Strange.

Why do you compare speed of life with age?

"lets say u have a twin brother, and he stayed behind on earth while u go traveling near the speed of light. when u return lets say 10 years later earth time, he would've aged 10 years (obviously), but u would have aged perhaps only 5 years (depending on how close u were to the speed of light)."

i dont understand this statement. Let say If i travel the speed of light. It only take me to certain place(A) much faster that the light. But the time I travel to A will determine my age, not the speed of light.

For example: If i travel to sun in 1 minute. Earth can only see after 3-4 minutes. By that time, I'm already back to Earth. What earth saw was my past (2 minute ago) but present I'm still 3minute older (when earth see me).

Am I right or wrong?

I still dont understant this statement:

1. theory of relativity state that the closer you are to speed of light, the slower your "time" is relatively. IE. if you travel for 10 minutes at speed close to c, then stop, 10 minutes of your time has passed. however, 10 years may have passed for someone at a slower speed.

You mean like this example?

If you got in a rocket ship and accelerated you could go what seems infinitely fast to you. You could travel to a star 100 light years away and get they by lunch, turn around, and get back to Earth the same day. But you will find that everyone else is 200 years (and one day) older than you are. From their perspective, you were traveling very close to the speed of light and it take 200 years for light to get to that star and back. But to you, it was only a day. Your aging slowed down because you move forward through time faster. What you observe as linear acceleration in space that obeys Newton's laws, isn't what really happens. You start out accelerating in space but as you gain speed you start accelerating through time instead. You can only move at the speed of light in space, but can move infinitely fast through time.

WOW. Great explanation. That's what I been thinking (if the statement is right).

"In Einstein's theory of relativity, once you reach the speed of light. Time for the object will stop. "

Time stop. But not life. Human still need to regenerate dead cell , etc.... which mean we will age (biologically).

"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?

Ah... never thought of that.

You mean, Speed of light is faster than nueron signal speed to transmit information for our brain to decode?
