pressure and press ahead.
Whether the scientific
reality of these effects will be taken into consideration on future
Star Wars films is still an open question.
"Perhaps Disney
should take the physical implications of such high speed travel into
account in their forthcoming films," said team member Katie
Dexter.
Connors, Dexter,
Argyle, and fourth team member Cameron Scoular published their
findings in this year's issue of the University of Leicester's
Journal of Physics Special Topics.
Editor's Note: This
article was updated to correct the following error: As an ambulance
moves closer to an observer, its wavelength becomes shorter, not
longer.

Earth's atmosphere functions as a magnifier for terrestrial observing occupants to the entire universe. Once past the outer limits of Earth's atmosphere, a human cannot see any stars but just black space. So the occupants of an object accelerating below warp drive could not see stars therefore they also could not see stars when accelerating to warp speed. As soon as I was made aware of atmospheric magnifying scientific fact, the Hollywood productions that include NASA's Apollo program transform into nothing more than fantasy in one's higher consciousness.
to SpiralFree.... This has become my new favorite space photo! Look closely into the windows of the Cupola on the International Space Station: That’s astronaut Ron Garan, on September 16, 2011, his last day on board the space station. “That’s me in the cupola of the International Space Station off the coast of Australia taking my last of over 25,000 pics that I still want to share with everyone,” Garan wrote on his Google+ page. Not only are the colors and view spectacular, but this has got to be one of the best destination photos ever — not to mention a priceless keepsake and memento for Garan from his expedition on the ISS.
