I saw this movie AGAIN! :)
I liked the Einstein / Light travel dialog.
=============== Potential Spoiler ====================
SEE THE MOVIE FIRST!
==============================================
The doctor questioning him wants to know how he got here and he said he harnessed
his energy onto a beam of light or something to this effect. He then said that they would
travel and many times the speed of light and when told that Einstein said that nothing can
exceed to the speed of light and Prot told the doctor he was wrong.
Prot commented that what Einstein really said is that nothing could exceed up to the speed
of light because its mass would become infinite but that Einstein said nothing about entities
already traveling at or above the speed of light.
I am thinking in the simple situation when we travel in a jet plane, we at first are strapped
into our chairs with seat belts and all, as we take off the tarmac and go "full-throttle", we
are temporarily enduring the displeasure of the G's against our bodies, as we are traveling
into the atmosphere and away from the Earth, until we reach the cruising speed (acceleration
=~ 0, velocity =~ 550MPH) only then can we unbuckle and take a walk in the aisle or go to the
bathroom. But of course if the plane deviates from a straight line path, acceleration is no longer
zero. But I am thinking out loud: "Acceleration =0 if velocity=constant and is traveling in a straight
line?" - but is this statement true even in a vacuum or more specifically: "If there are NO gravitational
forces acting on the object (plane/spaceship/...) due to the presence of large bodies such as planets,
suns, asteroids, and such as in space travel?
So, is it possible to maintain acceleration and velocity to safe limits so that stresses acting on mass is
maintained in slow steps as we approach the speed of light? Or, is it true that regardless how slowly we maintain
the stress of acceleration the mass will lose "cohesion" due to it's internal chemical bonding such as electrons,
protons, and/or neutrons will fly apart? As for traveling in the speed of light, shouldn't the "flight path" be
made so that there are no effects of gravitation forces from the galaxies, stars, planets, asteroids, ... so as
to keep acceleration to it's maintainable minimum?
Interestingly, I read in the following supplied link that acceleration has to somewhere below 4G's
as 4-6G for a short period of time can cause visual impairment or a total black out.

Of course, one comes away thinking that Prot himself is not human as he says, ie something of a
possessing "spirit", which perhaps massless except for Robert himself so we come away thinking
that light travel is entirely possible because there is no mass to deal with and Prot is, perhaps something
of (souled?) light being himself? Interesting!!
Sorry for my incessant babbling - this movie got me into thinking of many possibilities...
OSIT.
