Dude... that black hole thingy... isn't it a teleportation? I've seen some scientist done it with a small particle successfully in one Japs channel (for all I know, some gundam or macross may pop up soon... yeah right

)
I see them work means I believe in teleportation... however, time travel? IF you are correct... WHAT kind of energy we can use? Blackhole is known as a died star.... to create one... well, you do the calculations...
...enough ramblings...
I see no point in going to the future or the past. Not because I am satisfied here... I don't see a reason to go there... that is all.
Future is bleak... what I see is not my future (if I go) yet. It can be amusing, but I will lose my motive to strive or choose (like playing a hentai game using a faq).
Past? Maybe I will kiss that girl this time... maybe I will do it right. Maybe I will kill Hitler... dude... it is pointless, just more regrets along the way... if you busy changing your past, you will lose your view of the future. See Back to the Future for reference...
