I know i never get to travel in a time machine, as i said to myself i would go back to my 10th birthday, and i dont remember seeing myself there.
Time travel is possible, but you need to go faster than the speed of light, which is impossible.
Just watched the Back to the Future trilogy, ready good!. :D
You couldnt go back and look at the lotto numbers as because you were there befor the draw the numbers would be different. These poeple who got all 6 numbers, but forgot to buy the ticket, they wouldnt have won if they did because if they did buy the ticket, due to cause and effect the numbers would have been different.
You couldnt go back and kill hitler, as if you did that, you wouldnt exsist, as you would be changing the corse of time in a BIG way. You grandparents probably wont meet, so you farther was never born. The problem is now you don't exsist, so you couldnt go back in time and kill hitler.
Also if you have watched Hitchhikers Guide to the Galaxy, theres this restaurant that is so forward in time, you can see the end of the universe. Its VERY expensive, but all you do is when you get back, is open a bank account, and put a penny in, by the time the restaurant is made, you own 2 billion pounds. So you can easiliy afford it.
:D
