Bilbo's Questions on life and stuff

[Dizaster]

I remember reading somewhere that if the speed of light did not travel at the speed of light, but infact traveled very slowly,,,,

You could stand still in a fully lit room, but if you took a step forward, their would be black space where you were just standing, and would take a certain time to fill up again with light... That would be fun....

Another one is, if 2 twins were born at the same time (duh), both put on precise identical watches set to the exact same time, then one stayed on earth while the other traveled at near the speed of light and then returned to earth, The twin that was travelling at near speed of light would still look young (in their 20's), and the one that stayed on earth would be old (in their 80's)....
That's only if you consider that their is only one real time... See, if you looked at the twins watches. The one that went into space would have a watch that said 20 years had passed, and the one from earth would say that 80's had passed... So relatively, they are both aging at the exact same rate,,, just the further away from gravity you are and the faster you travel, the slower time goes... (well, relative to earth time that is...)

But then, even earth time is not 'exact'

They tested this by taking 2 very very precise clocks, and placing one at the bottom of a large dam, and one at the top.. If you sat at the bottom with that clock, you could measure that it kept exact seconds..... If you sat at the top and measured that clock, that would also keep exact seconds.. But if you bring them together after a day, the one that was at the top of the dam will be behind the one at the bottom. Seeming that it ticked slower...

If the effects were exhagerated, you could sit at the bottom with your own ticking watch, and look up at the top top clock and see that it was ticking slower, but as you climbed up the dam, they would slowly even up until you reached the same height and they would be ticking at the same speed..

*strange*

So basically, if 2 twins were born, and one went to live on the highest mountain while the other lived at see level, and met back up in 80 years, one would be older (only by a small amount though, compared to the lightspeed example).

We live in a strange strange world....

And this type of stuff freaks me out..
