Travelling in Time

This is my response on Blogcatalog to a question on the possibility of time travel, brief and to the point.

Well, to believe in this stuff one would have to conceive of time as a stream linking the present with the past and the future. All of our actions are therefore foreordained and there is no freedom at all. A time machine has already been invented and the future comes back to the past; we are the past; we are already dead. :-)
