omg... im not gonna comment. :rolleyes: this is just too funny... im talking about the experiment, not philosophy or whether the hands can stretched to the distance of the train.

you idiots!!! now you gonna drive me crazy... the whole point of the experiment was to test that. i don't no whats the difference ask rene descartes: "all the things one can take as fact stems from the realisation that all facts about the outside world are acquired through the senses. the senses...

why don't you understand? are you just trying to make me angry? what kind of argument is this? don't make me quote the stupid descartes guy. all im saying is whether this length can be felt by hands instead of just rather seen by the eye. ok? hahaha

so it must be physical if you consider them as twins. what is wrong with you? hahaha its a thought experiment damn it. its there to test the physical existence of this length... not if you can actually do it or not. hahaha :p

how might you do that? so they continue to age at different rate when they are relatively at the same speed compared to each other? but this is all gay anyway... have they actually got two twins and tested it?

but did i not say "IF" twin paradox situation is REAL? there are some? its fully concrete if its real... unless you are looking from a philosophical point of view.

i don't know... thats what im wondering about? seriously if that twin paradox thing is real then it should work like that. weird. :p edit: test it? hahaha i'll shoot you at different speeds and see what will happen eh? this is one of them matrix things i suppose... they slow down time LOL :p

lets not argue that here... philosophy is just too much. :p how can you mearsure it then? with a camera then use a ruler? hahaha... thats 100% percieved.

hahaha... who doesn't know that? all Wohzazz wanted to know is whether this length contraction is actually physical or just a percieved thing... if you know what i mean. :p edit: just like the twin paradox... they actually age differently so its physical... but has anyone done any actual...

ok Wohzazz, don't worry about what others say. i know what you mean. if you know the twin paradox situation... the twins age differently when they are travelling at different speed. but they return to the same rate of aging when they are at the same speed relative to each other again... its...

but you have to realise the SPEED has made the two share a different time in space. in my mind the law of themodydamics still applies here... hahaha... time is length in a different form. :)

did you read my post? don't tell me you're not reading it again... hahaha... seriously study hsc man. :p

ok i'll post my thoughts on this... i think it'll fit... if the twin paradox thing works. because all you are doing is transforming the percieved distance, length into percieved time. so if this percieved time affects human aging i don't see why it would not affect the actual length of the train...

what? your dad? hahaha... why is he laughin?

what are you? E albert? are you trying to propose some sought of thought experiment which could lead you to a noble prize? seriously how would you know? no one knows for sure... you can just make crap up... :p

if you think thats funny you should read the past questions with the percentage of people choosing either a,b,c,d. you always see like 10+% of people choosing something like acid is a base... hahaha :p

how? hahaha

what i think is that chemistry is the father of biology. and so too with math is the mother of physics. bio and phy is just specific fields of a larger area of study. :)

i can't even remember which uni i went to... did you have to pay? i got sponsored by the principal... :p

quoting from the first law of thermodynamics: the change in internal energy of a system is equal to the heat added to the system minus the work done by the system. but what happen if the train is heat proof... full proof. nah thats what science engineers are for... is there such a thing...
