I didn't read them all, too much time. But I did read some of the ones about time travel. I believe time travel is possible, but only into the future. The past brings up too many problems.

An example would be the 'grandfather paradox'. If you went back in time and killed your grandfather when he was young, he wouldn't have had your parent, and you would not have been born. If this is true, you could not have gone back in time in the first place!

But perhaps this happens all the time. Perhaps I once had a friend Bob who created a time machine, and then went back in time. He killed his Grandfather, thus killing himself, his time machine, and my memories of him.

Who knows, perhaps time travelers exist, but our memories of them become erased as they alter the past............ :)
