'PIC space ship (how to live longer?)'

Uh, actually, the time dialation would cause one to age slower as the ship
is moved faster. Therefore, if you have a ship that goes near the speed of
light, 27 light years could be covered in several minutes or less. Of
course, if you went the speed of light (not possible?), you wouldn't age at
all, and science fiction and some theories have all sorts of stories from
then on.

The only troubling thing is avoiding (deflecting?) all the small particles
floating around in space. One tiny pebble at 99.9999% of speed of light
could potentially ruin your day. I suppose we could use a PIC controlled
particle beam gun of sorts to blast them. Do you know if MChip is planning
a _real_ fast version of 16C84?  ;-)

Personally, I wanted to use "According to Dr. Einstein, I would live longer
if I move fast, so I was speeding" excuse for my speeding violation. So
much for that...

I'am very sorry but as I understand this theory the time inside the ship
goes exact the same speed as outside the ship. You won't live one second
longer. (I guess you will live shorter cause it is quite dangerous to
travel at this speed.)
The only time win you have is relative to the time at a point.
(The point to which you messure the speed.)
This means if you will live outside the ship for 100 years (very optimistic)
you will live inside for 100 years - take a watch a calender with you and
prove it!
For the speeding violation: going 80 miles per hour, 8 hours a day for 40
years will give you a relative time distance of some minutes. No chance
to see the Enterprise.

I agree with the 'PIC controlled particle beam gun' - a PIC is the only IC to
do the job.

For the traveller aboard the ship, your time will appear normal to
you, but will actually be passing slower than for those back on
Earth.  Of course, you need to appraoch pretty close to light speed
to see this happen.  Time dilation can be calculated by:

[1-B^2]^0.5

The B is really beta which is the fraction of light speed you are
travelling, so B=v/c

As you can see, the effects don't become significant unless B is
close to 1.

Actually it wouldn't - you'd end up being a wavefront and having to
deal with interference patterns - just like the movie "The Fly" ?
