here's a often quoted paradox of time:
if i went into the past and murdered my own grandfather before he met my grandmother, then how? i would not exist.. if i did not exist, how did i murder my grandfather?

the bad of travelling to the past is that i will have a tendency to alter it, like as a Singaporean, i would probably want to prevent the Japanese invasion in WW2. However if i did, Singapore would still be a British colony and Singapore would not be celebrating its National Day to mark its independence.
