"If you're in a spaceship which travels in a speed of light from point A to point B and the outside of the spaceship calculate the time as 5 years, you will not feel 5 years cause the time stops inside the spaceship. You will feel a split second arrival. When you arrived, people already aged 5 years older than you. Simple as that.. "

Thats the statement that bother me. If Im travel Point A to Pont B in 5 sec. That's means I'm travel fast (my biological will grow/regenerate/deteiorate for 5 sec). When I reach Point B. Point B wont age (from what I see) for 5 Years because he didnt travel(constant speed), he just age normally.

Consider this, If I want to go to Mars using light speed, I might reach there in 7 minutes instead of 1-2 years. That doesnt means ppl in earth already aged 1-2 years. I just travel/reach Mars faster.

However, if I travel/warp space faster that speed of light to Pluto. I will reach Pluto in 10 minutes but human in earth will only see me after (maybe 1 month) because the light that reflect back is slower that the speed i move.

Althought previous buddy already said my theory is wrong and einstein is right. Yet, I still unable to understand what Einstein theory said and his support. but i like jswong explaination.

Other suggest that example show in GPRS and Clock (difference) from earth and space. But those are mechanical, which probably affected by gravity, electromagnet and etc. What we are talking now is more like biological. And Biologically, a cell need to duplicate at certain period of time. and the "time" here means the nutrient that its taken, used, and regenerate.

If we can stay younger means we spend less time in Speed of light to reach a certain distance/area. But that doesnt mean that if we travel around the world in speed of light for let say 1 minute, mean those who are constant speed in earth age 1 day. To me, its only we cover the earth (round the world) faster that earth turn.

But of course, Unless the show in Superman really works. Where's Superman fly in speed of light and turn the earth the opposite way (means he went back to the past)...zzz

What do you guys think?

I have a question.

why does our biological clock moves slower while moving within/faster than speed of light?

all i can comprehend is that we just move faster with the same speed that light travels.

and.. if our biological clock moves slower than while traveling at the speed of light, does that mean if we manage to stop light from traveling so fast, we might see another form of light?

If 1 million years of travel = feel a split second. Does my body age a split second? Or will my body just die.

We can conclude that time travelling is possible if we(humans) are able to travel in the speed of light.
BUT, what about going back to the past? Is that possible? Explain.

The 'past' that u 'go back' to might not be ur actual past. Its just another constructed universe at which the time is the same as ur past but at a different space/universe. While the space/universe that u left goes on without u.

U then, needs to go back to the time and space/universe from where u left to pick up where u have left before u go back to the 'past'.

The two variables that needs to be locked then, is the time and space, in ur 'time machine' GUI.
