I posted this on another thread but got no response. I am lysdexic and so is my whole famned damily, that is the reason I have trouble with the math.
I would like to ask a question. First I will need to set up three scenarios, these are based on what I know about Einsteins theory stating that
traveling at the speed of light will effect time. Although I do understand much of it, I am lost in the math that explains it.
From what I understand:
Einstein worked out his idea with the use of a magic clock. Einstein used a magic clock in his example because if we were actually moving away from
the clock we would loose sight of it very quickly. What we see when we look at a clock is not the clock but the light that is reflected from the
clock. If we move away from the clock at the speed of light, we would always see the same light particles and therefor time would stop for the people
on the ship that are moving away.
Scenario one:
The occupants of the ship leave Earth at the speed of light. To them time has stopped since they are traveling at the speed of light. They travel to a
star system that is four light years away.
Results:
To the crew this trip would be instantaneous but to an observer on Earth the trip took four years.
Scenario two:
In this scenario we will use the same set up as in scenario one except we will look at the return journey
The crew leave the new world for the journey home. The crew still see the magic clock back on Earth.
Results:
From an Earth perspective the trip to a new world took four years and the return trip took four years.
The crew of the ship would see this completely different. To the crew the journey to the planet was instantaneous but the return trip took eight
years. They are moving toward the magic clock at the speed of light and the light being reflected from the clock is moving toward them at the speed of
light. Just as two cars traveling at 55mph collide at the same rate as a single car hitting a wall at 110mph the collision of the light particles
would be doubled and therefore time would appear to double for the crew.
Scenario three
For this example I will add two new timepieces, a magic clock on the new planet and a wristwatch on the crew member of the ship. Again we will look at
the complete trip to and from the new world
Results:
From Earth the trip to the new world has taken eight years, four years to get there and four years to get back.
To the crew they would look at Earth and time would seem to stop but when they turn around they would see the clock on the new world spinning at twice
the normal speed. The wrist watch on their arm would be traveling or ticking by at normal speed/time. To the crew, the journey to the new planet takes
four years and the return trip takes four years. The exact same as the witness on Earth sees.
As I said, I really don't know much about Einsteins theory but this seems to present a paradox. I hope that a member of this forum has the knowledge
to explain the mistakes in my theory. If I am correct then the whole idea of time traveling at the speed of light is incorrect.
