i am no expert in Physic, but found this regarding the
"experience of
time slowing" of a person in a spaceship.
from the Physics expert, QnA:
http://experts.about.com/q/Physics-1358/Time-travel.htm
Question
If a spaceship is traveling at the
speed of light and time is slowing so
say how does the spaceship travel the
186,000 miles in a second?
Answer
First of all, let's change your question to "spaceship is traveling
CLOSE to the speed of light". Anything with mass can not travel at
that high a speed.
Now let's explain what we mean when we say "time is slowing." The
situation is as follows:
Someone is in a spaceship. I won't say "standing still" because one
of Einstein's postulates is that motion can only be described as
relative to something else, so you can say that the person is
standing still relative to the spaceship she is in.
Anyway, she sees another spaceship going by at 99% of the speed of
light IN HER REST FRAME. She looks at the ruler, the clock, and the
kilogram weight on that ship. She says "How odd: the clock in that
spaceship is going slow, that ruler is too short, and that mass is
more than a kilogram."
Meanwhile, the person in the second spaceship looks at the clock,
the ruler, and the kilogram weight in the first spaceship. HE says
"How odd: the clock in the ship stationary to the stars is going
slow, the ruler is too short, and that mass is more than a
kilogram."
It's important to emphasize that BOTH people are correct in how
they view the other's measuring devices: in THEIR own frame. If you
make the first postulate (No way to tell if you are moving or
standing still EXCEPT relative to something else) AND the second --
No matter what frame you are in, light will always be measured as
traveling at the same speed -- and then do the math, you get these
results. It's a bit confusing, I admit, but experiments have shown
this is what happens.
some "abstruct" illusions there.
